Science Fair Project Complete

Well as several months of this project.  The Science Fair Project is complete and the board taken to school.  It has kinda been a monkey on our back but as of yesterday the project was turned in.

 

Charlie tested whether a tennis ball heated or frozen effects the balls bounce height.  It does.  The balls that are heated bounce slightly higher.  The balls that are cold actually bounce less .  Of course we tested room temperature balls to get a baseline.

He picked out the colors for his board.  It is a touch hard to look at. 

I think the real winner in all of this was Tigger , the dog, as he got 12 newish tennis balls. That is doggie heaven.
