CLEAPSS Chemistry
Chemistry – Let's make it happen!

CLEAPSS provides guidance for teachers, technicians, science advisers and H&S officers on all aspects of practical work. We know that chemistry experiments can cause problems and activities may not 'work' as expected, or provide the effective learning opportunity that’s required. Sometimes, health and safety concerns are raised about the chemicals involved.

CLEAPSS works with suppliers and others to ensure that suitable chemicals and equipment are used in schools and we can also suggest ideas and innovative methods that might help you enhance practical chemistry in your school.
