The purple “superball”:
The black sphere:

First: We will be taking both the black and purple sphere and dropping them from a distance of one meter about the ground.
Second: We will calculate the height of the rebound of both spheres once dropped.
Third: Repeat steps 1 and 2 three different times to be more precise on the out come.
Fourth: Soak the black sphere in hot water. Fifth: Re-drop the sphere and measure the
rebound of the black sphere again. Sixth: Keep track of all the data in a data table.

WHAT WILL HAPPEN WHEN WE DROP THE SPHERES?

Room Temp.
Trial #1 Trial #2 Trial #3 Average
Superball 24 in. 23.5 in. 23 in. 23.5 in.
Black Sphere #1
1 cm. 1 cm. 1 cm. 1 cm.
We will drop the superball and black sphere each three times from a height of one meter and record the height at which each rebounds.
*WHAT DO YOU NOTICE?Although the superball and the black sphere appear to be made out of the same material, the superball bounces significantly higher than the black sphere.

Hot .Water Temp
Trial #1 Trial #2 Trial #3
Black Sphere 2.5 in. 2 in. 1.5 in.
We will now place the black sphere in 200 mL of hot water for approximately two minutes and record the height of each rebound dropped from one meter.
*WHAT DO YOU NOTICE?The sphere bounces higher after being heated!

1: Why do you think the purple ball bounces higher then the black one?
2: What type of energy transfer occurs when the ball is being held at one meter above the ground?
3: What type of energy transfer occurs as the ball is being dropped?
4: What kind of energy transfer occurs when we heat up the black sphere?
5: What do you think will end up happening once we heat up the black sphere?
