The Colchester Zoological Society’s STEM Design Challenge is a FREE project offering children from the chance to solve real-world problems faced by zookeepers and staff at CZS and beyond! Following the STEM design process and using science, technology, engineering and maths skills, children will reimagine a new design for an animal enclosure.

How to Participate:

  • 1) Register as part of the project once registration opens
  • 2) Teachers (and other leaders) can participate in an optional virtual training and information session about STEM design thinking – early Jan 2026
  • 3) Students develop their enclosure design prototype and work to refine and redesign it
  • 4) Classes can (optionally) participate in a virtual feedback session on their design progress (Feb 2026)
  • 5) Students finalise their design in summer term, and submit them for entry into the Contest!

Looking for inspiration?

From January-July 2024 children used their creativity, ingenuity, and STEM thinking to help us imagine our ‘Future Zoo’ and how our Mixed African Paddock could be redesigned for the future. Over 10,000 children participated in the initial Challenge.
