We had to have a Health and Safety talk before we did our experiment. We could not do this experiment ourselves. An adult had to demonstrate it because it involved boiling water and we could get scalded if the water went onto our skin. So, for this experiment we had to watch and listen carefully and stay a safe distance from the equipment.

Our goal was to explore water in its gas state so, we watched what happened when cold water was heated up in a kettle. The bubbles stared off tiny and moving slowly then they got bigger and bigger as the water got hotter.

The bubbles were full of air or gas.

When the water was at 100oC it was at boiling point. Then steam started to come out of the spout. This was water in its gas state. The bubbles in the boiling water were now huge.

When a mirror was held over the spout the steam hit the cold surface, it became condensated and we witnessed the steam turning back into liquid water again.

We got really excited when we looked out of our classroom window and saw what was happening on the Nursery  roof.The water was evaporating, steam was rising into the air and this was us seeing water as a gas in real life. We couldn’t have planned it better!
