States of Matter

Targets...Today we will be:

• Developing our knowledge and understanding of solids, liquids and gases– I can give examples of solids, liquids and gases– I can describe the differences between solid, liquids and

gases

• Developing our knowledge and understanding of particle arrangements– I can describe how particles are arranged in solids,

liquids and gases

What are things made of?

Spot the similaritySpot the difference

Similarity:They are all made of the same particles. Hydrogen and oxygen (H₂O) = WATER.

Difference:The water particles are in different states.

Solid (ice)Liquid (water)Gas (steam)

Words to describe...Solids Liquids Gases

How do you know whether something is a solid, liquid or gas?

How would you explain to an alien:

What a solid is?

What a liquid is?

What a gas is?

Shape

Do solids, liquids and gases have a fixed shape?

Volume

Do solids, liquids and gases have a fixed volume?

Volume: Can you squeeze it?

Flow

Do solids, liquids and gases have a flow?

Solid, Liquid or Gas?Sort the substances into solids, liquids and gases.

You should be able to explain why...

Solid, Liquid or Gas?

Mix some cornflour with water.
