Lesson Plan in Science
Lesson 7: Changes that Materials Undergo due to the Presence of
Oxygen and Heat (Grade 5)
I.
LEARNING OBJECTIVE
At the end of the period, the pupils should be able to:
1. Identify the meaning of Combustion;
2. Classify the Presence and Absence of oxygen and;
3. Realize the changes in matter caused by heat.
II. SUBJECT MATTER
A. Topic: Changes that Materials Undergo due to the Presence of Oxygen and Heat
B. Skills: Observing, realizing and Classifying
C. Materials: Visual Aids, Pictures
D. References: Module 4: Lesson 7 and Grade5 book’s .
III. LEARNING ACTIVITIES
Teacher’s Activity
I.
Student’s Activity
Daily Routine
:One student will lead the prayer
a. Prayer
:Let us all stand up and pray
:Good morning ma’am
b. Greetings
: Good morning class!
c. Classroom Management
: Before we start, kindly pick up
any pieces of trash on the floor
and arrange your chairs.
: Student’s will clean up and
arrange the chair
None Ma’am
d. Checking attendance
: Class secretary, is there any
absent today?
: That’s great, Thank you!
II.
Review
: Before we proceed to our topic, can
anyone remember our past lesson?
: Can you give example of Harmful?
III.
: Our past lesson is titled “Changes that
material undergoes: Useful and Harmful.
: Very good class, it seems that you
have mastered our lesson last time.
: Rusting iron, leaching from
decomposing matter and domestic
wastes thrown into bodies of water
releasing odor.
Motivation
: I will group you into two. Group 1
consists of 7members, and Group 2
has 6 members. This game called
“Guess me” You will guess the
picture on the board, and after that
you will write your answer, and the
jumbled letter I will give you, you will
hold it and arrange it according to the
answer you wrote on the board. You
can create a yell so that I know if you
are finish. The group that finishes first
is the winner.
:Yes we are ma’am
: Are you ready class?
(The students will participate)
Group 1 “Burning “
Group 2 “Oxygen”
: What do you think our topic is all
about?
: Changes that matter undergo due to
presence of oxygen and heat.
IV.
Discussion
: From the previous lesson, you have
learned that matter has two
properties, Physical and chemical.
Both of these our properties have
effects on matter. However our
lesson will focus only on chemical
property of matter.
: Let us talk about first the absence of
oxygen, but let’s define first what
combustion is for you to better
understand the absence of oxygen.
: Combustion is a process of burning
something which means for
combustion to occur, three things
must be present.
: A fuel to be burned, a source of
oxygen and a source of heat, and it is
called fire triangle.
: Is it clear class?
: Again, what is combustion?
: Now let’s talk about the Absence of
oxygen or anaerobic. Now suppose
that oxygen will be removed from fire
triangle, what do you think will
happen to fire produced?
:Yes, ma’am
: Combustion is a process of burning
something
: For example, The candle will cover
a jar or glass .
: The candle needs oxygen from the
air to continue burning. If there is
absence of oxygen, the candle will
not continue burn.
(Student will answer)
: are you following class??
:Yes, ma’am
: Now let’s talk about the Presence
of Oxygen or aerobic.
: Have you noticed that when your
mother cuts fruits and vegetables,
some of them change in color?
:Yes ma’am
: For example, When an apple is cut,
the fleshy part of the fruit changes in
color into brown.
: why do you think the color of an
apple changes color into brown?
: because of oxygen
: This is because the oxygen present
in the air reacts with chemical present
in the fleshy part of the apple. And
because of Presence of Oxygen it
will become brown.
: It is clear class?
: Great! Now let’s talk about the
changes in matter through
Application of Heat.
: Do you have any idea what is heat?
:Yes ma’am
: Heat is the quality of being hot and it
is described as how high temperature
is.
: Heat can bring about Physical
changes in Matter.
: For example is a melting ice when
it is placed out of the refrigerator. The
ice absorbs heat from the
surroundings, which melt after a few
: Students will answer
minutes.
: Heat does not only produced
physical change in a material,
sometimes heating a material cause it
to undergo chemical changes.
: The chemical changes caused by
heat are irreversible.
For example, the egg that our
mother cooked for our breakfast has
undergone chemical change by
cooking.
: Fried egg have undergone chemical
change through heat.
V.
Generalization
: Do you understand our lesson
today?
: Again, what is Combustion?
: What will happen when we light up
the candle and cover it with jar or
glass?
: What will happen to the fleshy part
of the apple when we cut it?
: I am glad that all of you learned our
lesson.
VI.
Application
: I will give an activity in which you
will arrange the letter by which the
question is asked.
: Process of burning something
-COMBUSTION
: Quality of being hot
-HEAT
: Impossible to change back to
previous condition
-IRREVERSIBLE
: Thank you for those students who
participated for this activity.
:Yes ma’am
: Process of burning something.
: The candle will not continue burn.
: The fleshy part of apple changes color
into brown.
: Students will participate and answer.
VII.
Evaluation
(The teacher provide a set of
questions which will be answered via
google form)
VIII.
Assignment
In your notebook write your
understanding about the Presence or
Absence of oxygen.
: The students will take the quiz via
google form.
