Old CDs Make Good Wheels


August 15, 2002

I have seen used or scratched CDs used as wheels. In an 8th grade physical science class, which I worked with at one time, students designed several types of vehicles (depending on the unit of study). A couple students used the CDs as wheels on their mousetrap cars. I also keep sample and no-longer-usable CDs in a miscellaneous supply box for creative problem solving and other activities.
