Why is the Dead Sea dead?

The new Earthlearningidea, published today is 'Why is the Dead Sea dead? - measuting salinity'. This involves a simple activity to measure the density of water of different salinities. Pupils can visualise how the measurement of the density of a liquid equates to the commercial measurement of density in situations like that of the Dead Sea and the Great Salt Lake.
This is one of many activities involving resources; all can be found on our website.
