Independent Variable (IV): The part of the experiment that you are changing in order to test your hypothesis. Dependent Variable (DV): The part of the experiment that we are measuring (that is DEPENDENT on the other variable) Controls: Anything in the experiment that we do not change. We keep it constant for the purpose of the experiment.
A hypothesis “If (independent variable), then (dependent variable).” Here is an example of a hypothesis: If the temperature of sea water increases, then the amount of salt that dissolves in the water increases.
Independent Variable: Temperature of Water Dependent Variable: Egg Cook Time Control: 1Tbsp salt is added to the water at each temperature Hypothesis: If the water temperature is higher then the eggs will cook faster.
