2026 Challenge

Eco-Factory: Build a Sustainable Production Machine:

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 and/or Engino, as well as supplementary recycled materials (optional), the prototype must emphasize sustainability by minimizing waste, maximizing efficiency, and/or using simulated recycled or reusable parts or materials.

April 10, 2026

Competition Rules:

• A team of 2-4 students will work together on the project.

• Prototype Materials: K’Nex and/or Engino (up to 1400 pieces.) 

• String, tape, and rubber bands are permitted.  3D printed pieces are NOT allowed. 

• Supplementary Materials: (Optional) Recycled or reused materials may be incorporated into other aspects of the model outside of the K'Nex/Engino prototype. See challenge.

• Teams are responsible for bringing their materials to the competition. There can be no pre-constructed components. Teams will have 2 hours to recreate their project for judging.

• Projects must fit on a 6-foot-long table.  Water may not be used as part of the display. 

• Each team will need to create and submit a design notebook and a blueprint for viewing at the competition.

• Each team will need to prepare a presentation (2 minutes or less) on their model and how it answers the challenge.

If you are having difficulty purchasing/finding K'Nex, you can also purchase Engino sets.  The recommended sets can be found here:
