Monday - First thing I need to do this week is apologize for being out again. My wife has some potential nerve damage and she has to be tested on Monday. The doctors have to put her under anesthetic so she needs me to drive her and get her home safe. Please make life easy on the sub.
IB Biology - Dear IB students, I want to let you know that I had planned on talking to you today about what all of our assessments mean to both you and me. To talk about how we are not focusing on grades but learning, and how our assessments guide us so we can learn better and therefore get better grades. This will all have to wait until tomorrow. The good thing is that I am able to come in early this morning and leave what you will need to complete your work today! Aren't you happy?!
So I hope you brought in some tissues to examine, but if not I have left you an onion, a banana, some elodea(a plant), and wood scrapers to scrape for cheek cells. Using the IB guidelines for making illustrations I want you to work in groups and to use what we were studying last week, cells and structure, to make some connections through observations. Recognizing that some of these tissues are plants samples and will have structures different from animal cells, and using the microscopes and slides provided, view the tissues and make scale drawings of the cells and the structures you view (look carefully). Our goal is to get a cheek cell, onion cell (or banana), and elodea cell all drawn and labeled. You have already completed some prep work on this, but you can see the tips again for this on pages 4-6 including what to stain each example. BTW Elodea only needs to have one leaf plucked from it and NO stain applied. It's alive so look for movement in the cell.
Criteria for Biology Core Drawings with Annotations
Biology - Hello you guys! Sorry I'm not in today. I will try to be in about every day I can this year, but this was an emergency. SO while I had planned on showing you some cool polymer demos, I need to wait until I get back on Tuesday.
Instead of what I had planned we'll just get a jump start on a related topic that we are going to deal with later the Cycling of Elements on our Planet. So what I want you to do is go to a new entry in your notebook and use that as a title on the right page.
On the right hand side of this new entry, I want you to write that we know that the majority of the molecules that make us up are CHNOPS. For us to get these we eat, drink, and breathe, but where do we see these various these elements on our planet? Write this down too. This is your essential question.
Still on the right hand side of this entry I want you to create three categories: Land, Ocean, and Air. Next to each category I want you to do some research and find out which elements can be found in these regions and in what forms. When you are done you will have many forms and molecules listed on the right. Ex. Ocean: Hydrogen and Oxygen = Water (H2O), Oxygen O2, Sulfur ...etc. Remember we need to which of the five are found in each region and in what forms.
As homework on the left hand page of this same entry I want you to make an illustration of any one molecule (try H2O or CO2) and how it cycles from water to land to air and back again. You can find many online to copy, but be sure to use at least 4 colors and you must take care in constructing the illustration.
Honors Biology - SO taking the test on Friday was a big ugly mess! I'm not sure what happened to the other sheets, but we certainly came up short! Because of this we are going to do a redo!!! It doesn't happen often, but it is this time.
The sub will be passing out a new sheet of organic molecules to you today. Once you have these you will move to the positions we had on Friday (seats 2 and 4 of each row must work at the station). You will then circle every molecule with one of four colors to identify which group each molecule belongs in. Once you have completed that, on the back, please complete your test by providing your reasoning. In other words, explain what qualities each molecule had that made you place them into these four groups.
Remember: Your Claim is the group you placed them in by coloring them. Your Evidence is the actual illustrations, and your Reasoning is the explanation that you put on the back. This is worth three points to your grade. A maximum score of 3 will have solid reasoning and your molecules will be grouped properly.
If you are done before everyone else, please be sure to do a quiet activity until everyone is done. I should be back tomorrow. I have some cool demos for you on Tuesday!!!
Lastly, for homework, as a refresher on what we started this school year with on the nature of science I want you to watch an episode of House MD, any one you like, and watch it. First describe the basic plot, next describe three things that he (House, MD) did that were good science practices, use our list in your notebook and cite the number. This is on a SEPARATE sheet of paper that will be turned into me for 3 points on WEDNESDAY (Yes, 2 days to finish it)!!! You will make your CLAIM by listing the number and practices he used. You will have EVIDENCE from the plot you described, and will explain how the two match for your REASONING. 3 points, due Wednesday.
Here's an episode online if you need it: https://vimeo.com/98343184
IB Biology - So today we finally had the conversation about what assessments mean to me and what they mean to you. Hopefully this will help us to be continually successful. Then we continued our exploration of cells using the microscopes. I'm going to give you a little more time tomorrow to put the final touches on these drawings. As homework I would like you to finish the illustrations as much as possible, start the notes for section 1.4 using the topics listed below, and then ON THE LEFT SIDE of your 1.4 notes complete a response to the TOK question found on page 36.
