LI: To understand the particle composition of solids and liquids

We can explain the differences between solids, liquids and gases by knowing what they are made of.

Scientists have found out that all materials are made of very tiny particles. These particles are so small that we cannot see them with our eyes, or even with a microscope!

The position and behaviour ofthe particles is different insolids, liquids and gases.

SPOTTING STATES OF MATTER

While you arewatching, see which materialsyou can spot,and which states of matterthey are.

Which states of mattercan you identify onthis bottle of lemonade?

Think carefully about the materials that make up the bottle.

GASES

Materials in a gaseous state can spread out tocompletely fill the container or room they are in.

Gases have weight.

Gases can be squashed.

Gases do not keep their shape.

Carbon dioxide is a gas that is all around us. It makes up only about 0.04% of the Earth’s atmosphere, but it can be very useful.

Some fire extinguishers use carbondioxide to cool flame and to stop oxygen getting to the fire.

Carbon dioxide freezes at -78°C, and it becomes a solid called dry ice. It is used to transport food that needs to be keptcool and fresh, such as on aeroplanesand trains.

And as you have heard, carbon dioxide is dissolved in water to create fizzy drinks.

Using the key vocabulary and diagrams below, look for a solid and a liquid in your house and then do the following:

1. Draw a particle diagram for solids, liquids and gases with an example next to it2. Use the key vocabulary box to write a sentence for each, describing their particle

composition.3. Write the properties that each state of matter has next to the particle diagram.

Key Words: Solid, liquid, particles, state, material, properties, arranged, packed.

The particles in a solid are …

The particles within a liquid …

In a gas, the particles are …
