Can you please help with identifying the independent, dependent and controlled variables?
thank you

Hi Catherineb99,

Welcome to the Ask An Expert forums. We're here to help you, but we won't do all the work for you . So, use the article I link to and my tips to try to figure our your independent, dependent, and controlled variables for yourself. Post back with what you think each of those variables is, and I'll give some specific feedback at that point.

Science Buddies has a great article about identifying your variables. Check it out here: https://www.sciencebuddies.org/science- ... bles.shtml. Make sure to check out the "Examples" tab.

In my own words, the independent variable is the thing YOU change. The dependent variable (sometimes called the response variable) is what changes in response to the changes you make to the independent variable. Controlled variables are the things you keep the same from experiment to experiment.

Take a whirl at identifying your different variables, post back with what you think they are, and we'll go from there.
