a) Dropping it outside on a windy day might slow down the tennis ball falls. The wind will act as a resistance and will slow down the speed of the ball but it might be difficult to control the wind speed and direction for consistency.
b) Tying a parachute cut from a plastic bag might slow down the tennis ball falls by providing air resistance to the falling ball. This method can be effective if the parachute is appropriately designed and the strings are not too long.
c) Gluing two large feathers to the top of the ball might also slow down the tennis ball falls by increasing its air resistance. This method could be effective if the feathers are appropriately placed and the weight distribution of the ball is not affected.
d) Punching a few holes into the surface of the ball might not affect the rate of the tennis ball falls much. It might make the ball unstable during the fall and could cause it to fall faster.
Overall, B and C are the most effective methods for slowing down the rate of the tennis ball fall.
For science project Sarah has been instructed the test for different methods of slowing down the rate of tennis ball falls from 10 ft above the ground. She is working with Janice and Jose who are timing and recording the tennis ball drops.
