OK here's one.
Get live fertilized fish eggs from the same fish.
Randomly divide them equally into five separate groups.
Put each group of eggs into its own container of stream, ocean, lake,... water consistent with the type of water the eggs could live in.
Add some known (or unknown) pollutant to each of four containers. But add increased measures of the same pollutant so that each polluted container has different concentrations of pollution. Keep the fifth container as the control container totally free of the pollutant.
Mother the fish eggs as best you can to keep them alive in all five containers. You can go on line to find out how to take care of fish eggs.
When the fry are hatched (fry is what baby fish are called), count them in each container. Then graph the number of hatched fry against the concentration of pollutant put in each container.
Your thesis would be: The greatest number of hatched fry will be in the container without the pollutant. The least number will be from the container with the most pollutant. You should be able to make a nice graph of number of hatched fry versus the concentration of pollutant.

maybe she can do one about what different pollutants kill fish, for example, bleach, milk, olive oil, etc...
hope i helped!
its totally off the subject but i just finished up my science fair and i got 1st place at my school, 1st place at state, and i am going on to city. i did it on spice aromas and bacteria-if spice aromas were bacteria inhibitors. its a really interesting project and fun to do!

Maybe the effect of the density of the polutant (more/less than that of water)'s effect on its degree of devastation.
(Oil floats on water, as it has a lower density. Compare something like that to a polutant that sinks and has a higher denisty).
