Examples and explanations for the Environmental Science practice problems on positiveSTEM.org

I created the Environmental Science course on PositiveSTEM.org because I wanted my own students to be able to master the skills needed to be successful in AP Environmental Science, and now I'm trying to empower students and teachers around the world to learn how to solve the math problems in APES because analyzing data and performing calculations are an important part of being able to solve real environmental problems!

The videos here can also be found in the Lessons tabs of the skills on the site.
