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
Dependent variable means
the scientist controls what to test
educated guess
ask a question
what is being measured
