Starter Questions
1. Write down 3 ways in which a liquid is different from a solid
2. Is custard a solid or a liquid?
Explain why you think this!

Changes of State
Today we will learn to
Describe the ways in which solids change to liquids and gases.
We will do this by
Revising the water cycle and practicing the words which describe each of the changes
We will have succeeded if

The Water Cycle
In your groups:
1. Put the ice in a beaker on a tripod.
2. Heat the ice and observe what happens
3. While you are doing the experiment, try to draw what is happening to the particles in the ice as you heat it…
Clue: the particles in a solid look like:

The Water Cycle
When solid water (_____) is heated, it becomes a _______. This process is called __________. When liquid water continues to be heated, a _____ forms.
The formation of a gas from a liquid is called __________. When the steam cools down again (_________) it returns to liquid form. A solid can be reformed by ____________.

The Water Cycle
When solid water ( ice ) is heated, it becomes a liquid . This process is called
_ melting___. When liquid water continues to be heated, a gas forms.
The formation of a gas from a liquid is called evaporation . When the steam cools down again ( condensation ) it returns to liquid form. A solid can be reformed by ___ freezing __.

A Confusing Matter!
When cornflour paste is mixed with water, the particles can behave like a liquid or a solid!
Not all particles are the same!
The smallest particles which can exist on their own are ATOMs
When atoms join together they make
MOLECULES.
