Today in class we learned how to create a fair test. We all thought of a procedure before we started our experment. Mine was this- first I got my materials, then I made a prediction, next I held up the two balls I was using to experiment with and made sure that they were eye level so it was a fair test. When I dropped them the ping pong ball went higher than the soft soccer ball. My prediction was wrong. Lastly I recorded my data.
