LEARNING EXPERIENCE

Teacher’s set activities Topic: Magnetism

Date: October 15, 2015

Daily routine a) Greetings Good morning class! b) Prayer Okay, let us start our class today with a simple prayer, may I ask everyone to please stand.

Students’ Response Assessment Good morning sir!

The students stand,

Let us put ourselves in the presence of God, Students praying. in the name of the father...

Psychomotor Perform the task sheet about how magnetism works.

Values Integrated: To understand the importance of magnetism in our daily life and to gain more knowledge about its concept.

c) Setting of the class Before you take your seat can you please pick up the pieces of thrash on the floor and arrange your chair. Are you comfortable with your seats?

Student picking up the trash and arranging the chair. Yes Sir!

5 minutes True or False. Write T if the statement is true and F if the statement is false. 1. The ends of a magnet are where the magnetic effect is the strongest. These ends of a magnet are what we call the “core”. 2. A magnet is a material or object that produces a magnetic field. 3. Opposite pole always

Okay that's good. Affective: Distinguish the relationship of electricity and magnetism in our real-world experience and especially in our field of work.

Mr. ________, are there any absent today?

None sir!

Okay that’s good

II. 4 minutes

Lesson proper a) Activity: Let’s watch a short video clip. Please watch carefully because I’m going to ask you questions at the end of the video clip. b) Analysis: The student will answer the following questions: 1. How was the video clip? 2. Based on the video that we watched. Do you have any ideas about our lesson for today?

45 minutes

c) Abstraction: So our lesson for today is all about Magnetism. What comes in your mind when we say magnetism?

All of your answers are correct. Magnetism and basic electricity are so

Okay sir (Students watching)

Sir it was funny. Sir I think it’s about magnet.

Students raise their hand and answer the question.

repel. 4. Alternating current can reverse the poles of an electromagnet. 5. The peculiar behavior of electricity under certain conditions is caused by magnetic influences. 6. Permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. 7. A magnet has two types, the permanent magnet and the electromagnet. 8. A magnet is not surrounded by a magnetic field. 9. Magnet is the main source of magnetism. 10. Neodymium magnet is an example of a permanent magnet.

closely related that one cannot be studied at length without involving the other. Assignment Research about AC voltage and how it works. Write in a whole sheet of paper.

So there are 3 general relationship that exist between them: 1. Current flow will always produce some form of magnetism. 2. Magnetism is by far the most commonly used means for producing or using electricity. 3. The peculiar behavior of electricity under certain conditions is caused by magnetic influences. The importance of the magnetism plays a key role in circuit protection and control devices. The importance differs based from the module. Let’s talk about the main source of magnetism. Can you guess what is it?

Sir, it is a magnet.

That’s right! So what it a magnet? Can you please read the meaning of a magnet Mr. _________.

Every magnet has three common properties.

It is the material or object that produces a magnetic field.

1. They attract and hold iron. 2. They all have two poles, one north and one south. 3. They will assume close to a north-south alignment, if permitted to move. The ends of a magnet are where the magnetic effect is the strongest. These ends of a magnet are what we call the “poles”. Like the earth a magnet has also 2 poles. These are the NORTH and the SOUTH pole. Always remember that like pole always repel and opposite poles always attract. A magnet is surrounded by a magnetic field. This magnetic field is consists of flux lines or the lines of force that extend into space from one end of the magnet to the other. There are three types of magnet. Can you guess what those are? Give one. Okay that’s right. So the types of magnet are Permanent magnet, Temporary magnet, and Electromagnet.

Student raising their hands.

So what is a permanent magnet? Can you please read Mr.__________. Okay thank you. So a permanent magnet is like a battery of IPhone. This magnet is built with its own magnetic field.

Permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field.

So these are the example of permanent magnet: 1. Neodymium magnet 2. Samarium Cobalt magnet 3. Alnico magnet 4. Ferrite magnet Next type is the Temporary magnet. This magnet act like permanent magnets when they are within a strong magnetic field. For example if you leave a hairclip or a nail sticking with a magnet for a long period of time and then remove it then a small amount of magnetic field will still retain in that object for a short period of time.

And lastly is the Electromagnet. Can you please read Mr.____________.

Magnetic field is produced by an electric current. The

So for example I have here an iron nail and I magnetic field will coil the wire in to the nail for at least 20 disappears when the turns then I will remove the insulation from current is turned off. the wire and connect the both ends to the side of the battery. Watch what will happen. So as you can see if a current flows through the wire, this will create a magnetic field that is also transferred in the iron nail or what we call the “core”. Take note. Changing the direction of the current flow can reverse the poles of an electromagnet. But alternating current changes direction on its own. The relationship between current flow and flux lines can be demonstrated using the right and left hand rule. There are two ways you can use to easily understand the hand rule. It is the Right-hand grip rule and the Fleming’s left hand rule.

d) Application: Now to sum up our lesson, I would like you to bring out the materials that I asked for

Students bringing out the materials and stay

our activity today and then go to your respective group.

to their group.

The materials we will be needing today are the following: a. 1.5 V battery (D size) b. Magnet c. 2 safety pins d. Rubber band e. Magnetic wire I have here a task sheet and what you are going to do is to follow the instruction and perform it then answer the questions after the task. Steps: 1) Connect the safety pins at the both side (positive and negative side) of the battery. 2) Secure the safety pin with a rubber band. Make sure to tighten so it will not move. 3) Coil the wire and leave some allowance at both ends of the wire. 4) Remove the insulation of the wire by sanding it with a sand paper. 5) Put the both ends of the wire to the head of the 2 safety pins. 6) Lastly, stick the magnet to the battery near to the coiled wire.

Students listening to the instructions.

Students performing the task sheet.

The student will answer the following question written in the task sheet: 1. Was it hard to do the task? Why? 2. What have you observed in the coiled wire after you have finished the task 3. What makes the coiled wire act that behavior? 4. What concept can you give for the conclusion of your task
