How Does Temperature Affect The Temperature Of Basketball

This principle goal the scientific investigation was to see if changes in temperature expands the air inside of the basketball causing it to bounce higher. This experiment was decided by observations made while playing the sport basketball. It was observed that when a basketball is left in the sun and made warm, the ball bounces higher when dribbled than if left inside. Our assumed result was that an increase in temperature would cause an increase in air pressure causing the bounce of the basketball to increase. The independent variable was the temperature in which a basketball was in. The dependent variable was the bounce height of the basketball dropped from a height of 200cm. The variables that were kept constant and controlled were the basketball brand tested (Wilson), The temperature outside when the basketball was dropped, and the drop height used. The control group was the basketball kept at room temperature and the experimental group was the basketballs dropped when frozen and heated. To collect the data needed, three basketballs were dropped from a height of 200 cm five times each and the
When the basketball was placed in extreme cold, the bounce height noticeably lessened by an average of 10 cm. When the basketball placed in extremely hot water and heated, the bounce height increased from the room temperature basketball by an average of 10 cm. When the basketball was heated, the air molecules inside the ball start moving faster. These molecules now collide with more energy resulting in increased air pressure inside the ball. Causing the ball to bounce higher. This theory was thought of during the selection of the hypothesis. When the ball was cooled, the air molecules inside the ball contracted causing the air pressure to decrease. This is why the frozen ball bounced the least
