science fair topic..?

Question

my teacher is REALLLLLLY strict.
I'm in advanced 7th grade
she's one of the science fair judges so i need a really good topic.
I'm in advanced and it can't be the molds, mildew, etc or anything with a vertebrae.
oh and she said ORIGINAL nothing with which grows better with plant rock or classical music?

I'm really interested in chemistry kind of things..

I know I really should be thinking of this on my own, but a little help won't hurt.

Thank You :)

I'm most intrested in

i accidentally put "i am more interested in" after Thank You...


also it's a first come first serve thing.. no one in the same period can have the same class...something that's not TOO hard but advanced for my age would be great so I can impress my new teacher..which I don't think she likes me very much :S

Answer 1

You could study measurement of pH. Very carefully make some standard solutions, calculate the pH, then compare the accuracy of various methods: litmus paper, indicators, titration, potentiometric titration (that's the one I did), and how much their accuracy changes in the presence of buffering. Take some of your standard solutions to a professional laboratory, tell them what you're doing, and ask them to let you run the tests. You'll probably still have to pay for the test, but most people in science would love to help you out.

That's only one example, but it could help stimulate some ideas of your own.

Answer 2

Its simple yet complex: water. Do something about its special properties, its dipole molecules,, hydrogen bonding, solvent properties, etc.

Answer 3

I always see in american movies that there's always a student that makes the potatoe stuff...

Answer 4

research bioluminesance in bacteria ...that would impress her
