Bouncing Balls Noise

FREE Noise Meter The more noise the more the balls bounce. Challenge your students to get the balls to remain completely still! Cool visual and positively reinforcing!

What makes a ball bouncy? Have you ever wondered why some balls bounce higher than others? A ball’s ability to bounce has a lot to do with its elasticity. So what is elasticity? It’s an object’s ability to return to its original shape after being stretched or squeezed.

Objects that are more stretchy are usually more elastic, too. Do you have pajama pants with elastic material in the top? You can stretch to get into them, but they will shrink back to fit your waist!In this science fair project, we’ll investigate bouncing ball physics to determine which ball has the highest elasticity and find out how elasticity contributes to bounce height. Spartan total warrior gamecube. Problem:Which of the following balls has the highest elasticity: a rubber ball, a marble, or a ping pong ball? Materials. Wooden board (a cutting board or a piece of scrap plywood will work great).

Yardstick, meter stick or tape measure with centimeters. Rubber bouncy ball. Marble. Ping pong ball. Table or wall. TapeProcedure:. Set the wooden board flat on the ground next to a wall or table.

Tape the meter stick to the wall or table as shown. Make sure that the meter stick starts with 0 is at the bottom.

Before conducting this experiment, use this time to formulate your hypothesis. Which ball do you think will bounce the highest?. Have a partner drop the rubber ball from the 25 centimeter mark and record the height of the first bounce in a table like the one below. Repeat 5 times and record bounce height for each of your 5 trials. It’s important to drop the ball and not throw it downward.

Average the recorded bounce heights from each trial together to find the average bounce height for the rubber ball. Here’s how to calculate an average. Disclaimer and Safety PrecautionsEducation.com provides the Science Fair Project Ideas for informationalpurposes only.
