Question How does the temperature affect the bounce height of a ball ?

hypothesis I predict that the ball in room temperature will bounce the highest because it will be much lighter than the two in the refrigerator and the freezer. The two in the refrigerator and freezer will be to heavy to bounce as high as the room temperatures bounce height.

Materials 12 bouncy balls Freezer refrigerator Thermometer Ruler

procedures Gather the materials Set up the ruler Put the balls in the appropriate places : refrigerator,freezer,room Wait an hour to let the bouncy balls get used to their temperatures Take the bouncy balls out and start dropping them one at a time Do the same for the rest Record data

conclusion The bouncy ball at room temperature bounced the highest. Then the bouncy ball in the refrigerator bounced a little lower then the room temperature one.but of course the one in the freezer bounced pretty low. So the bouncy ball in the room temperature bounced higher then both the refrigerator and freezer bouncy balls.
