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.
