Lesson video

Hi there.

How are you today? I hope you're all okay.

Thank you so much for opening up your design and technology lesson today.

My name is Miss Larham, and I'm going to be your design and technology teacher.

We have got another busy lesson ahead of us today with lots of making to do.

So it would be a really great idea if we got started straight away.

Today, we are on lesson eight of our structured units, where we've been learning all about freestanding structures.

And last lesson, we made a really, really, really tall freestanding structure, didn't we? And because we made it so very tall, we had to make sure it was stable, so we added a base and a buttress, didn't we? But today, our lesson is all about Baby Bear's chair.

Hmm, do you know of a story that includes a chair for Baby Bear? In a moment, you'll find out if we're thinking of the same story.

Let's see what we will need for today's lesson.

In this lesson, you will need paper, a pencil, some tape, a teddy bear.

I've got mine ready.

And some scissors.

And because I'm asking you to use scissors, make sure you're supervised by a parent or a carer.

So pause the video now, go and collect everything you need, and press play when you're ready.

Off you go.

Thank you for collecting everything you need.

Did you find yourself a teddy bear? Can they say hello to mine? Hello.

Well done.

Let's see what our lesson is going to look like today.

So first, all together, we're going to do our intro quiz, then we will do our star words, then we're going to look at some existing products, then we will do our talk task, and we're going to be doing some designing and replicating today, then it'll be your independent learning time, and finally, we will finish all together with an exit quiz.

It is time for our intro quiz.

And for our intro quiz today, we need to stand up.

So can you stand up for me? Are you standing up ready for me? Well done.

Now, can we put our arms and our legs into a nice narrow shape? Now, wobble around.

Oop, and what do we notice that happens? That's right.

We just fall over.

So your intro quiz question today is to change your body shape to show me how you could become more stable in the wind.

So show me now what you could do with your body to make yourself more stable.

Off you go.

Well done.

I can see that you have to open your legs wide apart.

You have made yourself a wider base so when the wind is blowing, we don't fall over because we are more stable.

Great intro quiz, everybody.

It is time for our star words.

Give your hands a flash for me.

Well done.

Let's make sure we join in today with our big loud voices.

Let's see our first star word, and then we'll do my turn, your turn.

My turn, replicate.

Your turn.

Replicate.

Well done.

If we replicate something, we make an exact copy.

So say if we had one thing and we replicated it, it would have to be exactly the same.

Our next star word.

My turn, user.

User.

Well done.

User means who.

Who is going to use it? So our user today is going to be our Baby Bear.

Last star word.

My turn, function.

Function.

Well done.

The function means, can it do all the things the user needs and wants it to do? So all the things that Baby Bear wants his chair to be able to do, we need to make sure that we have made sure that it meets all of our Baby Bears needs.

Now, we're going to look at existing products, and it's really important that designers look at products that already exist.

So we're going to be looking at chairs.

Chairs that are in our house that we're in now, or in our school, or any places that you have visited.

We're going to think about all of those chairs that we've seen before.

So I have found a chair that was in my home.

I wonder, have you got a chair near you? Or maybe you're even sitting on a chair right now.

Let's have a really good look at a chair together.

If you've got your chair, take a look at it for me.

Take a few seconds to have a really good look at it.

I wonder, can you tell me what material is your chair made from? Have a look.

Can you tell me now? What material is your chair made from? Fantastic.

My chair is made of wood.

Hmm, now I wonder why that material has been chosen for the chair? Have a think why your chair is made from that material.

Wonder why.

I think my chair has been made from wood because it needs to be really strong and stable.

We don't want to sit on a chair and it just bend all the way down, or wobble so we fall off.

I think this material's been chosen because it's hard, and strong, and stable.

Now, can you check for me? How many legs does your chair have? Count them for me.

Tell me, how many does it have? Same.

Mine has four legs as well.

Well done for counting.

Have you noticed that the legs of the chairs are connected on the edges? They're not clumped together in the middle in this bit here.

They're on the outside.

I wonder why that might be.

I wonder so it's when we sit on it, it can take all of our weight.

That is really strong and stable.

I wonder who might use your chair? Can you think of who might the user be? Who would use your chair? Who might use your chair? Can you tell me? That's some really good thinking.

I'm thinking anybody that is a child or older could you use my chair.

I think maybe a baby or toddler might be too small to use this quite big chair.

It's definitely for older children and for adults.

Where is your chair used? Where is it used? Can you think for me? Where might it be used? Can you tell me? Great thinking.

Now, my chair is a dining chair.

So that means we use it when we eat our dinner at the dinner table.

This is a dining chair.

Well done for having a really close look at an existing product, an existing chair.

Great job.

Now, using your paper and your pencil, I would like you to have a look at all of the different chairs where you are now.

And I want to see if you can draw all of those different types of chairs for me.

Maybe you could also remember some chairs when you were out and about at different places.

So what you're going to do now is pause the video.

Using your pencil and your paper, you're going to draw me some different chairs that you have seen before.

