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 will come to your lesson with lots of prior knowledge about light, dark and colours. This video clip below can be used alongside questioning to help assess students’ prior knowledge – the world is a scary place without a scientific understanding! What are shadows and how do they form? Would we still have shadows if light didn’t travel in straight lines? Do all objects create shadows? Is light a wave or a particle?
Luminous and non-luminous objects, transparent,translucent and opaque
Key Stage 3 worksheet on luminous and non-luminous objects. Students classify objects as luminous and non-luminous, and opaque, translucent and transparent. Students then draw ray diagrams to show how we see luminous and non-luminous objects and finally show light interacts with different materials. (PDF)
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)
Properties of light
Key Stage 3 synoptic worksheet on the main properties of light. Students use a photograph as a stimulus to work with their partner to identify the main properties of light and then example them. This activity would be best done at the end of the light topic to help consolidate understanding and support students to make links between lessons. (PDF)
