A "hot" experiment
Today we did an experiment using hot wheel cars and two taped meter sticks, it was pretty fun just playing with cars during science!
The first day we talked about friction, which is the force that makes things stop when they go on a different surface which makes the two rub together and slow down. We also talked about Gravity, the force that holds us down on the earth. Then we taped the meter sticks and made a hypothesis about if the number of books would effect how far the car rolls.
The second day we did the experiment by stacking books to put the meter stick on and rolling the car down the sticks.
And after we did all that we calculated the averages and made a bar graph showing our averages. So we had an awesome time doing and learning about force and motion in this fun way.
