Hello everybody, Miss Larham here.

How are you today? I hope you're well.

Welcome to today's Design and Technology lesson.

This is lesson two of our mechanisms journey.

I am so pleased that you have been able to join us.

And I really hope you enjoy today's lesson.

Let's have a look at what we are going to be learning all about today.

Today, we are going to explore and evaluate products with moving parts.

And we're going to go on an exciting treasure hunt around our homes to see if we can find some products in our home with moving parts.

Let's have a look at what we will be covering in today's lesson.

First, we're going to start with our star words.

And then we're going to do our start of lesson quiz.

And we're going to do this all together.

We're then going to have a look at the different types of movement.

And this is where we're going to go on our treasure hunt.

Then we're going to use our skills in our practical activity.

And finally, all together, we will do our end of lesson quiz.

Okay, let's have a look at what equipment you will need for today's lesson.

So you will need some card.

Now, the card I'm going to use today is from my cereal packet.

So you might like to find some junk modelling around your house and use some of this as your card today.

Of course, you're more than welcome to use some card that you can buy from the shops.

You will also need to use some scissors today, so make sure you've got a grownup supervising you when you use these.

You will also need a ruler and a pencil, and you might need some tape today.

So you might have to choose whether you'd like to use tape when you do the practical activity later.

And you'll need a special equipment today, you will need to have some paper fasteners as well.

Okay, so if you need to pause the video and go off and collect these, now's the time to pause.

And then you can press play when you're totally ready.

Okay, off you go.

Okay, now, it's time to do our start of the lesson quiz and we're going to do this all together.

So I'm going to ask you a couple of questions and you're going to tell me, you're going to tell your screen what you think the answer is.

Are you ready for my first question? Me too, so if we need to draw a straight line, what piece of equipment will we choose to draw a really straight line? Have a few seconds to think.

And when you've got your answer, tell me, tell your screen.

Brilliant, did you say a ruler? Excellent, I knew you would choose the right piece of equipment.

This helps us to draw our straight line.

Some of you might've said you need a pencil as well.

You are absolutely right.

So when we're drawing our straight lines, we must collect our ruler and our pencil to draw a straight line.

What a brilliant start, well done, everybody.

Are you ready for the next question? Now, we have to think back to last lesson.

So last lesson we made two different types of mechanism.

Here is one of them.

Now, can you remember, is this a slider or a lever? Have a moment to think, slider or lever? Now, can you tell me your answer? Fantastic, it is a slider.

It moves from side-to-side in a straight line.

That's amazing, remembering from last time, well done.

Now, our last question, are you ready? It's looking at one of our other mechanisms from last week.

Now, this one, this one is a lever, and it moves side-to-side in a curved motion.

But my question is can you remember what this bit here is called? I'm going to give you some clues.

Is it called a point or is it called a pivot? So have time to think, is this a point or is it a pivot? Have a second to think.

Brilliant, now, can you tell me your answer? Excellent, you're right, it's the pivot.

And it's holding our bits of equipment together, and it helps to make the movement.

That's amazing, remembering from last lesson.

Well done, everybody, that's great.

Okay, now, it's time for our star words.

And when I go like this, it's my turn.

And when I go like that, it's going to be your turn.

So let's have a practise at saying the word star word.

So I'm going to go first.

And I'm going to say it in my quiet voice.

And then you're going to copy, so it will be my turn first.

Star words, star words, your turn.

Fantastic, now I'm going to say it in my loud voice, are you ready? Star words, star words.

Excellent, amazing copying.

Now, let's have a look at what our star words are for today.

So our first one is mechanism.

My turn, mechanism, your turn.

Brilliant, mechanism.

Excellent, our next one.

Slider.

Slider.

Brilliant copying, well done.

Next one, lever.

My turn, lever, your turn.

Fantastic, I bet you recognise some of these star words, don't you? Next one, movement.

Movement.

Brilliant, next one, rotate.

My turn, rotate, your turn.

