Lessons
Microbial electrochemistry, one model at a time
Thirteen interactive lessons, from middle school to graduate research: three or four for each level. Every lesson is built around a microbial electrochemical system (MES) model you can open in the lab. Each one has a diagram, key concepts, a prediction to test, and a short check. Pick a level and a lesson, or follow a daily, weekly or monthly plan.
Ages 11–14
