AP Environmental Science
What have you gotten yourself into?
What is AP Environmental Science?

An interdisciplinary study that integrates
information and ideas from natural science:
Biology, Chemistry, Physics, Earth Science

And social sciences:
Economics, Politics, Ethics
The Course
 The
goal is to provide students with
- scientific principles, concepts & methodologies to
understand interrelationships of the natural world
- to identify & analyze environmental problems
- to evaluate relative risks
- to examine alternative solutions
The Course

Six Major Unifying Themes
- Science is a dynamic process
- Energy conversions underlie ecological processes
- Earth as an interconnected system
- Humans alter natural systems
- Cultural context of environmental problems
- Survival depends on sustainable systems
The Course

APES demonstrates the Nature of Science
- Science is a process
- Science is a method of learning more about
the world
- Science constantly changes the way we
understand the world
Prerequisites

MOST important prerequisite: Desire on the part
of the student

A Solid background in Biology and Chemistry

At least one year of algebra
Students Taking APES

Appeals to both traditional and alternative
learners

Tends to score lower than other science APs due
to integration of science disciplines

Lends itself well to inquiry-based, hands-on
learning
