Choosing A Science Fair Topic

There are different types of projects that can be entered into a science fair exhibit. Two of the most used and well-known categories include models and investigative projects.


In this category, students are first presented with a problem (as directed by a teacher or conceived through their own observations and imagination) and then create a model or invention that addresses the situation. Examples of projects may include: "What causes a volcano to erupt?", "How do earthquakes form?", or given a standardized set of data including home square footage, a list of appliances, normal gas/electric bills, etc., "How might this homeowner conserve energy?".
Investigative Projects

For this science fair category, students are presented with a problem through which they can form a hypothesis and design an experiment to test it. Examples of projects may include: "Will a nail rust faster in water or fruit juice?", "Will plants growth be affected by music?", or "What do conflicting mental tasks reveal about thinking?"

When choosing a topic for the science fair, be sure to take into account interests, age, skill level, and time needed for preparation. Overall, get ready to learn and have fun!
