Scientific Method Review

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, the independent variable is ...

• The type of plant
• The amount of sunlight
• The type of music
• The type of liquid

• what is being measured

What is a factor that the experimenter has full control over and changes to see what happens?

• Dependent Variable
• Independent Variable
• Control group 
• Hypothesis

These are variables that are kept the same throughout all experimental groups to prevent error in the experiment.
