My Live from Mars homeschooler's class did this experiment but I had help from a retired scientist who helped to keep the boys on track and doing the math. He made a track out of wood (triangle) for the spheres to roll down and used different sized spheres. Each one had to be weighed first. The craters(box of flour with orange tempera dry paint) had to be measured. I still don't understand the math but the boys seemed, too, at least the 6 and 7 graders. We used the teacher's manual from Live From Mars. Another one the scientist did was drop different sized spheres into a tub of margarine. Different weights went different depths into the margarine (until it got too warm, he,he) and made different width craters. The younger kids loved this one. **************************************************************** Diane Smith dianes@halcyon.com http://www.halcyon.com/dianes Seattle, WA Foundation for Educational Choice - http://www.halcyon.com/maywood Kidlink KIDPROJ Assistant - http://www.kidlink.org/ ***************************************************************** Researching Clark,Paxton,McIlvaine,Campbell,Morrow,Morrison *****************************************************************
