IV. LEARNING TASKS
ELICIT
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.
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.

Grade 8
Quarter 3
ENGAGE
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.
(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.
