Create a Bacterial Ecosystem - COSEE Coastal Trends

Lesson Plan 

In this activity, students mix mud, water, a carbon source, and a sulfur source together in a clear bottle to create a stratified “column” of bacterial communities. Activity requires time to set up in the classroom as well as periodic observations as the "column" stabilizes (4-6 weeks)

Concept: Ocean microbes
