Racing the Sun


Racing the Sun (RTS) is an exciting science, technology, engineering and mathematics (STEM) program that challenges high school students to design, build, and race solar-powered go-karts. It is open to all Arizona high schools. 

Working with teachers and mentors, students spend nine months preparing for Race Day. Along the way, they apply physics, engineering, and energy. They solve real-world problems, using mathematical, analytical, and critical thinking skills. Students are exposed to working in teams and collaborating on ideas. They are challenged to translate their ideas into a working prototype, and along the way, they build leadership skills.
