Which Type of Orange Juice has the most Vitamin C?

Postby yehuol » Mon Oct 11, 2010 3:38 pm

Hi, my son has choose to do this project and he is having a hard time starting it, and i really dont have a clue on what to do either. He is being asked for a variable, a outcome variable and 10 constants. The variable would be the iodine and soluble starch and the outcome would be to know whch OJ has more vitamin C by doing the trituration. We need 10 constants that will remain the same but we are kind of confuse.

Thank you!

Hi yehuol,

What you're looking for are what we call the independent variable, dependent variable, and controlled variables. Lots of info and examples here:
