classwork/Homework
Monday IB Biology - Today we did a lot of things! Number one, we reviewed your alien argument and your chlorophyll graphs. Please redo those before Thursday and you can get full credit. While we did this individual conferencing, everyone else was working on their photosynthesis/cellular respiration lab. This lab will be due by next Monday and should be formally written with an emphasis on the data analysis. My last point is that the Photo/CellResp exam is on Friday. This is the LAST OF THE BIOCHEMISTRY!!!!! See me if you need help, but I've also posted powerpoints on photosynthesis and CR below. Also, don't forget the videos and animations from last week. Honors Biology - Today we started the process of discussing the major ethical issue of, "if we can manipulate DNA, should we? " We discussed some frameworks for making guidelines and then decided on three simple statements. You then got assigned one of the following articles an responded to it using the questions below. Each article title is a link to the article. 10.1 The Biotech death of Jesse Gelsinger 10.2 The Eugenics Movement 10.3 The Ashanti DeSilva case 10.4 DTC (Direct to Consumer) genetic testing 10.5 Gene therapy against brain cancer 10.6 Making insulin 10.7 Amniocentesis Questions to answer on the left. What is the Genetic Engineering Technology presented in your article? How does it work? How does your technology address the respect for a person? What are the potential benefits of using this technology? What are the potential risks associated with using this technology? How effective is your technology? What would be fair uses of your GET? How can we distribute resources so that each person has access to the benefits of this technology? Tuesday IB Biology - Today you got super busy on your labs. Good, but please don't forget that the presentation of this work is just as important as the lab work itself so please work on your title, introduction, hypothesis, procedures, materials, etc. Data analysis comes later, but make sure you have enough data. This is VITAL to doing well. Remember that our whole focus is on this analysis section. I have placed an example lab of milk spoilage at the bottom of this page so you can get a sense of what is acceptable for each section. Lastly, don't forget to clean up your alien arguments and graphs for max credit! Those should come in by Thursday. Honors Biology - Today we started by jigsawing all of the articles we read last night. I do realize that some were out of date, but all of these were from science journals. I know it's harder reading, but you should get used to it and I'm glad to see many of you did well. Then we shifted gears and started to talk about the pros and cons of some of these therapies that are meant to genetically help patients. The last thing we did was speculate on the idea of "is there really anything that can pinpoint specific DNA." and what must be some of the barriers to that. Tonight, using the nature of science and validity concepts, you should research what genetic therapies are being applied to your case study condition. So look up reputable/verifiable/evidence based treatments and get the DATA (numbers) down as well as how the therapy works. This goes on the left side of the entry we started today. Wednesday IB Biology - Today you continued to work hard on your labs, but don't forget that some of you have a graph and an alien argument to turn in tomorrow. Below I have posted a format that could be really helpful to you doing your lab report. Hey, and please remember that even if this lab doesn't come out as expected, this still is data that we can learn from. Honors Biology - Today we came back together after looking at our research and try to find any therapies that specifically target DNA. At least in one class, someone found that there is something with wild possibilities called CRISPR/Cas9. Then we watched a video on the potential of of this technology and took notes on the main points. Here's the video. https://www.youtube.com/watch?v=jAhjPd4uNFY Here are 2 other videos on CRISPR if you are still struggling with how it works. Video: What is CRISPR? Video: Doudna TED Talk Your homework: CRISPR/Cas9 Article -Read and recreate a diagram in your own words on the left side of the entry we started. This is what is due tomorrow. Yes, use color! https://docs.google.com/document/d/1EgifpmXiUcc8k_9x16pFFDW65mju66HpIe5RvAV-enw/edit Now that you have completed your diagram, please create a couple (2) of questions or comments you have about CRISPR. Thursday IB Biology - Today we reviewed for the exam tomorrow. Realistically if you know the alien argument really well you will be fairly well prepared. Ultimately you need to know the when, where, and how of cellular respiration and photosynthesis. Please see me in the morning if you have any issues. Also, don't forget to follow review the animations and videos I posted last week. Honors Biology - Today we started the day by reviewing what CRISPR is and how it works. Next we looked at our personal ethics toward the use of this technology. We then watched the following video: https://www.youtube.com/watch?v=ZRz0xEGaCSw and analyzed the event, but also the reasons why the personal reaction were the way they were. Finally we reexamined our beliefs after our classroom discussion. Tonight you need to do research and find out if there is any research going on related to CRISPR and your case study. Friday IB Biology - Today you took your unit exam on PS/CR. Hopefully you did well! On Monday, you and your partner should submit your write up from your plant experimentation. Also,as we transition to your final, which is you IA, I want you to come prepared with at least a few ideas in biology that you are really interested in. They do NOT have to be about biochemistry, they can be about anything related to biology, but of course the better it can be isolated to a single dependent and independent variable the easier it makes things. ...and of course it's usually biochemical processes that are easy to deal with that way. Honors Biology - Today we started by closing out the ideas for how CRISPR works and then watched the original video on DMD kids. This allowed us to review the whole unit and all of the things we can answer about DMD now. Lastly, we know that we are going to start our unit assessment next week so I want to see you transfer all of this knowledge you have by applying it to your case study. We will have time in class, but come prepared with some answers to the following questions: 1) What is the background of your case? What is the condition, when does it occur, what are the symptoms, etc.? 2) How is DNA involved with this case, and if DNA code for proteins, how are proteins involved? 3)What role does mitosis and meiosis play in the case? 4) How/where/when did the error in the DNA occur? Meiosis (crossover, nondisjunction), etc. 5) Can you use statistics to describe your case? Make a Punnett square, create/use a fictional pedigree, or describe why these tools can't be used. 6) What are some ethical concerns about the current treatment of this condition, and future applications of CRISPR? 7) Create a personal reflection on genetics, how genes are passed on, on the future of genetics, on the future of genetic treatment of your case, ethics in treating genetic disorders. This does have room for your personal feelings, but be sure you have clear reasoning! Bring it all together!
