Discrepant Events: Balloon in a Bottle
Will a balloon inflate easier in a big bottle or a small one?
A discrepant event is a result or a reaction that is unexpected. When students observe a discrepant event, they must ask themselves: why? Why didn't the observed materials behave in the expected way? What might be going on behind the scenes? How can we recreate the event and what are the forces at work?
A discrepant event is a fantastic way to pique curiosity and inspire inquiry. Why not try Balloon in a Bottle, yourself? This demonstration caught our science campers by surprise and inspired some incredible theories.
