Presentation transcript:

Mirrors and Objects Lv4: Describe how different surfaces reflect light. Lv5: Draw ray diagrams for mirrors. Lv6: Link angles of incidence and angles of reflect to diagram. Entrance Activity Can you crack the hidden code? Use the mirrors provided to work out the secret message your teacher has written for you. Key Words Reflect Ray Diagram Angle of incident Angle of reflection Light box

Teacher Explanation How we see surfaces Even the smoothest of surfaces have small bumps and cracks in them. This is why regardless of the angle that light is hitting an object we can still see the surface. Light bounces off of the object in all different directions. We say that the light has been Scattered.

Reflection Key Word Alert! When light hits the surface of an object and then bounces off the object.

Group discussion You place a burning candle in a completely sealed box filled with mirrors. Every part of the inside of the box is covered with a reflective surface. After 10 seconds the candle goes out because it uses all of the oxygen in the box. After the candle goes out is their still light in the box?

Plenary Assessment Activity Using the alphabet sheet and a mirror write a secret message for your partner to brake. It needs to be a minimum of 5 words long and have a fact about mirrors written on it.
