Summary

The three False Pass primary school students, Calum, Regan and Dayton Hoblet tested to see which kind of super ball would bounce the highest.

They found that a ball that was clear inside bounced the highest, while one that was lumpy did the worst. The opaque one was in the middle.

Question:

Are super balls all the same or are some better than others?

Which one is best?

Page 4: Bouncy Balls

Hypothesis:

The lumpy ball will bounce the lowest.

The clear ball will bounce the highest.

Page 5: Bouncy Balls

Research:

A ball picks up energy and speed as it falls. When it hits the ground it changes shape, stretches, and comes to a stop. Then the ball goes round again and this pushes the ball back up.

Materials:

Three different super balls: clear, cloudy and lumpy.

Ladder

Tape measure

Ruler

Tape

Page 7: Bouncy Balls

Procedure: (how to do something)

Drop each ball from 8 feet high three times and measure how high it bounces back.

Make a table and record the results.

Average the three results and compare them.

Graph the results

(See photo for setup)

Data:

Solid Clear Lumpy

1 5’ 1” = 61” 5’8”= 68” 4’3”= 51”

2 5’ = 60” 5’9”= 69” 4’4”= 52”

3 5’ = 60” 5’7”= 67” 4’4”= 52”

Total 181” 204” 155”

Average:(Total /3)

60 1/3” 68” 51 2/3”

The three super balls: clear, solid, and lumpy.

Page 14: Bouncy Balls

Summary of Results:

The clear ball bounced the highest all three times.

The lumpy ball bounced lowest all three times.

Hypothesis confirmed.

Page 15: Bouncy Balls

Conclusion:

Clear balls bounce the best, and lumpy balls bounce the worst.

Solid balls bounce in the middle.
