Materials are made from matter, including the ones that we cannot see, such as air.

The balloon takes up space and can be weighed (3.0g).

The balloon has been blown up. Even though we cannot see air, we can see it is taking up space in the balloon and it can also be weighed (3.1g).

Matter is anything that takes up space and can be weighed.

  • Materials like plastic, wood and glass are made from matter.
  • Everything that takes up space and can be weighed is made from matter.

States of matter

  • Matter can exist in three different states: solid, liquid and gas.
  • The state of a material depends on its temperature.
  • Some materials, like water, can exist in all three states depending on the temperature.

Question three

Can it change shape?

Question one

Question two

Can it be compressed?

What happens when it is poured?

What is a solid?

This deflated balloon does not take up much 3D space; it has a small volume.

This inflated balloon takes up more 3D space; it has a larger volume.

This balloon is being squashed to make the volume smaller; it has been compressed.

Can it be compressed?

  • Volume is how much 3D space something takes up.
  • Something that can be squashed to take up less space has been compressed.
  • Squashing can cause something to change shape and have a smaller volume as it has been compressed.

The shape of the balloon has changed but the volume is the same; it has not been compressed.

What happens when it is poured?

  • When things are poured, some will flow and others will not.
  • When some things are poured, they will take the shape of the container and others will make a pile.

The water flows from the jug to the glass and takes the shape of the glass.

The sand flows from the truck and lands in a pile.

Can it change shape?

©2022 Kapow Primary

www.kapowprimary.com

  • Some things, when left, will stay the same shape.
  • Some things will take the shape of the container they are in.
  • Some things will escape their container if it has no lid!
  • Some things will change shape if a force is applied to them.

Conclusion two: a solid has a fixed shape and volume.

Conclusion three: a solid does not have a fixed shape or volume.

Conclusion one: a solid has a fixed volume but not a fixed shape.

Correct.

Incorrect. A solid cannot be compressed and the shape will only change if a force is applied.

Incorrect. A solid has a fixed shape; force must be applied to change the shape of a solid.
