In this activity children investigate how mirrors can change the direction of light and use their scientific knowledge to design an invisibility cloak
British scientists have developed an 'invisibility cloak' that allows objects to be masked. So far the device is rather limited - it is 5in (13cm) wide and can hide an object only from microwave beams. In Japan, scientists are working on a material that enables them to project a background image onto a masked object thus making it look transparent.
- how we see objects
Children will learn:
- what happens to light when it meets a reflective surface
- to use scientific concepts to explain how things work
These resources were initially developed in partnership with the Centre for Science Education, Sheffield Hallam University.
