Green & Blue learned about the rain forest and created rain sticks.
Red & Purple played a game to learn about biomagnification. Some of the students were worms, and they ate "plankton." Some of the students were fish and ate worms, and one of the students was an osprey and ate the fish. Once the game was over students discovered that some of the plankton had been contaminated by DDT, and so the poison had moved up the food chain (biomagnification).
The osprey is eating the fish.
The worms are eating plankton.
The Black & White group played a game to learn how energy is transferred up the food chain. These cups represent the producers, primary consumers, secondary consumers and top consumers. The water represents energy. All of the cups but the top consumer cups had holes at the bottom. Students learned that each time energy is transferred up the food chain, 90% of it is lost.

And the red and purple groups learned about the estuary, in a fantastic song that Valerie taught them!
