      Lesson details

      Learning outcome

      I can explain that we see things when light is reflected from an object into the eye.

      Key learning points

      1. Reflection involves a source of light and a surface.
      2. Light travels towards a surface and bounces off it.
      3. We often see things because light travels from light sources to objects and then to our eyes.
      4. Scientific diagrams and models can be used to show how we see reflected light.

      Keywords

      • Light source - A light source produces its own light.

      • Reflect - Light is reflected when it hits a surface and bounces off in another direction.

      • Surface - A surface is the top or outside layer of an object or material.

      • Light ray - A light ray is an arrow drawn on a diagram to show the direction in which light is travelling.

      Common misconception

      Light shines out of our eyes; a light ray is a long thin piece of light; light is made of light rays added together; light can only be reflected off shiny surfaces.

      Explicit teaching about sources of light, what a light ray is; plenty of demonstrations and practice of drawing diagrams.

      Teacher tip

      Encourage pupils to think about the journey of light from the source to an object and then into our eyes. See video to demonstrate specific aspects of working scientifically linked to the content of this lesson.

      Equipment

      A ball of wool or string and objects from around the room.

      6 Questions

      Q1.
      How do we see light sources when we look directly at them?

      light from our eyes shines on them
      Correct answer: they produce light which enters our eyes
      light in the air shines on them

      Q2.
      What is the name given to the arrow drawn in a diagram to show the direction in which light is travelling?

      Correct answer: a light ray
      a light beam
      a laser beam

      Q3.
      To light is when light hits a surface and bounces off in another direction.

      Correct Answer: reflect

      Q4.
      How do we see things that are not light sources?

      light shines on them from our eyes
      Correct answer: light is reflected off them into our eyes
      light is reflected off them from our eyes

      Q5.
      Starting with the one which happens first, order these steps explaining how we see things which are not light sources.

      1 - Light travels from a source to an object.
      2 - Light is reflected off the surface of the object.
      3 - Reflected light travels from the object into our eyes.

      Q6.
      Which of these diagrams correctly shows how we see the teddy?

      1
      2
      Correct answer: 3
