Can Fishing

In this outdoor activity, learners go "can fishing" and discover the kinds of aquatic organisms that live in and on submerged cans. Discarded bottles and cans surprisingly provide protection for young aquatic organisms, because the young are small enough to fit inside while larger predators stay out. Learners consider how human activities improve or harm the quality of animal and plant habitats. This activity can be combined with a cleanup day and/or with the Litter Critters activity from the same source. The animal observation part of this activity can be expanded to younger ages, if can retrieval from the natural water bodies is handled by an older learner or adult. (Preparation time will vary depending on how many can grabbers are needed).
