Ms. Canto performed an experiment with her class. She put one white flower into three different beakers (as shown in the image below). In beaker 1, she placed 30 mL of boiling water with a single drop of blue food coloring. In beaker 2, she placed 30 mL of room temperature water with a single drop of blue food coloring. In beaker 3, she placed 30 mL of cold water with a single drop of blue food coloring. After 1 hour she checked the flowers to see if the color of the flowers had changed. What are the independent, dependent, and controlled variables in Ms, Canto's Class experiment?
Independent variable: Temperature of the water (boiling, room temperature, cold)
Dependent variable: Color change of the white flower
Controlled variables: Amount of water (30 mL), type of food coloring (blue), type of white flower, time (1 hour), size of beakers, amount of light, location of beakers
