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 research, what are the constant variables?

• Type of plant, amount of music and sunlight

• Water, apple juice, milk

• Plant growth
