U. 5 MATTER and MATERIALS

2. MATTER

3. PROPERTIES OF MATTER
MASS: is the amount of matter that exists in an object. We measure it in grams (g) or kilograms (Kg)
VOLUME: is the space that an object takes up. We measure it in litres (l)

4. TYPES OF MATTER

5. 1) PURE SUBSTANCE HETEROGENEOUS HOMOGENEOUS
Consists only of one We can distinguish the We cannot distinguish
compound compounds the compounds.
2) MIXTURE
Consists of two or more
compounds.

6. SOLID LIQUID GAS
STATES OF MATTER

7. Changes in matter CHEMICAL CHANGE: new matter is formed.
For example: wood is changed into smoke and ash.
PHYSICAL CHANGE: the mass and volume don’t change.

8. CHANGE OF STATE MELTING EVAPORATION SOLIDIFICATION CONDENSATION
SOLID LIQUID GAS
SOLIDIFICATION
CONDENSATION
CHANGE OF STATE

9. Materials We classify materials into two types: NATURAL MATERIALS and
ARTIFICIAL MATERIALS.

10. They come from living things like animals and plants
NATURAL MATERIALS
ANIMAL ORIGIN PLANT ORIGIN MINERAL ORIGIN
Leather, silk, wool Wood, cork, cotton Iron, marble, clay
They come from living things like animals and plants

11. ARTIFICIAL MATERIALS
Wood from trees – Paper Oil from underground - Plastic
They are created by transforming natural materials into different things.

12. PROPERTIES OF MATERIALS
CONDUCTS HEAT
TRANSPARENT
ELASTIC

13. PROPERTIES OF MATERIALS
IMPERMEABLE
STRONG
FLEXIBLE

14. MATERIALS AND THEIR USES
can be
strong and hard and elastic and
impermeable strong smooth

15. Glass is transparent. Bricks and tiles are Electric lines are Cotton, wool and
Windows are made made from clay made of plastic and leather are used
of glass wood to make clothes
and shoes.
HOW MATERIALS ARE USED?

16. Concrete is made from Polyester is used to Asphalt is used to make
cement, sand and rock. make clothes roads.
We use it to made
roads.
HOW MATERIALS ARE USED?

17. MATERIALS AND THE ENVIRONMENT
We can help our environment by following the 3Rs:
Reduce: finish all the pages of your notebook.
Reuse: you can use a showbox to coloured crayons.
Recycle: separate your waste into glass, plastic and paper.

18. QUESTIONS

19. Look at these objects.
Which has a greater mass?
Which has a greater volume?

20. Match the objects to their properties.
Strong, hard, conducts heat
Transparent, water-resistant, does not conduct heat
Strong, flexible, elastic
Plastic cup
Fork
T-shirt

21. Complete the paragraph with the words below.
Litres Volume Scales
Kilograms Matter Mass
…………… has mass and volume. …………. is the amount of matter in one object. ………….. is the space that an object takes up. Mass is measured in …………… and volume is measured in ……………. We use …………… to measure the mass of an object.

22. Look at these pictures.
Which one is a homogeneous mixture and which one is a heterogeneous mixture?
Explain your answer.

23. Classify every natural material in the right column.
ANIMAL ORIGIN
PLANT ORIGIN
MINERAL ORIGIN
Silk Cotton Leather Clay
Wood Cork
Marble

Solid changes to liquid: _ _ _ _ _ _ _
Liquid changes to solid: _ _ _ _ _ _ _ _ _ _ _ _ _ _
Liquid changes to gas: _ _ _ _ _ _ _ _ _ _ _

25. Make a list of the different materials in the picture.
Are they natural or artificial?

26. Which materials are these objects made of?
