Over the holiday weekend, Miami-Dade high school students put their STEM skills to the test at the Miami International Auto Show. In a special Electrathon student race, young innovators from four Miami-Dade County schools showcased electric go-karts they built from scratch, according to WSVN. These go-karts, however, were not designed for blistering speed but rather with a focus on efficiency and distance on a single charge.
