IB Biology - Today we examined our last piece of research and for some of you this was hard. I know you want to do well, but this does require a lot of work. For the SL topics you need to continue to come prepared, after the readings, with your lingering questions. The SL topics (1-6) are a review from your freshman year, but your HL topics (7-11) we will go over in deep detail. Regardless of the level we must all engage. I mentioned to one students that there was a question on the exam from last year that was an entire page long, but really only relied on you knowing the fact that small molecules move faster through a gel than large ones. IB is about thinking deeply and that is HARD! I say this because I want you to come to me and engage me with your questions, and I will continue to engage you with challenging questions. For tonight I want you to finish working on your videos and to bring me your questions about your assigned chapter.
Honors Biology - Today's video on muscles: https://www.youtube.com/watch?v=94Q-fvCAJzQ Hopefully you were able to get the basics about how muscles move. In class you should have also read the article that I posted at the bottom of this blog to reinforce the ideas we saw in the movie, but also to see what happens to the muscles of people who have DMD. So by tomorrow you should have drawings on the right which reflect healthy muscle, but on the left side of your entry you should have mirrored drawings but with what the muscles would look like with DMD. Don't forget that your illustrations should be accompanied with explanations of what we are looking at, color, and "clean" labels.
If you would like to learn more about muscles, try playing around on anatomy arcade at: http://www.anatomyarcade.com/games/PAM/PAM.html
IB Biology - Tonight I want you to complete question 4 on page 60 and questions 1 and 2 on page 139. These are review questions. These should be ready to be turned in on a separate sheet of paper. In addition, your video should be near complete or finished. I would like you to email them to email@example.com because it will be easier for me to utilize. If they are massive in file size, please bring it on a thumb drive.
Honors Biology - Today we took a short break from our research on MDM and got a briefing on macromolecules since we are talking a lot about proteins. This "cheat" sheet went in on the right side of an entry and on the left we started to make drawings on each macromolecule type. You will finish the drawings tonight if we didn't in class and then find 3 everyday substances that fall into each category. Yes, that is a minimum of 12 total substances.

IB Biology - Tomorrow is your next big unit exam and will be on water and macromolecules. I answered every question you might have but the list is still posted on last Friday. As to the project I introduced today, I know it looks like a ton of information for this week, but we're going to be splitting it up so don't worry. You and your partner(s) will be making an entertaining video on your third of the content (7.1, 7.2, and 7.3).

Tertiary Structure: R-group interactions for folding
Quaternary Structure: More than one peptide chain
Prokaryotic vs Eukaryotic translation
Honors Biology - Today we started by reviewing the criteria for, and grading of, your final unit assessment/project. You will eventually (Wednesday) be placing this work onto a poster paper for public display so make sure you do it well. You must address each of the criteria (which is still listed on last Friday). Tomorrow we will work on your reflection.
IB Biology - Today we took a Macromolecule Unit exam. Tonight I want you to do two things. 1) I want you to work on your video on replication, transcription, translation. 2) I would like you to thoughtfully respond to DBQ 353, and TOK 347, 351. Please be prepared to turn it in so put it on a separate piece of paper.
Honors Biology - Today we spent our time working on our final assessment, but you added the final piece, your reflection. This reflection should include 1) What was easy for you. 2) What was difficult to understand. 3) On a scale of 1-10 how effective was your learning this unit and why? 4) What would you like to know more about?
Oh, also you should highlight, underline, or enlarge text for each topic that you have written up for your final assessment/case study so it is easy to put this together tomorrow.
IB Biology - Dear IB Students, the following link is from Mr. Davis and is the form that you need to fill out in order to register for your May tests. Please be sure to fill it out before the 26th of October as that is our deadline. LINK
As to continuing our understanding of replication, transcription, and translation I want you to complete DBQ on page 358. Please know that you should read the question, identify those parts that your are unclear about, read those sections of the book, and then attack the prompt. Please don't freak out if you struggle, just write your questions and I'll address them on Friday when I return.
Honors Biology - Today we spent the entire day putting our final unit projects together. Sheesh! That took longer than I expected. Regardless, that's done and you have NO HOMEWORK tonight!!! Yes, it is one of those rare occasions. Tomorrow you will have a substitute and I will be at a conference. They will be doing a piece of work with you that will help us start to think about our next unit.
IB Biology - OUT TODAY. You should have worked on your video projects today, but tonight I need you to go through the same process as yesterday to attack the DBQ on page 369. Read the DBQ, Find what you are unclear about, go back to the question and do what you can, and then write questions for what you don't know. Always attempt what you can though. This will be turned in on Friday so do them on a separate sheet of paper. ALSO, By Friday you should have a content script pretty much ready to go for filming. Please come prepared with a fairly solid script. Yes, you need to get workin!
Honors Biology - Today you had Mr. Vint covering your class. You took the concepts of atoms, molecules, macromolecules, cells, tissues, mitosis, DNA, mRNA, helicase, polymerase, and genetics and found information on these and then made illustrations for each and then showed their relationship to each other using lines and with connecting statements written on those lines. There is no one right way to do this, but you should have all concepts illustrated, color coded, connected with lines, and then relationships explained on the lines. This is all due tomorrow when I return from my training, please don't give me excuses instead.
IB Biology - Today we got caught up by discussing the basics of DNA wrapping (https://www.youtube.com/watch?v=dKubyIRiN84) and then looking at other visualizations on this site to see the structures n 3-D. http://www.rcsb.org/pdb/results/results.do?tabtoshow=Current&qrid=6EA3B81A In addition, here's the walk through on transcription and translation, http://www.phschool.com/science/biology_place/biocoach/transcription/premrna.html. It doesn't show everything you need, but should give you a good frame work for understanding the process. This weekend you need to make sure that you are ready to go with your video. On Monday we'll take a look back at the lab reports you produced. ...you should also come with any other questions you may have.
Honors Biology - Today we started by watching a video about kids with some disability. Some of you were able to add insights to living with disabilities. We then discussed questions that you developed about these kids and what questions we would ask to find out what is going on with these lids and we prioritized them to find out what we would need to learn about next. It turns out that after careful conversation with you that with everything we observed the problem seems to boil down to issues with the muscles, so that's where we'll pick up on Monday. Have a great weekend.
IB Biology - Please read the following article and while reading this I want you to use the information found in chapter 2.6 and 2.7 to explain the article paragraph by paragraph.Protein Synthesis:RNA hidden regulator https://www.sciencedaily.com/releases/2018/07/180716114529.htm
Your explanation should include:
The Structure of Nucleotides, RNA, and DNA
How is mRNA formed. What role it plays?
What is the function of nucleotides and how that relates to codons?
How regulation works in protein synthesis
Why could the content of this article be an issue, but also how might this help us?
What does 3'-5' mean and why is this importan?
How does Chargaff data connect to this article?
This will be due on Thursday so be sure to come prepared to ask questions each day as you come to class.
