Variables
Variables that are kept the same to ensure only one factor is being tested. Several of these are present in a sound experiment.
Control variables
842 m. to km.
0.842 km.
First two steps in the scientific method.
1. Make an observation.
2. Formulate a hypothesis.

3rd and 4th step in the Scientific Method.
Design an experiment.
Analyze data.
