Algae and brine shrimp
Brainy Briny's
A living food web your class can measure.
Brainy Briny's puts algae and brine shrimp together in a clear bag or beaker. The algae grow on light. The brine shrimp eat the algae. Students watch a real producer and consumer share an ecosystem, and they measure what happens instead of reading about it. The same kit runs lessons from kindergarten through college.
