Select your science project topic and then click on that to access the introduction page. The introduction page of a project will help you decide if you want to view the project guide.

If a click on project name does not bring up the introduction page, then no project guide is available for the project or the project guide is not complete. 

Recently added project ideas do not have an active link, so you cannot click on them.

Science project ideas in this page may be used for science fair competitions or for class projects.

Can't find your project?

If you have a new project idea that is not listed here, we can assign you a dedicated project advisor to help you on gathering information and designing experiments. 

To use this service you need to upgrade your membership to active membership level. There is a $150 fee for each year that you request such upgrade. (Limited to one project per active member). You need to have at least 3 weeks time for your project advisor to gather information and design experiments.
