A well-organized science fair can be interesting and equally informative. The first step towards organizing a science fair is to choose a topic. The topic should be chosen according to one's field of interest. After having chosen a topic one should first get it approved by parents and teachers in order to avoid any unwanted problem at a later stage. Then the plan should be laid out and the materials required should be collected.

Some tips to find a science fair topic idea easily are to look at the different categories of science and choose a good idea. You can also search current events to find ideas, or observe the small things in day-to-day life which may provide inspiration. You could search through science journals and magazines, or watch the Discovery Channel for ideas. Alternatively, the internet is becoming a great source of inspiration, though one must be careful when choosing a science fair topic idea from the internet. Too many people using the same science fair topic ideas is bad news for the students who want to be the winners of the science fair.

Science project topic ideas can be related to any branch of science namely physical, chemical, biological or environmental. Science project topic should always be chosen according to one's standard. There are numerous topic ideas available based on the level and the age of the student.

Some common science fair project ideas suitable for students according to their levels under different categories are listed below:
