Hey, everyone, it's Ms. Panchal here, and I'm so glad that you've joined me on today's science lesson.

Now during the lesson today, we're going to be thinking and exploring putting magnets together, and we're going to be looking at two key words, attract and repel.

So we've got lots of fantastic learning to do today, so let's get started.

So the outcome for today's lesson is: I can predict whether two magnets will attract or repel each other depending on which poles are facing.

So we're going to go through a few keywords now and we need to practise saying them.

So I'm going to say the word and I would like you to say it back to me.

My turn, poles.

Your turn.

Super.

My turn, attract.

Your turn.

Excellent.

Well done.

My turn, repel.

Your turn.

Fantastic job.

My turn, opposite.

Your turn.

Super work.

And lastly, my turn, prediction.

Your turn.

Fantastic work, everyone.

You've done such a great job of practising saying these words.

Now don't worry too much if you're not sure what these words mean as we're going to be talking about them throughout the lesson and we're going to be learning about what they mean.

So we have poles, attract, repel, opposite, and prediction.

Now some of you may have heard of these words before or used them before, and some of you may be not so sure, but that's okay because we're going to learn about them during today's lesson.

So our lesson today is going to be split up into two sections.

The first part of our lesson, we're going to be answering this question, what happens when you put two magnets together? So we're going to be exploring that idea.

And then the second part of today's lesson, we're going to be thinking about those two key words that I mentioned earlier, attract and repel.

So let's get started with the first part of the lesson.

So all magnets have two poles and we've got a picture of a bar magnet here.

We can see an S and an N.

Now do you know what the poles are called? So think back to the learning we've done on magnets so far and have a think about, do you know what the poles are called? You might want to pause the video here, either mention it to your talk partner or you might want to jot down your ideas.

The poles are called north-seeking and south-seeking, and sometimes they're labelled N and S.

So super job if you remembered what the N and S stand for, and what the poles are called.

The north-seeking and south-seeking poles are opposite poles.

Now, magnets attract magnetic materials.

So we can see in this diagram here, we've got a bar magnet and the paperclips are attracted to the magnet.

Now, sometimes you can see the magnetic material pulled towards the magnet by the magnetic force.

Now, magnets do not attract non-magnetic materials.

And previously we've looked at examples of non-magnetic materials.

So my question to you now is, what happens to non-magnetic materials when they are near a magnet? So again, pause the video here for a moment.

Either talk with your talk partner as to what the answer to this question might be, or you might want to jot down your ideas.

I'll give you a few moments to have a think.

Well done if you said nothing, because nothing will happen.

So magnets do not make non-magnetic materials move.

So if we have a look at this picture here on the right hand side, we've got a non-magnetic cork not attracted to a magnet.

So we can see that the bar magnet is being held and the cork is staying on the table surface.

The cork is not attracted to the magnet.

So we're now going to do a question just to check on the learning that we've done so far in today's lesson.

So the question is, which is the opposite pole to the north-seeking pole on a magnet? Is it A, west? B, east? C, north? Or D, south? So I'm going to give you a few moments to have a think and then we'll go through the answer.

Amazing work, everybody.

The answer is D, south.

So the next question is, we're going to match the two halves of each statement.

So the first start of statement says magnetic materials and does it end with are not attracted to magnets or does it end with are attracted to magnets? And the second sentence starter we have, non-magnetic materials are not attracted to magnets or are attracted to magnets.

So I'll give you a few moments to have a think about how these sentences can be joined up and then we'll go through the answers very soon.

Amazing work, everybody.

Well done.

So let's recap on this question.

Magnetic materials are attracted to magnets, and non-magnetic materials are not attracted to magnets.

Well done, everyone.

So let's move on now.

A magnet is made from magnetic materials.

Now what would happen if you put a magnet near another magnet? Do you think it will make a difference if you put a north and north poles together or south and south poles together or north and south poles together? So I want you to pause the video here for a moment and I want you to have a think about those questions there and those options.

Do you think it will make a difference? Either have a quick chat with your talk partner or jot down some of your ideas, and then click play once you're ready to continue the lesson.

So we're now going to move onto the first task.

So we're going to be investigating putting magnets together.

So the first step is to stick two post-it notes together and punch a hole through the ends.

Now you may need to ask an adult to help you with the hole punching.

Once you've done that, I'd like you to thread a rubber band through the hole to make a pouch just like in the picture on the screen.

The third step, I would then like you to hang a bar magnet in the pouch and bring a second magnet close to the hanging magnet.

And now for this investigation, what I would like you to do is observe what happens with different poles facing each other.

So use the bar magnet that's hanging with another bar magnet and I want you to observe, so look with your eyes what happens with different poles facing each other.

So pause the video here and follow these instructions to then observe what happens with different poles facing each other.

And then we'll talk through some of the observations a little bit later on.

Off you go.

Super work, everyone.

I hope that you made some fantastic observations.

So you may have seen, when the two north-seeking poles were close together, the magnets pushed and span away from each other.

You may have seen when the north-seeking pole of one magnet was close to the south-seeking pole of the other one, they pulled together.

And when the two south-seeking poles were close together, the magnets pushed and span away from each other.

Or you may have seen something a little bit different.

Well done, everyone, for your work so far.

We're now going to move on to the second part of today's lesson and we're going to be thinking about these two key words that I mentioned earlier.

We've got attract and repel.

So a north-seeking pole will attract a south-seeking pole.

And we've got this diagram here that helps us to understand that.

So we've got two bar magnets here.

We've got a south-seeking pole and the north-seeking pole, and they will be attracted to each other.

A south-seeking pole will attract a north-seeking pole.

So again, we've got another diagram here, two bar magnets.

We've got a north-seeking pole and a south-seeking pole.

