PLS HELP 1. Summarize the steps of the scientific method. What is the purpose of the control in an experiment? The variable?

You make an observation, ask a question, form a hypothesis, make a prediction about the hypothesis, test the prediction and lastly use the results to make new hypotheses or predictions.

This increases the reliability of the results (A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable)

The things that are changing in an experiment are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types.
