Is water still water when it's frozen?

Today the children in Room 3 learned a new word - Molecule!
They learned that everything is made up of tiny wee molecules. When they are close together and can't move they make a solid, when they can move a little bit they make a liquid, and when the molecules are really far apart they make a gas.

The children pretended they were tiny wee water molecules.

Here we are a solid (ice)

Here we are as a liquid (water in our drink bottles)

Here we are as a gas (steam from the boiling jug)

We learned lots about solids, liquids and gas yesterday!

We have also used marbles in containers to show water molecules. When we made a solid we packed the marbles in tight and they wouldn't move when the container was shaken. We showed a liquid by putting less marbles in so they could still move a little bit when the container was shaken. We only put 5 marbles in the last container to show a gas.
