PBS Teachers

In this 'Energy Education for the 21st Century' design challenge, students construct and evaluate a solar-powered model car. Students utilize the design process and undergo review by their peers to select an optimal gear ratio and components for their car. As a culminating activity, students compete in a Solar Sprint race modeled after the National Renewable Energy Laboratory's Junior Solar Sprint competition.

Activity takes four to ten 50-minute class periods depending on depth of investigation. Additional materials necessary.

Energy Literacy

Humans transfer and transform energy from the environment into forms useful for human endeavors.
Other materials addressing:
4.1 Humans transfer and transform energy.

Benchmarks for Science Literacy
Learn more about the Benchmarks

Energy from the sun (and the wind and water energy derived from it) is available indefinitely. Because the transfer of energy from these resources is weak and variable, systems are needed to collect and concentrate the energy.

Teaching Tips

  • A great project for a science club or group of students on independent study.
  • After the activity is completed, the instructor should have students reflect on how their car design relates to solar energy and spend time considering other uses for solar energy and implications regarding climate.
  • This activity provides another option for energy consumption and independence solutions.

About the Science

  • Students design and build a solar-powered vehicle, utilizing all STEM (Science, Technology, Math, and Engineering) domains.
  • This is a collaborative, creative solar engineering project that requires long-term effort and commitment.
  • This activity does not explicitly teach how a solar cell works but rather investigates factors to optimize the electrical power generated by one.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • This activity is extremely well-thought-out and organized. Students have an opportunity to compete against each other (or even other schools) and test their solar cars.
  • The activity is engaging and integrates STEM disciples to spark students' creativity in designing a solar car.
  • The activity encourages teamwork and builds skills in working as a group to solve a problem.
  • Students will need to know some basic mechanics – acceleration, force, mechanical advantage, etc. – to be successful with this activity.

Technical Details/Ease of Use

  • This activity requires a solar kit that costs about $32 per group of students, which amounts to spending about $8 to $10 per student.
  • Some students will need careful guidance with materials, especially those who are not used to building.
