Im doing an experimant on electrolysis of water. But my experimant does not have an independent variable cause im not changing anything..? So is it required to have an independent variable.Does every experiment have to have an independent variable?
Experiments involve observing/measuring dependent variables, therefore there have to be independent variables. Even though you aren't changing something, it doesn't mean that something can't be changed. Is this really an experiment that you're doing or are you just trying to create something?
