Wink

The possibilities are endless! Try browsing the forums, but here are a couple:
-make a solar-powered car
-see which fabric cleaners work the best

Good Luck!

Please narrow down the possibilities so that it becomes easier to help you out. Which of these (the ones's you mentioned) interests you the most?

The Newtons and friends were taking tea
Beneath the boughs of an apple tree,
When a falling fruit landed on the
Head of the head of the family.
Mrs. Newton cried, 'Well deary me!
That could've caused an injury'.
But clever Isaac alone could see,
The situation's true gravity.

Thumbs up Solar Powered Car

You can buy solar panels at hobby and science stores. They come with a few solar cells, and a pair of wires. Some even come with motors. The solar panel creates an electrical current. I can't remember if it is AC or DC. The current then goes through the wires to power the electric motor to spin. Simply attach two wheels using gears, or one wheel, and make sure that you have an axel that connects it to its brother wheel. Make sure the car is light-weight. You can build fairly light cars out of K'Nex, balsa wood, and even model kits. Just remember, the car must be light so that the small motor can actually move it. Don't make your car out of metal.

Lightbulb Best Physics Project

Usually the best physics project that I keep seeing getting high marks, are built-from-scratch trebuchets. They are like catapults, but they work differently. You can REALLY impress the judges if you build it precise enough to where you can launch your payload and hit a pre-designated target on the ground. I must warn you, building one of these IS NOT EASY.

The question asked was vague and I think thats the reason why we could help appropriately. So please ask us precise questions for precise answers!
