8th Grade Science Fair Projects

Our 8th Grade Science Fair Projects collection supports teens around ages 13–14 as they take on more independent, data-rich investigations. Homeschoolers, afterschooling families, and caregivers will find vetted, secular project ideas across biology, chemistry, physics, Earth science, and engineering that emphasize hypothesis building, experimental design, data analysis, and clear communication. We prioritize projects that can be completed safely at home or in community spaces without specialized labs. Each idea is reviewed for developmental fit, realistic scope, and alignment with real scientific practice. Use the filters to sort by subject, difficulty, timeframe, and learner needs such as ADHD, autism, anxiety, or 2e, including options that minimize sensory load or social stress. If you’re unsure how ambitious your eighth grader’s science fair project should be—or how much scaffolding to provide—Modulo’s AI learning concierge can suggest project ideas and timelines matched to your teen.
