This means that the course should emphasize how scientists use their observations and readings to ask questions that can lead to new experiments. These experiments 1 build on the work of others and eventually lead to additional evidence on different topics. This investigative process will be used throughout this AP Biology course. It is important for students to become excited with discovery as they ask and answer their own questions about natural/biological phenomena that they see, read about, or experience in the laboratory and field. In addition, it is critical that students connect new concepts with what they know, with each connection they help themselves build a solid framework of biological knowledge and scientific know-how. This framework will help students to enter their future, prepared for whatever may lie ahead of them. Textbook/Resources: Reece, Jane et al., Campbell Biology, 7th Edition. Benjamin Cummings, 2005. [CR1] Additional Materials: AP Biology 1 & 2 Student Workbooks, BioZone, 2012. CR1: Students and teachers use a recently published (within the last 10 years) collegelevel biology textbook. Each student has access to the investigations contained in AP Biology Investigative Labs: an Inquiry Based Approach, as well as other laboratory investigations as deemed necessary. Course Organization This course is structured around the four big ideas and the enduring understandings identified in the Curriculum Framework. [CR2] All essential knowledge will be taught and all learning objectives will be addressed through this curriculum. The course will focus on inquiry-based laboratory work and the use of the seven science practices in both lab and non-lab activities. The four Big Ideas are: Big idea 1: The process of evolution drives the diversity and unity of life. Big idea 2: Biological systems utilize free energy and molecular building blocks to grow, to reproduce and to maintain dynamic homeostasis. Big idea 3: Living systems store, retrieve, transmit and respond to information essential to life processes. Big idea 4: Biological systems interact, and these systems and their interactions possess complex properties. CR2: The course is structured around the enduring understandings within the big ideas as described in the AP Biology Curriculum Framework. Students will be given a copy of the big ideas and enduring understandings to self-monitor mastery of these major organizing tools. The big ideas and enduring understandings will also be posted in the room. As connections are made across big ideas, a line will join the related enduring understandings, visually building a web of relatedness as the course progresses. The learning objectives will be used as a guide to build the rest of the class discussions, not as a checklist to be marked off through the year, but as a way to help students learn a focused amount of biological content with the use of specific scientific process skills. Skills will be practiced every day, not 2 necessarily all skills every day, but each day at least one skill will be used to introduce the biological content students study. [CR2], [CR3a], [CR3b], [CR3c], [CR3d], [CR4a], [CR4b], [CR4c] & [CR4d] To help students apply biological, scientific knowledge and critical thinking skills to major issues of social concern, they will read articles and view films that involve biotechnological advances and phenomena with severe environmental impact and implications. Students will follow with a written discussion informed by viable sources, explaining the significance of, controversy surrounding, and impact of these issues and technologies. Through these activities, students are challenged with opportunities to see applied biology beyond their textbook content. [CR5] Investigative Component Laboratory investigations make up a minimum of 25% of instructional time. [CR7] Students will conduct a minimum of eight inquiry-based investigations (two per Big idea). [CR6] Supplemental labs and activities are also used to widen the range of topics covered in a hands-on, discovery mode. By undertaking a variety of investigations throughout the course, all seven science practice skills will be used by students on a regular basis with a goal of leading students toward open inquiry investigations. The science practice skills need to be honed over the entire course and reinforced through opportunities to make observations, ask questions based on those observations, and investigate their own questions both in and out of the designated lab times. It is critical for me, as an instructor, to help students discover how the biological world works as we know it--and to learn how to investigate the biological world that is still unknown. That is why the investigations are a key to this entire course. Students will maintain a written record (lab notebook) of investigations conducted. In addition, they will be asked for the following throughout the course: [CR8] Formal lab report that emphasizes the development and testing of a hypothesis, the ability to organize collected data, and the ability to analyze and clearly discuss the results. Poster presentations (create poster with main investigation components; present to small groups or whole class; field questions). Self-assessments of their ability to work in group investigations that will often be conducted in teams of 2 or 3 in order for students to develop group skills and learn the importance of collaboration among scientists. 3 CR5: The course provides students with opportunities to connect their biological and scientific knowledge to major social issues (e.g. concerns, technological advances, innovations) to help them become scientifically literate citizens. CR7: Students are provided the opportunity to engage in investigative laboratory work integrated throughout the course for a minimum of 25 percent of instructional time. CR6: The studentdirected laboratory investigations used throughout the course allow students to apply the seven science practices defined in the AP Biology Curriculum Framework and include at least two lab experiences in each of the four big ideas. CR8: The course provides opportunities for students to develop and record evidence of their verbal, written and graphic communication skills through laboratory reports, summaries of literature or scientific investigations, and oral, written, or graphic presentations. Course Schedule Big Idea 4: Interactions Big Idea 3: Information perform data analysis & evaluate evidence work with scientific explanations/theories connect & relate knowledge 5. Big Idea 2: Energy Processes plan & implement data collection strategies 4. Big Idea 1: Evolution engage in scientific questioning 3. 7. use mathematics 2. 6. use representations and models 1. The following table describes how the enduring understandings/essential knowledge statements, learning objectives and seven science practices are the focus of each unit within the course. Due to the reduction in required content for AP Biology, all sections of each chapter will not be covered and/or may be used for reference as needed. The outlined timeline is approximate. Assignments include many ways to meet the objectives (worksheets, readings, dry labs, wet labs, Free Response writing, projects, etc.), and a few of these activities have been elaborated upon in order to fully demonstrate the incorporation of curricular requirements. These assignments connect biological content across big ideas.
