Physics – Let's get it working!

CLEAPSS provides advice for teachers, technicians, science advisers and H&S officers on all aspects of physics practical work - We know that physics experiments can be tricky to set up and get working. If you’re stuck get in touch by e-mail or 'phone and we can help! We also have suggestions for low cost 'make it yourself' equipment – recent examples include, a Planck’s constant LED array and a mobile phone spectrometer/microscope.

CLEAPSS also works with science equipment suppliers to ensure that their products are safe and suited to the physics classroom.
