Top 10 free science fair project sites

Peabody is on this list and we say so. Every other row is what that site's own page showed when we opened it on 30 October 2026. Science Buddies would not let our reader in, so it isn't described here.

How it's ordered: Project sites first, by how many projects a family can browse for free; then the rule and judging pages a school's own rules are built on.

The ten, in order

  1. Education.com science projects: About 1,700 project write-ups with a K–8 grade filter and subject filters. Some cards had no grade label, and a paid plan sits behind the site.
  2. Peabody science fair (ours) (ours): Ours. Fewer projects, but the picker hands over one in four taps, and each comes with the hypothesis frame, a results table, a logbook and a board plan to print, checked against school safety rules in code.
  3. All Science Fair Projects, by grade: Sixty-two projects on its 4th grade list alone, with Easy and Medium labels, and lists for other grades. The lists show no materials, steps or safety notes.
  4. Steve Spangler's experiments archive: Over a hundred experiment pages, dozens tagged for science fairs, mostly with everyday materials. Some use fire or need gear a school would refuse; check each one.
  5. KiwiCo's science fair project lists: Short lists by grade with a line of science each. No materials or steps on the list, and kit adverts between the projects.
  6. Society for Science, ISEF rules: The international rules most regional and state fairs follow, with its Rules Wizard. Written for high school; the source of the review rules for people, animals and microbes.
  7. UNM STEM-H Center K–5 rules: The most complete elementary rule set we found: what may be displayed, what needs review, and the forms. A PDF for New Mexico's fairs, useful anywhere.
  8. Alpine School District judging procedures: What judges actually ask and how long they spend: two judges, four to five minutes a project.
  9. Scientific American: five questions from a judge: The five most common judge questions and what a good answer does. Written with high school fairs in mind.
  10. Washington County (Utah) district rules: A real district's rules in one PDF, including the board size limit and favouring children's own words. Dated 2011.
