III. A. Preparatory Activities:

Teacher’s Activity Student’s Activity
1. ENGAGE

“Good Afternoon Class...”

“Let us pray first...”


“Is there any absentees for today?”


“Thank you _________, for you attendance
report.”



“Good Afternoon Sir.”

Students will remain standing and one student
will lead the prayer.

Class secretary will announce the number of
students present and number of students
absent for the day.

2. A. REVIEW

“Before we proceed with our new topic, who
among you remembers our topic yesterday?”

“Thank you for your participation. Class, our
lesson for today is somehow related to what we
have already discussed yesterday.”

B. MOTIVATION


Teacher will present the picture of a compass.
Can you identify what the object in the picture is
called?

What is the use of a compass?

“Did you know that travelers always use their
compasses to tell whether they are going the
right directions/route?”

Do you know how a compass works? To better
understand how these objects work, let’s watch
this video.

Now, what have you learned in the video?

“Now that we know something about a compass
which is driven by magnets. Our topic will focus
more on what magnetism is. We are going to
have an activity.”

III-B. LESSON PROPER

A. PRE-LABORATORY ACTIVITIES

i. Setting of Standards

“Okay class, what are we going to do if there’s a
group activity?”



One student will answer the topic discussed
yesterday.

















Yes, sir, it is called a compass.



It tells direction.

“Yes, sir, it is much easier to tell which
directions are we going if we use a compass.”


Students will watch the video.



A compass can tell direction through magnets.

Students will listen proactively.

and group mates will clean the materials used
for the activity.

4. 3. EXPLAIN

Through picking the numbers inside the bowl,
we are going to select which group will explain
first their output.



Okay, first group will present their answers.


IV. DISCUSSION

Before we proceed, we have to understand what
magnetism and magnets are. Kindly read their
definitions.





Have you ever wondered where magnets were
discovered?

Please read the first chart.




Very good. Now, lodestones are naturally
occurring magnets. To know more about
lodestones and its history, let us all watch this
short video.

Now that we know the magnets history, we are
going to proceed what its properties are. On our
activity, what have you observed about the
magnets that you used?

What about its parts?

Very good. The first property of a magnet is “It
as polarity – the north pole and the south pole.”

How about the materials they are attracted to?


Materials which can be easily magnetized are
known as ferromagnetic. Kindly read the
examples of ferromagnetic materials, _____.



Leaders A, B, and C, will pick a paper
containing their number. The student who got
no. 1 will come first.



First group will present their answers followed
by the second group then the last group.



Magnetism refers to physical phenomena
arising from the force between magnets,
objects that produce fields that attract or
repel other objects.

Magnets are materials that can attract other
materials due to its intrinsic property.




The first evidence of magnetic phenomena
was observed in the ancient city of Magnesia
where fragments of rocks known as lodestones
were discovered.

Students will watch the clip silently.




It comes in different shapes and sizes.




It has 2 end-poles, the N-pole and the S-pole.




Materials like paper clips and nails are
attracted to magnets while the popsicle sticks
and rubber bands were not.
Examples of ferromagnetic materials include
iron,nickel and cobalt.

5. Now, how about paramagnetic materials? Kindly
read, ________.













And, lastly, paramagnetic. Kindly read, ___.




Therefore, what is the second property of
magnet?

Very good. Now, when you tried to attract two
magnets to each other by placing both N-poles,
what happened?

How about both S-poles?

How about N-pole and S-pole?

The third property of a magnet is?

Very good. Now, what happened to the needle
compass that we have made?

Magnets have two poles – the North-seeking
pole and the South-seeking pole. Moreover, if
we suspend the magnet freely, it will align itself
with the north and south directions. That’s our
fourth property of magnets.

What do you think will happen if we cut the
magnets into halves?

Very good. However, that idea, believed to be a
single pole when a bar magnet is cut into halves,
is what we call magnetic monopole. And it
doesn’t exist.


Paramagnetic materials can also be
magnetized when placed within a strong
magnetic field. However, these materials are
not nearly as magnetically permeable, and
thus will not create nearly as strong a magnet
as a ferromagnetic material will. Also, when
removed from the magnetic field, they will
immediately revert to being non-magnetic. In
other words, they cannot be permanently
magnetized.

Examples of common paramagnetic materials
include aluminum, barium, calcium, uranium
and magnesium.

Diamagnetic materials can not be
magnetized. Examples are water, wood, and
plastic.


Magnets can attract ferromagnetic materials.


It is not attracted.



Not attracted, either.

Easily attracted to each other.

Like poles repel and unlike poles attract.

The needle points toward the North.








The north and south pole separates.

6. Look at this picture.



What have you noticed about the picture?

That is a very good observation. The last
property of magnets is when we cut the magnets
into halves, it will always have a north and south
pole. North and south poles exist independently.

V. GENERALIZATION

How many properties of magnets do we have?

What are those?












Very good.

4. EXTEND

To further understand the lesson, kindly get a
partner. You will review the history and
properties of magnets, then you will write at
least 2 uses of magnets in our daily activities.

5. EVALUATION

Kindly get one fourth sheet of pad paper and
answer the following questions. Write your
name and grade level.

Identification
1. Material that can attract other materials
due to its intrinsic property.


When the magnet is cut into halves, both
magnets have N and S poles.













5

south pole.
2. Magnets can attract ferromagnetic
materials.
3. Like poles repel and unlike poles

4. Magnets have two poles – the North-
