Summary:"Lakes and seas in inland desert areas like the Dead Sea and the Great Salt Lake are famous for being so salty that hardly anything can live in the water. You can tell they are salty because it is very easy to float in them , and very difficult to swim. But just how salty are they? With this activity, students will make """"""""salinity testers"""""""" and measure saltiness of water samples."
