1st Grade Science Fair Projects

Our 1st Grade Science Fair Projects collection supports children around ages 6–7 as they try simple, structured explorations. Homeschoolers, afterschooling families, and caregivers will find vetted, secular project ideas that focus on asking questions, making guesses, observing changes, and sharing findings with drawings or simple charts. Topics include plants, weather, materials, and basic physical science using safe, household supplies. Each project is reviewed for clear directions, realistic scope, and developmental fit, with options for kids with ADHD, autism, anxiety, or 2e profiles. Use the filters to sort by subject area, time needed, and adult involvement. If you’re unsure how much structure a first grader’s science fair project needs—or how to keep it fun instead of stressful—Modulo’s AI learning concierge can recommend a few age-appropriate ideas and supports.
