- %CO:A,12,72%Attaiment target 15: Using light and electromagnetic radiation
-
- Pupils should develop their knowledge and understanding of the
- properties and behaviour of light and electromagnetic waves.
-
- Level 1 * know that light comes from different sources.
-
- * be able to discriminate between colours and match them, or
- where appropriate, demonstrate an understanding of colour in
- the environment.
-
- Level 2 * know that light passes through some materials and not
- others, and that when it does not shadows can be formed.
-
- * be able to draw pictures showing features such as light
- colour and shade.
-
- Level 3 * know that light can be made to change direction and that
- shiny surfaces produce images.
-
- * be able to give an account of an investigation with mirrors.
-
- Level 4 * know that we see objects because light is scattered off them
- and into our eyes.
-
- * know that light travels in straight lines and use this to
- explain the shapes and sizes of shadows.
-
- Level 5 * understand how light is reflected.
-
- Level 6 * understand how prisms and lenses refract and disperse light.
-
- * be able to give an account of the structure and function of
- the eye.
-
- * understand the principles of common defects of sight and
- their correction.
-
- Level 7 * be able to describe and use the wave model of the nature of
- electromagnetic radiation.
-
- * know that there are many types of electromagnetic radiation,
- that they are important in everyday life, and be able to
- describe some of their applications.
-
- * be able to explain how some optical devices work, for
- example, simple camera, projector and optical fibre.
-
- * understand refraction as an effect of differences of
- velocities in different media.
-
- Level 9 * know that the electromagnetic spectrum forms a continuum of
- radiation with differing physiological effects.
-
- * be able to select, summarise and present information
- concerning the application of electromagnetic waves in
- domestic contexts, communication and medicine.
- Level 10 * understand the processes of dispersion, interference,
- diffraction, and polarisation of light.
