Instructional materials and suggestions for conducting a whale watching field trip are contained in this curriculum packet for secondary science teachers. It is one unit in a series of curricular programs developed by the New England Aquarium Education Department. Activities and information are organized into three sections: (1) pre-trip activities (providing fact sheets on cetaceans, worksheets on specific whales, and a vocabulary list); (2) trip activities (including descriptions of cetacean behaviors and a data sheet for recording observations); and (3) post-trip activities (identifying project areas and suggesting enrichment experiences). Preparatory and follow-through instructional strategies are offered and a list of resources is also provided. (ML)
