AP Environmental Science

Students cultivate their understanding of the interrelationships of the natural world through inquiry-based lab investigations and field work as they explore concepts like the four Big Ideas; energy transfer, interactions between earth systems, interactions between different species and the environment, and sustainability.

New AP Environmental Science Labs

Ten new laboratory investigations are available in AP Classroom to use with your students. These labs are in addition to the nine that were made available in the 2022-23 school year.

AP Environmental Science Course at a Glance

Excerpted from the AP Environmental Science Course and Exam Description, the Course at a Glance document outlines the topics and skills covered in the AP Environmental Science course, along with suggestions for sequencing.

Course Content

Based on the Understanding by Design® (Wiggins and McTighe) model, this course framework provides a clear and detailed description of the course requirements necessary for student success. The framework specifies what students must know, be able to do, and understand, with a focus on big ideas that encompass core principles and theories of the discipline. The framework also encourages instruction that prepares students for advanced environmental science coursework.

The AP Environmental Science framework is organized into nine commonly taught units of study that provide one possible sequence for the course. As always, you have the flexibility to organize the course content as you like.
