A logical and orderly method used to solve

problems.

All branches of science attempt to understand the universe by using the

6 Steps of the Scientific Method

Hypothesis

an educated guess.

Vocabulary:

Variable:anything that

varies (changes) in an experiment.

Vocabulary:

Manipulated Variable:

the variable that is deliberately