Honors Biology - Today we took a long look at the research you completed this lasts week. Wow! I found a lot of interesting data. In 3rd period I learned that eating complex carbohydrates the night before, consuming simple carbs can be useful in a shorter duration, and that deep breathing, while it may relax us, does not help us with the oxygen needed for push-ups. Turns out that elevated breathing helps gas exchange.
BUT we still had a lingering question about how our muscles slow down and burn no matter what we do. We then got a chance to see what actually is happening when we don't get enough oxygen. Since we didn't get to finish this today, tonight I want you to just go to the left side of our entry and find out two ways that an athlete can improve the lactic acid/lactate tolerance.
IB Biology - Today we continued our work in the lab. Please make sure that any modifications to your procedures is accounted for in the final lab report. Tomorrow will be your last day to collect data. IN the meantime, I need you to attach the next questions/concepts to the article I assigned yesterday. Please be sure to tell me how these are connected to what is in the article. This will be turned in tomorrow. Semi-conservative Replication, Meselson-Stahl's experiment (see DBQ113-114), and helicase vs polymerase are all concepts to be tied to the article. I am very concerned at the completion rate for some of you.
Honors Biology - Today we continued the conversation about fermentation and then discussed homeostasis and feedback in the body. This is all we need to know at this point! We are sooooo close to the big unit assessment, but before we get there we'll being doing an intensive case study which will set us up. Tonight I want you to find more examples of feedback and how that feedback helps us maintain homeostasis. You must have an example of positive feedback and negative feedback, so two. Yes, you should explain how the feedback maintains our homeostasis.
IB Biology - Today we continued to discuss the article and the many parts of replication, transcription, and translation. There are few things more I would like you to briefly add to your understanding: How does PCR work and what is it useful for? and How is insulin grown via bacteria? Do these actually relate to the article we read?
Tomorrow you will have an opportunity to ask more questions and to finish your homework and your lab. The lab will be turned in Friday, but the homework is due tomorrow at the end of class. Your unit test will be pushed to early next week, Monday or Tuesday.
Honors Biology - Today you reflected on feedback and homeostasis first and then were introduced to the case study that should prepare you for your unit final. This case study on an athlete (2000 meter row) should be worked on and will be due by Friday. You can find an electronic copy of this case study below in case you were not in class. Tomorrow is a short day so make sure to come prepared with questions that you may have on the work. This is very similar to what your unit final will look like.
IB Biology - Today we covered everything from 2.6 and 2.7, the article, and the connections. Tomorrow you will need to submit your finished lab report. This lab report should be modeled after our last lab having raw data, processed data in the form of a graph, as well as a test of data validity in the form of a t-test. We will also do a review tomorrow of all of the material that will be on the unit exam which will be on Tuesday.
Honors Biology - Today we started by looking at your lab reports. Nice work overall, but this first formal lab is an assignment with low risk. If you chose, as an individual, to redo your group work, please make a copy of your groups' lab. Next, Take pictures (or take the corrected lab), open a copy of the lab write-up checklist, and make your corrections. If you choose to do this a hard copy must be resubmitted to me tomorrow. Any identical papers will result in a zero for both people. Lastly, while I spent a chunk of time covering the 2000m Row case study, you should have all of your answers completed for submission tomorrow.
IB Biology - The following are all of the topics you should familiarize yourself with for our unit exam. The exam will be on Tuesday so please be sure to note any last minute questions you may have so I can respond to them on Monday.
Properties of water
Cell membrane structure
Carbohydrates - mono/poly
Lipids - Structure fatty acid
Ratio of components
DNA vs RNA
(Your next test will have much of this)
Honors Biology - Today you started a new entry titled, " Your Case Study - A Unit Assessment"
This Final Unit Project will probably be in the form of a presentation poster that shows the following:
Condition of your choice. Athlete, flu patient, infected wound.
Specific cells affected
Medical history (optional)
Cell function including membranes.
How glucose is used and constructed
How cells get what they need.
Does fermentation happen?
How do the components cycle back to plants?
How feedback in the body helps maintain homeostasis?
Can you engineer/prescribe something that is more effective in preventing or promoting healing?
Reflect on your understanding of sickness and health as a final piece.
Bonus to get the Five!
Include multiple condition, genetic issues, immune response, etc.
BY MONDAY you should have your case study laid out. In other words, you should know what you are doing as far as who the patient is and their condition, as well as a basic idea of how your content attaches to this person's condition.
IB Biology - Today we started by turning in our homework and finishing our protein introduction. I then touched a little bit on enzymes and how we would be designing some research on enzymes that focus on Lipases, proteases, and amylases. You selected your groups and tonight I need you to prepare for this by being familiar (i.e. know them well) with the following concepts found in chapter 2.5 and 8.1. Be sure you know about the many examples (DBQ 100) that might inspire your enzyme research. AND BE SURE to know about the lactose free milk on page 105.
Honors Biology - Today we put some pieces together for the next question we had which was where does the glucose come from and how does it store energy? You turned in your POGIL from Friday, we then discussed the results, and finally made drawings of chloroplasts and the photosynthetic process. Tomorrow we'll start getting back into the athletic process and so I need you to think about cellular respiration, photosynthesis, heart rate, and respiration rate, etc. and how that would look if you were going to manipulate one of these factors. In other words, much more simply put, what could you do, knowing what you know, to an athlete that would improve their performance? If you could only change one thing to prepare them for an athletic event, what would you change and why? Write this on a piece of paper to be turned in tomorrow.
IB Biology - Today we made sure to address your questions about enzymes. You asked some fabulous questions and I think you're ready for the quiz tomorrow. While we will take the quiz on 2.5 tomorrow, we will also go into the design of your lab. Tonight you and your partners should have isolated your fundamental question you will investigate. This along with purpose, a title, and a hypothesis. This should be on a shared document that you can all contribute to! As you design this lab, be sure you really understand what is found on pages 100-104. It's all about labs!
Honors Biology - Today we started our day with a recap of what we know and how our latest process of photosynthesis relates to cell respiration. We then discussed our lab where we'll attempt to improve our athlete's performance.
BUT, of course, we first needed to tackle the ethics of experimentation. We'll be working on athletes, but I asked you about your opinion on using animals, and primates, and humans. On the left side of our entry, on the top half, I asked you about experimenting with cells. Kind of an odd question, but tell me what you think. Directly below this, on the bottom half, I want you to give me a general guideline for YOU. What is and isn't acceptable in experimentation for you. Please note that our stance at high school is one where we never put animals in any situation that could cause them harm.
Lastly, we will start taking baseline data on your athlete tomorrow. To prepare for this I want you to go through the list of factors we could change and to decide on the top two factors you want to experiment with. Remember that you want to affect your athlete as much as possible, so pick well. To do this I want you to highlight your top two choice from the list we made today.
