Maria wants to know if birds prefer to eat in one place or another. She makes 3 feeders out of 2-L bottles and paints them all red. She fills each feeder 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 one feeder in a large dead tree, another rests on the dog house, and the last sits in a small bush. What is a constant variable in her experiment?
type of bird seed
amount of bird seed eaten
location of bird feeder
Nick wanted to see how high an ice cube would float in different temperatures of water. Identify the dependent variable.

the size of the ice cube
the amount of water
the temperature the ice cube was at its greatest height

An experiment is performed on plants to see how different liquids affect flower production. Each plant in the experiment is given a different liquid: water, apple juice, or milk. Each plant has the same amount of soil; same amount of sunlight, and the same amount of liquid. In this investigation, what is the independent variable?
the different liquids added
the amount of flowers produced
the type of plant used
the amount of sunlight

Jessie is concerned about how tired his classmates seem. He created a drink that he thinks will boost their energy. He recruits 100 classmates with a history of tiredness. He has 50 of them drink his new special energy drink. The other 50 drink a beverage that looks like the special energy drink, but is just water and food coloring. Both groups were told that they were getting the special drink that would boost energy. After 2 hours, 30 classmates in the first group reported having more energy and 8 classmates in the second group reported having more energy.
Which is the control group?
the students drinking the water and food coloring
the students drinking the new special energy drink