They will be attracted to each other.

Now, the opposite poles of magnets pull on each other.

Now, the reason in these two diagrams we can see that the magnets will be attracted to each other is because they're opposite poles.

However, two north-seeking poles or two south-seeking poles will push each other away.

We say that the same poles of magnets repel each other.

So let's have a look at this diagram to help us understand.

So we've got two bar magnets here and we've got both the north-seeking poles facing each other.

And this would mean that the magnets repel each other.

And again, we've got another example where the both south-seeking poles are facing each other, but they will repel against each other.

Magnetic force is a non-contact force, so magnets do not need to be touching each other to attract or repel.

They just need to be near each other.

So if we have a look at our diagrams again, we've got the first diagram, which has got the south-seeking on one side, the north-seeking on the other, and they'll be attracted to each other.

And on the second diagram, we've got the north-seeking and north-seeking pole, and they will repel each other.

So scientists make predictions to say what they think will happen in an investigation.

And you may have made predictions in your other science lessons.

Now, predictions often help you plan what you'll do or look for in an investigation.

So often when you're planning an investigation, making predictions is really useful and really helpful to you.

Now Sofia here says, "I predict that the magnet will attract the paperclip but not the rubber." So that's the prediction that Sofia has made.

We can make predictions about whether we think two magnets will attract or repel each other.

So let's do a quick check of our learning so far to make sure that everybody feels confident with the learning that we've done.

So we've got a sentence here and we've got a word missing.

So I'm going to read the sentence to you and then we'll have a think about what the missing word is.

If you put two north-seeking poles close together, the magnets will push away or each other.

So have a think about the learning we've just done and have a think about what that missing word is.

I'll give you a few moments and then we will talk through the answer.

Amazing work, everybody, if you said repel.

Now our next question here is we're going to match the two halves of each statement.

So let me read them to you.

So the first start of statement is, opposite poles on a bar magnet, do they attract each other or do they repel each other? And the other start of statement says, the same poles on a bar magnet either attract each other or repel each other.

So I'm going to give you a few moments now to have a think about how these sentences can be matched up together, and then we'll go through the answers very soon.

Amazing work, everybody.

So let's do a quick recap.

Opposite poles on a bar magnet attract each other.

The same poles on a bar magnet repel each other.

Amazing work so far, everybody.

Well done.

So we're going to move on to the next task now.

So I want you to follow these instructions really carefully.

So we're going to make models of magnets out of paper to help you predict whether they will attract or repel each other.

So place your two model magnets close to each other so that their poles meet.

So we've got two examples here.

Predict whether real magnets would attract or repel each other in this position.

So for your investigation here, to start off with, don't actually use bar magnets.

You may want to use some pieces of paper or card or scrap paper that you have lying around to predict whether the real magnets would attract or repel each other when they are in that position.

I then want you to have a think about how many different combinations of poles can you find.

So pause the video here, maybe have a read of the instructions again to make sure you've got the correct method for your investigation, and have a go at exploring.

And then we'll go through some of the answers very shortly.

You may want to record your predictions in a table like this.

So we have a column of magnet one, another column with magnet two, your prediction, and then we've got one column at the end there that's blank.

But please leave that blank, don't write anything in there.

So in the magnet one and magnet two, you'll write N for north-seeking or S for south-seeking here to show the magnet poles that are facing each other.

So for example, S1, S2, to show that the magnet one is the south-seeking pointing, and for magnet two it's south-seeking.

In the prediction, write attract or repel.

So do you think that these magnets would attract or they would repel? So pause the video here, have a go.

Maybe go through the instructions again just to ensure that you follow the right steps.

Have a go, and we'll talk through the answers a little bit later on.

Then I would like you to test your predictions using a real pair of bar magnets.

So put them into each of the positions and see what happens.

So this is where you're going to use your table to help you.

So this last column here is for the real results.

So you've already made your prediction, and your last column there is to write whether the real magnets attract or repel in the final column here.

So that's where you're going to write the real results.

So pause the video here and have a go.

Amazing work, everybody.

Well done.

So here is an example table.

So for magnet one, we had south one, magnet two, south two, they would repel, and the actual result was repel.

There are some other options here of the different combinations you could have had of magnets and the predictions and the real results.

So well done, everybody, for having a go at this investigation.

So the next part of this task is name these different types of magnets.

Predict what will happen when they are placed close to each other as shown in these diagrams. So there's different types of magnets on the screen here.

So I want you to predict what will happen when they're placed just like they are on the screen there and shown in the diagrams. Then I want you to test your predictions with real magnets and observe what happens.

So when we're observing, we're looking with our eyes to see what happens.

Pause the video here and have a go.

Amazing work, everybody.

So the first diagram here shows bar magnets, and if the magnets were placed like this, the same poles are facing, so they would repel.

So we can see that the north pole and north pole are both facing each other, and the south-seeking pole and the south-seeking pole are also facing each other, so they would repel.

The next set of magnets are disc magnets and opposite poles here are facing, so they would attract.

And the last set of magnets here are horseshoe magnets.

Now the same poles are facing, so they will repel.

Amazing work, everybody.

You've done such a great job so far.

So we've come towards the end of the lesson now, so we're going to do a summary of all of our learning.

Every magnet has two poles, north-seeking, which stands for N, and south-seeking, which can be seen as S.

Opposite poles on a magnet attract each other.

The same poles on a magnet repel each other.

Scientists make predictions based on the results from previous investigations.

Now I just want to say a huge well done to everybody for today's lesson.

We've done some fantastic learning all about magnets, putting them together, and we've really focused on those two key words, attract or repel.

So I hope you have a great rest of the day and I'm sure I will see you in the next lesson very soon.

Bye bye.
