In this STEM building challenge, my students engineered sorting devices to separate a mixture of marbles, beads, coins, and dice-but with a twist. Their entire device had to fit inside a cereal box when closed. Working within Pennsylvania’s new STEELS Science Standards, which emphasize technology, engineering, and evaluating solutions to technical challenges, students designed and built custom filters to tackle the task. Many teams took innovation to the next level, using technology to 3D print precision filters for optimal sorting. This hands-on challenge pushed them to think critically about design constraints, efficiency, and real-world engineering applications.