IB Biology - Today, after taking our quiz on enzymes, we spent our time developing our enzymatic reaction lab. At this point you should have sent me a materials list for the kinds of lab ware that I can provide. You should also have all of your initial work (title, hypothesis, purpose, etc.) completed and ready to be utilized/tested. Please understand that you will be turning in a group report. Oh, also understand that we will continue to learn new metabolic processes as we do this lab. Be ready to go tomorrow.
Honors Biology - Today our whole purpose was to write up our shared lab report on increase the performance of an athlete (How to create an overnight superstar). If you follow the lab report guidelines below, you cannot go wrong, USE THEM! If you want to see a really nice example of a lab, you also have a sample on the "Online Resources" you can look at one. It's not on this topic, but it should give you a good idea of the proper format!
IMPORTANT! I noticed that many of you did not collect baseline data on your test subject. DON'T WORRY. You can collect this data tonight once you have established your procedures. You only need to have your lab report up to part 5, this baseline data collected for tomorrow, AND whatever treatment you will do to your athlete.
IB Biology - SO the finalizing of your lab write up should have happened today. You made sure you used metric measurements, the procedures were easy and clear to follow, and you have your materials. In the meantime, while we experiment, we need to continue to learn new content. For this week I want you to do the following: Choose one of these these supplements that people use to improve their lives. Next, I want you to look at the EVIDENCE of their efficacy. EVIDENCE.... you may find that here is little, or that it is incomplete in what they report! Be a good skeptic. Please look at three sources that are not the manufacturer. Here's your list to choose from, but you can also do any other product that is not on there.
Glucosamine and chondroitin,
Alpha Lipoic acid,
...and MANY more.
Once you have the research, tomorrow we will put it into a format, so just worry about collecting data.
Honors Biology - Today was a big lab day! You collected data on your treated athlete. Do NOT be concerned if your data does not come out as expected, this is good data too. Your only task tonight is to create a data chart using the shared document you created in class. Now take the data table and the bar graph and paste it into your document. If it isn't perfect, don't worry. We can clean it up later.
IB Biology - Today was day 2 of your experimentation. This entire lab will be due on Thursday of next week, please make sure you are doing what needs to get done. For now, I need you to finish the assignment you started last night. Using page 84 and the research you have done on your health supplement report to use by creating a One Pager. This is one piece of paper that has the name of the product, pictures related to it's supposed cures. I want you to tell me about the implication and limitations of the evidence for the product. I want you to also include an illustration, and report the data. Make a nice border, and then include something about placebo effect and the mind/body connection that might play a role. As long as you have these components, you are great. One page, that's it! Oh, one side of one page. Make it beautiful.
Honors Biology - Today we started our day discussing the Nobel prize in biology. We then discussed our homework from two days ago about how we feel about experimentation on cells. The reviews from you were mixed, but then we watched the short video on Henrietta Lacks (https://www.youtube.com/watch?v=eW_0ZMEYAQI) and your responses changed a little bit. Remember, your opinion is your opinion, but I hope you have solid reasons for what you believe. Well, anyway, the last thing we did was t review your data and the graph you created. And lastly, you created a conclusion. Your lab is due on Monday. ONE HARD COPY from your group. Please make sure that you and your partners carefully use the lab write up guidelines found below.
IB Biology - Today we went over all of the things we failed to accomplish on our lab reports. I actually posted those points on last Friday's blog. You have until Thursday to make any correction and resubmit. I won't chase you around about it. Then we went over the DBQ's that were assigned and discussed the depth needed in interpreting data. Lastly, you worked on your drawings. Your drawings are due tomorrow. We will be taking a quiz on Wednesday on 2.1, 2.2, and 2.3.
Honors Biology - Today you came back with the prepared questions from the quadlicious triathlon! And you GET IT! (It=so much about how the body works. It's starting to come together!) After looking back at our animal cell illustrations and identifying the mitochondria, we then drew a cut away illustration of the Mighty Mito on a new entry. While we didn't get more done, we'll finish this tomorrow.
On the left side of entry I want you to find out about two medical conditions that are related to mitochondria. You should describe the condition, find out how the structure of the mitochondrion is affected because of this condition (use your drawing to describe), what treatments can be used to help these patients, and don't forget to site your source next to your 2 conditions.
IB Biology - Today we spent he big chunk of our time looking at your work. We looked at the many iterations of carbohydrates and lipids. At this point you should have a pretty good idea of the differences. So, tomorrow you have a quiz on the material from 2.1, 2.2, and 2.3. As to looking ahead, we next head to understanding proteins. In order to do this I want you to watch this great review!
https://www.youtube.com/watch?v=H8WJ2KENlK0&vl=en It also answers the question we had about fructose and glucose! After about the first 10 minutes it gets into proteins that we haven't yet studied, but we will starting tomorrow! Feel free to take notes!
Honors Biology - So today we finished answering our driving question of how mitochondria provide us with the energy our cells need. When we use this information in conjunction with the 4-event triathlon you should be putting together a good ide of how our systems work together to allow our athletes to do what they do! ...which is what your formative assessment is about. Tomorrow (due on Friday), you will begin creating an illustration of how is it possible for the athlete to have done what they did. You must include the following concepts/topics: Digestion, Respiration, Heart Rate, Circulatory system and blood, Cells, Mitochondrion, Glucose, Oxygen, Water, Carbon Dioxide, ATP, and Energy. Oh, and be sure to include the FORMULA! You should illustrate your response as much as possible, but written explanations will support these drawings. Here's a great video from Khan Academy. Watch this and take notes to work on your project tomrrow: https://www.khanacademy.org/science/biology/structure-of-a-cell/tour-of-organelles/v/mitochondria-video You should know that this project will NOT be in your notebook, but submitted separately.
IB Biology - SO today we took a quiz on carbohydrates and lipids, 2 of our 4 macromolecules. Today we began a project on the third of our four macromolecules (do you know the fourth?). This project is focused around proteins (Chapter 2.4). A shared document was created in class for your class for you to put your information into. Your talking points should be placed in the speakers notes area of this Slides presentation, but your visuals should support what you are saying. The following list shows the ORDER as well as the topics that are required for this project.
X Structure: Amino acids (origins, structures, types and sources), peptides, and Polypeptides.
X Coding for the proteins. Proteomes and genomes. Which is bigger? How?
X Functions:Examples and connect to structure.
X Insulin, Rubisco, Collagen, and Immunoglobulin.
X Denaturing through pH and Temperature. How does it actually happen?
X Find out about BOTOX, pg93. How is this connected to proteins? What other products are made this way?
X Other protein related topic, your choice! Folding?
This is all DUE FRIDAY!!!
As to homework, please review membrane structure and histamine receptors for the speaker tomorrow. Develop questions (potential for extra credit if you have good questions!)
https://www.youtube.com/watch?v=YS2lipwoMgg And don't forget that we'll be meeting in the LITTLE THEATER so do NOT go to room 187.
