Examples of both questions and hypothesis derived from those questions are shown in the box. In each case the hypotheses give direction and significance to the initial question. The pH of water in the rivers of our city is more acidic than normal because of acid rain. Experiments should result in a clearly defined data set. Present your work in tables and graphs.

A demonstration project can be interesting but lacks the rigor of experimental design and the testing of ideas. To be successful, the demonstration project should show that the student has learned something new. It should have a clearly defined area of research and information from a variety of research sources. The information should be condensed into a few easily understood relationships. This is an opportunity for a student to develop and improve research skills.
