I define this as a game, a project, a demonstration,a class group activity, a Power Point program, or just plain fun.
The object is to have students come up with something in science they have read about and ask the question - Who had it first. For example Sonar - actually bats, porpoises and even some birds had it before man ever thought of it.
The Activity contains information on pliers, hypodermic needles, jet propulsion, the eye, echolocation, smoke screens, fishing nets, electricity and Bolas. It also has a student worksheet where students can add their own examples.
