Introduction to Solids, Liquids and Gases.

Learning Objectives:

• To know that materials exist as one of the three states of matter.

• To be able to classify materials as either solids, liquids or gases.

• To use previous knowledge to identify materials as solids, liquids and gases.

Put these materials into groups

• Explain why you have put things into these groups.

Three states of matter

solid liquid gas

At room temperature most substances exist in one of three physical states.

The Three States of Matter

Matter can be in one of three “states”. The three states of matter are SOLIDS, LIQUIDS and GASES.

What are their properties?

Solid Liquid Gas

Very difficult to squash, can’t be

poured, can’t change shape

Difficult to squash, can be

poured, can change shape

Easy to squash, can be

poured, can change shape

7G Solids, liquids and gases - In a state!

solid liquid gas

fixed shape

fixed volume

Fill in the table with the answers to these testing questions:

Does it have a fixed shape?Does it have a fixed volume?

7G Solids, liquids and gases - In a state!

solid liquid gas

Is it easy to squash?

Does it conduct heat well?

Can it spread out?

Can it stretch?

Is it heavy for its size?

Now answer some more testing questions about a solid, a liquid and a gas.
