Year 6 have been completing a range of practical work this term as part of our Science learning on light. Firstly, we explored how light travels and used torches and mirrors to investigate the angles of incidence and reflection. We have also learnt about the history of periscopes and made models to find out how they work. This week, we have investigated how light travels when it passes through transparent materials such as air, water and glass. We discovered how the law of refraction, which occurs when light rays pass through materials with different density, gave the illusion that images had changed their appearance or disappeared altogether! The "Amazing Arrow" experiment is a simple, mesmerising demonstration of light refraction where a drawn arrow flips direction when viewed through a glass of water.
