• dependent variable

• independent variable

• controlled variable

• inferences

The effect being measured during the experiment.

Conditions that will remain the same during your experiment

• Independent Variable

• Dependent Variable

• Constant

• Control

The group that serves as a basis of comparison; this group is not exposed to the independent variable.

• experimental group

• control group

• data

• variables

This group is exposed to the independent variable.

What is a hypothesis?

• A statement offering a possible explanation for some observation that serves as a starting point for further investigation. Written as an "if ____, then ____."

• An untestable statement

• Whatever the teacher tells you is the truth

• An experiment

In an experiment designed to test Claim 1 on your study guide, what would be the hypothesis?

• If a plant is grown under red light, then it will grow taller than a plant under natural light.

• If a plant is grown under natural light, then it will grow taller than a plan under red light

In an experiment designed to test Claim 1 on your study guide, what would be the independent variable?

• red light

• natural light

• plant growth

In an experiment designed to test Claim 1 on your study guide, what would be the dependent variable?

• plant height

• red light

• natural light

In an experiment designed to test Claim 1 on your study guide, what would be the control group?

• plant grown under natural light

• plant grown under red light
