called?
What isthe use of a compass?
“Did youknowthat travelersalwaysuse their
compassestotell whethertheyare goingthe
rightdirections/route?”
Do youknowhow a compassworks?To better
understandhowthese objectswork,let’swatch
thisvideo.
Now,whathave you learnedinthe video?
“Nowthat we knowsomethingaboutacompass
whichisdrivenbymagnets.Ourtopicwill focus
more on whatmagnetismis.We are goingto
have an activity.”

are goingto selectaleader.”
(pastedonthe board)
Yes,sir,it iscalleda compass.
It tellsdirection.

IV. DISCUSSION
Before we proceed,we have tounderstandwhat
magnetismandmagnetsare.Kindlyreadtheir
definitions.
Have you everwonderedwhere magnetswere
discovered?
Please readthe firstchart.
Verygood. Now,lodestonesare naturally
occurringmagnets.To knowmore about
lodestonesanditshistory,letusall watchthis
short video.
Nowthat we knowthe magnetshistory,we are
goingto proceedwhatitspropertiesare.Onour
activity,whathave youobservedaboutthe
magnetsthat youused?
What aboutits parts?
Verygood.The firstpropertyof a magnet is“It
as polarity – the north pole andthe southpole.”
How aboutthe materialstheyare attractedto?
Materialswhichcan be easilymagnetizedare
knownas ferromagnetic.Kindlyreadthe
examplesof ferromagneticmaterials,_____.
Now,howaboutparamagneticmaterials?Kindly
read,________.
Firstgroup will presenttheiranswersfollowed
by the secondgroupthenthe last group.
Magnetismreferstophysical phenomena
arisingfromthe force betweenmagnets,
objectsthatproduce fieldsthatattract or
repel otherobjects.
Magnetsare materialsthatcan attract other
materialsdue toitsintrinsicproperty.
The firstevidence of magneticphenomena
was observedinthe ancientcityof Magnesia
where fragmentsof rocksknownas lodestones
were discovered.
Studentswill watchthe clipsilently.
It comesindifferentshapesandsizes.
It has 2 end-poles,the N-poleandthe S-pole.
Materialslike paperclipsandnailsare
attractedto magnetswhile the popsiclesticks
and rubberbandswere not.
Examplesof ferromagneticmaterialsinclude
iron,nickel andcobalt.
Paramagneticmaterialscanalsobe
magnetizedwhenplacedwithinastrong
magneticfield.However,these materialsare
not nearlyasmagneticallypermeable,and
thuswill notcreate nearlyas stronga magnet
as a ferromagneticmaterial will. Also,when

5. And,lastly, paramagnetic.Kindlyread,___.
Therefore,whatisthe secondpropertyof
magnet?
Verygood.Now,whenyoutriedtoattract two
magnetsto eachotherby placingbothN-poles,
whathappened?
How aboutbothS-poles?
How aboutN-pole andS-pole?
The third propertyof a magnetis?
Verygood.Now,whathappenedtothe needle
compassthat we have made?
Magnetshave two poles – the North-seeking
pole andthe South-seekingpole.Moreover,if
we suspendthe magnetfreely,itwill alignitself
withthe north andsouthdirections.That’sour
fourthpropertyof magnets.
What do youthinkwill happenif we cutthe
magnetsintohalves?
Verygood.However,thatidea,believedtobe a
single pole whenabarmagnetis cut intohalves,
iswhat we call magneticmonopole.Andit
doesn’texist.
Look at thispicture.
What have younoticedaboutthe picture?
removedfromthe magneticfield,theywill
immediatelyreverttobeingnon-magnetic.In
otherwords, theycannotbe permanently
magnetized.
Examplesof commonparamagneticmaterials
include aluminum, barium, calcium,uranium
and magnesium.
Diamagneticmaterials can not be
magnetized.Examplesare water,wood,and
plastic.
Magnetscan attract ferromagneticmaterials.
It isnot attracted.
Notattracted, either.
Easilyattractedto each other.
Like polesrepel andunlikepolesattract.
The needle pointstowardthe North.
The north and southpole separates.
Whenthe magnetis cut intohalves,both
magnetshave N and S poles.

6. That is a verygoodobservation. The last
propertyof magnetsis whenwe cut the magnets
intohalves,itwill alwayshave anorthand south
pole.Northandsouthpolesexistindependently.
V. GENERALIZATION
How manypropertiesof magnetsdowe have?
What are those?
Verygood.
4. EXTEND
To furtherunderstand the lesson,kindlygeta
partner.You will reviewthe historyand
propertiesof magnets,thenyouwillwrite at
least2 usesof magnetsinour dailyactivities.
5. EVALUATION
Kindlygetone fourthsheetof padpaperand
answerthe followingquestions. Write your
name and grade level.
Identification
1. Material that can attract othermaterials
due to itsintrinsicproperty.
2. Believedtobe a single pole whenabar
magnetiscut into halves.
3. Materialsthat are easilyattractedto
magnets.
4. Materialsthat can be attracted to
magnetsbutnot always.
5. Rocks that can attract iron.
True or false.

1. It as polarity – the north pole andthe
southpole.
2. Magnetscan attract ferromagnetic
materials.
3. Like polesrepel andunlikepoles
attract.
4. Magnetshave two poles – the North-
seekingpole andthe South-seeking
pole.Moreover,if we suspendthe
magnetfreely,itwill alignitself with
the north and southdirections.
5. Northand southpolesexist
independently.
Studentswill dothe activity.
Studentswill answerthe questions.
1. Magnet
2. MagneticMonopole
3. Ferromagnetic
4. Paramagnetic
5. Lodestones
6. False
7. False
8. True
9. True

7. 6. Ferromagneticmaterialsare not
attractedto magnets.
7. Lodestones,whichare the natural rock-
magnets,were discoveredin
Manganese.
8. Like polesrepel,unlikepolesattract.
9. Magnetswhencut intohalveswill have
bothN-polesandS-poles.
10. Magnetscome indifferentshapesand
sizes.
VI. ASSIGNMENT
On yournotebook,please answerthe following
questions.
1. What isa magneticfield?
2. What isa magneticforce?
3. What isthe formulaformagneticforce?
10. True
Studentswill copythe questions. Theyare
goingto researcheitherelectronicorprinted
materials.Answerswillbe writtenintheir
notebooks.
