Answer

  1. Measure the height from which the cupcake cases are dropped using a metre rule, ensuring to keep the height constant for all trials.
  2. Drop different numbers of cupcake cases into the stack.
  3. For each drop, record the time taken for the stack of cupcake cases to reach the ground.
  4. Repeat the experiment with varying numbers of cupcake cases and average the time taken for each trial.
  5. Finally, plot a graph of speed of fall against the number of cupcake cases dropped.
