Introduction to 12th Grade Science Fair Projects

12th grade science fair projects can be interesting and even groundbreaking. 12th graders should identify a project idea on their own and can conduct the science fair project and report on it without much assistance. Most 12th grade science fair projects will involve proposing a hypothesis and testing it with an experiment. Advanced models and inventions offer other options for a successful 12th grade project.
