Why is the Dead Sea dead?

Why is the Dead Sea dead? This is a classroom activity to measure the density of water of different salinities.


The Dead Sea in the rift valley between Jordan and Israel is the lowest point on land on the Earth’s surface. Most of the water that flows into the Dead Sea does not flow out again but is evaporated in the highly arid conditions. At the end of this ELI, pupils can:-
- describe how dissolving salt in water increases the density of the water;
- describe how a ‘floater’ can be used to measure the density of solutions.
Many more good ideas for teaching can be found on our website.
