Grade 5 Lesson: Take Out the Trash: Cleaning Our Rivers

As our population grows exponentially, raw materials become more and more limited—so engineers must be imaginative in how they repurpose materials already available to them. The engineers in Haiti, as seen in Dream Big, worked under the constraint of using only immediately available materials. In this engineering challenge, students will create a device that cleans plastic pollution from a river system by using only reclaimed plastic from that very system.
