ENGAGE
Show two pictures to the
class (one matter and one
non matter). (Example:
nonmatter: picture of light
from a torch, heat from the
fire, sound from the police
siren (forms of energy);
Matter: picture of any solid,
liquid or gaseous
substance. Let the
students cite the
differences between the
two and write them on the
board.
Ask the students what
could be the possible
characteristics/ properties
these pictures have.
Explain that these objects
do have properties and that
is the objective of the
lesson.
Show to the students a
glass of water. Obtain
ideas or concepts they
have in mind regarding it.
Let the students get a piece
of paper. Ask them to tear
the paper into small pieces
until they won’t be able to
tear it anymore. Find
someone who had torn the
smallest piece and present
it to the class.
Tell the students to look
around and let one student
mention one object to the
class.
(Prepare two identical cups
and water)
Show to the class one
small drinking glass full of
water and one empty. Get
a volunteer and ask him to
weigh the two.
Ask the students on what
they observed with the two
objects.
(Students must infer that
water has mass)
Get their opinion from the
question: Is it possible to
divide still the paper into
the very smallest of it?
Then, explain the concept
of indivisibility of matter’s
composition.
Using the object presented,
ask the student what are
the materials that object is
made up of.
State:
“Everything you see or
imagine is built from
something else.” This
concept will be further
discussed for today’s topic.

9. It is the measure of
the amount of matter the
object has. (mass)
10. It refers to the
space occupied by an
object. (volume)
Let the students check the
other properties of the
following matter (hardness,
texture, color, malleability,
electrical conductivity)
1. silk cloth
2. plastic straw
3. copper wire
Identify the following
1. He believed that atoms are indivisible.
2. It is Greek word which means indivisible
particle.
3. It is the smallest particle of an element.
4. It consists of two or more atoms.
5. It is the unit of length used to measure
size of an atom.

Tell the students to get an aluminum
foil and cut it into small pieces.
In case it could not be cut anymore with
their bare hands, use a microscope or
magnifying glass to look at the tiniest
piece.
If you have better tools, you could still
cut the aluminum into
tinier pieces.
