Turning
This investigation allows children to experiment with turning -
they would not need any prior experience to have a go at these
activities. You might want to encourage children to visualise the
different things described. You could also suggest they actually
find the articles and do what is described to help them. Encourage
the pupils to talk to each other as they try out their ideas. To
make a version of this interactivity which does not require
technology, we just need two differently-coloured discs of thick
paper or card. A slit is cut into each from the edge to the centre
in a straight line. The two slots are then allowed to overlap each
other and turning links the two together.
