CLEAPSS Supporting practical science and technology
Welcome to the new CLEAPSS Science Website
CLEAPSS resources give teachers ideas for exciting and engaging practical activities that fire pupils' imaginations and then, unlike many other sources of ideas, go on to show teachers and technicians in detail how to translate the ideas into safe and exciting experiences in the classroom.
CLEAPSS advice and documentation is recognised by the Health and Safety Executive and the Department for Education.

Chosen UK delegates will get the opportunity to share their passion, skills and projects via a poster presentation alongside teachers from 25 other countries, raising the profile of their work and their school/college at an international level.

“Science on Stage was the most inspirational CPD event I have ever taken part in, as I came away with a myriad of project ideas, strategies and resources to ensure the success of my next project” – Colin Inglis, Boroughbridge High School and 2015 UK delegate. Previous delegate presentations have included challenging gender stereotypes in science, learning themed around human space flight and developing creative science in the outdoor classroom.

We have updated the below CHIP (Old) Hazcards :-

Some of you may have noticed that we have uploaded two new Student Safety Sheets (if not click here). These are about how to handle chemicals. 

We will be updating the Student Safety Sheets, to match the CLP regulations, once we have finalised the CLP Hazcards. We hope to have the new generation Student Safety Sheets out early in 2017.
