This investigation is designed to help students understand storm surges on Lake Erie. Activity A includes experiments and discussions intended to help students understand what causes storm surges on Lake Erie. Activity B considers how storm surges affect water levels and, in turn, coastal areas. The student booklet contains questions, experiments, graphs, and a test for both major sections of the investigation. The accompanying teachers guide contains some additional background information and the answers to the questions in the student booklet. (TW)
