The Siemens Foundation established the Siemens Competition in Math, Science & Technology in 1999. The Competition is the nation’s premiere science research competition for high school students and seeks to promote excellence by encouraging students to undertake individual or team research projects. It fosters intensive research that improves students' understanding of the value of scientific study and informs their consideration of future careers in these disciplines.
You can compete as an individual or as a member of a two or three-person team. Scholarships for winning projects range from $1,000 to $100,000.
