I create an experiment to measure which brand of sponge can absorb the most water. I use 3 different brands of sponge, 3 of the same beakers filled with 30 mL of water from the faucet at room temperature. What is the independent, dependent, and control variable. Select 3 options.

What is a constant/control in an experiment?

• Things that do not change in a experiment. It's the variable that stays the same. You can have many variables stay the same.
