Project Water Science. General Science High School Level.

This teacher's guide presents 12 hands-on laboratory activities for high school science classes that cover the environmental issue of water resources in California. The activities are separated into three sections. Five activities in the section on water quality address the topics of groundwater, water hardness, bottled water, water purity, and water purification. Four activities in the section on water and the environment address the topics of water clarity; rainfall, geography, and vegetation patterns in California; toxins in water; and water ecosystems. Three activities in the section on water and people address the topics of water distribution, water conservation, and water treatment. The guide contains a glossary of 34 terms. The attached "Layperson's Guide to Drinking Water" explains some of the major concerns and controversial issues about today's drinking water and the kind of decisions that need to be made. It also contains a sliding chart of water facts, and a California Water Map. (MDH)