Brilliant, that's a new word for today.

Our next one is backwards, forwards.

My turn, backwards, forwards.

Excellent, we've got one more, straight, your turn.

Straight.

So there are our star words for today.

And like I say, you might recognise some of those from last lesson and some of them are new for today.

But don't worry if you don't know any of them because as we go through the lesson, we will talk about all of them.

And by the end, you'll definitely be an expert.

Let's move onto the next part of our lesson, where we're going to be looking at all of the different types of movement.

But before we do that, I just want to do some remembering, do some recap so we know that we're ready to start.

If you remember, last lesson, we learned what a mechanism was and we used our pair of scissors to help us.

So just to remind you, a mechanism is where materials or components are connected to make movement.

And do you remember? We had a pivot here that connected those two bits of material together.

And with that pivot, we're able to use some movement.

So a mechanism today is where any bits of material are joined together and they make some sort of movement.

So we need to remember that to help us with our treasure hunt later, okay? Now, we're going to look at four different types of movement.

Are you ready to find out what they are, the four types? First one, moving in a straight line.

Can you copy with your finger? Straight line.

Straight line, excellent.

Our next one, we can move in a straight line, but we're going to go backwards and forwards.

Hold up your finger, backwards, forwards, well done.

So we've got two so far, let's see what's next.

Oh, the next one moves round and round.

It can rotate, show me your finger.

Round and round, it can rotate.

Excellent, our last movement is a curved motion.

Oh, we learnt that one last time with our lever, didn't we? So use your finger showing me a curved motion.

Excellent, we're going to do all four quickly.

Show me your finger.

Excellent, straight line, go.

Brilliant, straight line, backwards and forwards.

Super, round and round, it can rotate.

Amazing, last one, in a curved motion.

Now, I want you to take a pretend photograph of this screen because we're going to need this knowledge for the rest of our lesson.

Get your camera ready, take a picture.

Excellent, we're going to need to remember this so make sure you take that photograph.

Excellent, well done everyone.

Okay, now, we know our four types of movement.

We're going to think about those types of movement in our mechanisms. So I want you to remember back to last lesson when we looked at sliders and we talked about the way a slider moves.

Have a little think for a moment.

How does a slider move? If you're struggling, I'm going to give you a clue on your screen.

Are you looking? Can you remember? Brilliant, can you tell me now or show me using your finger how a slider moves? Fantastic, you are absolutely right.

A slider can from side-to-side in a straight line.

You can also move up and down in a straight line.

So thinking back to the four movements we've just learned, a slider can move forwards in a straight line, it can also move forwards and backwards in a straight line and go side-to-side, or it can go up and down.

Now, let's have a think.

Where might we find a slider in our home? And there's a clue on this picture here to help you.

That's right, our curtains.

If you have curtains in your house, you can slide them open and closed.

I'm going to show you some in my home.

Okay, so here are some curtains in my house.

And when I pull them, they're a slider.

They move in a straight line forwards and backwards.

And it opens and closes the curtain.

Okay, let's see how much remembering you have done so far, thinking about our four types of movement and our mechanism.

So I've got a question for you, are you ready? Excellent, which of these shows the movement of a slider? Option one, this one.

Option two is this one.

And option three is this one, so can you point to your screen, which one of these shows the movement of a slider? I'm going to give you to the count of three, you ready? One, two, three, have you got your finger on the answer? Excellent, let's see if you're right.

Fantastic, it was option one.

A slider can be side-to-side, forwards and backwards in a straight line.

I've got a challenge question for you.

It can be side-to side in a straight line, but can you tell me which other way can it move as well? Tell me.

Excellent, it can move up and down as well.

Amazing listening, everybody, well done.

Okay, now, we're going to look at the movement of a lever.

I've got the picture on the screen to help you to remember.

Can you remember from last lesson, what movement does a lever make, do you think? Can you maybe use your finger to show me? Excellent, you are right.

A lever can move around a pivot.

