An engineer wants to test the ability of certain materials to resist cracking. The objects she wants to test are provided. She drops a 500 g weight from a height of 100 cm on each tested material. She observes and records the results after each drop. How can she improve the experiment?

• Use weights of different masses to drop on each test material

• Drop the weight from a different height on each test material

• Use only test materials that are the same shape and thickness for each drop test

• Use a fewer number of test materials for the experiment
