1 AP Biology Course Overview: This course is an intensive study in biological concepts that emphasizes inquiry based learning. It is structured around the four Big Ideas and the Enduring Understandings that are identified in the Curriculum Framework. Students will become the directors of their own learning as they plan and implement multiple investigations. Science is a never ending process with every investigation leading to another. Inquiry allows students to experience this process while making connections across the four big ideas and building a solid scientific foundation of knowledge and experience. The four big ideas are: 1. The process of evolution drives the diversity and unity of life. 2. Biological systems utilize free energy and molecular building blocks to grow, to reproduce, and to maintain dynamic homeostasis. 3. Living systems store, retrieve, transmit, and respond to information essential to life processes. 4. Biological systems interact, and these systems and their interactions possess complex properties. AP Biology is available to Juniors and Seniors as a science elective. The class meets 4 days a week for 48 minutes and 1 day per week for a double lab period of 96 minutes. All students must have completed an introductory biology class and completed or concurrently taking chemistry. At least 25% of instructional time is devoted to laboratory work that incorporates at least two labs for each of the four big ideas. Additional lab work will be completed to deepen students understanding and application of concepts taught throughout the class. The laboratory investigations used will allow students to work with and practice the seven Science Practices as defined in the Curriculum Framework. Laboratory work will be documented in a laboratory book, and presented in a various forms such as formal lab reports, group and individual presentations, and abstracts. Seven 1. The student can use representations and modes to communicate scientific phenomena and solve scientific problems. 2. The student can use mathematics appropriately. 3.

Your Inner Fish. Shubin, Neil (All students must read and complete a written assignment prior to the evolution unit of class.) Units of Instruction The big ideas are not taught as separate ideas but are intertwined throughout the unit. Students are given guided reading questions to accompany all text and journal readings that are required throughout the year. Journal articles are given at various times during the year to expand on classroom discussion topics and new innovations within various fields of study. Both formal and informal assessments are given on a regular basis. These assessments include end of unit exams, free response essays, quizzes, discussions, and projects. Unit 1: Nature of Science Timeframe: 4 days with 1 lab period Text Correlations: Campbell - Chapters 1, 2, and 3 2D Growth and dynamic homeostasis of a biological system are influenced by changes in the system s environment. 2E Many biological processes involved in growth, reproduction and dynamic homeostasis include temporal regulation and coordination. 4B Competition and cooperation are important aspects of biological systems. Discuss how biology is multidisciplinary. Introduction to inquiry based learning and how to set up and use lab books in the classroom. Scientific design of experiments.
