Unit 4F: Simple circuits: L.O. 1, 2: N.C. 4.1a
Unit 6F: How we see things Unit 4F: Simple circuits: L.O. 1, 2: N.C. 4.1a

Unit 6F: How we see things

Unit 6F: How we see things
Unit 6F: Vocabulary Some useful words Opaque Reflect Reflection Light beam Mirror Light travelling A material that light cannot pass through When light ‘bounces’ off a surface in particular shiny surfaces such as mirrors An image viewed in a mirror, for example A thin column of light such as projected by a torch A shiny surface that reflects light Light is always moving Unit 6F: How we see things

Unit 6F: How does light travel?
Unit 6F: How does light travel?: L.O. 1, 2: N.C. 4.3a

Unit 6F: How does light travel?
Unit 6F: How does light travel?: L.O. 1, 2: N.C. 4.3a

Unit 6F: How do we see things?
Unit 6F: How do we see things?: L.O. 3: N.C. 4.3d

Unit 6F: Reflection: L.O. 4, 5: N.C. 4.3c

Unit 6F: Reflection: L.O. 4, 5: N.C. 4.3c

Unit 6F: More reflections
When light is reflected it’s direction of travel changes angle i = angle r Unit 6F: More reflections: L.O. 6, 7: N.C. 4.3c

Unit 6F: Shiny and dull surfaces
You are going to investigate what types of surfaces reflect light the best, shiny or dull. Test each of the surfaces to record whether it reflects a light beam from a torch and whether you can see yourself in the surface or not. Can you draw any conclusions from your results? Surface Dull or shiny Light reflected from torch I can see my face reflected Mirror Polished metal sheet Sheet of perspex Sheet of paper Piece of polished wood Shiny painted surface Dull painted surface Unit 6F: Shiny and dull surfaces: L.O. 8, 9: N.C. 4.3c

How can we change the size and position of the shadow? Plan how you are going to investigate this? What will you change Unit 6F: Shadow investigation: L.O. 10, 11, 12, 13: N.C. 4.3b
