Science fair guru Maxine Levaren gives walks you step-by-step through every phase of choosing, designing, assembling and presenting a blue ribbon science fair project. She gives you the inside scoop on what the judges are really looking for and coaches you on all the dos and don'ts of science fairs. And she arms you with in-depth coverage of more than 50 winning projects, including: Projects involving experiments in virtually every scientific disciplines Computer projects that develop programs to solve a particularproblem or analyze system performance Engineering projects that design and build new devices or test existing devices to compare and analyze performance Research projects involving data collection and mathematical analysis of results

The experiment for the popcorn science fair project can be initiated by lighting the Bunsen burner at a very low rate, letting the flame impinge lightly upon the base of the beaker. Illuminating the light source will show a steady stream of steam coming out of the beaker. Eventually, the popcorns will start popping and the stream of steam will become more prominent.

The procedure follows the hypothesis, which explains how you attempted to answer your science fair project question. This part of the process deals with the experiment(s) you may conduct. After you have completed your experiment(s), you will display your results, showing what happened during the project. During your experiment, you should take notes in a spiral notebook on everyday changes that will help you explain and present the results.

Some science fairs allow experiments with live animals and others don't. For example, one classic experiment (found in most older science fair project books) involves changing the temperature of fish tank water and seeing what it does to the respiration rate (breathing) of goldfish. In some places around the country, that experiment would not be allowed at all. In others, you would need a special permission form guaranteeing that you will take good care of the animal. In other places, they don't yet have such restrictions. Again, use common sense.

Hypothesis: A science fair experiment ALWAYS compares two variables. That means that you are comparing one action to another action to see what works and what doesn't work. You must include all six steps of the scientific method for kids.
