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
