Just confirming the variable here would be ice cream and the yogurt?
Thank you

- Project Question: Scientific Method - we are having a problem figuring out the Variable in our experiment - we are testing which has more bacteria, a shopping cart handle or a shopping cart seat? We think the Independent variable would be the seat and also the handles. We are not sure on the Dependent or Control...any help would be appreciated.
Thank you - Project Due Date: December

Hi itsavy!
In a science fair project, there are three different kinds of variables. These are the independent, dependent, and controlled variables. The independent variable is the thing that you change- in this case, the type of food that's melting. Ice cream and frozen yogurt aren't actually the variables; they're materials.
The dependent variable is what you measure- in this case, the time it takes to melt. The dependent variable depends on the independent variable!
The controlled variables are things that you don't change at all- there are lots of these! For example, you wouldn't want to change the starting temperature- that might change the time it takes to melt. And you wouldn't want to change anything else, like the amount of ice cream/frozen yogurt that you're melting. That could change your results too.
I would also suggest looking here: http://www.sciencebuddies.org/science-fair-projects/project_variables.shtml
Good luck with your project!
