Science fair projects are listed on Science Buddies, Education.com and Discovery Education. These sites offer numerous free science projects that users can search to find the best option for a particular field of interest. They also offer guides and helpful tips to make the project go more smoothly.
Science Buddies features a wizard that walks the user through finding the right project, and provides a way for users to browse all projects or search specific keywords to find a project. The site also has a list of projects with kits that users can purchase, rather than buying items individually to recreate a project. Other resources include project guides and a page where users can ask an expert specific questions.
Education.com has a search bar for users to enter keywords and create a search results list. This list can be refined by grade level and subject, to weed out projects that are irrelevant, too easy or too difficult. Each project features a list of required materials and detailed instructions.
Discovery Education has a large selection of projects, and it features a guide to help students decide which project to do. A virtual lab gives users the chance to practice doing the projects before the hands-on work starts. The site also has resources for parents and science fair coordinators.
