Narrow your topic.

Most often your first idea is too broad or general for a science fair investigation and will need to be narrowed down. A poor topic would be, "How Plants Grow." Consider "The Effect of Acid Rain on Bean Growth." This second topic is narrow enough to investigate.

The easiest way to narrow your topic is to learn more about it. The library is the place to get this information. An encyclopedia will provide general information. From this information the subject area of the card catalogue will be of more use. Use the library to learn enough about your subject so that you can define a specific problem.

It is not uncommon for a professional researcher to consult with his colleagues; you too should seek help when necessary. Other students, your teacher, parents, or even other experts can help you narrow your topic. Once a clear statement of your topic is complete, you can begin the real work of investigating.
