Pre-Lab Questions
1. In your own words, explain what the scientific method is.
Scientific methods are methodical ways utilized by scientists to study natural occurrences. It
entails gathering information, developing theories, running experiments, evaluating the results,
and coming to judgments.

2. In your own words, explain what a hypothesis is.
A hypothesis is an explanation or prediction that can be verified by observation or
experimentation. It is a provisional assertion that raises the possibility of a relationship between
variables or events.

3. When conducting experiments, scientists often conduct repeated trials of the experiment. Why
do you think repeated trials are conducted in experiments?
Experiments with repeated trials are more likely to yield reliable, precise, and repeatable
results. Researchers can lower random error, improve precision, identify patterns or trends, and
evaluate repeatability by carrying out many trials. This strengthens the reliability and validity of
scientific discoveries.

4. For each of the following statements, select whether you can or cannot test it by using the
scientific method:

a. Are there more seeds in a medium sized Red Delicious Apple or a medium size Green
Granny Smith Apple?
