Science fair projects

How it works

Every project here asks one question, changes one thing, measures one thing and tests it three times, which is what a science fair judge is looking for at every grade. Each one comes with every sheet a fair asks for, made from the same project so they all agree: the If… then… because… hypothesis, a results table with the tries across and a mean column from 4th grade, a three-page logbook, the conclusion and a plan of the 36 × 48 inch board.

Nothing here has a flame, a chemical off the kitchen list, an animal, a mold or germ culture, or people as the thing tested. That isn't a promise in a paragraph: the project data is checked in code against those rules, and a project that breaks one can't be shown. Your school's rules still come first, and the rules page says where each one comes from.

Short of time? The easy ones test in an afternoon, from kindergarten up (73 of them), and kindergarten has ten of its own. Keep a project and Peabody counts down to your fair day with a job for each day. Nothing you tap is sent anywhere.
