In this experiment, the dependent variable is the change in water temperature. This is what the students are measuring to determine the effectiveness of the different materials (wool, cotton, and nylon) as insulators. The other options, such as the amount of time waited and the material of the socks, are independent variables or controlled variables rather than dependent variables.
Science Scenario for Variables.
Cold Feet
it is January and Maley, Sarah, and Becky are tired of having cold feet while waiting for the school bus to come in the moming. They decide to design an experiment to test the effectiveness of wool, cotton, and nylon as insulators. They fill Identical bottles with 200 ml of water at 100 C and place inside each sock. They take the temperature of the water after 20 minutes.
