Question

read the description of a science experiment below. which part of the experiment is the third step in the scientific method (testing a hypothesis)? sarah wants to create an experiment to determine whether an objects weight determines how fast it will fall. she hopes to prove that heavier objects fall faster than lighter ones. she buys two weights that have the same size and shape. however, one is heavier than the other. she has her mother drop both weights at the same time from a window. to her surprise, the weights land at exactly the same time. she repeats the experiment several times, but the weights always hit the ground at the same time. sarah is forced to admit that she was wrong; an objects weight does not affect how fast it falls. a. \an objects weight does not affect how fast it falls.\ b. \she has her mother drop both weights at the same time from a window.\ c. \she hopes to prove that heavier objects fall faster than lighter ones.\ d. \sarah wants to create an experiment to determine whether an objects weight determines how fast it will fall.\

Explanation:

The scientific method steps include making an observation, forming a hypothesis, testing the hypothesis (usually through an experiment), analyzing the data, and drawing a conclusion. In Sarah's experiment, having her mother drop both weights at the same time from a window is the testing - hypothesis step. Option A is the conclusion, Option C is the hypothesis, and Option D is the problem statement.

Answer:

B. "She has her mother drop both weights at the same time from a window."
