These computer activities build on concepts presented in the acid rain Students Site, and allow students to put their new knowledge to use. A connect-the-dots game lets them construct pictures of things that are related to acid rain. There is also a word search (novice and advanced levels) in which they can look for terms related to acid rain that were presented in the Students Site. There is also ... Full description.

This page about acid rain for younger students describes both wet (rain, snow, fog) and dry (gas, dust) acid deposition and points out that both can be carried by the wind, sometimes for very long distances. It also explains the concept of acidity, how it is measured, and describes some of the harmful effects of acid deposition. Links to a glossary are embedded in the text. Full description.
