Science project

As a fifth grader, Red Chief participated in his school's science fair this year. He wanted to find out whether adding weight would make a Pinewood Derby car go faster.


There was some preparation to do before he could find that out. First he had to make a track.


Next, my husband rigged up some electronics for timing.


Finally Red Chief sent the cars down the track. And in case you wondered: yes, adding weight does indeed help the car go faster.
