Seawater composition, soft drink composition etc. You can do almost anything provided you have the right stuff to do precise measurements with.

Uh... the beach where there is seawater? If you do not have a precise electronic balance, I suggest you get one from somewhere. Two decimal places might not be precise enough to get good results, so try get one with as many places as you can.

the beach is pretty far for me ; so thats out ; anything else please ?

I already said the soft drink, in fact, my class is doing that right now, and it's a perfectly viable option. If you really want to to seawater, then just get a container, fill it with water, chuck in an unknown amount of NaCl and some sand/dirt/dead seaweed. Then do the gravimetric analysis, since you're going to get the same stuff if you do it with seawater. If you seriously have trouble coming up with an idea, talk to you teacher about it. Google is also your friend.

It's good to use your brain every once in a while =/ What do you think can be taken out without much effort on your part? What comes out when you open the can? We can't be answering every question you have, it's not good for you in the long run xD
