Worksheets and lesson ideas to challenge students aged 11 to 16 to think about light (GCSE and Key Stage 3)
I love teaching light. Students come to your lesson with lots of prior knowledge about light, dark and colours. This video clip can be used alongside questioning to help assess their prior knowledge. What are shadows and how do they form? Would we still have them if light didn’t travel in straight lines? Do all objects create shadows? Is light a wave or a particle?
Refraction and reflection of light
Key Stage 3 and GCSE practical activity on refraction and reflection of light. Students use a series of objects to move light around an obstacle course. If they successfully use refraction and reflection, they move on to total internal reflection. This practical is as an excellent way to revise the light topic. This resource was made in collaboration with Philippa Franks. (PDF)
