This unit introduces the children to the concept of winding mechanisms, building on previous knowledge of wheels and axles. The children explore how to make winding mechanisms using construction kits, then, after discussion, make their own toy using a winding mechanism out of reclaimed materials. The unit uses the context of nursery rhymes and the rhyme chosen can be adapted for a particular class topic.
The unit could be adapted to have a broader focus for the designing and making assignment (design and make a story prop which includes a winding mechanism to make movement) or focus on an alternative context eg machines or cranes.
