11th Grade Science Fair Projects

Our 11th Grade Science Fair Projects collection supports teens around ages 16–17 who are ready for deeper, often more specialized investigations. Homeschoolers, afterschooling families, and caregivers will find vetted, secular project ideas across advanced biology, chemistry, physics, environmental science, and engineering that emphasize rigorous design, data analysis, and clear scientific writing. Many projects connect to real-world problems or ongoing research areas. Each idea is reviewed for feasibility, safety, and alignment with high school or pre-college expectations, with options adjustable for ADHD, autism, anxiety, or 2e learners who may need scaffolds for planning and time management. Use the filters to sort by subject, complexity, timeframe, and equipment needs. If you’re unsure how to scope an ambitious but realistic eleventh grade science fair project, Modulo’s AI learning concierge can recommend topics and structures tailored to your teen’s interests and bandwidth.
