12th Grade Science Fair Projects

Our 12th Grade Science Fair Projects collection supports teens around ages 17–18 as they undertake capstone-level investigations that can showcase readiness for college or careers. Homeschoolers, afterschooling families, and caregivers will find vetted, secular project ideas in advanced biology, chemistry, physics, environmental science, and engineering that prioritize strong research questions, careful methodology, data analysis, and polished communication. We focus on projects that can be completed safely in home or community spaces while still demonstrating depth. Each idea is reviewed for feasibility, complexity, and alignment with senior-level expectations, with suggestions for adapting to ADHD, autism, anxiety, or 2e profiles. Use the filters to sort by subject, time commitment, and needed equipment or partnerships. If you’re unsure how to choose or structure a twelfth grade science fair or senior project, Modulo’s AI learning concierge can recommend pathways and supports tailored to your teen.
