Exploring light energy in the junior classes 

In first and second classes children should recognise that the most important source of light energy for the Earth is the sun. Children should be encouraged to think about their own experiences of light and heat from the sun, for example sunburn, shadows, sundials and growing plants. This work should link with activities in the strand unit ‘Earth in space’ in the geography curriculum.

Pupils should know that light comes from different sources. The children can make a collection of these light sources so that they can be examined at first hand. They should be made aware that they can see objects because the light that shines on the object is reflected into their eyes. It might prove useful for children to imagine themselves in a dark cupboard. When the door is open, light enters and they are able to see. As the door is closed, light is excluded and their vision is reduced.
