What is are the dependant variables & independant variables, and controlled variables in thi science experimen?

im investigating and observing whether different colours are equally visible in the dark.


im using coloured paper and the dial on my light switch to adjust the brightness %26amp; dimness. umm im also using people in my family to determine what they see for the results


thanks. :)What is are the dependant variables %26amp; independant variables, and controlled variables in thi science experimen?
The independent is the lights vs. dark because your controlling that to see its effect on the dependent variable, which in your case is the visibility of the colors in light vs. dark.
