WHAT'S IN THE WATER?
After a heavy rainfall, students are to collect samples of running, muddy water in glass jars. Label the jars with the location of the water. Let the water stand for several hours until the contents have settled.
From your observations, you will realize that moving water carries materials and that the materials settle out of the water at different rates. Compare the kinds of sediments collected from the different locations.
Those students who live near running water (streams, creeks, etc.) can collect some specimens whether or not it has rained. Those who have ponds can collect some pond water for comparison.
Wash your hands. Use soap.
