9Huia 23 Haratua 2014What we will doWhat we will learnPreliminaries and rollThe importance of starting wellRevisit refraction, starting with the glass block.What refraction is and what causes itInvestigate concave and convex lenses using Scipad page 95What concave lenses do and whyHow to describe the image wellInvestigate convex lenses both close and far from the object (using incandescent gas as the object)What convex lenses do and why. 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
