Today in class we learned about a fair test. We dropped two balls: a ping pong ball and a tennis ball. For a fair test to happen they needed to be dropped at the same height and same force so we wouldn't have an unfair bounce. In our experiment we used meter sticks and we leaned them against the wall to measure how high the balls bounced. We bounced the balls about five times and then we found the mean (average) of all the bounces of each ball. We found the difference between the two balls. I learned the importance of a fair test. Just one thing can throw your data off.
