Join the STEM Design Challenge!!
An exciting engineering competition for students in grades 4–8! In teams of 2 to 4, you’ll put your creativity and problem-solving skills to the test as you tackle a real-world challenge. Using K’Nex, and/or Engino, you’ll design and build a one-of-a-kind project, craft a Design Notebook, and draw up your team’s blueprint.
Bring your best ideas—because the top team at the regional event will earn a spot at the state competition in May! It’s hands-on STEM fun with big-time bragging rights on the line!
The 2026 STEM Design Challenge is Eco-Factory: Build a Sustainable Production Machine!
Design Challenge Explained
In this challenge, elementary and middle school students will design part of a factory that produces a product using sustainable practices and prepare a prototype demonstration to showcase how the machine works and supports sustainable production. Using K'Nex, Engino, and/or recycled materials, the prototype must emphasize sustainability by minimizing waste, maximizing efficiency, and/or using simulated recycled or reusable parts or materials.
