AP Environmental Science --- 2009/2010 Course Description and Syllabus

 

Class Profile

AP Environmental Science is a year long course offered to Juniors and Seniors with a maximum class size of 20 students. The class meets Monday through Friday for 45 minutes each day. There is at least one Saturday meeting per trimester for extended field labs. The prerequisites for APES include a year of biology and chemistry with at least 90 or above in each course. Exceptions can be made with the permission of the instructor.

 

General Course Objectives

Demonstrate the interdisciplinary nature of environmental issues through numerous case studies.

 

Stay abreast of current events that pertain to course topics through the use of periodicals and various news media outlets.

 

Provide opportunities for students to apply knowledge and to think critically through group discussion and debate.

 

Allow students to do science as well as learn about it through various activities and experimental laboratories. Activities and lab exercises occur at least one period per week.

 

Require that students formally write up experiments using a standard scientific writing format (Lab Report format outlined in Molnar, 2005)

 

Give each student the chance to present and teach complex ideas to his peers using current technology.

 

Required Texts

Botkin, Daniel B., and Edward A. Keller. Environmental Science: Earth as a Living Planet. Fifth Edition. New York: John Wiley, 2005.

COURSE OVERVIEW

Advanced Placement Environmental Science is a lab science course that focuses on the interactions between mankind and the natural environment. This course explores the scientific factors behind many current environmental problems and the ways in which our current lifestyles have been, or can be, altered to make improvements. Throughout the course, the connections between our quality of life and the health of natural systems are emphasized. Unlike many science courses, APES combines rigorous laboratory work with a round table discussion class format. Current periodicals are often used to explore examples of course material. At least two Student Symposia, which involve pairs of students teaching various course topics, will be held during the fall and winter trimester.

 

The course material for APES has been organized into units and the depth of coverage is consistent with the College Board’s Advanced Placement Environmental Science course outline.  An approximate timeframe for each unit is provided below, however, I have tried to leave at least 1 week each trimester for review, coverage of current events, and unforeseen delays. Activities and readings may be added or subtracted occasionally. Tests will be given on Tuesday or Friday only.

Student Evaluation

Final Grades each trimester are based mostly on Unit Tests and Major Lab Reports (60%). Class Participation makes up a small part of the course average (15%), along with Final Exams given at the close of each trimester (25%).  Unit Tests are primarily multiple-choice with one or two free response questions. Before each test, students are given approximately eight free response questions and are asked to prepare answers for each of the questions. The free response questions on the test are chosen by the instructor out of the eight provided. The Class Participation grade is assigned according to a student’s contribution to class activities, overall performance on reading quizzes, and participation in class discussion. Also, students are expected to outline text chapters and create questions as the reading material is assigned. Notebooks are checked at the close of each grading period (4, 8, ~12 weeks). Notebook grades will be assigned according to the organization and completeness of reading notes and related activities. The notebook grade is a standard 100 point test grade that is updated each grading period.
