What are independent, dependent and constant variables in Squishy circuits project?
Hello,
The make it your own page has some hints:

One possible independent variable is the salt concentration needed to make electricity flow. The dependent variable would then be the light turning on/off or the motor rotating.
This project seems to be mostly a demonstration.
Other possible variables:
The amount of material that still makes electrical contact.
How dry/old can it be and still make electrical contact.
Let us know if this helps and if you still have questions.
Good luck.
