Description

An explanation of longshore drift and how it is affecting one farm in Holderness on the east coast of England. A group of children conduct an experiment to see how longshore drift works. Longshore drift is where particles of clay are transported down the coast. The particles are finally deposited further down the coast and new land is formed. The coastline is therefore always changing. The seaside town of Withernsea in Yorkshire uses coastal protection in the form of a large sea wall and groynes. This is known as a hard point.

Classroom Ideas

This clip introduces a wealth of key vocabulary related to coastal erosion and how coastlines change as a result of longshore drift. As a result, an activity could involve pupils matching key words - such as boulder, sediment, groyne - to its definition. Pupils could then be challenged to label pictures of coastlines with the vocabulary they have learned. Pupils may like to create mini models of the features documented in this clip using modelling sand and showing how material transportation can be reduced by sea walls and groynes. A whole class discussion may allow the pupils to understand the importance of sea defence methods, to protect farmland which has been developed on coastlines. Pupils could go on to design and think about innovative ways to protect the continually changing coastline.
