In this unit, children apply knowledge about electric circuits that they have acquired in science in a purposeful way. They learn to design and make something that will shine light eg a table lamp, a light in a room, or one that lights up a poster, a Christmas tree or a display. The children will also need to consider what kind of lights are switched on and off by remote control eg in a corridor or in a home so that it looks lived in. While many of the designing and making skills will be used, there will be two particular focuses. The children should be encouraged to define a set of clear specifications for the light by considering who will use it, and the conditions under which it might be used. They may also use ICT tools to support their research into a range of lights and to control their light, switching it on and off when required.
Unit 4D 'Alarms' is an appropriate alternative to this unit. The alarms can be controlled through the use of a simple switch, a control box or computer program.
