 * Activities**
 * 1) Read through pages 152 and 153 of exploring science 8, answer questions 1-4
 * 2) Watch the demonstration of reflection at a plane mirror (this simulation from [|freezeray.com] is helpful)
 * 3) Investigate the relationship between the angle of incidence and reflection
 * 4) Watch the animation to find out why reflections appear to be further away than the mirror that reflects them. This is why mirrors make rooms appear to be bigger.
 * 1) Now investigate and find out if this is true by completing [|Ray diagrams for mirrors]
 * 2) [|Investigate curved mirrors] and answer the questions
 * 3) Extension: Read about [|Georges star] and complete the questions
 * 4) Lighting candles from a distance demonstration

Review completed classwork / key term quiz
 * Summary**

Make your own persciscope at home, if you can't find small mirrors then use aluminium foil instead (try to keep it as smooth as possible). Draw a diagram of your periscope, label it and write a short paragraph to explain how it works.
 * Homework**

Trouble remembering the law of reflection? See if you can find it [|here]
