The Broken Umbrella Challenge
Pupils explore materials, invent with waste and become circular economy pros!

Overview
In this hands-on workshop, pupils take apart broken objects, explore materials and use the parts to invent something new. They explore waste and circular design, thinking like scientists and engineers to become climate problem solvers.
Pupils first learn about how everyday items can be reused or recycled to reduce waste. They then put this into practice by designing, building and testing their own inventions using broken toys and household items sourced from charities.
The workshop is open-ended, giving pupils freedom to develop their own ideas. STEM Ambassadors are on hand to help if they get stuck. They are all studying or working in STEM, giving pupils the chance to meet relatable role models and learn how STEM skills solve real-world problems.
School sessions can be adapted for team working. The workshop is also accessible for pupils with special educational needs and disabilities (SEND), with more structured sessions available for SEND groups.
