The eagles select nests around the fish habitat. The game starts again with the eagles now catching fish and aking them back to their nests. Because the fish will go to cover when attacked, we allow the eagles only thirty seconds to catch fish. An eagle must take a fish back to its nest before going after a second fish. The eagles must catch a minimum of two fish to survive.
Recorders keep track of all of the data.
Discuss the results of the game with the class. Try to help them understand the relationship between bugs, fish, and eagles. Repeat the game and compare results. Repeat a minimum of five times in order to collect adequate data for graphing. Display a graph for students to see and then explain how a graph works.
