classwork/Homework
Monday IB Biology - Today we reviewed the many questions about DNA/RNA structure. You should have a fairly good idea of DNA/RNA's composition and structure, as well as its properties. Tonight I want you to review Chargaff's data by completing the DBQ on page 107. Use COMPLETE and DETAILED sentences for your responses making sure to address the command terms in the question. Please complete this on a separate sheet of paper so it can be turned in. Honors Biology - Before we started our new unit we updated our table of contents, and then boxed our first set of notes in a color and labeled them, "the crawl." To start our new unit you had an opportunity to view a new phenomenon (I have placed a copy below.) We then came to many logical conclusions about what we had seen. After discussing and listing those that we were most sure of, we then discussed what it is we would need to know to find out what is wrong with these subjects and then posted these on the board. Tonight I want you to start to think about these subjects and I want you to identify which body systems are affected and what would be your top 3 choices as to what happened to these kids. Your body systems ideas and top three choices will be written on a SEPARATE SHEET of paper (not in your notebook). Let me remind you to write in complete sentences, and know that you will not receive credit unless you also have an explanation of why you think the conditions you've chosen are possible. HEY, I need to clarify something I said in class today. While debriefing the test I said that the best explanation would be low blood sugar, BUT I was referring to the Crawlers, NOT to the rower. For the rower (the test) you only needed to explain how these were all related to his experience. So, don't freak if you didn't get into detail about blood sugar regulation! Tuesday IB Biology - I blew it yesterday and today! I was suppose to remind you about your PET. Are you still growing it? are you still measuring it? You should take a picture of it again as you will need that to show it's development. Be sure you are getting all of the measurements. Beyond your pet (like there's anything more important?), I need you to start to prepare for the unit exam. I have provided an outline of every Understanding, Application, and Skill listed for the chapters we have covered. Please use it tonight to take inventory on yourself. Which pieces are solid in your mind, which are not so strong. Tomorrow we will review all of these for you, but come prepared otherwise I don't really have any sympathy for you. The big test is on Thursday and Friday. Honors Biology - Today we started by looking at your ideas about what is wrong with our disabled kids, and then went back to our ideas from yesterday in order to establish some questions about what we are going to pursue. You set up a new entry on How Muscles Work and watched the following video to take notes: https://www.youtube.com/watch?v=94Q-fvCAJzQ Tonight I want you to add to your notes by drawing a healthy bicep muscle including tendons. Also show the muscle's layers: fascicle, muscle fiber, myofibrils, and actin and myosin) like you saw in the video. I've also placed an image that should really help as well on the bottom of this page. Now, On the left hand side of your entry from today, I want you to draw that same picture from the right hand side, but with the addition of what must be different in these disabled boys. The difference could be on the very tiny scale or an overall problem, but be sure to draw in detail and explain what you drew! ...Yes, color is always necessary for credit. Wednesday IB Biology - Today we spent time answering all of your questions on the test. You can still come see me at any time before the test to get help, but you should be fairly solid to take the test tomorrow. BUT don't forget that you have a number of flashcards that you could also be using as a review, and of course your book. Please review everything as there are no retakes. Honors Biology - Today was an amazing brain storming session that I didn't really expect to happen the way it did. You have now isolated that the condition these kids have in a muscular dystrophy of some sort and that it is genetically related. WOW! I am super impressed. Tonight I want you to read the following article and we'll see if you are right. For this article I want you to use the reading strategy of "Sum It Up" on the right hand side of a new entry. On the left hand side please be sure to recreate the lower diagram from the article. We will use this tomorrow so don't use more than 1/2 of a page. The article can be found below. Oh, and if you want to learn some more about the muscles in your body, play this game and let me know how well you did: http://www.anatomyarcade.com/games/PAM/PAM.html Thursday IB Biology - Today we took the first part of your unit exam and tomorrow you will take the second part. The second part is very much like paper 3 on the IB exam so it will be composed of a number of graphs that will need to be interpreted. Please be sure that you look over the following website for guidance on reading graphs. Oh, and yes, the content is still on your knowledge of macromolecules. https://www.thinkib.net/biology/page/19051/describing-trends-in-ib-graphs Honors Biology - Today you guys were able to describe actin, myosin, titin, and dystrophin from your readings. These are all very important proteins to muscle tissue, but what exactly is this "protein" thing and how does it fit into the big picture of what we are made of? This is why we went to the idea of looking at macromolecules. So I gave you that sheet today (attached below) and then gave you important information on the function of each of these. Tonight I want you to read the following article on why muscles don't work as well in DMD patients. (found below) Once you read the article I want you to submit your responses to the article on the following google form: https://forms.gle/y4dtE3mgnxmeNvKT9 Nothing needs to be written in your notebook unless you would like to add some "tasty tidbits" to your notes. Friday IB Biology - Today you did part two of our unit exam. I hope you feel like you did well. WHile we will start a new course of study going into details about protein synthesis on Monday, this weekend I'm not assigning homework. If you chose to work as an individual on redoing any part of your lab, this is the time to do it. If you return your new revised copy along with the original paper, you will be eligible to raise your grade. Please consider doing this as this may be the only time you are allowed to do this. Honors Biology - So today we spent a chunk of our time digging into the idea of WHY. Why do people with DMD have this problem with their muscles. You learned about dystrophins role in the cell and what it means to have Creatine Kinases (CK) in your blood. This weekend I want you finish watching the video (5min) and taking notes on the right side of our entry. On the left I want you to come up with a visual analogy for dystrophin and it's role within cells. An example of this would be looking at dystrophin being like and anchor on a boat. ....BUT you need to come up with something different than an anchor and boat. Yes, you should use neat lines, labels, and of course, COLOR. A brief explanation (3-4 sentences) should be below your picture should describe why your visual analogy is a an accurate one. You will be sharing these on Monday. Video on DMD: https://www.youtube.com/watch?v=Ebu8W8Osuxk
