Question 14
Investigate how parachute surface area affects air resistance. Use two plastic squares, 30 × 30 cm and 60 × 60 cm, with four 30 cm strings attached to the corners of each and an identical small weight attached to each set of strings. Hold the parachutes at the same height and release them at the same time without pushing. Observe which reaches the ground first; swap observer and releaser roles and repeat. Use a safe, teacher-approved release position; do not climb on unstable furniture.
On the count of three, drop both parachutes at the same time. Your classmate observes which parachute reaches the ground first and records the results. Swap roles. Then repeat the experiment until you have recorded enough results to have a clear conclusion.
