This document discusses a group activity where students observe and record the special properties of various materials, including chalk, a sponge, a rubber band, a nail near a magnet, and an electric wire. The special properties observed include porosity, ductility, brittleness, elasticity, malleability, flexibility, luster, magnetism, and electrical conductivity. The document explains that special properties pertain to the unique characteristics of specific materials and phases of matter. It lists several examples of special properties and has students identify special properties from descriptions.

2. What are the general
properties of
materials?
Mass
Volume
Density

3. What special talent do
you have?

4. Products are composed of materials
and materials are composed of matter.
Materials differ from each other – they differ
in their properties, the products they make,
their uses, and the ways on how we can
dispose of them.
The properties of materials can be
classified into two:
• General properties
• Special properties
Let us study the second property of
matter – the Special properties of materials.

8. Group Reporting
• How did you find the
activity?
• What did you learn from
the activity?
• What are the special
properties of materials in
your activity?

9. • What are the
properties of materials
that you have observed or
learn?

special properties of
materials?

10. The previous activity
that you had pertains to
the special properties of
matter. Special properties
pertain to the unique
properties of one phase or
kind of matter.

11. 1. Porosity – The ability
of a material to hold liquid
to a certain extent.

12. 2. Ductility – It allows a
solid material to be
transformed into wires.

13. 3. Brittleness – A property
of solids to be broken into
pieces.

14. 4. Elasticity - A property
of solids to return to their
original shape after being
stretched

15. 5. Malleability - A property
of solids to be hammered
into sheets.

16. 6. Flexibility – The ability
of a material to be bent
without breaking.

17. 7. Luster – The ability of
a material to reflect light.

18. 8. Magnetic – the ability
to attract materials made
of steel and iron.

19. 9. Electrical – The ability
to conduct electricity.

20. Can you now describe the
special properties of
materials?
What is/are the use/s of
special properties of
materials to us people?

21. Why are the special
properties of
materials important?
