This short lesson starter for Year 1 science pupils gives a clear example of how light is needed to see, with a man taking his dog for a walk in the woods.
Dick puts his dog Woody on his lead, but lets Woody off his lead when they're in the woods. Soon it's quite dark and Dick can't see Woody anywhere.
Remembering he has a torch in his pocket, Dick shines it all around the woods. All of a sudden there's a glint in the darkness - is it Woody's dog tag reflecting the light from the torch? Find out in this Key Stage 1 science video.
