Design and Technology KS2: How to create a structure with a rotating roof

Presenters Lauren Layfield and Joe Tracini and The Dengineers team help budding astrophysicist Helena from Dumfries and Galloway create an observatory style den.

The structure will have a roof that can rotate 360 degrees to give a full view of the night sky.

They demonstrate how this can be achieved by sitting a domed roof on fixed castors that will allow the roof to rotate smoothly but keep it securely in position.

Teachers Notes

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.

Pupils could come up with their own roof designs that would allow you to view the night sky. What are the advantages and disadvantages of having a rotating roof?

Curriculum Notes

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.
