~Did you know that our bodies are made up of 65% water.

~Our world's surface is two-thirds covered in water. Look at a map to see the seas and oceans the cover our planet. Other bodies of water are lakes, rivers, streams, ponds and canals.

~Water takes on three different forms:
1.) Solid - frost , snow, ice.
2.) Liquid - rain, lakes, oceans, streams, ponds and rivers.
3.) Gas - water vapour.

~Temperature changes water's three forms:

1.) Heat - in very hot climates the sun causes water to evaporate and change into vapour.

2.) Cool - when the weather cools down, it causes the vapour to turn into rain.

3.) Cold - in very cold conditions, the water freezes and changes into a solid.