Honors Biology - Today was mostly a work day, and on Friday the project is due. Be sure you carefully review ALL of the required parts necessary to the project/assessment. They are listed on Tuesday. IN addition to this project, I need you to also review membrane structure and histamine receptors for the speaker tomorrow by watching the following video.
https://www.youtube.com/watch?v=YS2lipwoMgg If you have a really good question for our speaker there may be some extra credit for you! Oh and don't forget to meet at the LITTLE THEATER (not room 187)!!!!
PATHWAY STUDENTS!!! Please check out the following website for the newly posted opportunities (which some are required) list on our official webpage (bookmark it!). sites.google.com/guhsd.net/ghdhealthpathways/work-based-learning/events-opportunities?authuser=0 This could cover your volunteer hours, shadowing, or an internship!
IB Biology - I hope you liked the guest speaker today! Please be sure your slides are ready/finished/ready to be discussed!
Honors Biology - I hope you enjoyed knowing a lot about our guest speakers topic! Please make sure your illustration is ready to go tomorrow. Yes, finished.
IB Biology - Okay! Well, today we had a chance to hear a general overview on proteins, but didn't get through it all. We'll pick that back up on Monday. But one of the functions of proteins is their role as an enzyme, a catalyst for reactions. Please complete the DBQ found on page 97. This will be turned in on Monday.
Honors Biology - Today we spent a CHUNK of time just talking about how we need to take control of our lives and to explore all of the opportunities that high school offers! ...and that everyone should play water polo. But for this weekend you should complete the POGIL you received today on the connection between photosynthesis and respiration. It is due when you walk in! If you were out for some reason, I will post it below.
IB Biology - Hey IB! I'm so excited! I'm so excited! After some research it turns out that the Sheets T-Test actually does ALL of the work for us and is actually giving us our P-VALUES!!! This means that you should be considering any value of less than .05 as significant! Yeah! Thanks Sheets! So should you compare each test to another standard? Yes! Could you instead compare potato molar % mass change with your other tissues of other molarities? Yes! What do you think is best? Please come to school tomorrow with your data and graphs completed. We will complete your conclusion and evaluation by Wednesday so you are free to get ahead. What should be included are the Conclusion (what you learned), An evaluation of the process, and how you would improve the investigation.
Honors Biology - Today we were able to see that sea water can really be a problem for people, but not for specially adapted aquatic animals and plants (like mangroves). So I had actually planned on getting much farther today, but we really didn't get that far on the POGIL on osmosis. SO, tomorrow we will pick that up again! I want to make sure you really get it because a lot of people don't and it is really important for understanding many biological functions. SO what's for homework? The answer is nothing, but if you could create an illustration (with color) that uses NO words to explain osmosis, I might consider giving you extra credit if your illustration is effective. Maybe a wordless, step by step? Good luck.
Cool Opportunity for you ladies!!!: Registration for the Cal-JAC’s Fall 2018 Career Expos is underway! The Cal-JAC and its Commission to Recruit Women for the Fire Service are hosting another round of Career Expos for prospective firefighter candidates this fall in Sacramento and San Diego! We encourage our LEA partners to attend one of our upcoming Expos taking place at our Firefighter Candidate Testing Centers (FCTC). We also encourage you to help us increase interest at your respective agencies, by sharing the attached electronic flyer. Expos are free to attend, and are for everyone, but the Cal-JAC is committed to encouraging women and other underrepresented groups to participate.
Expos present an excellent opportunity for both community and firefighter candidate outreach. Cal-JAC participating fire departments have the ability to reserve booths and pass out recruitment materials. Attendees get a face-to-face introduction to the fire service by speaking with recruiters from fire departments throughout the state and the JAC’s Women’s Commission about what “A Day in the Life of a Firefighter” entails. They can try the Candidate Physical Ability Test (CPAT), get hands-on experience with mechanical reasoning props, learn what to expect on the written test and view apparatus displays. Prospective candidates include those from Community College Fire Tech Programs, the CSUS, EMT and Paramedic Programs, U.S. Veterans, Fire Explorer Posts, High School Students, and other fire-related organizations and associations.
Please see the following Expo details below:

San Diego Expo Registration
IB Biology - We are almost there. This data processing has been a tough road for some of you, but at this point you should have all of the data laid out, a graph showing your two sets of data in this graph and uses trendlines to 'smooth' our data, as well as standard error. Since we are limited to using a constant error on Sheets I want you to decide to either use the mean of the standard deviations (not exactly accurate), or the stand deviation of the standard deviations. Tonight you will also write your conclusion, your evaluation of the procedure, and how you would improve the investigation. You are working as a group so divide up the work. All of this is going to be due on Thursday. ...yes, I changed my mind. Since you have this extra time though, I need you to review chapter 2.1 and 2.2. These should be review and you can probably use your freshman notebook to help, but come prepared with questions as you should already know most of it. Please also understand why the synthesis of urea was an important landmark in biology
Honors Biology - Today we started by making sure that everything in your POGIL was on the right track. We then put all of our processes (Diffusion, osmosis, etc.) together in one entry. Then on the left side of this entry we listed the parts of blood: RBC, WBC, Platelets, and Plasma. Tonight, in each of the boxes we created for each blood component I want you to find out the function of each of these components and write a one sentence summary of this function in the appropriate box.
VOLUNTEER OPPORTUNITY: Please pass on the word to your students -- El Cajon Library is looking for high school volunteers, and our first volunteer meeting of the school year is this coming Sunday, September 23, at 3 PM! We'll discuss the fall season, our available volunteering positions (shelver, activity leader, craft prep crew, etc.), and shift times.
The next day, Monday, September 24 from 4-6 PM, is our orientation for those who are interested in working specifically as an After-School Leader on Mondays and/or Thursdays. After-School Leaders help kids in grades K-8 with homework, lead storytimes and crafts, and organize indoor fitness activities. It is a great opportunity for those who are interested in going into education or careers working with children. We are especially looking for Spanish and Arabic speakers! We have up to 8 available slots for Monday and Thursday. A flyer for the orientation is attached.
If a student can't make it to one of these days but still wants to volunteer, they can e-mail me at firstname.lastname@example.org
IB Biology - So today we did a crash course on chapters 2.1 and 2.2. I hope you were able to grab onto the basics of metabolism and the properties of water. Tomorrow your lab report is due. there will be one hard copy turned in for your entire group. As you put your final touches on your report you should probably review the DBQ found on page 42 of your book. This asks you to analyze data that is very similar to yours. At this point you should be able to answer those questions anyway. Put yourself to the test.
Honors Biology - Today we started to wrap up our big idea of why we get sick and tomorrow we'll discuss how to stay health and then move on to your next BIG question of where does cellular energy (ATP) come from? So far you know that we can get sick from bacteria and viruses. You know that we are affected when they come in contact with our cells and assault the membrane. We know that these membranes are complex and have many features that help keep some things in and other things out!
