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?

The independent variable in Ms. Canto's experiment is the temperature of the water (boiling, room temperature, cold). The dependent variable is the color change of the white flower. The controlled variables are the type of flower used, the amount of water (30 mL), the presence of food coloring, the time the flower was left in the water (1 hour), and the size of the beakers. By controlling these variables, Ms. Canto can isolate the effect of water temperature on the color change of the flower.
Make smaller and use ten year old words
The thing Ms. Canto changed on purpose in her experiment was the water temperature. The thing she was looking to see change because of that was the color of the flower. The things that stayed the same in the experiment were the kind of flower used, the amount of water in each beaker, the food coloring added, how long the flower was in the water, and the size of the beakers. By keeping these things the same, Ms. Canto could figure out if water temperature affected the color of the flower.
Make that way shorter
Ms. Canto changed the water temperature to see if it would change the flower's color. She kept everything else the same to make sure any color change was because of the temperature.
