  • 1 bouncy ball with a diameter of 1.5 inches
  • 1 stress ball with a diameter of 2 inches
  • 1 tennis ball with a diameter of 2.5 inches
  • 1 twelve inch ruler
  • 1 piece of tape
  • 1 wall/table/chair/etc.
  • 1 wood deck/porch

  • Use the ruler to measure twelve inches/one foot off the ground
  • Cut the tape 
  • Use the tape to mark the twelve-inches-off-the-ground spot
  • Hold the bouncy ball up to the tape
  • Let go
  • Record number of bounces after the ball has started to roll
  • Repeat three times
  • Hold the stress ball up to the piece of tape
  • Let go
  • Record number of bounces after the ball has started to roll
  • Hold the tennis ball up to the tape
  •  Let go
  •  Record number of bounces after the ball has started to roll

The bouncy ball had the highest average bounces. During my experiment, the balls bounced on an uneven wood board, causing the ball to roll. In the future, I will make sure that the material that I bounce my ball on is smooth. It would be interesting to see how different materials on the same ball affect the way it bounces or the number of bounces that are caused.]]> 2018-06-11 13:13:52 UTC https://padlet.com/cc54728/biiuh2sjljfw/wish/266607340 Purpose cc54728 https://padlet.com/cc54728/biiuh2sjljfw/wish/266607341 I want to find out which ball causes the most bounces]]> 2018-06-11 13:13:52 UTC https://padlet.com/cc54728/biiuh2sjljfw/wish/266607341 Materials cc54728 https://padlet.com/cc54728/biiuh2sjljfw/wish/266609816 2018-06-11 13:23:51 UTC https://padlet.com/cc54728/biiuh2sjljfw/wish/266609816 Video of procedure cc54728 https://padlet.com/cc54728/biiuh2sjljfw/wish/266611889 2018-06-11 13:32:17 UTC https://padlet.com/cc54728/biiuh2sjljfw/wish/266611889 What Your Set Up Should Look Like cc54728 https://padlet.com/cc54728/biiuh2sjljfw/wish/266817548 2018-06-12 13:32:56 UTC https://padlet.com/cc54728/biiuh2sjljfw/wish/266817548
