Hands-on lab activities plus video provide multi-learning
approach to science. Measure the pH of water samples, investigate effects of rain on
plants and soils, create acid rain posters, chart the path of acid rain from source to
deposition, and estimate the contribution of automobiles to the acid rain problem.
Includes the videotape Acid Rain: The Invisible Threat, Teachers Guide, and enough
materials for nine lab stations. Recommended for grades 7 through 12.
