Design and Technology KS2: How do sliding doors work?
Presenters Lauren Layfield and Joe Tracini and The Dengineers team help martial arts lover Nya create a traditional Japanese-themed den.
They investigate the engineering challenges of creating the sliding doors, and demonstrate how ball bearings can be used to remove any friction. The balls act as little wheels allowing the doors to slide easily when opening and closing.
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 friction, and work in groups to discover other materials that could be used to reduce the friction between the doors and the frame?
They could list the properties of ball bearings that make them so useful at reducing friction and suggest other ways they could be used.
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.
