minnie30567746 is truly a scientist!
Default Well

I would research the composition of those chemicals, and research the antomy of a common fish. If you can see what breakdown composes the chemical, maybe you can see if there is a recognizable chemical that is dangerous to any living organisms health.

They do pretty different things, but you're doing a research project, not an experiment, right? It would be hard to actually try to emulate a marine environment.

I'm not sure about motor oil, but pesticides are harmful because these harmful pesticides don't kill them, but stay in their muscle/fat, and slowly cause harmful effects. Research this. I think DDT was a common pesticide that often hurted birds, cause birds ate fish that had DDT inside them...

As for detergents, well, look what it does to your clothing... In a lake, it might cause a whole lake to die. You'll want to look that up, cause detergents contain a chemical that makes plants flourish. Plants flourish, then die, and get to the bottom of the lake. The plants decompose with bacteria, using up all the O2. No more O2, more dead fish and plants, more buildup-->no more lake. No more O2 for fish is really harmful.

As for all pollutants, it's bad to have in the water, cause imagine a fish surviving in 100% detergent--it's impossible.

Also, you might want to check out what these chemicals might do to the fishes gills. The best way to kill is fish is stop its O2 supply or its way to get O2.

I think it is extremely unlikely, almost impossible, that the sun will be able to have enough energy to cook something. Unless it's a really sunny day (ninety something degrees), and you make your a really black pan.

I believe that if one were to use a parabolic shell rather than a box shape, the sunlight energy could be focused to provide temperatures of the range from 75 to 125 degrees celsius.

Here are a few links to the construction procedures and application:

So it's not necessarily true that sunlight won't be able to cook food, just there needs to be a different way to apply it.
