On earth day we concentrated climate change, tree planting and many other important Environmental issues. But you know %72 of world surface covered with water. you may start your projects now and finish before world oceans day. here is some sample actvites: Ocean challenge badge A.01 Our Ocean Materials: Internet access or access to reference books. In pairs or on your own, find out some key facts about the ocean (or sea) closest to where you live. For example, how big and deep is it? What human activities go on there? In what other ways does this ocean or sea influence your lives? Put together a quiz for the rest of your group and compare your findings by answering each other’s questions. A.05 Making Fog Materials: A glass jar, a sieve or strainer, water and ice cubes. Carefully fill up the glass jar with hot water. Then carefully pour most of the water out again, only leaving about 3 cm of water in the bottom of the jar. Put the sieve or strainer over the top of the jar and place a few ice cubes (three or four) into it. What happens? The cold air from the ice cubes meets the warm, moist air in the jar, making the water condense and form an eerie fog... OR A.06 Extracting Salt Materials: A shallow dish with sides (e.g. a baking tray), seawater (or a solution of 1½ teaspoons of salt in 250 ml warm water), a protected outside area or a sunny windowsill, scales. Pour 1-2 cm of seawater into the dish and leave it in the Sun. Slowly, the water will evaporate (disappear into the atmosphere), leaving only the salt behind. Everybody guess how long you think it will take for the water to disappear. Once the water has gone, the person who guessed closest can taste the crystals left in the tray, to make sure they are really salt. Collect the salt and weigh it.

What is the biggest sea creature you can think of? What is the smallest? What lives at the coast and what lives out at sea? Have a look at the pictures and reference books and make a list of all the animals and plants that you can think of that live in the sea. Make a drawing, collage or model of what you think life underwater might look like. Put together an ocean display in a public place. to get 100 g of salt? you van find other tasks ın http://www.fao.org/3/a-i3465e.pdf
