Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, what are the constant variables?
Type of plant, amount of music, and sunlight
Water, apple juice, milk
Plant growth

The height the ball bounces
Height of the ball being dropped
The first time the ball is dropped

Maria wants to know if birds prefer to eat in one place over another. She makes three feeders out of 2-liter bottles and paints all of them red. She fills each of the feeders with the same amount of mixed birdseed, and plans to keep the feeders out for 10 days before measuring how much seed is eaten from each feeder. She puts each of the feeders in her back yard: one feeder in a large dead tree, another feeder she sits on the dog house, and the last she sits in a small bushy tree.
What is the constant variable?
Location of bird feeder
Amount of birdseed eaten
Type of birdseed
What is the dependent variable?
