11 liquid (water)...

12 and gas (steam)

13 A molecule of water consists of two atoms of hydrogen and one atom of oxygen.

16 Look at our Earth. It is beautiful blue, because about three quarters of it is water…

17 But 97% of it is salt water, 2% - ice in the north, more than 0,95% is somewhere in the ground or it is too dirty. We can drink only about 0,05% of the Earths water.

18 Fresh water is not there for everybody and our world is changing fast. Every year there are about 80 million more people on our Earth and they all need clean and fresh water.

19 We need to drink at least two litres of water every day and we can only last a few days without water…

20 …because about 70% of the human body is water.

21 We have to think very carefully about water, and about our use of it. We cant afford to waste it!

24 CHILDREN CAN CONSERVE WATER!

25 If you notice that water is running freely, please, turn off the tap.

26 Save water when you are washing or washing the dishes, do not turn on the tap to the full.

27 Turn off the tap while you are brushing your teeth. Just pour water into the glass and turn off the tap.

28 Find a leaky tap around the house? Tell a parent so it can get fixed!

29 Use the fridge if you need to cool a bottle of water or lemonade
