Description These rainbow glasses are part of a range of science toys, kits & teaching aids for teaching about light & colour for schools and in the home. Use for engaging science at home or in the classroom! Teaching ideas for Rainbow Glasses These glasses split white light into rainbows; perfect for discussing the visible spectrum, refraction or perhaps light emissions from stars. Light diffraction through fireworks glasses Discuss the visible light spectrum (red through to violet). Compare energy levels of visible light with UV light and the rest of the spectrum. Get students to wear the rainbow glasses and rock back and forth whilst looking at a white light source (not the Sun!). They will see the rainbow spectrum stretch and compress slightly. When light sources move away from you their light is RED shifted, whereas if they move toward you the light is BLUE shifted. It is this Doppler effect that Edwin Hubble used as evidence for the Big Bang Theory as he observed galaxies moving further and accelerating faster away from us and everything else. Split light using a glass prism Focus red, green and blue lights on a whiteboard. During the demonstration: Turn each light on individually. These are primary light colours Mix pairs of lights to form secondary coloursRed Green = Yellow Red Blue = Magenta Blue Green = Cyan School science visit that expands on this science teaching resource Find out about the Light & Colour School Science Incursion Find out about the Light & Colour School Science Incursion
