Aquatic plant science fair-minded experiment?
Answers: There a lot of variables that may be too diferent to properly try-out. I would ask your science teacher, she can discuss and plan near you better. Hope this helps!

adjectives plants are widely varied -- some plants do great within any conditions and some need an profusion of care (like profoundly of bright direct light and co2 injections -- which are expensive for a science project). substrate really doesn't thing a whole lot on graceful to grow plants that would make an inexpensive science experiment.
here is a great site if you want to try to come up next to a do-able project. one interesting plant is hygrophilia difformis (water wisteria) -- it is readily available and the palm leaf shape changes depending on the amount of buoyant and nutrients it gets.

put one within more soft water and one contained by more hard hose and see which plant grew the most
make sure the plant is one and the same size, type, gets impossible to tell apart light, sea parameters save for hardness, etc.
or you could save one in the dimness all the time and see if one dies... lol
lots and lots of option.
hope I helped! =]
Lots of relatives like to saline their aquariums, especially when their fish aren't doing too well. Maybe a bit than substrate, which might not make that big of a difference according to some other answers, you could try soundtrack the amount of salt concentration and how it affects which types of plants. Some may be better competent to tolerate more salt than others, and although most sources utter about .3% is adjectives a plant can handle, at hand are probably specific species that can't take it above .25% and others that could budge up to .6% or something. It would be good to find out! And, possibly you could find out, too, if once a plant has be "burned" by a too-high salting concentration surrounded by the water, if you can reverse the defile by moving the plant to a non-salted tank. Would freshly reducing the salt concentration to a previously tolerable rank be enough to put together the plant healthy again, or does it hold to go to 100% non-salted sea? Anyway, just some thoughts.
Hope this help. Good luck!
