3. When we say “matter” It is anything that
occupies space and has weight/mass. (Repeat
after me)
All the things around us is a matter. Even the
air that we inhale and exhale is also a matter.
What do we call the things around us?
Children, there are three phases of matter.
These are solid, liquid and gas.
The first one is solid. Solids have definite
shapes that occupy definite spaces. Solids can
be held and seen. (Teacher holding the wallet
presented a while ago.) Please come in front
and touch the wallet. Describe what you feel.
What is its shape?
Very good Steven. Now, can you please get a
solid object inside your bag? Come here in
front and show it to your classmates.

Ask a pupil to show his/her water jug to the
class.

glass with the liquid from the jug? (Ask the

the container.
(Teacher holding the bottled water and
balloon) From these two remaining objects,
which do you think is liquid?
Show the last remaining object.) What am I
holding?
What is inside the balloon?
Very good. This inflated balloon is filled with
air and air is an example of a gas.
Can you see the air?
Air cannot be seen because it is colorless. But
it can be felt. Air is a matter in a gas/gaseous
state.
There are also gases that can be seen such
smoke and clouds. (Pictures of smoke and
clouds to be presented.)
(The teacher will ask a pupil to deflate a
balloon and feel the air coming out from it.)
Does the shape of the balloon changed?
So, Gas takes the shape of its container;
therefore, it does not have a definite shape.
Let us have more examples so that you can
really differentiate and identify the states of
matter. You are going to have a group
activity.