And we can move it in a curved motion.

You were probably showing me this with your finger.

Well done, but did you know we can also rotate a lever as well? We can move it round in a full circle, can you see? Okay, get your finger ready to do it with me, ready? So we can move it in a curved motion, we can do it this way, or we can do it this way.

Or it can rotate, go all the way around, show me.

Go the other way.

Excellent, now, let's have a think about a lever moving in real life.

Can you see this picture that I've got here with a car? I'm showing you some windscreen wipers.

They're a lever.

They're a mechanism that works in a curved motion.

And I'm going to show you some working.

Okay, now, we're going to have a look at a lever mechanism working in real life.

Can you see the windscreen wipers on my car? Can you see the movement that they are making? That's right, they're moving in a curved motion, side-to-side.

And down here is the pivot, holding the components together, making the mechanism work, making the lever move side-to-side in the curved motion.

Now, let's take a moment to see how much knowledge we have locked into our brain.

I've got another question for you.

Let's see how you get on.

Which of these shows the movement of a lever? Now, I'm trying to trick you out.

There is more than one answer today.

You have to use two fingers and point to two answers.

So which of these shows the movement of a lever? See if you can point to the two answers, off you go.

Have you got your fingers on ready? Excellent, let's see if you're right.

Fantastic, you are right, it's option two.

It can move round, it can rotate.

And it was also option three.

It can move in a curved motion.

If you got those right, you are a superstar.

Your listening and your thinking is amazing, well done.

Now, it is time to do our mechanisms treasure hunt that we're going to do around our homes.

So I'm going to show you an example now of how to fill out the sheet for our treasure hunt.

You can find this sheet if you open up the worksheet and print it off.

Now, I've done the first example for you.

So this first column here says, "What did you find?" So in my house, I found some curtains.

So I wrote this here.

Then in the next column, it says, "Draw a picture." Now, I haven't done a detailed drawing.

I've just done a really simple drawing of my curtains.

And then I've recorded what type of movement did it have? Was it a straight line? Was it backwards and forwards? Did it rotate or did it curve? I've drawn some arrows to show.

I've also written my idea, so I've written straight line.

Now, the next thing that I found in my home were my scissors.

So in this box here, I'm going to write scissors.

And I'm going to draw a very simple picture.

Just like that.

Not a really detailed one, just a simple one.

Now, I'm going to draw or write what type of movement it had.

So when I open and close my scissors, I can see that they're opening in a curved motion.

I'm going to write that word as well, okay? So you would carry on filling in this sheet.

See if you could find me six examples all together of things that move in your home.

So record what you found here.

Draw me a very simple picture.

And tell me what type of movement did it have, okay? So now, you're going to pause your video, go on your exciting mechanisms treasure hunt.

And then you're going to press play when you have filled in all of these boxes.

Good luck, have fun.

Brilliant, I hope you enjoyed your treasure hunt.

Let's see if we can compare some of the things you found in your home with some of the things that I found in my home.

So I'm going to show you some things, and you're going to compare to see if you found those as well.

I found an example of a slider on my toaster.

So when I push this down, it pokes up the metal bits at the top.

I found some more examples of some sliders in my kitchen, my kitchen drawers open and close.

They go in a straight line, forwards and backwards, to open.

I found an example of a lever in my bathroom.

If I lift up this bit, the water comes out, that's a lever.

Now, can you tell me two of the things that you found in your home? Wow, that's fantastic.

It sounds like you found some fantastic products that have movement in your home, well done.

Okay, now, it is time to do our practical activity.

We're going to see if we can make a model of one of the mechanisms that you found in your home today.

So I'm going to use my scissors as an example of a mechanism that I found in my home today.

So I'm going to just show you how we can make a model of that.

Okay, for this activity you will need to make sure you have all of your equipment.

So you need your card, your scissors, your pencil, your ruler, your paper fastener, and do you remember last week we needed something squishy and squashy to help us to put our paper fastener in safely? So if you need to go and collect everything that you need, pause the video now and press play when you're ready.

