MATTER
Matter is everything around us that has mass and takes up space. Atoms and molecules
are all composed of matter .
Matter exists in 3 states or forms: Solid, liquid and gas.

Did you know:
Generally, solids are more dense than liquids because their molecules are closer
together. The freezing process compacts the molecules into a smaller space.
SOLIDS
These are the properties, or characteristics, of a solid:
• They have a fixed shape (It’s shape cannot easily be changed)
• It does not take the shape of the container it is in
• It does not fill a container
• Atoms in a solid do not move around too much. They are compact and close together

Materials around us: Solids, liquids and gases
GRADE 4
Paste OR draw 4 pictures, showing examples of solid objects:
Did you know:
Water has more space between its molecules when it is frozen. Because the same
number of molecules take up more space, solid water is less dense than liquid water.
LIQUIDS
Here are the properties of liquids:
• Does not have a fixed shape
• Takes the shape of the container it is in
• Difficult to compress because the molecules are close together
• Liquids “flow”
• Atoms are spread out a little more than solids
Activity 2:
Paste OR draw 4 pictures showing examples of liquids:

GASES
These are the properties of gases.
• Gases are everywhere
• Do not have any particular shape
• Take the shape of the container they are in
• The molecules spread out to fill the whole space evenly
• Molecules are spread out more freely
Activity 3:
Paste OR draw 4 pictures showing examples of gases:

Quick questions
1)
What is matter? ________________________________________________________ _____________________________________________________________________
2) Give a synonym (another word) for the term “properties”. ______________________
_____________________________________________________________________
Practical activity
Your teacher will provide a variety of objects, such as these: stone, wood, can of
deodorant, air in a balloon, milk, water, oil, plastic cup, cooking gas in a cylinder.
Look at each of the items and use these questions to decide if the object is a SOLID, a
LIQUID or a GAS.
• Has it got a fixed shape or, can its shape change easily?
• Does it take the shape of the container it is in?
• Does it fill the container?
