Question

Ms. Canto performed an experiment with her class. She put one whute flower into three different beakers (as shown in the image below). In beaker 1, she placed 30mL of boiling water with a single drop of blue food coloring l. 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 if cold water with a single drop of blue food coloring. Afetr one 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?

Answer 1

The independent variable in this experiment is the temperature of the water (boiling, room temperature, and cold).

The dependent variable is the color change of the white flower after one hour.

The controlled variables are the type of flower used, the amount of water (30 mL) in each beaker, the amount of food coloring (one drop) in each beaker, the type of food coloring, and the time the flower was left in the water (one hour).
