This list supports learning about mechanical systems including levers, linkages, pulleys and cams with 7–11 year-olds. Providing ideas for developing skills used in D&T through focussed practical tasks. There are lots of opportunities for children to work on exploring mechanical systems looking at how they work and are how they are put together. Children then design, make and evaluate their own designs and made any modifications they feel are needed to make them suitable for the purpose and audience that they have been designed for. Ideas for D&T projects include a range of relevant contexts including home, school, industry and the wider environment.
