Prayer
Ok class, let's all stand up for a prayer to be led by (name of student)
In the name of the father …Amen…
Greetings
Good morning class…
Good morning sir
Putting class to order
Before you take your sit please pick up the pieces of paper and arrange you chairs properly…
Ok now you may take your sit
( the students will follow the given instruction)
Checking of attendance
Ok Miss Secretary who is absent for today?
(the secretary will check the attendance)
Teachers activities
Students activities
Checking of assignments
Class last meeting I gave you an assignment? Right?
Ok let's check it
Ok class who got a score of 5, 4…1 or 0? Please raise your hand
Ok please pass it to the center then forward
Yes sir!
(the students will check the given assignments)
The students will raise their hands once I say the scores
The students will pass their assignments
Review/Recap
Last meeting we discuss all about (last topic discussed)
Now who can tell their insights about it?
The students will raise their answer
motivation
I've prepared symbols and words under your chair… then you will paste it and present it on the board.
Word(s) and symbol(s):
(+),(-) attracts,(-),(-), attracts, (+),(-), and repel
Answer :
"opposite sign (charges) attract and same sign (charges) repel".
Ok let's start…
Ok thank you class…
That principle is connected to our topic, you will further understand as we go along within…
Ok sir …
The students will perform the given activity
Lesson Proper
Lesson proper activity:
The students will be given an activity which is related to the topic and will be divided into two groups. Using the following materials: horse shoe magnet, bar magnet, iron fillings and coupon bond
Teacher's activities
Students activities
Ok class, we will have an activity which is closely related to our lesson topic for today.
Ok, you will be divided into two groups.
(the instruction will be given by the teacher written above)
Now tell something about what you have observed.
Count 1 to 2. We will start from the back. Ready …. Count …
Ok group one… please cite your observation about our activity.
Ok, now let's hear what group 2 has to say about out activity
Very well said guys…
Let us give ourselves a round of applause…
(The students will count to form two groups)
1, 2, 1, 2……
group one will site their observation.
Group two will site their observation
Lesson Proper II
Teachers Activity
Students activity
All your answers and observations are correct…
The lines that you observe created by the iron fillings and magnet under, is often so called the MAGNETIC FIELD lines which falls under the magnetic fields
But first what is a magnetic field? Anyone? Yes ? (call a student)
Magnetic fields are produced by electric currents, which can be macroscopic in wires and microscopic associated with electrons in atomic orbits.
A magnetic field were first in such way that iron fillings will point in the direction of the field
And now what is a magnetic field line?
A region of space near the magnet, electric current, or moving charge particle in which a magnetic force acts on any other magnet, electric current, or moving charge particles..
This field usually centered along two poles which are usually allocated as north and south
Understand?
And now let me ask you how magnetic field lines and arrows are being drawn, in terms of using two poles which are usually allocated as north and south
Anyone? Yes.. (call a name of student)
(the teacher will teach the lines and arrows drawn, in terms of using two poles, which are usually allocated as north and south. And of course with the use of principles given in the motivation)
"OPPOSITE SIGN (charges) attract and SAME SIGN (charges) repel "
So can anyone distinguish the arrows itself.?
Did you understand class?
(Students will read it)
Yes sir…
(The student will cite his or her answer)
YES SIR.!!!
Generalization
Teacher's activities
Students activities
(The students will raise questions based on what they have understood/ learned in the class discussions.)
Anyone from the class who can generalize our class discussion with your own words or explanation?
Yes… (call a name of student)
That's great it seems you learned a lot from me. Let us give ourselves a round of applause.
And get one whole sheet of paper
Magnetic fields were force in such way that iron filings will point in the direction of the field
This field is usually centered along two poles
"OPPOSITE SIGN (charges) attract and SAME SIGN (charges) repel "
