CLEAPSS hands-on workshop drop-in

During the ASE 2026 Conference, the CLEAPSS team delivered a busy and engaging two-day hands-on workshop in the Practical Hub. Participants had the opportunity to try a wide range of inspiring Chemistry, Biology and Physics activities.

In Chemistry, attendees made a universal indicator, prepared and fired microscale hydrogen/oxygen rockets and explored new practical procedures comparing the diffusion of halogen gases and vapours. The Chemistry team also presented the concept of an ideal chemical store, which sparked many positive and productive discussions. Visitors were able to share concerns, and the team suggested potential solutions.

The Biology team introduced new guidance on how to culture slime moulds and number of activates you can do with it. The workshop visitors were able to set up a smoke cell to observe Brownian motion and try the prototype for a 3D printed centrifuge, which was used in a practical to separate and observe chloroplasts.

For physics, CLEAPSS staff were demonstrating a lot of the activities and make it guides they've been working on. This includes a DIY air track, a 3D printed motor. We also have been working on some new and exciting practicals, including measuring the speed of light in air, and demonstrating an Arduino powered GM counter unit with a 7-segment display.

Across the workshop, the CLEAPSS team showcased how to make a range of science equipment and shared practical tips for classroom use. Participants discussed and exchanged their own experiences of using these resources in practice.

In addition, conference delegates attended a session led by Magda Polec, Chemistry Adviser, on Thursday 8 January, CLEAPSS: What’s New and Old. The main focus was on the latest CLEAPSS updates, changes to legislation and revisions to chemical hazard classifications. It 

also included reminders of past changes that continue to generate enquiries to the CLEAPSS Helpline. Participants had the opportunity to ask questions and raise concerns.

It was great to see so many teachers and technicians engaging with CLEAPSS throughout the conference.
