This compilation of 57 activities adapted from 32 different publications addresses 5 of the 18 needs and recommendations for water quality curricula made by Elaine Andrews in the publication "Assessing National Water Quality Education Needs for the Nonformal Youth Audience." The needs include: approaching water-related ecosystems in a more integrated way; providing activities that better integrate ecology and science study with everyday life; rewriting materials to make them more appropriate for diverse audiences; making nontraditional learning choices more accessible; and reprinting high-quality materials no longer available. The hands-on activities are organized within a logical framework in five sections. The sections address the topics of: (1) the science of water; (2) the hydrologic cycle; (3) water uses; (4) water conservation; and (5) water pollution. Subsections within these topics address water properties; water movement, precipitation, transpiration, and evaporation; water needs; methods of conserving water; and types of pollution and necessary clean-up. The introduction includes a guide to using the book and the rationale for activity selection. (MDH)
