Design and Technology KS2: How to create a working drawbridge
Presenters Lauren Layfield and Joe Tracini and The Dengineers team help brothers Alec and William from Inverness create a castle-themed den.
They investigate one the main features of the den, a working drawbridge. To open and close the drawbridge they use a chain and barrel mechanism and demonstrate how the barrel winds the chain up and down to move the drawbridge.
This could be used to introduce the process of design, and as a prompt for class discussion and learning in areas such as initial research, designing and making a structure.
They could investigate the barrel and chain mechanism and how it could be used to operate different devices.
This clip will be relevant for teaching Design and Technology at KS2 in England, Wales, and Northern Ireland and 1st and 2nd level in Scotland.
