What are some science fair project ideas?

Building a model bridge to demonstrate aerodynamics and exposing metal to chemicals to identify how rust forms are two ideas for science projects. Other ideas are capturing rainwater to create a renewable energy source and creating and analyzing a composting project.

Live Science recommends that students choose projects that relate to areas of study that interests them, such as sports, music or animals. For example, a project that relates to sports involves measuring principles of momentum and force, while a project about principles of sound relates to music, and an interest in animals can lead to project about animal behavior.
