Science Buddies: "Ask an Expert"

whats a variable?

A varaible is something that can affect the results of your experiement. A CONTROLLED VARIABLE is one that is kept constant throughout your experiment. A EXPERIMENTAL VARIABLE is the thing that you change. For more specifics, I need to know more about your project.

Hope this helps!
