First, the 6th grade Science students did research about the value of watersheds, and the tests that can be done to determine the purity of their water. Then the students did various tests on the water that comes from a spring which is found on school property in back of the parking lot. They recorded these results in an Excel document.

Later they created trees in Sketchup, and placed these trees in back of the tennis courts in Google Earth, projecting what the land might look like, if the spring water were used to water the trees. The unit took five class periods to complete.
