Forming a hypothesis is the first step of the scientific method.

True

False

A scientific law is different from a scientific theory because it describes something in nature without attempting to explain it.

True

False

In order for a hypothesis to be testable, scientists need to be able to carry out investigations that will either support or disprove.

True

The experimental group is the group that is left alone during the experiment.

True
