Science fair project variables

[deleted-313391]

Hello!
My son will be performing the sprouting sweet potato slips experiment and the teacher is asking him to identify the test and outcome variables. Can someone explain us what is she asking for?
Thanks in advance

Hello. This will be a fun experiment.

Your son will set up sweet potatoes in different ways in order to see if this difference has an effect on the outcome. These changes are the test variables. The outcome variable is simply what he will be measuring as a result of the
experiment.

Another way to phrase these variables are controlled, independent, and dependent variables. More discussion can be found here:
https://www.sciencebuddies.org/science- ... bles.shtml

Controlled variable: settings you wish to keep constant in your experiment so that it doesn't affect the outcome
Independent variable: settings which you, as the scientist, change in order to see how it affects the outcome of your experiment
Dependent variable: what you measure to determine whether it is affected by your independent variable(s)

Based on these definitions, what do you think your variables are? Take a crack at it and write back with what you think.

Good luck!
