In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects. Learners will test their covers using a model "drainage pipe system" with a waterproof container, a cover frame, and water-safe "litter" objects. Includes step-by-step instructions with pictures, extensions, and adaptations for younger engineers. A Spanish version of the activity is also available.
