7th Grade Science Fair Projects

Our 7th Grade Science Fair Projects collection supports tweens around ages 12–13 as they design more sophisticated investigations. Homeschoolers, afterschooling families, and caregivers will find vetted, secular project ideas that help students ask testable questions, control variables, analyze data, and present findings clearly. Topics span life science, physical science, Earth science, and engineering, with options for different budgets and timeframes. Each idea is reviewed for safety, developmental appropriateness, and potential to teach real scientific thinking instead of just “wow” demonstrations. Use the filters to sort by subject area, estimated time commitment, required materials, and learner needs such as ADHD, autism, anxiety, or 2e, including lower-stress and low-mess options. If you’re not sure how complex a project your seventh grader can realistically manage—or how much parent support is appropriate—Modulo’s AI learning concierge can recommend project ideas and planning steps tailored to your family.
