This was a very early blog comment post on another blog. It has been transferred to this blog.

I thought I had better blog the comment on "SPLASH (Water related theme)" as this would allow me to add some photos I've taken as well...

What is water? It's a compound made of two parts hydrogen and one part oxygen. It can be made when hydrogen and oxygen are together and are sparked. The two gases explode in their reaction and water is produced. This can happen when lightning passes through the atmosphere or can be done in a lab (but is very dangerous).

Water is important to life.

We drink it

Our problem is, most water in the world isn't suitable for drinking. It can be polluted or too salty yet most of the world's surface is covered in water.

This is why The Water Cycle is so important to us. When studying water, The Water Cycle shows us how water can move through the environment. Water EVAPORATES into water vapour and rises up into the air. As it cools, it forms into droplets. The droplets combine and when large enough fall as rain, now free of salt or pollutants.

You could try a simple experiment to see how The Water Cycle works...

You will need
two saucepans
a hot plate
water
ice

Method
An adult should always help when dealing with hot plates.
1. Put water in one saucepan and place it on hot plate to boil.
2. Put ice in the second saucepan.
3. Hold the saucepan with the ice above the saucepan on the hot plate when the hot plate pan has boiled.
4. Watch underneath the saucepan with ice and report what happens.

Such a simple compound, yet so important. If it's no longer there...

Possible things to study....

The Water Cycle
How can we filter dirty water?
Keeping it clean. (looking at ways to reduce pollution)
Pond life. (looking at plant and animal life in ponds or streams)
States of Matter. (looking at water in its forms as solid, liquid and gas and the effects of temperature. Did you know water boils at a different temperature the higher you are?)
Surface Tension. (looking at the effects of detergent on water surfaces.)