Tonight I want your parents to review the work you have done. First UPDATE YOUR TABLE OF CONTENTS! Next, in the back of your notebook, you will have your parents fill out your parent input page. Your parent should use the rubric on the left and then select a score for your work, write a comment to YOU about your work, and finally sign the first grading period section. Oh, and if they have questions, just answer them!
IB Biology - Today we reviewed the 1st unit exam. Next we jumped into our speed review of the first few section of biochemistry. To review this material we will be doing a poster project! Yeah! FUN! ...right? In any case, the following must be displayed in a graphic format using color.
Hydrogen Bonding and macromolecules
Draw and identify the variation and types - Poster project
Start with the activity on page 65
Carbohydrates - CHO
Differences between Glycogen and amylopectin
Lipids - CHO
Why do these stash so much energy?
Saturated and unsaturated
Mono and poly
Cis- and trans-fats
Coronary Heart Disease and BMI
HW: Blood composition and interactions due to polarity, page 72. Add to poster
Honors Biology - Today we started out by looking at your last test paper and collecting your parent input. Next we recapped that we know how you can get sick, but then asked ourselves so how to we stay healthy? While there may be many, we came up with 8! You asked amazingly good questions and we took some notes. On the left side page of the entry, I want you to create a public service message on health that summarizes what you think are the top three things to consider in maintaining health. This should be colorful, contain three concepts from our list and deliver a message to the reader. Now, tonight I also need you to plan your outfit for tomorrow! Yes, I know this is a weird request, but you need to have good shoes and comfortable cloths on so you can complete your triathlon tomorrow! Yes, Triathlon. ...Casey Triathlon. Be there! Be Square!
IB Biology - Today we took a moment o be introduced to the rubric for IAs. You used these to evaluate another groups work and you probably have a good idea of your strengths and weaknesses are. I just finished marking them and there are some things that were consistently off the mark. 1) Almost everyone's conclusions are weak. Almost none discuss validity of the data (TTEST) and the trends are superficially discussed. AND what does it all mean??? 2) About half of you have not included your uncertainty in measurement?! 3) Some of you graphed incompatible or data that doesn't carry meaning. We'll discuss these on Monday and you'll have a chance to redo your work next week. ...IN the meantime, I want you to continue your carbohydrate and lipid work. Some trends should be coming clear. IN addition, I want you to complete your work on calculating your BMI. You can find this information on page 80. You should then complete the DBQ on page 81. Follow up with a reading of the content on page 84 and then complete the DBQ's on 85 and 86. Be ready to share your responses with others and then turn to it in.
Honors Biology - Today you were all super privileged to have taken part in the very first Casey Quadlicious Triathlon, the only triathlon in the WORLD that has four events! But before you ever jumped right in the competition we discussed last nights homework in terms of anything that might have come up that we hadn't thought of yesterday. You came up with stress release, mental health therapy and investing in good relationships as all other ways to stay healthy! GOOD WORK!
We then shifted our gears to "Where does energy for something like a Quadlicious Triathlon come to power our cells?!" We know that organisms can be reduced to organ systems, and organ systems to organs, and organs to tissues, and finally from tissues to cells, but how do those little cells get that energy and where does it come from?! So, of course we had to do the triathlon and you all were amazing. You decided that respiration and heart rate would be the best way to measure the energy output in your athletes. Now, on the left side of your notebook, I want you to answer the following questions as best you can. Much of this can be answered with what you already know!
1) What was the heart rate and respiration rate change?
2) How did these changes compare between your two athletes?
3) Who do you think burned more energy and why? Use the data and your brain cells
4) What role did the circulatory system play in this?
5) What job did the lungs do in this event?
6) What all did the cells need during this event?
7) How do the cells get what they need? Think membranes and systems
8) What part of the cell gave the cell the energy to be so active?
* you don't need to write these questions, but write your responses so we know what the question was.
IB Biology - Today was a massive data collection day! You got final masses on your tissue samples and also wrote down qualitative data such as floating or sinking, odors, disintegrating tissues, etc. When you come in tomorrow, I want you to be prepared with questions for our cell unit test. I'm passing on our 1.5 and 1.6 reading quiz and want you to really prepare for this unit exam so do not blow this off! The unit exam will be on Wednesday and you will do GREAT!
Honors Biology - Today we started by looking at he article I gave you on Friday. What a trippy weird idea that bacteria can produce proteins that literally embed themselves into membranes of our cells and then bust them open. Kind of scary really! We then do a group activity of membranes and prepared for another big quiz which is on cell membranes and how we get sick. Tomorrow you will be asked to write a CER (Claim, Evidence, and Reasoning) Paper. In this paper you must make a claim about how we get sick from bacteria and viruses and you must include the parts of a membrane as well as ways in which microbes attach and attack cells. You might also discuss sizes, and your evidence can come from many places such as the article we read, the video game we played online, or our microscope work, as well as anything you might find tonight. To score the maximum points possible you should include everything I've mentioned and use reasoning to show how they connect, but note that you will only have one class period to complete this so you should probably pick strong examples. Many people in the past have done an outline before you get to class. You are welcome to do this on the left side of the entry where we did the article. You are going to do great! ...if you prepare.
IB Biology - So today was your big unit exam review. I think we covered everything you need to know, but one way that you can make sure you get it is to try and think about how these topics connect. Some will connect better than others, but all of the concepts connect. When you come in tomorrow, I'm sure you will do well.
Honors Biology - Today we really only took our first big exam on cell membranes and how that relates to how we get sick. This is your first big chunk of points towards your grade and I think we've done well. Tonight, in preparation for tomorrow, I want you to simply ask yourself the question of WHY. Why do bacteria and viruses attack our cells? You don't need to write it down, but I do expect you to have it locked in your brain so I can ask you tomorrow. Be sure you have a response.
IB Biology - Today you took your first unit exam. I hope it was challenging but doable. You are all very smart, and if you have been applying yourself should do very well. In preparation for tomorrow we need be ready to move on to finishing your lab reports through the use of statistical analysis. SO, before tomorrow, be sure to have ALL of your data prepared. This means all quantitative and qualitative data is listed. You should also have % mass change calculated. If you want to get ahead of the game you could also look at the standard deviation for each molarity. We'll be using this as a description of error (error bars).
One last thing! I've already said it once, but I'll say it again, make sure your procedures reflect what we have done. This will be a major sticking point for me! The lab I gave you was meant as a model, not as something to copy.
Honors Biology - Today we picked up our work (the group packet) from Monday looking at how these cell membranes work. Tonight I want you to think about the following situation. If two men were lost in the wilderness and one was lost in the ocean, and one was lost in a vast freshwater lake. Who is in more critical danger? ...and more importantly, why? Your ideas should be written on a piece of paper to be turned in.
