How to describe the imageS well.If time, Scipad pages 83, 84, 89, 91 and 94 AND set a date when Mr H can check theseHow to tackle test-type questions on light.See how a coin and a cup prove refractionHow to show refraction occurringIf time, list some applications (in real life) for lenses and mirrors (allude only to sight correctionHow humans use knowledge for their benefitTackle an example of an excellence questionThe sorts of things that excellence questions ask and how to tackle them
