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 object's 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 object's weight
does not affect how fast it falls.
