Life in the Great Lakes. Earth Systems - Education Activities for Great Lakes Schools (ES-EAGLS).

This activity book is part of a series designed to take a concept or idea from the existing school curriculum and develop it in the context of the Great Lakes using teaching approaches and materials appropriate for students in middle and high school. The theme of this book is life in the Great Lakes. Students learn about shorebird adaptations, invader species, food webs, and biomass pyramids. Activities are divided into several subjects: (1) Organisms in the Lakes; (2) Ecological Relationships; and (3) Estuary Values and Changes. The activities are characterized by subject matter compatibility with existing curriculum topics. Several kinds of connections have been designed to assist teachers in finding the place where the new materials fit and also the justification for fitting them. The connections include a Framework of Seven Understandings developed by science teachers, science educators, and scientists to represent fundamental desired results of science education. Each activity in this book addresses a number of these Understandings and two or more Earth subsystems. Connections are also made to the National Science Education Standards and the Benchmarks for Science Literacy. (PVD)
