A Rolling Inquiry

Very "spur of the moment" this morning, several boys began rolling and forming plastercine balls and then rolled them on the floor. This led to an inquiry as to what kind of ball would roll the farthest.

We made big, small and medium sized balls. Some were soft, some were hard, some were bumpy and some were smooth. Tyler predicted that "the small ball will roll the fastest because it is the lightest and the big one, because it is big and fat, it won't move that fast".

We then very excitedly tested their predictions in the hall.

We discovered that the large, hard, bumpy  one did not roll very far.

However, the medium, smooth soft one went the farthest!
