Lake Michigan–A Fragile Ecosystem

by: Tom J. McConnell, Joyce M. Parker, and Janet Eberhardt

Commercial fishermen have noticed declining numbers and smaller sizes of the fish they catch in Lake Michigan, and they want to know how the government’s stocking program is affecting their catch. In this problem, the challenge to students is to help find out what could be happening to the fish and if people should be concerned and back their decision with evidence. A materials list, teacher background information, safety practices, references, assessment, and outcomes are provided. This book selection includes the Table of Contents, Preface, Catalog of Problems, Acknowledgments, About the Authors, References, and Index.

NSTA Press produces classroom-ready activities, hands-on approaches to inquiry, relevant professional development, the latest scientific education news and research, assessment and standards-based instruction.
