Drop into a plastic wading pool a large number of different colored eggs; the eggs should be glued shut so they don't come apart during the activity. There should be the same number of eggs (6-10) of each color. Cover the eggs with Styrofoam packing peanuts, popcorn, or sand. Arrange students around the pool. Assign each student a different color. Then give students a time limit (maybe 2 minutes) to uncover as many eggs as they can of their assigned color. If a student uncovers an egg of a different color, he or she should rebury the egg so the student who is looking for that color will not be able to grab it from the surface of the pool. At the end of the time limit, count the number of eggs each student uncovered. At an award assembly, recognize students who found the most eggs.  Alternative Activity: Bury marbles and let students hunt for marbles of any color. How many marbles does each student uncover within the time limit?
