Earthworms are active in the springtime and are involved in recycling the leaves in local woods.
Most of this activity is nocturnal and involves a number of species. Feeding takes place primarily from the burrow entrances. The worms accumulate middens at their entrances that serve as evidence of their burrow locations. Visit this website and perhaps you will generate a testable hypothesis regarding the growth of plants under varying amounts of artificial vs. minimal lighting. We have a light meter to aid in such a project.
