Materials

The materials required for this experiment:

  • 5 boys and 5 girls aged 10
  • 5 boys and 5 girls aged 15
  • 1 ping pong ball
  • A stop watch
  • A flat floor surface
  • An assistant to time the experiment. 

Procedure

  1. For this experiment, the independent variable is the age and gender of the participant. The dependent variable is the number of times the ping pong ball is caught in one minute. This is determined by counting and using a stop watch to measure the time. The constants (control variables) are the surface of the floor, the time given to catch the ball and the type of ball used.
  2. The 1st participant is given the ping pong ball to hold in his/her right hand.
  3. The assistant starts the stop watch and instructs the participant to begin.
  4. The participant is to dribble the ball between both hands. Holding the ping pong ball in the right hand, drop the ping pong ball on the floor. When the ball bounces up, it is caught using the left hand. Repeat using the other hand.
  5. Count the number of time the participant drops and catches the ping pong ball.
  6. At the end of 1 minute, the assistant instructs the participant to stop. The number of times the ping pong ball is bounced is recorded in the table below.
  7. Repeat steps 2 to 6 for the remaining 19 boys and girls.
