1. CHANGES IN
MATTER
Grade 3
SY 2013-2014
By: Shirley Puaso- Valera

2. KEY
QUESTIONS
 How does matter become
beneficial to our everyday life?
Why it is important to
understand the properties and
the different types of matter?
How can matter change?

3. OBJECTIVES
Analyze how matter changes
physically and chemically.
Demonstrate ways on how
matter undergoes changes in
their properties.

4. Observe the
changes that took
place in the ice
cubes.

5. THINK-PAIR-SHARE
A. Work in pair (or group) and do the following
activities.
- tear a piece of paper
- mold clay into different shapes
- fold a handkerchief into two
B. Observe on the materials while doing
the activity. Ask them the changes that
took place to the materials.

8. PHYSICAL CHANGES IN
MATTER
A. Physical change is a change in how matter
looks, but not the kind of matter is it is.
Tear - Cut
Folded
Mixture - plates broken into pieces
pieces
Solution

9. DIFFERENT EXAMPLES OF PHYSICAL
CHANGE
1. Ice becomes liquid when they are heated. This process
of changing solid to liquid is called melting
 Sublimation – is the process of changing solid matter
to gas without passing the liquid state.

10. DIFFERENT EXAMPLES OF PHYSICAL
CHANGE
2.Mothballs – undergo the process of sublimation once
they are exposed to air.
 Sublimation – is the process of changing solid matter
to gas without passing the liquid state.

11. DIFFERENT EXAMPLES OF PHYSICAL
CHANGE
3.When water is placed inside a freezer, it becomes ice.
This process is called freezing.
Some liquids, like oil and melted butter become hard and
turn to solid when cooled.
Freezing and cooling can change liquid to solid. Freezing
is a change from liquid to solid at a constant
temperature.

12. DIFFERENT EXAMPLES OF PHYSICAL
CHANGE
4. When you boil water, you will observe water vapor or
steam coming out of the container.
Water vapor or steam is the gaseous phase of water.
When we turns into water vapor, the water evaporates.
Evaporation is the process of changing liquid to gas at
a constant temperature or just below its boiling point.

13. DIFFERENT EXAMPLES OF PHYSICAL
CHANGE
5. When you put some cold water in a drinking glass,
droplets of water are formed outside of the glass.
When vapor in the air touches a surface, it turns into
liquid. This process of changing gas to liquid is called
condensation.

24. CHEMICAL CHANGES IN
MATTER
New Matter is formed.
Burning
Rusting
Cooking

CHANGES

26. DECOMPOSITION IS ANOTHER KIND OF
CHEMICAL CHANGE

27. GENERALIZATION
Matter can change from one
form to another.
Physical change is a change in
size, form, or appearance with
no material or substance
formed.
Chemical change is any change
in the properties of matter and
results in the formation of a
new substance.
