Hypothesis = a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
Theory = a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation. It is a misconception that theories turn into laws with enough research.

3. Scientific Method Vocabulary
Control = a person, group, event, etc., that is used as a constant and unchanging standard of comparison in scientific experimentation.
Independent Variable = a variable that is manipulated or changed by the scientist.

4. Scientific Method Vocabulary
Dependent Variable = a variable that is observed or measured in the experiment, and it is known as the dependent variable.
