But water can be a solid, liquid and a gas in the same place. It changes very easy from one state to another within a relatively small change of temperature causing water to freeze or ice to melt.

Light and water do some amazing things together too. If light shines through water it can be spilt into all the colours of the rainbow.

 

But the surface of a pond can also bouce light from its surroundings creating beautiful reflections.

The science of water

Water is not just the most important substance on the planet it is also the most amazing. Take rock for example, at normal temperature its a solid, it needs to be super heated to become to become liquid - such as in a volcano.

           Liquid - Rain                      Solid - Snow                   Solid - Ice                  Gaseos - Cloud

WATER CYCLE

The water cycle is a way in which freshwater moves around the world. Without it, life on earth would be very different.

 

It starts in the ocean, where the heat of the Sun turns sea water into vapour, tiny droplets of water which float in the air - this process is called evaporation. Water vapour rises into the sky to make clouds.

 

The wind blows the clouds over land and they drop their water as rain, sleet or snow. This falls on the land as water, which allows plants to grow and gives us drinking water.

 

 

 

 

Much of the water then flows into lakes and rivers, and is carried back to the sea. Then the process begins again.
