Level 3

Students can explore how mirrors reflect light. They can suggest directions in which the light is likely to travel.
Students can explore how shadows change in size and intensity. They can make links between shadows and angles of light from the Sun, a torch, or an overhead projector.
Students can explore various lenses and observe the different ways they refract light.
Students can explore and describe ways in which white light can be split into a spectrum and discuss the idea that white light is made up of many colours of light.

Level 4

Students can investigate how mirrors reflect light. They can explain their observations using ideas about light that scientists have proposed.
Students can describe how the intensity and length of a shadow can change. They can understand relationships and trends in observations.
Students can research how scanners work and attempt to explain how the machine can “read” information in a barcode.
Students can compare their intuitive ideas with scientific concepts about lenses and the refraction of light.
Students can explore and describe ways in which white light can be split into a spectrum. They can make links between their observations and scientific ideas.
