The very idea of conducting a science fair is to help the students learn scientific facts in an interesting way, to understand it and also exhibit what they had learned, to an audience. To achieve this, the theme of the project must be within the realm of the students and has to be chosen carefully. In order to have a successful project, one must first find a good science fair project idea.
Good school libraries and well equipped public libraries should be a helpful source for good science fair project ideas. But now plenty are available over the Internet. One can get a good science fair project idea from the ones listed, according to the targeted age group. In the science category, choose a topic that interests most of the students. Then, narrow it down and make it into a project. It would be ideal if it can be of some use to the general public also. In general, use the internet sparingly, unless there is a paid guide. Keep in mind that all of the ideas and information you find for free on the internet are about projects that have been done before by thousands of other students, while in general, paid guides are performed by far fewer students because of the price tag barrier.
A good science fair project idea can be chosen from natural science, physical science, microbiology or any interesting branch of science. Be considerate that the necessary articles required for the project are freely available either naturally or in the nearby areas. Let not the collection of materials be a big chore for the eager students that the project becomes a hard task.
Safety should be high on the list such that the students understand the risks involved and the project is undertaken in such a way that it is monitored and supervised both in the school and if it is carried on at home, by some elder.
It would be ideal if the project be done and over within a few minutes time, such that it can be demonstrated in full to the sentences and the audience, who attend the fair. Time consuming projects can make the tiny minds restless.
Bigger projects that need checking and validation may be reserved for the students of the higher grades. Simple projects should be easily reproducible. Little projects that have a public value may be highly appreciated, and should definitely be considered good science fair project ideas if they have wide application. Few natural cycles that take a few days to complete may be carefully conducted such that the audiences may be asked to revisit the fair, which may be a crowed puller project.
Explanation of simple magical tricks and attempts to demystifying existing myths may be quiet receptive to the young minds. For zoology projects, information is collected by observation. For physics and chemistry projects, experiments are done, data is collected and the conclusions are made. Such should be the good science fair project ideas.
Good science fair project ideas and the projects should keep the young minds motivated.
