Unit 1: Flow of Energy and Cycling of Matter

Host Raiany Silva and watershed expert, Mike Kahle, explore a local stream in Cobb County. To understand how energy flows through an ecosystem, they conduct a visual survey and chemical test that students can do on their own or through organizations like Adopt-a-Stream.

Segment A: Introduction to the Flow of Energy and Cycling of Matter in an Ecosystem

Ecosystems come in all shapes and sizes, from massive mountain ranges to the creek in your own backyard. Learn about the key components to a healthy ecosystem in this segment of Let's Go Enviro.

Segment B: Investigation of an Aquatic Ecosystem

Have you ever wondered how you can help care for the ecosystems around you? Jump in with Raiany and Mike to test the chemical levels of a Georgia freshwater stream, and learn about the organisms that call it their home.
