  1. The Bouncing Ball By: Will Schubert

  2. Problem • Determine how the height you drop a ball from affects the height the ball bounces back up.

  3. Independent Variable • The independent variable was the height

  4. Dependent Variable • The dependent variable was the height the ball bounces back up

  5. Constant Variables • The constants were- the bouncy ball, and the area I drop it from.

  6. Hypothesis • The higher I drop it from, the higher the ball will bounce.

  7. Control Group • My control group was 1 meter.

  8. Procedures • Obtain materials. • Create your tables for each group at each drop for a total of three tables. • Label each ball--- 1,2,3 • Tape 6 sheets of paper together, end to end. • Mark lines that cross the paper at the 50,100,200 cm marks. • Tape the paper to a wall so that the bottom is touching the ground. • Stand a meter stick against the wall in front of the paper , with the 0 cm end on the ground. • Person #1 is going drop the first ball from the 100 cm mark. • Person #2 will observe its bounce height • Person #2 will put his fingers on the paper at the height of the bounce, and make a mark to show the location • Person #1 will measure the height of the first bounce and record it on the data table. • Repeat the steps 8 through 11 2 more times from the 100 meter mark for trials 2 and 3 • Repeat steps 7 through 12 by using the drop height of 50 cm. • Repeat steps 7 through 12 by using the drop height of 200 cm • Use the calculator and figure the average bounce height for each ball in each of the trials. • Use the calculator and the total average bounce height for each table

  9. Materials • 1 meter stick • 3 of the same kinds of balls • 1 pencil • 1 calculator • 9 sheets of paper • 1 roll of tape

  10. My Results

  11. Conclusion • In conclusion the balls dropped from 2 meters bounced back up the highest

  12. How I could improve this experiment • I could improve this experiment by using different types of balls such as bouncy balls and soccer balls. I could have also used different heights to drop the balls from.

  13. Possible errors • Some possible errors I could have had are not correctly measuring the height that the ball bounced to the exact cm. • Dropping the balls with the same amount of force.