IB Biology - Today we reviewed our statistics in order to do the next step in our lab write up. To be prepared for the graph you will need to have percent mass change, mean percent change, and standard deviation for each molarity and tissue. If you just follow the sample I gave you last week you should be all up to date. Oh, but just leave the T-Test for later. BTW, I would highly encourage you to use a spread sheet.
Honors Biology - Today you submitted your ideas about yesterday's scenario. We discussed the ideas and why they had merit. Next, we decided to investigate this in a very real way, well, okay, we used little potato people and listed our factors on the right side of a new entry. These were placed into different solutions and we'll see what they are like after 24 hours. Next, we discussed the various things we know about water and how our scenario is different from real life. Lastly, we wrote down a hypothesis and rationale of what we thought would happen. This occurred on the left side of the entry.
Your job tonight is to think about the following questions. You will put your responses right underneath your hypothesis and rationale. The question is, "When is water VERY important to the body and why?" and secondly, "When is water VERY bad for our cells and why?"
IB Biology - Today was a special day where we learned the power of a spreadsheet! I believe that you are on the right track now. ....I believe. When you come in on Monday we should be able to calculate the last thing we need to do which is the Student T Test which our spreadsheet can do for us! ...if we have the right data. So, you should have figured out the mass change from initial to final, the mass % change of each sample, the MEAN mass % change, the standard deviation (for use with your error bars on your graph. Lastly, create a graph using the data. If you really don't get the math, please come prepared with your questions. We are behind the 8-ball right now and need to pick up the pace! We are going to fly through our next unit!
Honors Biology - WOW! Today we learned all sorts of stuff about water! We learned that you get have too much, too little, that cells can explode, and that water will help regulate our temperature, BUT ....why? Some of you told me about a process called osmosis. Some of you told me about solute concentrations. We talked about isotonic, hypertonic, and hypotonic solutions. We discussed the tragic radio game as well as the tragedy of the USS Indianapolis. And when we looked at the 2 potato people who were lost at sea/lake we realized that the lake person gained weight, and the ocean person had lost weight. But who should we save first? We still aren't positive, which is why we started the POGIL practice. We'll finish that on Monday, but until then I want you to try and answer a couple questions. Your answers will be written right under the homework from last night. !) Why can't we drink sea water? and 2) How do aquatic animals (fish, sharks, etc.) survive in an ocean or freshwater lake?
BONUS EDITION: The following are events coming soon. By attending these and taking 3 selfies with different signage and your watch in each picture, I'll give you extra credit!
1) This is the 40th anniversary Job Fair at Grossmont college on October 12th.

3) Kids Care Fest Volunteering (community service hours!) on November 3rd from 9am-1pm at the Lemon Grove Recreation Center. I'll let you know about this one once I get more information.
Monday - Holiday
IB Biology - Today we started to work on our first deep investigation that relies on what we are learning, statistical analyses, and is an introduction to how to write an IA. You can find a pdf of the paper I handed out at the bottom of last week's postings. You should have divided up the material among your group and created a shared document. By tomorrow there are a number of things I need you to do. First, bring in your tissue samples that you will use with your lab. Second, know how to figure out molarity so we can create our solutions. Lastly, I want you to start the process of knowing the content in 1.5 and 1.6, the final chapters in this unit. Some of the finer points you should know (although you should know it all) are Pasteur's and Redi's experiments, cyclins and how they were discovered, and what a mitotic index is used for, but we'll get to these later in the week.
Honors Biology - Today we started our day by reviewing your homework which was the one pager on the microorganism. Next, we updated out table of contents and reviewed our essential questions so we are reminded of what we know up to this point. We then looked at the Petri Dishes we were growing from next week. The next thing we did was play a funky game: https://biomanbio.com/HTML5GamesandLabs/Cellgames/celldefensehtml5page.html The last thing you did was you created an accurate drawing of a cell membrane which included color, labels, and annotations. What didn't get finished in class can be finished at home.
IB Biology - Today we started on our lab by learning about molarity and creating solutions. Tomorrow we'll take initial mass and start the osmolarity lab for real. While the basic procedures should already be constructed by you and your group, I now need you to just hold on this for now and make sure you are prepared for 1.5 and 1.6 quiz. One of the last topics you need to be familiar with is mitosis, cyclins, and controls in the process. Do you know how these are connected to cancer? Do you know what an oncogene or a carcinogen is? You should know what a tumor actually is? What does metastasis mean? Be sure to do the work on the DBQ on page 59.
Honors Biology - Today we reviewed microorganisms through the one pagers you turned in. Then we started a new entry titled Microscopy, a way to see cells and their membranes. Then I showed you how to use cells and we made a quick sketch of a microscope on the right hand page, annotating and labeling as we went. We also discussed whether we would see cells, bacteria, and viruses. Lastly, we discussed how to make slides and when, and why, we use stains. Then you got to look at a hair under the microscope to start your practice. Tomorrow we will be looking at cells so come prepared with some type of tissue to view. Some tissues that work really well are onion, bananas, fruits and roots in general, but remember that you only need TINY amounts. Please don't bring whole fruits, etc.
IB Biology - Today we spent part of our time talking about the material from 1.5 and 1.6. We also discussed what would be on the quiz, but I think we'll push that quiz until next week. Tomorrow you will be placing your 5 samples in each solution once you have weighed an initial mass for each piece. This means that you will have 5 samples in EACH solution for a total of 60 pieces (30 potato and 30 other). Make them small, but unique when you cut them. If you think about it, putting 5 cubes in a beaker that are all the same size could be confusing. If you cut the cubes a bit different in shape and size it should be easier to figure out. So, long story short, take this additional time that I am giving you to prepare more questions for me about cells and I'll do my best to answer them. Next week will be the big unit exam, but not before we take a quiz on the last two sections.
Honors Biology - Today we started by discussing the recent Ebola outbreak in DRC. It was interesting to see how cultural influences can really cause problems for people trying to help. IN addition, we discussed how Ebola actually attacks your cells/body, which is our whole focus right now! Next we reviewed how to use the microscope from yesterday and created illustrations of three kinds of cells (aquatic plant, human cheek, and your tissue). I felt a little rushed today so we'll review tomorrow and maybe have a bit more time to use the scopes. BUT don't forget that we are doing all of this because we are learning about cell structure and how this is related to you getting sick. Tonight, below the drawing you made of the CELL MEMBRANE a few nights ago(It's on the left side of entry 9 for me), I want you to speculate on how you would attack a cell if you were a virus of bacteria. This is should be a labeled illustration with a couple of sentences explaining, and should use the proper vocabulary (protein channel, phospholipid, protein pump, passive transport, etc.). You don't have to be a genius, just look at the structures of the membrane and think about what could cause problems.
IB Biology - Today was fundamentally a day of lab work! You set up your work and on Monday we will recover the samples and take final mass measurements. You already know that we have pushed back the quiz and final unit exam so please make sure not to forget and prep for that quiz. On Tuesday we'll take the quiz and prep for our unit exam which will be on Wednesday.
