A compilation of clips related to electrical circuits, batteries and other power sources. Note: There is no narration in this clip.

As pupils watch the clip, encourage them to say "click" when they see a device that is powered from a socket and "buzz" when they spot something that is battery powered. Pupils may need to view the clip several times before they can agree on exactly where to click and buzz. The children could go on to make collages of images cut from magazines, flyers and catalogues, showing all the electrically powered devices they can find. You could develop the collage as a whole class project, over a period of a week or two, perhaps dividing the display into "mains powered" and "battery powered" devices.
