* Experimental: where it actually involves doing an experiment and coming up with the results of it. Experiments could be hazardous and could need supervision by tutors or seniors who are aware of what to do if something goes wrong.
* Descriptive: deals with something that is already present through demonstration and description.
* Building: or modeling where it could be a model of a vehicle or system.
What The Judges Expect
Science fair ideas and projects must be presented in a systematic way, regardless of its type and topic. For instance, with experimental science fair projects,the document must be presented with the following sections:
An index of contents listing chapters and page numbers, the abstract describing the project and what has been learned from it. The report comes next, demonstrating the background information collected. Obviously the aim of the project must be included along with what it expects to achieve through a "hypothesis" since this is the part of the project that is measurable.
The materials involved in the project must be listed along with how the experiment will be carried out. The results of the project come next, presented as quantifiable data. The entire report is rounded off with a conclusion, which states what was actually learned as a result of the experiment. Finally, the report must also acknowledge people who helped with the experiment by giving them credit and also the sources of reference used.
