Actually i got some ideas including adding a weight inside the can so that the weight will bring the can to rotate forward.However it is only for a short distance. I need the can to move up an inclined plane for a considerable distance and most importantly it must be able to move on its own and must be related to mechanics. In addition, this project only limit us to use simple materials. So to all the physicist out there..please help out my little poor soul here...thanks a million....remember to provide as much details as possible...

Well, you could probably make a can climb a slope if you use a pretty wide can. Then, center a simple rod from end to end, attach a string to your "axle", and attach a relatively flat, heavy weight such as a washer to the string. Spin the can in your hand to wind it up till the weight is near the axle. Set it down, and let go. As the weight drops, it will spin the axle, driving the can forward.
The trick is, the axle diameter must be enough so that as the weight drops, it will drop faster than the can climbs the hill. Otherwise, it won't work. But its a simple design so you could play with it some to get the can/axle ratio right. Also, the can diameter will obviously need to be MUCH wider than the height you have to climb, as the weight can never drop below the elevation you have to climb. Good luck.

Well.. all the best for your Nobel Prize nomination.. I'll definitely be one of those cheering for you when you win it..
Anti-gravity can.. simple materials.. Anything else??? How about a teleporting machine while we're at it???
Coming to a more serious note, I appreciate your ambition. Try doing it for your Phd. But for your physics project, think of something more simple.
For starters, you could try getting an iron/steel ball to be suspended between a few strong electromagnets. Something along the lines of what you want to do, but a little more realistic.
You could buy a ball bearing from a cycle repair shop, and making electromagnets is easy. But you'll have to be very accurate about where and how you place the magnets and the ball..
All the best.

Make a track that has free fall on one end and a slope on the other. So bascially, you release a small car from the end of the free fall and with the the kinetic energy that is gains moving down it would be able to climb up a slope to a certain distance.
Of course, you have to make the free fall slope steeper and longer than the anti-gravity slope since there will be some energy losses due to friction. I will leave the calculation to you. Just remember that your free fall slope should be higher and steeper than the anti-gravity slope.

Sorry, but I don't get it.
You say the can must be able to move on it's own, meaning what? Nothing inside of it or outside of it interacting with it to make it roll uphill?
Otherwise, I'd just say put a small RC car inside the can facing straight up a small incline and press forward on the remote and watch as the can goes uphill... very very slight incline though.

Invent an anti-gravity machine.

i think it has already been done, on the discovery chanel they show a plane that free falls a certain speed and the people in the hull float. Or if my advise isn't good seek advise from NASA
