Science fair !!! HELP!!?

Question

i need a science fair idea withan experiment for the idea (3-D display diamention)

Answer 1

Holograms: the best idea if you can afford to create.

Answer 2

Here's hoping that you get some real scentists judgeing your exhibits instead of morons who haven't a clue what the scientific proceedure is all about, and expect your exhibit to prove something when all science really does is disprove existing theories.

If so, try to prove or disprove the thoery that human faces are symmetrical,

or that brain size = potential for intelligence,

or that the sky is blue.

If you are a true scientist, and have a working knowledge of the scientific process, you will be able to come up with your own experiments for all three of my ideas.

Answer 3

This is simple but actually this technology is saving lives in third world countries. Its a water filter used to make water more drinkable. This is very relavent socially; i.e., if nobody else has the idea they will like the benefit to humanity idea. Especially if your write up talks about all the drinking water related diseases that are preventable.

The easiest filter design I could find is this one. It should do
for science fair project.

Not sure what grade you're in, but here's something I did in elementary school:

Drop a raw egg from different heights on a ladder and compare the sizes of the splatters of the eggs based on height on the ladder. I think I titled my board "All Cracked Up". Good luck! :)