Your list of topics for 1.4 are:
simple and facilitated diffusion,
structure and function of channels,
The basic idea behind osmolarity and how to estimate it,
Structure and function of pump proteins
transport using vesicles: endocytosis and exocytosis
Why we should prevent osmosis in organ donors
But this is not due until Thursday
Biology - Today you got to see some cool demos related to bonding and polymers so we can learn how these processes create cycles in the body as well as in the world. Tonight I want you to start your research on the molecule/element you have been assigned by your group and should include cycling from land, sea, and air as well as from organic to inorganic sources. What you do for your group will be placed on an integrated poster by Friday at the latest. This research should be added to the entry you started yesterday. Your research should also include
Honors Biology - So today we had a chance to finish up our lecture on bonds and polymers. We had a couple of demos of polymers to illustrate the idea of how molecules bond in long strands and sheets to make polymers. Tonight though I want you to finish watching the episode you chose of House, MD and the do the analysis I ask for yesterday (Look back at yesterday's instructions. This analysis is due tomorrow and will be handed in on a separate sheet.
IB Biology - So today we had a chance to discuss the TOK question from yesterday. After that discussion you then had time to do the following three things: 1) Finish your cell illustrations, 2) Start working with partners on the DBQ on page 42, or 3) complete your notes on 1.4. Tomorrow you will have an opportunity to ask questions on any of this material in preparation for your next content quiz on Friday.
Biology - Today you had a chance to collaborate with your team mates on your project for the cycling of elements on the Earth. As you put this poster project together you also need to be aware that the requirements: 1) Tell the “story”. How does your element cycle through the hydrosphere/geosphere/atmosphere?
2) Make a picture and explain each connection and “stop” on the diagram.
3) Color code the arrows that show your element passing from organic sources to inorganic sources.
4) Color code all of the man-made influences to these cycles?
As homework tonight I want you to be prepared for the small activity tomorrow about the relationship between the following terms: Organic, monomer, polymer, amino acid, sugar, fatty acid, carbohydrate, lipid, protein, and nucleic acid.
Honors Biology - Today we started to look at how the elements that form us cycle through our world. Then in class you had an opportunity to work on a specific cycle. Eventually this will be in one big poster, but for now make sure you are an expert in your particular area. On another note, tomorrow you will have a small activity worth points to your grade on understanding the following terms: Organic, monomer, polymer, amino acid, sugar, fatty acid, carbohydrate, lipid, protein, and nucleic acid.
IB Biology - So today was a minimum day and that's always hard for getting things done, but we did have a chance to go over the DBQ from yesterday as well as answer any questions you may have had about the content from chapters 1.3 and 1.4. Tomorrow we will take the quiz on these chapters so make sure you really spend the time on this information. Of course you can ask me some last minute questions tomorrow.
Biology - Today we took some time to do the vocabulary activity and hopefully you scored big since we took so much time yesterday going over it. Tonight I want you to be sure to spend your time really focusing on doing a good job on your cycling poster project. This means that you have all of the criteria we set out yesterday for your project: See Tuesday for the details of what you need.
Honors Biology - Being a minimum day we didn't get a ton done today but we got your vocabulary activity done! Tomorrow you will be placing your work for the element cycling project on a poster and the last thing I need you to do is to find at least one human health related issue to your cycle, or rather the disruption of the cycle. In other words what happens if you can't get the elements that you need.
IB Biology - Today in biology you started out by taking your quiz on membranes and transport within the cell (1.3 and 1.4). After that we prepared ourselves for the lab that we will begin next week on osmosis using sucrose solutions of various molarities. This weekend I want you to set up the framework for reporting your data: The first section will be called Design and will include: The Title, Introduction, Defining the Question, Hypothesis, Selecting Variables, Controlling Variables, Materials, and Procedures. The second section is Data Collection and Processing which includes: Results, Raw Data Collection (quantitative data and qualitative data), and Processing Raw Data. The third and final section is the Conclusion and Evaluation and will include: the Conclusion, Evaluation of Procedure, Improvements to the Investigation. We started the experimental design today and we'll add details to each of these sections and subsections as we complete them.
Biology - Today you had an opportunity to start your element cycling poster. You should have included your cycle from geosphere to hydrosphere to atmosphere and back again, the transfers of this element from organic to inorganic sources, how it get's into the human body, and man-made influences. This weekend you actually don't have ANY homework.
Honors Biology - You began your element cycling projects today and while your project is similar to regular biology (see above) I want you to include the health issues related to deficiencies in these cycles. Yes, you are doing your own work, but it's all on the same poster so be sure you included your name on your section. For homework you don't need to do anything! Relax and be ready for action on Monday!
