AP BIOLOGY SYLLABUS Westside High School Mrs. Isengard M.S. 2014-2015 Course Overview This course is designed to be the equivalent of a college introductory biology course usually taken by biology majors during their first year of college. It aims to provide you with the conceptual framework, factual knowledge, and analytical skills necessary to deal critically with the rapidly changing science of biology. Some of you, as college freshmen, will be permitted to take upper-level courses in biology or to register for courses for which biology is a prerequisite. Others of you may complete a basic requirement for a laboratory science course and will be able to take other courses to pursue your major. Successful scoring on the AP Biology Examination, given by the College Board in May, determines how colleges award credit. You should check with your intended university to determine their credit policies for AP Biology. Usually a score of 3, 4, or 5 on the exam will earn some amount of college credit. Since AP Biology includes the topics regularly covered in a college biology course for majors, the textbooks used for AP Biology are those used by college biology majors and the kinds of laboratory activities done by AP students are the equivalent of those done by college students. The AP Biology course is designed to be taken after you successfully complete an introductory course in high school biology and one in high school chemistry. You must possess excellent skills in reading and writing, as well as in the interpretation and analysis of data. The intensity of the coursework demands that you put forth a significant amount of time and effort to succeed. You will be challenged daily so you must put in the time to read, study, prepare for each class, ask questions, complete assignments, and prepare for this exam. Your motivation will strongly dictate your success in this class. Philosophy I have a passion for teaching. This science is a doorway through which students can learn to cure communicable diseases, reverse the effects of genetic disorders, conserve our earth, save species from extinction, develop new and better foods to feed the hungry, as well as other world-changing skills. I will take my students beyond learning basic facts to developing overarching understandings and the important skills of reading for meaning, writing with a purpose, and interpreting/analyzing data. Necessary Materials Textbook Class Notebook - loose-leaf binder is recommended 4 Function calculator (SCIENTIFIC CALCULATORS ARE NOT PERMITTED ON AP BIOLOGY EXAM) Colored pencils - for graphing, microscope drawings, and dissection drawings The text for this course is Biology, 8th edition by Solomon, Berg, and Martin (2008, Thomson/Brooks/Cole). This book also contains the Interactive Study Partner Online Access Code. http://login.cengagebrain.com/cb/register.htm?method=loadRegistrationForm&nr=y# This is a wonderful resource for you to use throughout the year but it must be returned at the end of the year. There are also tons of websites and study guides available to help you and as always, your teacher will be your best resource! The AP Biology Examination The AP Biology Development Committee develops the AP Biology Examination so that it is representative of the topics covered in college-level introductory biology courses for biology majors. Accordingly, goals have been set for percentage coverage of three general areas: I. Molecules and Cells, 25% II. Heredity and Evolution, 25% III. Organisms and Populations, 50% These three areas have been subdivided into major categories with percentage goals for each major category specified. The percentage goals serve as a guide for the design of the AP Biology course and are used to determine the time devoted to each category. The examination is constructed using the percentage goals as guidelines for question distribution. The AP exam is given in May. It is three hours in length and consists of two timed sections. Section I contain 69 questions (63 multiple choice and 6 grid-in questions and lasts 90 minutes). Section II has 8 free-response (essay) questions and also lasts 90 minutes including a 10 minute reading period. Section I (multiple choice) accounts for 50% of the examination grade and Section II free response accounts for the remaining 50%. Teaching Strategies Throughout each class period in this course, I will employ a variety of teaching methods. Below is a list of these methods: Lecture (with daily stress on how each topic relates to the various four underlying themes of biology) Class discussion Lab work (Pre-lab assessments are to be completed before lab) Research-using scientific peer reviewed articles Computer work-online lab preparation, simulations Class debate on topics of biology in the news (effects on society) Independent and group work Course Timeline This course meets everyday for 90 minutes for the entire year of 180 days. This course has been designed to teach the four major themes of biology or big ideas. Students are given the opportunity to engage in student-directed laboratory investigations throughout the course for a minimum of 25% of instructional time. Students will conduct a minimum of eight inquiry-based investigations (two per big idea throughout the course). Additional labs will be conducted to deepen students’ conceptual understanding and to reinforce the application of science practices within a hands-on, discovery based environment. All levels of inquiry will be used and all seven science practice skills will be used by students on a regular basis in formal labs as well as activities outside of the lab experience. The course will provide opportunities for students to develop, record, and communicate the results of their laboratory investigations. Science Practices (SP) 1. The student can use representations and models to communicate scientific phenomena and solve scientific problems. 2. The student can use mathematics appropriately. 3. The student can engage in scientific questioning to extend thinking or to guide investigations within the context of the AP course. 4. The student can plan and implement data collection strategies appropriate to a particular scientific question. 5. The student can perform data analysis and evaluation of evidence. 6. The student can work with scientific explanations and theories. 7. The student is able to connect and relate knowledge across various scales, concepts and representations in and across domains. To simplify, these major themes have been condensed from eight themes in previous years into four big ideas as of 2012(according to the updated 2012 AP Biology Course Description). . Updated 2012 Four Big Ideas: Big Idea 1: Evolution Big Idea 2: Cellular Processes: Energy and Communication Big Idea 3: Genetics and Information Transfer Big Idea 4: Interactions Integration of General Topics to the Four Big Ideas of Biology and Science Practices for Student-Directed Investigations* * All Science Practices (SP) are addressed in these activities Big Idea 1: Evolution (Also coincides with Big Ideas 3 & 4) AP Lab 3 BLAST Activity: Students use NCBI to compare DNA and protein sequences for organisms to test student-generated hypotheses on their relatedness. AP Lab 2 Hardy-Weinberg: Spreadsheet development to investigate factors affecting Hardy-Weinberg Equilibrium.
