Does the arm length of a catapult affect projectile distance?

Haven't we all wondered about that sometime or another? That was Kaitlyn's question this year for science fair. Here she is at the fair with her project. (sorry about the blurry pictures, something is up with my camera!)
Earlier this school year, she built a catapult, with the help of her handy and crafty father.

Then she tested it out several times, gathering tons of data.


She won at the school level and went on to district...


Where she won 2nd place in the category of math and physics with a special award from the US Metric Association and one from the United States Air Force.

Yep, we're proud of our young scientist!
