science in room 16

About three weeks ago room 15 went to room 16 for science.For our experiment we were learning how moon craters are formed so we got given a big tray of flour,a 1 meter long ruler,a 30 centimeter long ruler,a golf ball ,a tennis ball and a ping pong ball.Then we had to drop each of the balls from 10 centimeters,50 centimeters and 100 centimeters.After we did that,one of us had to write down how wide and how deep the crater was from the golf ball, the tennis ball and the ping pong ball.When we got the results, the golf ball had the deepest craters because it was such a heavy ball, the tennis ball was not far off but it was alot wider and the ping pong ball was completly smaller then the other balls.When we were finished all of us were completly covered with flour.
