Testing our vehicle

Yesterday we tested our car with another grade 2 class. First we tested without the weight to see how it rolled. Then we tested it with a weight of 1 kilogram. Guess which car won?
- #18

Ours did!

Our car was the strongest one. It was the fastest and it rolled further than the other car.

- #9

Our car stayed together and held the weight.

-# 20

Our car stayed on the ramp and it went straight.
