A look at the River Tweed and its course through the Southern Uplands of Scotland. The Tweed has its source in the Lowther Hills and starts as a tiny stream. As it flows downhill it gets bigger and bigger, with more water entering from other streams and rivers such as the Teviot. These are called tributaries. Finally it reaches Berwick-upon-Tweed where it enters the North Sea.
After watching the clip, children could show their understanding of how rivers can start small and grow larger and larger until they reach the sea, by producing a piece of drama or movement using more and more people (which signifies more and more water). The children could also show the different contours that the source of the river will encounter and label them and show them on small whiteboards as the piece is being performed. Blue fabric could also be used to enhance the production of the piece.
