The Senses of "Unknown Creatures"

In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses. Learners are given supplies to devise their own experiments and test the response of the earthworms to light, touch and chemicals. Learners collect data and draw conclusions based on this data. Learners return the earthworms to their natural habitat (a flower or garden bed) when they are finished with the experiments.
