HypothesisHypothesis

Make an If…then… statement.

ExperimentExperiment

You must identify and control the variables.

If…I.V.…then…D.V.…◦Independent variable - Cause◦Dependent variable - Effect

You need two groups to compare results.◦Control Group – does not get the I.V.◦Experimental Group – gets the I.V.

Collect some data.
