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. All I really want you to see is the different components/atoms that make these things up. They don't have to be super complex. 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. You can just search, "Sources of ________" and you should know what foods contain them.
IB Biology - Today we reflected on some review questions from Chapters 1 and 2. Next, you had your last day to work on your video. Once you have finished your video and emailed that to firstname.lastname@example.org, you should have downloaded the powerpoint on DNA replication, reviewed the work, and then written questions you have about the material so you can look for your answers in the videos your classmates have created. Remember that tomorrow you will be having a guest speaker and will meet in the little theater instead of 187. See you then.
Honors Biology - Today we first reviewed the ideas from yesterday, which was "why do we need to know stuff about proteins and macromolecules?" Next we reviewed what we know about DMD and muscles. Lastly we made some connections between muscles, fascicles, myofibril, and fibers, and then then added skeleton, tendon, actin, myosin, and dystrophin to the mix. The last thing we did was look at some statistics on proteins found (or not) in muscles. Turns out that people with DMD have higher levels of creatine kinase and lower levels of dystrophin. It seems that actin and myosin is about the same! Tonight, on the left side of the entry we started today, I want you to find out the roles that creatine kinase and dystrophin play in muscle tissue. To do this you need to watch the following video: https://www.youtube.com/watch?v=Ebu8W8Osuxk
IB Biology - Today we had the great opportunity to hear from Dr. Byron Jones, and I learned that Kat Jones renamed herself "rainbow cuddles" (or something like that) when she was a little kid! Interesting! Your work for tonight is to go through chapter 7.1 and to identify those parts of the chapter you are struggling with so we can see some "informational" videos on the topic and straighten things out. Please come prepared.
Honors Biology - Today we had the great opportunity to hear from Dr. Byron Jones. If I didn't like you as much as I do I would probably go and become a pharmacist! I had an article planned for you tonight, but I think I'm actually going to save it for later. That means that you only need to come prepared with the video questions I had you respond to last night. Come prepared! Yes, you are welcome.
IB Biology - Well, today was interesting. You have read chapter 7.1 and took notes and wrote questions, and then you saw the videos created for it, and then you had a chance to have me answer your questions that still linger. This weekend I want you to distill your work on 7.1 and if you have ANY lingering questions, I want to attack them first thing on Monday. Second, I need you to preview 7.2. Be sure to look at the first panel in the chapter so you know what you should know, then read, then list any questions you might have about he material so we can start the process we just did with chapter 7.2.
BONUS, If you would like to earn an easy extra credit point towards homework you could also read the following and write an analysis of the moral implications of these finding.
https://www.sciencedaily.com/releases/2017/08/170816145357.htm If you just blast through this you probably won't get the point. Consider the impact of the past on the future, and our present and how it's been influenced by the past. Think about the "crimes of the father". And what about our current social climate?
Honors Biology - Today, after I showed you the 2020 travel trip, we talked about the role of creatine kinase, dystrophin, and calcium in DMD muscles. And we discussed the idea of how dystrophin acts like a boat anchor. Your job this weekend is to come up with a UNIQUE analogy (not my boat idea) to what dystophin, creatine kinase, and calcium do in a DMD muscle. This should be written on the bottom of the left hand page we made last night.
This page contains nearly everything that you need if you missed class.
