I'm in 7th grade and I'm doing a science fair project on Lactose intolerance. The teacher wants us to list what our dependent and independent variables are. Firstly, i dont know what that means. Secondly, what are they for this project?

Thanks SOOOOOOOOOOOO much!!!What is the independent variable and the dependent variable?
A dependent variable changes when the independent variable changes like
Teen driving causes more Car crashes, but car crashes don't cause teen driving
The dependent variable: car crashes
The independent variable: how many teens drive
