EUGENE, Ore. -- Middle school students from across Lane County met at Cal Young Middle School on Saturday for EWEB's 21st Annual Solar Challenge.
The students designed then built solar and battery powered cars as part of their school's STEM learning project.
They competed head-to-head at their schools and the top finishers got to compete at Saturday's Solar Competition.
Organizers said the event aims to teach students about solar energy and the benefits of invention.
"And adding that engineering piece to let them know that inventions really can change the world, or save the world, or that alternative energy is something we can use to power items, and we don't always need to plug something into the wall, in our usual way," said 4J/EWEB Education Partnership Coordinator Tana Shepard.
This year's competition hosted at least 250 students.
They won prizes based on design, hill climbing capabilities, speed, and overall science implementation.
