Every child. Thinking critically. Solving problems.


Racing the Sun

Racing the Sun (RTS) is a hands-on, innovative engineering program that challenges high school students to design, build, and race solar-powered go-karts. Racing the Sun is a college preparatory program available to any Arizona high school.   

Working with teachers, mentors and industry professional advisors, students spend nine months preparing for Race Day. Along the way, they apply the principles of physics, engineering, and energy. Through collaborative efforts with school sites and educators, race teams solve real-world problems, using mathematical, analytical, and critical thinking skills. Students work in teams and are challenged to translate their ideas into a working prototype and build leadership excellence skills.

Please contact America Miranda, Programs Manager, at with any questions or for more information.
