Design and Technology/Physics KS3 & KS4: Earthquake engineering

Fran Scott meets Dr Bernali Gosh, a seismic engineer, who is planning the new underground network needed in Delhi.

India’s capital city is home for 17 million people, it lies on the Himalayan plate boundary and so is at risk of earthquakes. Delhi sits on wet, sandy soil.

Dr Gosh evaluates experimental models of the effect of earthquakes on buildings on this type of soil.

She is specifically concerned about liquefaction - when sandy ground is shaken it can become a liquid, and buildings therefore sink into it.

Some of the engineering strategies she will use are discussed.

Teacher Notes

This clip could be used in a unit looking at how forces affect different objects in different ways.

Students could carry out a practical where they investigate how different objects float or sink based upon the type of material they are placed upon, for example sand with different amounts of water added to it.

Curriculum Notes

This clip will be relevant for teaching Design & Technology and Physics at KS3 and GCSE in England, Wales and Northern Ireland and 3rd and 4th Level in Scotland. Appears in AQA, OCR, EDEXCEL, CCEA, WJEC, SQA.
