Nick wanted to see how high an ice cube would float in different temperatures of water. Identify the independent variable. A. size of ice cube
B. amount of water
C. temperature the ice cube was at its' highest height
D. height of ice cube
E. temperature of water

E. temperature of the water

Explanation:

The independent variable is the variable that changes, and it's also the variable that the dependent variable's results depend on. So depending on the temperature of the water, results in the ice cubes height. So the independent variable is the temperature of the water.
