I have a science fair coming up and i need idea so plz help!?

Question

i need a couple of nice topics! i am in 10th grade so plz help i am up for a little challenge i love science

Answer 1

you can try out all sorts of things.

a future power plant powered by the dark energy which scientists say is causing our universe to expand. Be creative, imaginative, add some advantages and disadvantages to it.

regards, hope it helped

Answer 2

What kind of science specialty are you most interested in?  My suggestion is that you find a project that you will be able to understand thoroughly.  The two things that make the biggest impression are:

1.  Has the student done a careful job carrying out the steps of her experiment?

2.  Is the student able to explain (with some conviction) what each part of the experiment means, and what the implications are?

For some project ideas, most any of these will give you a great opportunuty to excel:

Find a project that you feel comfortable with, and make it your goal to know it inside and out.

Good luck!

Answer 3

You could show the different levels of conductivity in fluids.

Water for example if pure, actually doesn't conduct electricity. Only when it is "tainted" does it conduct. You could start with pure distilled water with an ohm meter in it to show that there is no conductivity. You can then have a beaker of common tap water and show the level of conductivity in it. The minerals and salts are what increase the conductivity. You could do other liquids also like bleach and rubbing alcohol to show their levels of conductivity.

I guarantee that the majority of the population doesn't know that pure water doesn't conduct electricity and I doubt most teachers know that fact.

The container must be cleaned with alcohol and the water must be pure distilled water and the container must then be sealed to prevent contamination from airborne dust and pollutants. Even the oil on one fingerprint will change the water from non-conductive to conductive.

The other beakers won't matter if they are covered or not since they will already conduct electricity.
