Salty Seas
Salt water is denser than freshwater. That is why we float so much more easily in the sea than in a lake or a swimming pool. An object will float if it is less dense than the water surrounding it. Therefore, things float easier in salt water as it is denser than freshwater. This is particularly evident in the Dead Sea where the salt content is higher.
In this resource students will explore density and the effect that adding salt to water has on floating and sinking eggs. It demonstrates why things float more easily in our oceans.
