Ms. Canto performed an experiment with her class. She put one white flower into three different beakers (as shown in the muge below), in beaker 1, the placed 30 ml, of boiling water with a single drop of blue food coloring in beaker 2, the 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 I hour the 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?
Use A.C.E writing strategy to explain
The independent variable in Ms. Canto's experiment is the temperature of the water in the three different beakers. This is because it is the variable that is deliberately changed and manipulated by Ms. Canto. The dependent variable is the color of the white flower after one hour. This is the variable that is being measured and observed to see if there is any change as a result of the different temperatures of water.
The controlled variables in this experiment are the amount of water (30 mL) in each beaker, the type of food coloring used (blue), the type of flower used (white), the time the flower was left in the water (1 hour), and the conditions in which the experiment was conducted (such as room temperature). These variables are kept constant to ensure that any changes in the color of the flowers can be attributed to the temperature of the water and not to other factors.
Overall, the independent variable is the temperature of the water, the dependent variable is the color of the flower, and the controlled variables are the amount of water, type of food coloring, type of flower, time period, and experimental conditions.
