What is the purpose of a control variable in an experiment?

Back

Control variables are kept constant to ensure that any changes in the dependent variable are due to the independent variable.

Front

What axis on a graph represents the independent variable?

Back

The x-axis represents the independent variable.

Front

What axis on a graph represents the dependent variable?

If you are testing how different amounts of sunlight affect plant growth, what is the dependent variable?

Back

The growth of the plants.
