Students observe the feeding behavior and success rate of blue gill feeding on brine shrimp in two different environments; one with seagrass and one without.*
*See "Predator Prey Interaction" for a cheaper alternative activity that can be used without the living organisms.)
Students will gain a better understand of the following ecological service provided by underwater grasses: underwater grasses provide shelter for wildlife.
The bluegills may live for many months, so if you do not wish to maintain a fish tank in your classroom, ask the students if they would like to adopt some new pets! They should NOT be released into the wild.
