The Gravitational Pull Does What? (Dropping Races)

We had a "dropping race" today in science to see how gravitation pulls things toward the center of the Earth.  Many students believed that the objects with more mass would fall quicker to the floor than the smaller objects.  (We discovered this through our predictions.)  Then we tested and boy, were we surprised!  We recorded our drops using a free ap called "Slow Pro" and watched them a second time after we did the drops.  A student dropped and another recorded each test.  We also had floor judges too.

We had a wondering during the class and because I was afraid to test these two objects for fear of tearing up the flooring, we googled it! (bowling ball and a tennis ball)





Our second wondering: ball bearing and a feather!
