classwork/Homework
Monday
IB Biology - Animal Classification Yearbook project: Use the taxa listed below: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species. This work should be completed on the backside of criteria sheet I gave you today and should be completed by tomorrow. We'll be using these then. In addition, I want you to know that we will be taking a quiz on chapter 5 material on Wednesday (maybe Thursday), and Later this week we will be reviewing the Evaluation section of your IA, please do NOT slack! Honors Biology - So today we took some time to make sure we clarify what our understanding of natural selection and evolution are at this point in time. We then watched the ending of the Addie story. Lastly, we discussed your homework which was how do we/biologists define speciation (the point when 2 populations become distinctly different). We decided that the best definition of this is "When two populations from the same ancestor do not, or will not, reproduce with each other." This is a common, but not always perfect definition. We can work with it though. So how does it happen? Well, it happens due to isolation. There are three ways isolation happens between two populations: behaviorally, temporally, or geographically. Your job tonight is two parts: 1) Look up a definition for these three types of isolation and jot them down next to the note from today. 2) You will start a new entry titled, "Juncos of UCSD and Laguna Mountains, are they different species?" Underneath the title on the right side, please search for "Juncos of UCSD" and then "Juncos of the Laguna Mountains" and make detailed observations of the differences in their physical appearance (coloration, patterns, size, etc.) Tuesday IB Biology - SO today we got a chance to see your animals and spent a chunk of time trying to sort them out into the best "yearbook" pages we can. You probably realize that it was really quite difficult to make this happen. The taxa certainly helped, but Kate said at one point, just because they look similar does not mean they are related. Another way to organize organisms is to look at their common ancestry and that is what you have been doing for homework for the last few days. Tomorrow you will be coming in and constructing a cladogram for your organism along with others so you need to know how it works. This is why I want you to complete the DBQ on 273. This is due tomorrow on a separate piece of paper. If you don't get cladistics, you will struggle. HEY READ THIS!!! I would sign up as FAST as I can! Health Pathway students interested in CPR through the American Heart Association. They can book a slot in the class at website https://cprhealthpathwayclass.youcanbook.me Dates offered are Feb. 29th, March 14th, April 18th and May 16th. Two classes are offered per day: 8-12 and 12-4 at the Mollison Complex Room B 301 N. Mollison, El Cajon 92020 Honors Biology - Today we started by reviewing how speciation occurs through isolation. We then decided to start looking at the physical features of the juncos. I then gave each of your groups some data on wings, tails, and coloration and we speculated on if there were any answers as to why these differences existed and if these could conclusively tell us if the Juncos of UCSD and Mt. Laguna are truly different species. Tomight, using the bottom right side of your entry I want you to make another section titled "Behavioral Traits" and then find online research on junco behavior. It does not need to be specific to UCSD or Mt. Laguna. Wednesday IB Biology - SO today you were able to make a cladogram with your partners using the onezoom.org interactive. The trace function really helps. Period 1 I will need the finished products tomorrow. You will be having a quiz on chapter 5 information since we will be transitioning to ecology soon. Please make sure you go through all of the material as a refresher. After our quiz tomorrow, we'll be looking at DEEP TIME!!!! Also, don't forget that we'll be looking at your evaluation on your IA soon as well. Keep working! We're almost there! If you have some time and sympathy for a fellow senior working on their Math IA, please complete the following survey: https://forms.gle/BzEGJEW25HKfH4v29 Honors Biology - Behavioral Data is what we explored today. Is it possible that these behaviors are learned, or is there a real genetic difference? We'll look at that question tomorrow. For now, you should write to the idea of whether you believe these birds are 2 separate species or not. This should go right below the notes you took today. Please also come prepared with at least 2 other questions you have that might help us answer this question better. You can place these questions on the left hand page of the same entry. Thursday IB Biology - Today you really only took a quiz. Yet, at the end of class we are looking to move on to trying to use everything we have learned this year, and in the past, to explain the macroscale workings (ecology, climate, etc.) of our world. To start out, we are going to make a visual timeline for what some refer to "Deep TIme", or the history of the earth. If we were going to make a giant 6 meter timeline for the wall, how would you Divide it up to proportionally show the various sections? AND how should we divide the different sections? This is your job tonight. Please come prepared because I am going with what you suggest . Here's a website that has the image I showed today: https://www.ck12.org/book/ck-12-biology-advanced-concepts/section/10.5/ Also please bring in whatever you have constructed for your evaluation on your IA. Watch this by Tuesday: Rise of the Mammals: https://www.pbs.org/wgbh/nova/video/rise-of-the-mammals/. List all of the names of the researchers invloved in this movie, what their title is, and what they contributed to the "Story." Can the time inheritance, etc. Not due until Tuesday, Tuesday, Tuesday! Next, if you have time, please complete the following survey for a fellow senior who is trying to collect data for their math IA. This is not the same person as last time. https://forms.gle/c5hc2dCRQSXQhHRP6 Honors Biology - So today you looked at data from a "common garden" experiment, biochemistry of the juncos, and a map of San Diego to determine if geographic isolation might be occurring with our two populations. https://www.google.com/maps/place/San+Diego+County,+CA/@33.0119178,-117.4069129,148026m/data=!3m1!1e3!4m5!3m4!1s0x80dbeb3023ff601d:0x350dfd2beb800728!8m2!3d32.7157305!4d-117.1610966 By the end of the day you then put down your ideas, taken from the data sets, as to if the UCSD and the Mt. Laguna Juncos are different species. You should have also attached data to why you think the way you do. Tomorrow this will be a very important discussion. Please have some solid points to argue. Friday IB Biology - https://www.ck12.org/book/ck-12-biology-advanced-concepts/section/10.5/ Using the assignment your class designated for you, your work should: Should be in your own words Be colorful Have unique information that defines the period Describe the hydrosphere, atmosphere, geosphere and biosphere of the time. Include major transitions before and after the time. Please make sure you thoroughly understand you part of this project before Tuesday. IF YOU ARE IN 1ST PERIOD and don't remember your assignment or were absent, Karrar made a list for you. Here's the link: https://docs.google.com/document/d/1aLLlKquJdmjXHeXnJ-vKTuKvx-xGC331H7xk7o50h4g/edit?usp=sharing OH, and Rady Children's hospital Summer Medical Academy applications are closing in two weeks! Be sure to apply if you would like to do it. It isn't cheap, but there are scholarships and you get a lot for your money. Email me if interested. Honors Biology - Today we watch a video on those Juncos and found out a little bit more about what the scientists think about these Juncos. https://vimeo.com/59871689 Then we took an assessment on speciation on Norfolk Island Robins and if we can protect them or not. Have a great weekend! Oh, BTW next week will end the first progress report. You will need your parent input completed. You may want to use this weekend to get it done.
