Quick and Easy Science Fair Projects

There are a lot of quick and easy science fair projects around these days. However, this is a kind of project that is in reality very simple, but it is also quite attractive and out of the ordinary. This particular project involves magnetism. You just need to arrange for the magnets. The rest of the items are quite easily available. Look around the house and you will find plenty of them.

The ingredients needed for performing it are as follows:

- A few toy cars preferably four toy cars made of plastic.
- Donut magnets get double the number of donut magnets as the number of cars that are being used. In fact, the more magnets you use, the better the results are going to be.
- Elongated cardboard case, preferably the type used to hold tubelights.
- Cellophane tape and scissors.
- Thermocol.
- Colored paper and other toys for decorating the set-up.

The first step is to find out which poles of the donut magnets are similar poles by bringing each magnet close to one magnet set as a standard. Once you have located the same pole in every donut magnet, fasten the magnets to the toy cars using cellophane tape in such a way that the same poles face outward.

Now for the tracks make a latitudinal section of the cardboard case. Only one half shall be used for the experiment. It should have the same width as that of the toy cars, and be around a couple of meters in length. Now arrange them at a slight angle (approximately 3~5 degrees) to the horizontal plane using the thermocol. Attach a block of thermocol at the bottom as a dead end. At the top, leave around thirty centimeters of the track parallel to the horizontal plane. Line up the cars one by one. Place blocks of thermocol at regular intervals along the track in order to provide support to the entire set up. Also, make sure that the sides are vertical. Otherwise, the cars might fall over.

Now roll one car at a time to the track and release it. They will reach the bottom. However, adjacent cars would never touch due to the repulsive force created by the similar poles of the magnet, and you will observe a spring-like effect each time a car approaches the previous one.

This quick and easy science fair project can be decorated using the colored paper and toys. It illustrates the fact that the like poles of two magnets repel one another.
