Dear Rhonda, Your "shuttle" sounds wonderful!!! Try cratering with a xerox box top lined with plastic and full of flour. Pat the flour down, level it , and sift dry tempra paint (dark color) on top. Drop a marble and watch the crater...or toss a marble and note the splash pattern (This experiment is on the video fromNASA called Craters and Phases of the Moon.) You can also do moon cratering (MARS cratering) in the mud or sand. Have students gather 3 different sized rocks, none bigger than their fist, and drop the from 3 heights. Knees, waist and shoulder heights and measure the depth and width of the crater. Another one is Erosion using a box with sand and dirt mixed set at an angle and pour different amounts of water on the soil and watch the effects on the sand/dirt. Or in TUcson, just walk outside after a heavy rain and see the effects on the non cemented drainage for water effects on soil. Hope that helps some. If you want more information, just ask and we'll explain or send more experiments. Let us know whats happening! Renee and Michael ---------- Renee Crawley Email:craw3900@spacelink.msfc.nasa.gov
