Light and Shadow

What will I know at the end of the Light and Shadow unit?
(QCA EXPECTATIONS)


children will (must should could):

1. explain that shadows are formed when light from a source is blocked;
2. explain that even transparent objects block some light and form shadows
3. recognise that shadows are similar in shape to the objects forming them;
4. describe how a shadow from the Sun changes over the course of a day;
5. changes in shadows from the Sun over the course of a day arise from the movement of the Earth
6. make predictions about the shadows formed by different objects or materials and
7. make careful observations and measurements of the shadows
   

Projects which could address all of these objectives:

• Research and compare materials which you should use to make a pair of sunglass lenses.  Make a short talk or presentation which summarises what you have found out.
• Make a shadow puppet play which uses some coloured shadows to show mood or setting
• Make a class sundial for children to use to tell the time when they are in the playground.  Prepare a brief email which can be sent to Heads of Year which explains what you have done and how to use the sundial to tell the time.
