Welcome to AP Biology 2011! Introduction to AP Biology: Instructor: Angie Shroufe Email address: shroufea@nclack.k12.or.us Textbook: Biology-Campbell, Reece and Mitchell In the spirit of examining our own place in the world, I am hoping that during the summer you will enjoy the time to enrich, relax, and recharge the mind and body. It is my hope that you will complete the summer assignment with the intention of stimulating interest and covering some important content connected to the start of our school year together. The major concepts of AP Biology are as follows: 1. Molecules and Cells: Chemistry of Life, Cells, and Cellular Energetics 2. Heredity and Evolution: Heredity, Molecular Genetics, Evolutionary Biology 3. Organisms and Populations: Diversity of Life, Structure and Function of Plants and Animals, and Ecology Summer Assignments for AP Biology: Please read this entire packet carefully so you know the points and due dates for each assignment. If you have any questions about the assignments, feel free to email me. The summer assignments will count as part of your first nine weeks grade. Assignment #1: Email me at shroufea@nclack.k12.or.us using your school email address and respond to the following: A. Brief introduction of yourself including your science/academic background and something unique about you. B. Why you are taking AP Biology? C. Why you think you will be successful in AP Biology and on the AP Exam? This assignment must be completed August 25th and is worth 15 points. Assignment #2: Go Biology! Summer Poster Using the list below, design a poster that photo documents biological experiences you had during the summer. Obviously you are not required to do all the following but choose at least three from the list (or your own list). Take pictures and make a poster of your experiences. This will be used during the first day of class to introduce who you are to the class. Bring your poster to class on a on the first day. Please have fun with this assignment…show some of your fun personality! Instead of driving, ride a bike or take a walk. Where did you go? Get wet in a downpour. What other factors are measured when talking about weather? Follow a stream to its headwaters or mouth. Do you know what these words mean? Speaking of water, where does yours come from? Watch an ant colony. What behaviors did you observe? Study the waves at the beach. Why do waves exist? Go into the wetlands and smell decomposition at work. Watch the Discovery Channel. What did you watch? Read National Geographic. What did you read? Figure out why dew forms on the grass at night, but not every night. Lie on your back and observe the stars and look for constellations. Climb Mt. Talbert (or another mountain) and look at all the different flora. Do you know what flora means? Look up what “metamorphic” means. What about igneous? Go find these rocks! Play around with Google earth. What places did you see? Grow your favorite vegetable. Did you also eat it? Look at a big tree and determine where all the mass came from. Go fishing. What types of fish did you catch? Use sunscreen and explain why you should. Count the number of bugs you see in 1 square meter in a wooded area…turn over stones and logs to see more. Go camping. Where did you go? Keep a journal of the different birds you see. How many different birds did you count? Visit a farmer’s market. Why is important to buy local? Buying organic food? Not buying organic food? Does it matter? At the pool? Figure how much water it takes to fill up the pool. Locate your local watershed on a map. Try to do a “waste free” day in your house. Do a media fast. How long did you last? Go snorkeling and look at the diversity of life under the water! Go for a walk and count the number of different animals and plants you see. Go to the zoo and see the variety of animals. How are the animals different/similar? Read an article relating to biology. What was it about? What did you find amazing about the article? This assignment must be completed by the first day of class and is worth 20 points. Assignment #3: Ecology Chapters Review I am providing you a set of outlines, objectives and vocabulary for the chapters in the textbook that will discuss the topic of ecology. You will not have the textbook checked out to you until registration so you are welcome to buy a used copy of the book to use on line, research the terms/objectives using the internet, or wait until registration to get your copy of the textbook to finish this assignment. A. Define and learn the bold-faced Key Terms for each chapter. I don’t simply mean to define the terms…discuss how the terms relate to the topics of the chapter outline. There will be some definitions in your summary, but it is important that you try and describe how these terms relate to the topics. B. Summarize the bold-faced Objectives for each chapter. Think of the objectives as questions for you to research and answer. C. Chapters copied in the summer packet: Chapter 50: An Introduction to Ecology and the Biosphere Chapter 52: Population Ecology Chapter 53: Community Ecology Chapter 54: Ecosystems This assignment must be completed by the second week of class as you will be given a test over the information discussed in these chapters. The test will count as a test score for your first nine week grade.
