What are Variables?

The fifth grade has just started a unit on variables, which is important to understand when undertaking any scientific experiment. A variable is any "thing" that might change or be changed in any experiment. Three are three types of variables:

Independent Variable: The variable you intentionally change or test. It's what you're curious about.
Dependent Variable: The variable that you observe and/or measure. It's the variable affected by the independent variable.
Controlled or Constant Variables: All the other variables. These are the variables that remain the same throughout the investigation. You do not change them.