Fantastic, well done for collecting everything that you need.

So remember like last time, we're going to just put everything to the side to make sure we have the space that we need in front of us.

Okay, now, as I said, I'm going to make a model mechanism of my scissors.

So I'm going to have a look closely at my scissors and then think, how am I going to make the components? Where am I going to join it with my pivot to make sure that I have the same open-and-close mechanism that I can see here? So I can see that there's, this is made up of two components.

We've got this bit here and this bit here.

So I'm going to start by making two card strips.

Can you tell me, if I'm making a card strip, which piece of equipment do I need to make sure I'm drawing a straight line? Can you tell me now? You're right, a ruler and a pencil.

So I'm going to make two cards strips.

And I'm going to make sure that they are the same width across the bottom.

So today, I'm going to go with three centimetres again.

And I'm going to use the full length of my card.

I'm going to do two of those.

I'm going to measure another three centimetres across the bottom, and draw a straight line up there.

And I'm going to cut these out safely using my scissors.

So you might need an adult here to supervise that you are cutting safely.

So I'm going to cut off those bits that I don't need.

Put those bits to the side.

Then I'm going to cut these apart.

I've got my two card strips.

Now, I'm going to look at my scissors again.

I'm going to look at the mechanism that I'm going to copy.

I'm going to see, now, I've got one going this way.

And one coming that way.

I need to find out where am I going to put my pivot to make sure I can have that open-and-close movement? I think I'm going to go for somewhere in the middle.

So remember when we make holes in our card with our paper fastener, we put our blue tack underneath, squash it down and poke the pencil through.

I'm going to do that in the middle of my other one as well to replicate the scissors.

And then I'm going to put my paper fastener through.

Do you remember, then I turn it back, and this is where you need to be very careful again, open up your paper fastener.

And do you remember last time I said, give a little twist and a little turn to make sure you've got some really fluid movement when you open and close it? So I've now made a pair of scissors.

Chop, chop, chop.

Let's see if they're the same, open and close.

Let's see my mechanism, open and close.

So I have made a model mechanism of my pair of scissors.

Now it's your turn.

Can you make a model of something that you found in your home? It doesn't have to be scissors.

It can be any mechanism that you found.

You're going to pause the video and go off and make your model.

And press play when you are ready, off you go.

You have now made a model of one of the mechanisms that you found in your home today.

Can you show me your mechanism working? So I'm going to show you mine, my model scissors.

Can you show me yours working? Fantastic, look at all the skills you have used today to make your model.

That is just fantastic, well done.

Finally, we have come to the end of our lesson and it is time to make sure we have locked in all of that new knowledge from today.

So all together, we're going to do an end of lesson quiz and you're going to tell me what you think the answer is.

Okay, you ready? Brilliant, okay.

So here is a mechanism called a slider.

Now, can you tell me, can you tell your screen, you might like to use your finger or you might like to use your words, I don't mind either way, can you tell me the type of movement that a slider makes? Off you go.

Fantastic, did you show me or tell me that it moves in a straight line or it can move forwards and backwards in a straight line? I thought you did, well done, that's excellent.

Our next question, today we have looked at some different types of movement.

Can you remember how many different types of movement there were? Can you tell me the number or show me on your fingers? How many different types of movement have we looked at today? Fantastic, there were four different types of movement, so well done if you told me four, that's amazing.

And our final question, and it's a challenge question.

It's a tricky one.

Can you show me with your finger or can you tell me with your words one of the types of movement that we have learned today? Off you go.

Excellent, let's see if you chose any of the ones that we've looked at today.

So did you go in a straight line? Did you go forwards and backwards in a straight line? Did you rotate or did you curve? If you did any of them, you are a superstar, that's amazing.

You have shown me or told me one of the movements from today.

Well done for completing another Design and Technology lesson.

And I can't wait to see you next time, see you.