IB TOK Opportunity from Mr. Davis: Please review the following as we have a doctoral student who will be Skyping in to discuss this topic with you:
How far should humans go in editing life from its genome with different techniques such as CRISPR/CAS if this could mean changing the ontology of the being (plant, animal, human) that we are modifying? You must argue this not only from the scientific evidence but from at least two of the four ethical theories we have studied (Virtue Theory, Natural Law, Utilitarianism and Kantian Ethics).
Honors Biology - Today we continued looking through the microscope and we even found some protists swimming around! But really our main focus has been looking at the differences in structure between plant and animal cells. So, you should have made a CAREFUL illustration of each type of cell, CAREFULLY labeled them with the cell parts that are visible, and then CAREFULLY annotated those labels with the function of this part. But what are the differences? Be sure to list the obvious differences under your drawings.
Now, Someone asked a really good question today, "Can plants get diseases too?" and the answer is Yes, but not exactly the same kinds. We'll attack that next week.
Lastly, You received an article. You will notice that I set it up so that it is Cornell Note style. In the Q column (the blank on the paper to the left), please be sure to use the reading strategy Read and Recall (this is on your reading reference sheet). Note, that this reading strategy asks you to make level 2 and level 3 questions. If you look in the front of your notebook you will see Costas' questions. Use these word to make your questions. Yup, just grab a level 2 or level 3 word and use it to make your question. This article will be turned in on Monday, but if you lost it, you can find it below.
IB Biology - Today we finished the few cellular structure lab interviews. Once we completed that work we looked at a couple of videos and started the process of brain storming on what we need t understand what we were seeing. In class we made a big list of the observation and needs in the form of questions. What it really comes down to is understanding how cellular membranes function and facilitate cellular processes, which is our focus this week on 1.3 and 1.4. So as you read 1.3 tonight, try to see if any of the material you take notes on start to answer these questions. Here are the videos again for your review: https://www.youtube.com/watch?v=PPCzvWgqyUI and https://www.youtube.com/watch?v=OYoaLzobQmk
Honors Biology - Today we continued to work on our measurement lab. On Wednesday we will take a quiz on this material so make sure you complete everything. By the end of today, you should have completed 5 stations. If you haven't, you should probably come in at lunch to make up your work.
Tonight for homework I need you to watch the Watch this Amazing Randi who debunked psychic on his television show: https://www.youtube.com/watch?v=joADD7jWqa4 During the 16 minutes video you will see several samples from his show. Document each of the psychic "acts", and how Randi debunked (proved it was fake) it on the right side of a new entry. Lastly, on the left side of the entry, name any current events/trends that you believe are not scientific? Make a citation of where I can find it, and then how might we be able to debunk these current events. This is NOT due until Wednesday.
IB Biology - Today we spent the majority of the time connecting the material from 1.3 with the dynamics we viewed in the videos from yesterday. We realize that there is a lot found in a cell's membrane such as cholesterol, integral proteins, protein channels such as aquaporins for passive transport, and that the proteins that we call active (sometimes called protein pumps) use ATP to power them, but when we say power them, we really also mean that he protein changes shape facilitating work to be done. We know a lot, but this lead to other questions like, "how do cells cling to each other?" or "How do they communicate?" or just "How do they do their job when they are deep within a tissue?" Tonight what I need you to do is to to give me a DETAILED idea of a day in the life of a cell. You may pick any cell to do. Find out how it works in doing it's job and then answer the question in detail about how it communicates, how it transport it's product to the body, how it hangs on to the other cells in the tissue, and how it might defend itself. Remember that our whole function is to examine the role of how the membrane facilitates these activities, but also what it is that the organelles do.
Lastly, I want you to come prepared to discuss Davson-Danelli model vs. Singer-Nicholson -.Fluid Mosaic model. This means that you should know what they are, how were the models discovered, and why each model might provide insight to cells.
Honors Biology - Today was your very last day of working on the measurement lab stations. You had enough time to get them done and tomorrow you will take a quiz on the concepts, and you will also input some of your data, so make sure your work is all correct. Tonight you should complete the homework that was assigned yesterday. If you don't remember what to do and how to do it, just look above.
IB Biology - Okay, so today we were able to start looking at how membranes interact with each other; how they cling, spacing, how endocytosis is triggered, and how materials can make their way from one side of a cell to the other. Tonight I want you to review 1.4 and to come prepared with any questions that still linger. I also need you to complete the TOK question in the book on page 36 as well as the DBQ found on the same page. Oh, and here's the game we played in the beginning of class: https://biomanbio.com/HTML5GamesandLabs/Cellgames/celldefensehtml5page.html
Honors Biology - Today we took an exciting quiz on the work you did for your measurement lab. If you didn't do great on this quiz you can always see me for some help and you can bring that grade up to a C!!! Yippee! Later in the day we discussed the idea that we haven't learned any biology so far! YOu're right, but today we start! You streaked some Petri dishes with swabs from various objects. I'm now incubating these and we will periodically check them to see if anything grows. We did this because our first unit deals with health and NO ONE in any of my classes could tell me what happens when you get sick. ...I didn't think you would know, many people don't know. So, to prepare for tomorrow I want you to start a new entry called, "Things in the Microscopic world" On the right side I want you to list 6 things that are living that we can only see with a microscope. These drawings should be evenly spaced out on the right page. You might include bacteria, viruses, and other itty-bitty things. Would fungi be there too? I wonder if all single celled organisms are bacteria? IS a virus really living (include virus even though it isn't)? Dig around and get your drawings down!
IB Biology - Today we got a good chance to discuss and review 1.3 and 1.4 and more specifically the TOK and DBQ questions on page 36. If you find these confusing lie some of you did, keep plugging, today felt very successful! Tonight I need you to be prepared for the quiz on these chapters, but I really want you to know about he action of sodium-potassium pumps in nerve cells. Please illustrate this cell, and the process, but then explain with diagrams how nerve toxins interfere with this process. Here's something that will help: https://res.mdpi.com/toxins/toxins-02-02359/article_deploy/html/images/toxins-02-02359-g007.png In addition, and in preperation for our upcoming lab, be sure you study the DBQ on page 42. There is a chance there could be a question on the quiz. I wonder why they would use percent mass change instead of another unit of measurement? ...You should have an answer.
Honors Biology - Today we took a good look at the size of things. We learned that the mm, micrometer, and nanometer are necessary to understanding the sizes of things. You may ask why do we need these? ...and that's a good question, but know that we are trying to figure out how to microscopic thing interact to cause disease in our bodies! This is the first step to understanding the structure of these tiny things! Tonight, on the left side of the entry that we worked on today, I need you to create a detailed drawing of a generic, non-specialized, animal cell. Here's a very simple picture you can copy, but you can use others as well. http://www.enchantedlearning.com/subjects/animals/cell/
Please make sure that you illustrate properly which means to use a ruler to attach labels to organelles/parts. Give 7 words of less to describe function and this should be next to the label. Use color to differentiate the organelles as well. MAKE IT NEAT!
