In this outdoor, freshwater activity, learners explore the behavior and food preferences of crawdads (or crabs) by "fishing" for them with various baits. An extension of this activity is to mark learners' catches with red nail polish and release them back into the water, then try to find them on a later day to discover how far they may have moved.
