AP Biology Summer Assignment Ms. Chulapatrcheevin vchulapatrcheevin@tustin.k12.ca.us Hello lovely students! Welcome to AP Biology. To prepare for the rigor of the year ahead you will be completing the following assignments. Remember, biology is about approaching the study of life with curiosity, and seeing the complexity, mystery, and beauty of the natural world. Complete your assignments, have some fun, and don t wait until August to start! All parts of your summer assignment are due the second day of class: August 15, 2018. Part I: Read Chapters 1, 2, 3, 4 and 5 in Campbell s Biology textbook. Complete the attached study guides. Be prepared for an assessment and discussion on the first week of class. You will find an online textbook and additional resources at: https://tusd.haikulearning.com/vchulapatrcheevin/apbiologyfhs Part II: Biology Research Presentation Outline In first semester, you will give a presentation about a science research question of your choosing. Your presentation will be 8-10 minutes in length, and your date will be assigned the first week of school. This summer, choose a research question, summarize your topic, and find five (5) sources with information on your topic. See example below. You may choose any research topic, as long as it is based in science, and you find it interesting! Part III: Bonus Assignments (optional) Choose one or more of the following, each written response should be at least one page, single spaced. 1. Go to the tide pools/snorkeling /scuba diving. Take a photo of yourself. Take photos of 5 organisms and explain the limiting factors that might affect them, their special adaptations, and in which tidal zone they would be found. 2. Visit a zoo/botanical garden/aquarium. Attach ticket stub and take a picture with a sign to show evidence you were there. Take pictures of 5 different animals/plants there and describe the biome in which they live in and any special characteristics/adaptations they have. 3. See a science movie (science fiction is fine). Attach the ticket stub and take a photo of you being there (or in front of your TV). Describe 5 science themes you were able to find while watching the movie. 4. Explore your backyard/neighborhood. Take a photo with 5 plants/animals that are native to southern California. Discuss the organisms adaptations and where you found them. How do you know they are native species? 5. Go on a nature hike (suggestions: Peter s Canyon, Irvine Regional, Crystal Cove, etc.) Take a photo with a sign to show that you were there. Take pictures of 5 different plants/animals you see. Write about your hike. You should discuss the biome in which you are in and any characteristics, special adaptations you find in the plants/animals. See anything interesting? What trails did you go on? Did you get lost?
Sample: Biology Research Presentation Outline Research Question: Your question should be specific. For example: Can endangered areas and animals be saved by helping local people develop alternative economies like raising tropical fish or ecotourism? Summary: Provide a 1-2 paragraph summary of the science issues that you will be researching. While few would question that conserving a certain percentage of land or water is good for society overall, it has long been believed that protected areas economically impoverish, rather than enrich, communities living adjacent to them. Many communities worldwide have protested against the establishment of conservation areas near them, fearing that less access and increased regulations would imperil their livelihoods. However, a surprising study overturns the common wisdom: showing that, at least in Thailand and Costa Rica, protected areas actually boost local economies and decrease poverty. Protected areas can help local economies by attracting tourists who spend money in nearby communities, by protecting ecosystem services (such as water provision, flood protection, generation of non-timber forest products) which increase productivity, or through improved infrastructure and institutional development. However, protected areas also impose costs by restricting access to land and natural resources. So the question is whether the benefits can actually outweigh the costs at the local level.
