First we voted on the type of ball we thought would push the tractor the best. Then, we made tally marks next to the ball we voted for. The metal ball had the most votes and they justified their prediction by saying the metal ball was the heaviest so it would have more force. Aren't they a smart group?!
We then tested the balls to see which would push the tractor the furthest.
Here are our recordings. We recorded our results in our Science notebooks. Above is an example.
Our Smartboard votes for the ball that we thought would move the tractor the best!
Our recordings of where the tractor ended up with each ball we rolled.
And below...what we noticed about our votes!
