The golf ball is harder than the rest of the balls you used. It will cause the floor to deform more than the rest of the balls in the experiment. The wooded floor when deformed is considerable less elastic than the golf ball so the deformation of the floor causes a larger loss of energy. You'd probably get a similiar result with dropping a glass marble on the wooden floor then comparing that drop with a drop on a smooth hard floor like torazzo(is that spelling right?) or marble-like floor. I do a gee-whiz lab similiar to yours and have the students predict how many bounces the ball will make before it effectively(bounce less than .2 cm) stops and have them actually count the bounces. That's my $0.02 Larry
