Design and Technology KS2: How to create a ventilation system
Presenters Lauren Layfield and Joe Tracini and The Dengineers team help Dilara from Leeds create a Turkish-style den.
They investigate the engineering challenges behind keeping the temperature inside the den just right.
They focus on controlling the sunlight and the ventilation.
They demonstrate how having a door at the back and the front of the den allows air to circulate all the way through and avoids any warm air getting trapped.
To deal with sunlight potentially overheating the den they have no windows in the south side of the den and add a roof window that provides light, but avoids any direct sunlight.
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 how a ventilation system works, and look at how countries in warmer climates use simple techniques to keep a building from overheating.
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.
