Dr. David Kupperman of Argonne National Labs gave Whittier 4th graders some hands-on experiences with gravity and its affects on objects in free-fall and on an inclined plane.
He also showed them how to measure time without a clock, parents of 5th graders everywhere are hoping this proves to be a scientific breakthrough in getting their child anywhere on time.
There was an interesting discussion that followed about gravity and how it affects objects in space as well as the possibility of getting to and living on Mars!
