However since it is a major threat to the environment, it is important that students learn how it occurs. All of the activities in this packet are hands-on and are designed to correlate with national science standards. Each activity contains information on the objectives, topics covered, time requirements, and materials or preparation required, as well as additional background information, ideas for follow-up, extension and additional resources. In a sample activity, students are read a story about a boy on vacation who observes some examples of possible point and nonpoint sources of water contamination. The packet includes picture cards that illustrate the story.
Students look at the pictures and decide which pictures show which type of pollution.
In another activity, students compare the water absorbing and runoff characteristics of different soil samples held in plastic trays. In a third activity, students fill an aquarium with several inches of progressively finer layers of gravel and soil, then add some water. The water sits at the bottom of the tank in the coarse gravel layer and is accessed using a turkey baster that represents a well drawing ground water from an underground source.
