K'Nex STEM Design Challenge
Each year, teams are given the “STEM Design Challenge” to find a solution to an engineering problem. Students work in small teams to design and build their project out of a K’Nex Challenge set. Students are then judged on the following criteria: Creativity, Teamwork, Challenge Success, Design, Presentation, Budget.
2022 K'Nex STEM Design Competition
Infrastructure is the framework of our world. Buildings, roads, and power supplies are part of the infrastructure needs of our society. Your challenge is to improve our transportation system. Think of current transportation systems like air travel, vehicle travel, bicycling, etc. In what ways can they be improved to create a safer, healthier, and cleaner world? Or does your team have an idea for a new transportation system? Create a prototype that shows this improved, or new, transportation system. Demonstrate how your system works by moving a ping pong ball through your prototype.
