13. Why is the Scientific Method

an important process in doing
experiments?
A. It takes more work but it’s
worth it.
B. It helps the experiment to
take longer and be better.
C. It ensures that the results
can be trusted and repeated.
D. It ensures that the people
doing the experiments are
scientific.
14. What is the purpose of
doing multiple trials in an
experiment?
A. To get as much data as
possible.
B. To make sure the procedure
is done correctly every time.
C. Eliminate observations that
are not typical and reduce
errors.
D. To double-check the results
so they are the same each time.

to help you solve problems and
answer questions.
A. Experiment
B. Hypothesis
