How well do disinfectants work?

[student & mom of 5]

Hello,
I'm in college, but there was no option for college students to ask questions! I'm doing my microbiology lab experiment from one of the choices from your web site: How well do disinfectants work? My question is for this project, what is my independent, dependent, and controlled variables? I don't know why I always struggle to understand these concepts! Any input I would greatly appreciate!
Thank you

Hi,

Here is the resource from the Science Buddies Project Guide on variables which may help:

You might find other parts of the project guide will help as well - here is the link to the complete guide:

Good luck!
