More than 70 per cent of the Earth's surface is covered by water, forming a huge global sea. If you tasted the sea water, you would find that it was very salty, unlike the fresh water in rivers and lakes. The sea has many fascinating rhythms as its tides flow in and out, and it is teeming with life, from tiny single-celled creatures to gigantic whales. You can start discovering the wonders of the sea whenever you visit the coast - and by reading this exciting information and project book! Mix your own seawater and test its saltiness with a homemade hydrometer. You can create a replica of a submarine periscope, and use an ordinary glass to simulate how a diving bell works. Photographs and diagrams clearly explain the experiments and illustrate the scientific principles behind them, so young readers will want to dive straight in and find out all about the sea for themselves.