IB Biology - Today we worked on reviewing everything from our latest 2 units, 1.3 and 1.4. Next we took a quiz after the review, and then discussed the introductory formal lab that deals with the concept of osmolarity. I've posted a sample lab so you can get an idea of what it might look like, check it out. Lastly, before we get to next week I want you to watch the video that deals with a statistical test called the Student T-Test. The only thing I want you to come prepared with is the answer to, "When would I use the Student T-Test?" Here's the link:https://www.youtube.com/watch?v=AGh66ZPpOSQ&feature=em-uploademail
Honors Biology - Today we came back together and had a chance to really differentiate between the various microorganisms that might be considered pathogens (Disease causes). Now we know that their sizes and also their structures. But our original questions still remains, How do viruses and bacteria make us sick? Which is what we titled the right hand side of a new entry. Then, after looking at the powerpoint that I attached below, we tried to get some essential questions that relate to what we REALLY need to know to answer this question. The most important first step is How do these cells/viruses come into contact with each other? Which means we first need to look at membranes! By Wednesday of next week I want you to specialize in any type of pathogen you like and to create a one pager. The powerpoint is below and towards the end all of the criteria for this project, and additional resources are listed. This is due next WEDNESDAY!
IB Biology - Today we started by taking a deep look at your homework on the origins of cells. I'm disappointed in our inability to have a discussion on this topic, and that's a function of writing stuff down that you don't really understand. Tonight is the only night you get to do a redo. You can resubmit this tomorrow.
In addition to redoing last night's homework so that you understand it, there are other tasks that must be done as well.
1) You need to start the process of reading and digesting chapter 1.1. This should be completed tonight.
2) Research what stem cells are. Find out all of the sources of stem cell harvesting (please make sure this is recent), describe a minimum of 3 ways stem cells are used, and finally describe three ethical issues on using stem cells AND YOUR STANCE ON THESE ISSUES! This too should be completed by Wednesday
3) Describe the differences between light microscopes and electron microscopes, and include the limitations of each type of scope. This is due by Wednesday as well.
Honors Biology - Today we set up our notebooks! We used our notebook and all of the inserts were placed inside. This included a contact page, table of contents, word roots, reading strategies, processing tasks, the work you have completed so far, and parent input pages at the end. Tonight I only need you to create a cover for your notebook. To do this, go back to the "about" page on this website and make 6 drawings, using a minimum of 4 colors, then include your name and the title, "Biology". Yes, the illustrations should be based on what we will be learning. This should be attached to the front cover using some tape.
Oh, I almost forgot, you also turned in your data collection and analysis work. I'm sorry to say that very few of you completed it, and that will hurt your grade. Let's get back on the wagon and get this simple homework assignment done!
IB Biology - Today we went over the Origin of cells and the level of conversation that we had is where you should be after every reading. Tomorrow you have a stem cell discussion due and a comparison of microscopes. 1.1 is also already done as well, but can you explain why cells are so limited in their size? You should. Be ready for it! In addition, I need you to read and take notes on 1.2 in your books. Please also come prepared with questions on the materials. You can use the Costa's Levels of Questioning from your notebooks to help you develop good questions. KNOW THE MATERIAL!
Honors Biology - Today we got a chance to share your artistic talent. Please make sure that you put some packing tape over the cover to protect it! I forgot to check them off, so I will do that tomorrow.
Then we created a new entry and used our final processed data from the jump lab and were introduced to the use of the Claim, Evidence, and Reasoning (CER) format of responding to data in a written format.
Next, we reviewed the nature of science that we've been discussing all along. We glued this sheet in on the right hand side of a new entry. On the left I want you to do your homework.
Your homework is to watch an episode of House, M.D., any episode. Once you have watched it, give me a brief summary of the show (1 paragraph) and then whether or not House 1) reported like a scientist (used CER), and 2) Performed science to help his patient recover (Nature of Science). This should be another paragraph. 2 paragraphs total.
Here's a link to an episode of House, M.D.: https://vimeo.com/4614191 OR https://www.dailymotion.com/video/x5j0yr8
IB Biology - Today we got into the nitty-gritty of stem cells and beyond. If you were able to follow the discussion and contribute, you are in the right place. As I look at the work that you have put together I am going to make an overall suggestion to use cornell notes for future notes. I won't demand it, but think about how easy it is to add notes during a discussion! So, for tomorrow, make sure you know chapter 1.2 if you didn't already turn it in to me, Go to page 25 in the book and complete the activity on identifying structures in cell micrographs. Next, reread page 11 and give me a response to the TOK question on that page. Lastly, prepare any questions you might have on this material as you will have a quiz on Friday.
Honors Biology - Today we discussed the House MD episode you watched last night. Did he do CER? Did he demonstrate the Nature of Science? You may not have recognized it right away, but he did do those things. Then we got into groups and played a matching game of IB Command Terms. I gave you the handouts (below) and you glued them on the right side of your next entry. Last I want you to take the words that you misidentified, write them on the left side of the same entry, and then write a sentence using either "unicorn" or "purple dinosaur" that shows me you understand the concept you missed.
IB Biology - Today was a pretty productive day in that you were able to work on your presentation that is due tomorrow as well as reviewing all of the material for your quiz on 1.1 and 1.2. Tonight I want you to prepare for your quiz by reflecting on your notes. This means going to the end of your notes and seeing if you can summarize the major points of these notes within 5 sentences or through the use of illustrations.
Honors Biology - Today we began our last skill based lab, learning to measure and calculate. Since the metric system is really the most important thing we need to know for this lab, I have posted an optional homework assignment. You DON'T have to do this, but if it come in tomorrow I it will make up for any assignment you may have missed in the last two weeks. Check out this web article: https://www.theatlantic.com/education/archive/2016/06/why-the-metric-system-hasnt-failed-in-the-us/487040/ Now, using the reading strategy "One Page Summary" from your reference sheets in your notebook, give me a "one page summary" (use the guidelines) of the article.
IB Biology - So today we did three things. First we set up for our presentation on cells. Next we took the quiz, which, by the way, I had to modify to account for socrative's shortcomings on calculating partially right answers. Lastly, you played this game biomanbio.com/HTML5GamesandLabs/Cellgames/cellexplorerpagehtml5.html And I came to speak with each of you. If you did not get interviewed by me, you will on Monday. This weekend, take a break, but if you want to get ahead, check out 1.3 and 1.4 in the text. It's all about membranes!
Honors Biology - Today, for those of you who actually got to work, we worked on the measurement lab. Next Wednesday you will be taking a quiz on this material so make sure you are doing well and asking questions. This weekend, for your entertainment (this is not required), watch this: https://www.youtube.com/watch?v=Rrza1mS1ng8 and let me know which one you think is the most interesting (AND WHY) on Monday. ...make sure you know why!
