A science fair project involves investigating a question using the scientific method. Students conduct experiments to answer their question and gather data. They then prepare a final report and display board to showcase their work. The final report includes an abstract, background research, methods, results, and conclusion sections. It comprehensively documents the project from question to findings. The display board visually summarizes this for judges and viewers at the fair. Strong projects have a clear question and testable hypothesis to generate meaningful results.
