With boys, grasshopper experiments can get a lot messier. DS7 found a dead grasshopper. With a friend, they devised an experiment to see how tough the body of a grasshopper was, and how it would react to force. They threw various objects at it and drew a graph depicting the level of impact (not sure how they assigned values). His conclusion - the body was very tough, and a rubber ball provided the greatest impact because the body broke apart."
I didn't have the heart to tell him it could be due to repeated blows
