Today, we did an experiment. The experiment was when we put some tennis balls in the freezer and left some balls in our classroom at room temperature. We wanted to see if the temperature of a tennis ball affects how high it will bounce. We got two meter sticks. Then we taped them on top of each other against the wall. Next, we got one freezer ball and dropped it from 1 meter. Then we got a room temperature ball and dropped it from 1 meter. We did this 5 times! Our hypothesis was correct!!! We found when the ball are cooler it doesn't bounces as high as the room temperature balls.
