An experiment is conducted 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, what are the controlled variables?

• Type of plant, amount of music and sunlight

• Water, apple juice, milk

• Plant growth
