Materials have different properties depending on whether they are resistant or fragile, rigid or flexible, transparent or opaque, permeable or waterproof, and conduct or insulate heat. Natural materials come from plants, animals, or minerals, and can be transformed into manufactured materials through industrial processes for uses like paper, clothing, furniture, and more.

3. RESISTANT MATERIALS ARE
DIFFICULT TO BREAK

4. FRAGILE MATERIALS
BREAK EASILY

5. A RIGID MATERIAL DOESN’T
BEND EASILY

6. A FLEXIBLE MATERIAL
BENDS REALLY EASILY

7. AN ELASTIC MATERIAL RETURNS
TO ITS ORIGINAL SHAPE

8. LIGHT CAN PASS THROUGH A
TRANSPARENT MATERIAL

9. LIGHT CAN’T PASS THROUGH AN
OPAQUE MATERIAL

10. WATER CAN PASS THROUGH A
PERMEABLE MATERIAL

11. WATER CAN’T PASS THROUGH A
WATERPROOF MATERIAL

12. CURIOUS FACTS:
Our skin is waterproof.

13. Birds like penguins or
gannets need to fish in the
water, so they have
WATERPROOF feathers.

14. A gannet fishing

16. HEAT CAN PASS THROUGH HEAT
CONDUCTORS EASILY

17. HEAT CAN’T PASS THROUGH
HEAT INSULATORS EASILY

19. NATURAL MATERIALS
COME FROM NATURE.
THEY CAN COME FROM
PLANTS.

20. wood

21. cotton

22. Natural
rubber

23. THEY CAN COME FROM
ANIMALS

24. wool

25. leather

26. silk

27. They can
come from
minerals

28. oil

29. MANUFACTURED MATERIALS: They are made
from natural materials that are transformed into
manufactured ones through a manufacturing
process. This process normally takes place in
factories

30. From wood we obtain paper,
books, pencils, furniture, etc.

31. From cotton we get clothes, pillows,
bedding, etc.

32. From natural rubber we take tyres,
clothes, rubbers for school, etc.

33. From wool we obtain clothes, wool string, blankets,
etc.

34. From leather we get clothes,rugs, etc.

35. From silk we get clothes, bedding,
etc.

36. From oil we
obtain
plastic,
nylon for
clothes, fuel,
etc.

37. From sand we get glass
