Once you have picked a topic and made a hypothesis that you wish to test for your science project you need to begin your research. The background research that you put into your project can make a world of a difference to the quality of project you finally end up with.

By writing a comprehensive background research plan you will save yourself considerable time and effort. This research will help you identify the techniques and the equipment that you can use in the topic that your science fair project is based on.

The actual reading you do during the research phase will also give you a better idea of the theory behind the topic that you have chosen for the hypothesis. It will allow you to make your prediction in the hypothesis better.

Another important part of research is networking with other people working on similar projects. You need to talk to others who are involved in experiments like the ones you are contemplating doing. Find out the practical problems that may crop up during the experiments and ask how they deal with them.

A general question does not lead to good research. Make your research questions as specific and graphic as possible.  That way you will probably have most of the answers even before you begin working on the actual science fair project.
