AP BIOLOGY SYLLABUS


 

 

AP® Biology                                                                Instructor:  Alexander Coke Smith

Syllabus                                                                      Term:  2009-2010 Academic Year

 

Personal Philosophy

Biology is without a doubt one of the most fascinating and most important scientific disciplines.  There was once a time when a scientist could claim to be an expert in virtually every field but currently the knowledge base within the biological sciences is so vast that being an expert in simply one area of study could require a lifetime commitment.  But in order to be scientifically literate in today’s scientifically demanding society, it is important to have a general knowledge of many areas of the biological sciences. It is with this in mind that I have presented a broad course of studies that covers in good depth many of the fascinating areas of this wonderful subject. 

 

Course Overview

Classes meet daily for approximately 56 minutes. Depending on our complicated schedule, we will have lab activities that may carry over in to after school hours. This makes it possible to not only do all of the 12 labs in the AP Lab Manual for Students but many additional labs and activities as well, resulting in a diverse and interesting hands-on laboratory program.

 

Our course is organized around the eight themes from the AP Biology Curricular requirements.   Students are required to read the textbook chapters listed on the syllabus, and take a test at the end of each unit. The course textbook is the 8th edition of Neil A. Campbell and Jane B. Reese’s Biology.

 

All students who take the AP Biology course are required to do an independent research project outside of class time. I assign this in September and it is due at and of February. Students do most of the work on it independently - at the library and at home.

 

I spend very little in-class time on preparation for the AP Exam other than to discuss some test-taking strategies. AP Biology Released Exams will be made available to students to aid in their preparation for the AP examination.  After school study-sessions will be available starting at the end of February.

 

 Required Text:  8th edition of Neil A. Campbell and Jane B. Reese’s Biology.

& Jane B. Reese, Biology, 8th Addition

AP Biology Includes and Emphasizes:

  • Applications of biological knowledge and critical thinking to environmental and social concerns  
  • The course includes a laboratory component that fulfills all of the objectives of the required AP Biology labs as listed in the Course Planner. Students will spend a minimum of 25% of instructional time engaged in hands-on laboratory work.

  • The integration of the general topics of biology through the eight major themes as specified in the Course Planner and AP Biology Course Description:

Science as Process

Evolution

Energy Transfer

Continuity and Change

Relationship of structure to function

Regulation

Interdependence in nature

Science, Technology and society

In addition to the above:  Diversity of life & the structure and function of plants and animals.

  

Course Planner

AP Biology is divided in to 11 units that vary in length from two to three weeks.  Every unit includes a hands-on laboratory exercise designed to integrate the topic of that unit into the eight major themes of the AP Biology Course Description. Throughout the time spent on each unit, we will discuss as a class how the topic at hand relates to and fits within each theme, and how these themes transcend all of the unit topics.  

Theme 1 – Science as Process – Students engage in a project (Radish Seed Experiment) demonstrating the use of scientific reasoning to solve a problem.

Theme 2 – Evolution – Students compare ecological time with evolutionary time and examine how they correspond.  Students will explore the concept of change over time as well as the diversity of life (with a survey of living things ranging from viruses, bacteria to higher plants and animals) produced through evolutionary processes.

Theme 3 – Energy transfer – Students are asked to describe the movement, conversion, and storage of energy within an ecosystem, usually originating with the sun, then stored and converted to chemical energy by autotrophs, then passed on to heterotrophs and/or dissipated as heat.

Theme 4 – Continuity and change – Students are asked to consider how specific changes to an ecosystem (geological, climatic, introduction of new organisms, etc.) can affect the organisms that live within it.

Theme 5 – Relationship of Structure to Function – Students consider how organisms are physically adapted to survive and reproduce in their environment. Detailed studies of plant and animal structure and function will be part of the curriculum as well.

Theme 6 – Regulation – Students are to understand how an organism’s regulatory mechanisms (such as those that control body temperature) serve to aid or hinder its survival in particular environments. (This should be considered as further study of the structure and function of plants and animals.)

Theme 7 – Interdependence in Nature – The very key to ecology – how organisms interact within their environment, and how they cannot survive without such interactions.

Theme 8 – Science, Technology and Society – Students are asked to consider how the population growth of human beings has influenced local ecosystems throughout history, and how it continues to do so, even to the extent of affecting the entire biosphere.

Teaching Strategies

This course will be divided in to four general teaching modalities:

            Hands-on Student-centered Lab Activitie

Lecture

Group work

Independent Discovery

 

The scope and sequence of the course will follow the basic themes presented above as well as the detailed timeline syllabus.

 

As often as possible I recycle previously-covered concepts and make a conscience effort to relate concepts covered in previous units to newer units to instill an “everything-is-interconnected” conceptualization of the biological sciences in my students. For example, the concepts of evolution, biochemistry, ecology, while being themes in and of themselves, will be interwoven throughout the course.

 

Lab Component

Working in pairs, students will do every lab exercise in the AP Biology Lab Manual for Students. They also do a variety of labs I have written myself or modified over the years from various sources.

 

Students do a lab every week, and they are required to turn in a write-up for each one. The level of these write-ups will vary depending on the lab. Some labs require only well-organized data summary and brief conclusions. Others, such as dissections and microscope labs, merely consist of a well-drawn diagram of what students saw. For labs that come from the AP Lab Manual, students must complete the graphs and answer the questions in the manual and present their findings in a specifically formatted manner. Independent research projects require a full lab report.

 

Students have one week from the completion of a lab to turn in their reports.

 

Student Evaluation

Unit tests = 65 % of final grade

Independent research project = 10 % of final grade

Lab reports, homework, and quizzes = 10-15% of final grade

Term Projects – 10% of final grade

 

Term Projects

Each term students complete a project that requires them to do independent work and turn in a report.

 

            First-Term: Radish Seed Experiment (Unit 1). Students design and carry out an experiment at home that tests whether radishes grow better in the light or the dark. This project emphasizes the elements of experimental design, as well as how to make graphs and tables for data presentation. Students submit a written lab report, which will be graded on experimental design, presentation and discussion of data.

             

            Second-Term: Original DNA/Genetic Code Papers (Unit 4). Students read one of the original papers on the discovery of DNA or the genetic code and give an oral presentation (and written report) to the class.

 

            Third-Term: Human Karyote Construction (Unit 6). Students prepare a human karyotype on paper at home.

 

            Fourth-Term: Owl Pellet Investigation (Unit 11). Students will reconstruct an owl pellet in the lab after the AP Exam. They are required to reconstruct the skeletons of all the animals the owl ate that are present in its pellet. This lab emphasizes comparative anatomy, and homology among mammals, as well as scientific reasoning.
