CLEAPSS Supporting practical science and technology
Welcome to the new CLEAPSS Science Website
What is CLEAPSS
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.. (read more)

Food Waste
CLEAPSS has worked closely with DEFRA to establish clear, definitive guidance for food waste disposal in science departments in schools. This follows uncertainty around how the changes in regulation affect handling of what could be consider to be food waste arising from science lessons, especially when the material has been contaminated, intentionally or accidently, by chemicals.

In short, food materials used in science should be double-bagged in opaque plastic and placed in general waste.
