What is the challenge for 2026?? 

Eco-Factory: Build a Sustainable Production Machine

United Nations Sustainable Development Goal 12: Responsible Consumption and Production 

In this challenge, elementary and middle school students, grades 4-8, 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. 

Rules:

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

• Students must create their prototype using no more than 1400 K’Nex and/or Engino pieces. String, tape, and rubber bands are permitted.  3D printed pieces are NOT allowed.

• Teams must bring their materials to the competition and will have 2 hours to recreate their project for judging. 

• There can be no pre-constructed components brought to the competition. Protypes must be built "from scratch."

• 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. 

Awards:

• Awards will be given to top three teams in grades 4-5 and grades 6-8

• The 1st place team in each division (grades 4-5 and grades 6-8) at each Intermediate Unit regional competition will advance to the state competition.

The 2026 State competition will be held on Friday, May 8, 2026 at the Farm Show Complex in Harrisburg, PA.
