​

​Volume is how much space something uses

• cubic centimeters cm³ or

  ​cubic meters m³

​States of Matter

​Matter can be found all over the universe in different states.

​

​Solid e.g Rock

​

​Liquid e.g. Water

​

​Gas e.g Gas

Multiple Choice

• House

• Milk

• The moon

Multiple Choice

Which is NOT a Liquid?

• Blood

• Milk

• Water

• Hair

Multiple Choice

Which is NOT a gas?

• Air

• Snow

• Carbon dioxide

• Oxygen

​So why are there different states of matter?

​Particles

​All matter is made of tiny things called particles.

​

​They are too small to see.

​

​e.g Water is made of water particles

​

​

​Particles

​

​Particles are always moving.

​

​Particles are attracted to other particles.

​

​How close these particles are to each other, decides what state of matter it is.

​

Multiple Choice

What do we call the tiny things that all matter is made from?

• Particulars

• Tiny Things

• Particles

• Icicles

Multiple Choice

Can we see particles?

• Yes

• No

Multiple Choice

Particles are attracted to each other, and the are always ________

• Growing

• Moving

• Getting smaller

• Very quiet

​In a solid the particles are very strongly attracted to each other.

​

​They are still moving but they are always touching.

​

​The particles in a liquid are able to 'flow and slide' over other particles.

​

​They are still attracted to each other but they are more free to move.

​

​A gas does not have a fixed volume.

​

​It will expand and fill whatever space it is in.

​

​You can also compress or 'squeeze' a gas to make it smaller.
