Culturing Bacteria - COSEE Coastal Trends 
Lesson PlanSummary
Students collect water samples, plate the samples on suitable agar, and count bacteria colonies present in each sample to compare and contrast the types of bacteria living in a variety of aquatic environments.
60 minsCreate a Bacterial Ecosystem - COSEE Coastal Trends
Summary
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)
Using Genetic Techniques - COSEE Coastal Trends
Summary
Students conduct “virtual labs” to explore how scientists extract DNA from samples, amplify the DNA (PCR/Polymerase Chain Reaction), and study the DNA (gel electrophoresis).
