Tremendous Trebuchet

I've been waiting for Gavin to do this post, but I don't think that is going to happen. Homework, you know.
I was convinced after last year's late night science fair project that this year would be better. Okay, better by about four hours. Why does that kid put everything off until the last minute?!
Gavin's project was great this year.
He built his trebuchet kit he got for Christmas and tested six different projectiles to see which one would fly the farthest. He chose a small marshmallow, Skittle, wooden ball, metal ball, Whopper and a piece of popped popcorn. What do you think won? I picked the metal ball. Wrong! That got negative inches each time (meaning it landed behind the trebuchet). The winner, by quite a lot, was the Whopper.
Gavin had a great time launching everything (he tested each object six times to have an accurate measurement), his board looked great and he learned something about momentum and weight.
He received an Einstein award, the highest honor. I'm very proud of him (and very happy science fair is over for a few years!).

Update: We just found out today that Gavin is going on to District! Great job, Gavin!

Congratulations, Gavin! Your project looked so good! Your board was so colorful and well organized! I am sure your research was very interesting to all those who stopped by to see what you had done. We are so proud of you! Good luck at the District competition! We love you!
