School Science Projects

Me and my buddy Mariah are doing a science fair for school. We need to know what we could use for the hypothesis,(An educated guess) The question is will a strawberry rot faster then a blackberry in 4 days.

I wantewd to do something like how long does it take bleach to kill a plant, but that was already taken. Any ideas on similar projects that would not be TOO similar?

Any science fair ideas? Ideas or websites beside Science buddies.org

My science project is due on somewhere on the beginning of Janurary. I thought of an idea and my science buddies did too but they got rejected. (I hope it wasn’t taken, too, or else I can’t do it w/ my partners) I thought of one, too, but they are trying again as well. Well the project is about the plant that is over populated w/ other seeds, but of the same kind. I think other plants will do well so the project can be a better. We need to see how they will grow, how they react to the over populated area.

The plants I need, need to be grown in which you can see whatever leaves it has, the height, width, et cetera.

The control is the one that is being grown with space. The variable is the one being grown w/ more, of course, population density.
I also need to know how long will they grow.
