Ideas for a science fair project can be found on websites such as Science Buddies, NASA and Science Fair Extravaganza. The science fair ideas are grouped by topic and level of difficulty.
Science Buddies website lists science fair project ideas in the areas of physical science, life science, engineering, earth and environmental science, behavioral and social science and math and computer science. On the website, there are options to browse all projects, to search for a project and to find projects for which kits are available.
Science Fair Extravaganza website offers science fair project ideas in three categories: easy projects, medium projects and challenging projects. Among easy projects there are ideas such as testing a bag's strength or capacity of a battery. Medium projects include testing C-Strength of a balloon by puncturing it ten times without the balloon popping. One of the challenging projects is the recreation of Galileo's gravity experiment.
NASA website provides science fair ideas on the topics of space, earth, solar system and sun. It also mentions possible goals of a science fair project, such as testing an idea, answering a question or demonstrating how nature works. Furthermore, the NASA website contains a step-by-step guidance to preparing a science fair project from picking a topic to practicing the presentation.
The science fair project ideas presented by Energy Quest focus on different sources of energy. Electricity projects include creating an electromagnet, simulating lightning bolts and creating light through friction. Other ideas include creating a steam powered rocket-boat, researching the heat from light bulbs and demonstrating how the force from air can move a vehicle.
Ideas incorporating ideas in chemistry, engineering, force, movement, sound and water are available from the PBSKids website Zoom. Suggested ideas include examining the behavior of yeast, safely dropping an egg from a height, understanding optical illusions, using balloons to create movement and creating a miniature biodome.
Utah State University offers ideas appropriate for students of different grades. For younger students, the extension suggests experiments demonstrating the pH level of water, while older students may look at the runoff of fertilizer or methods of monitoring the toxicity of water.
Experiments such as examining the liquid used in glow-sticks and looking at surface tension by resting a paper clip on water are suggested by Scholastic.