Can I challenge you? Can you try and draw four different chairs for me? You can! That's amazing.

I'll see you really soon.

Welcome back, everybody.

I hope you managed to draw me some different chairs that you have in the place you're in now, or chairs that you might have seen before.

I'm going to show you mine now and show you the next job that I would like you to do.

Here are my drawings of some chairs that I found around my home.

I even thought of one that I had in my garden.

Now, what we're going to do is we're going to turn these pictures into diagrams. So that means we're going to add some labels to our pictures.

And we're going to label the legs.

Luh, eh, guh, suh.

Legs.

And we're going to label the seat.

Suh, eeh, tuh.

And we're going to label the back of the chair.

Buh, ah, cuh.

Okay, let me show you.

So I'm going to think, which ones on here have legs? They all have legs.

So where are the legs? Remember, the legs hold up the chair.

So here's a leg, so I'm going to draw a line, and I'm going to write, leg.

Luh, eh, guh, suh.

I could do that on all of my chairs.

And then, I'm going to label the seat.

The seat is where we sit.

So I'm going to label the seat on this one, draw a line.

Eeh, tuh.

I'm going to do that on all of my chairs, and then I'm going to label the back of the chair, the bit where our back would rest if we lent back.

So here's the back of a chair.

I'm going to draw a line.

Buh, ah, cuh.

Okay, but I'm going to label the back on all of them.

So what I would like you to do now is you're going to pause the video, and you're going to label your pictures to turn them into diagrams. You're going to label the legs, the seat, and the back.

And then, press play when you've done that.

Off you go.

Welcome back, everybody, and well done for completing your labelling.

I managed to get mine labelled too.

I even included a challenge label, an extra label.

I labelled the spindle.

Hmm, which part of my chair is the spindle? Do you know? It is these bits here, these cylinder shapes that I quite often find them on the back of the chair.

So these wooden spindles, I have labelled as well.

I wonder if you found any chairs with any spindles.

Now, it is time for our talk task.

Our talk task is going to be on the story, Goldilocks and the Three Bears.

Do you know that story already? Maybe you could join in with me.

Once upon a time, in the forest, in a small cottage, lived three bears.

There was Daddy Bear.

He was a big bear.

He had a big bowl, a big chair, and a really big bed.

And there was Mommy Bear.

She had a middle-sized bowl, a middle-sized chair, and a middle-sized bed.

And then, there was Baby Bear, and he had a teeny-weeny bowl, a teeny-weeny chair, and a teeny-weeny bed.

One morning, when all the bears got up, Mummy Bear made them a nice bowl of porridge for their breakfast.

But when they got their bowl, they realised it was too hot.

So they decided to go out for a little walk.

Off they went.

But skipping through the forest was a little girl, a little girl called Goldilocks.

She had managed to get herself lost in the forest.

She kept walking until she came across a cottage, the bears' cottage.

She thought, "Oh, whoever lives here "might be able to help me.

"I'm terribly lost." So she knocked on the door.

Hmm, there was no answer, so she pushed the door and let herself in.

"What was that delicious smell?" Thought Goldilocks.

She followed the smell all the way to the bowls of porridge.

She was terribly hungry, so she decided to tuck in.

She first started to eat Daddy Bear's porridge.

"Oh, oh! Too hot," she said.

So she tried Mummy Bear's porridge.

"Ugh! Too cold," she said.

So she tried Baby Bear's porridge.

"Mmm.

Just right." And she ate it all up.

Now, she was full and needed a sit down, so she went over into the living room to see if she could find somewhere to sit.

She tried out Daddy Bear's chair.

She got on.

"Oh, this chair is way too big." So off she got.

She tried Mommy Bear's chair.

She got on.

"Oh, this is still too big." So she got off and tried Baby Bear's chair.

She sat down and thought, "Oh, this is just right." And started to get herself comfy.

When all of a sudden, crack! Bang! The chair broke.

Goldilocks had broken Baby Bear's chair.

Baby Bear is going to be so upset to see that his chair, his favourite chair has broken.

Goldilocks went upstairs, away from the chair she had just broken.

When Baby Bear arrived home, he saw that his favourite chair had been broken, and he was terribly, terribly upset.

And he wondered, "I'm going to need a new chair.

"Who can make me a new chair?" And I said, "Don't worry, Baby Bear.

"I know lots of really great helpers.

"I bet the children who are watching this video now "will be able to design and make you a brand new chair." Shall we do some talk time to see what we need to think about when we're designing and making a new chair for our Baby Bear? Okay, so what you're going to do now is you're going to pause the video and you're going to have a talk.

What do we know about Baby Bear? How big is Baby Bear? What does Baby Bear want the chair to do? Why does Baby Bear want a chair? So can you pause the video and have a talk about all those questions for me? Don't forget to press play when you're ready.

Welcome back, everybody, and well done for having a talk about what we already know about Baby Bear, and what he might like his chair to be like.

Now, we're going to get started with our design for our Baby Bear, and then we're going to do some replicating.

So let me show you how to design, and then it will be your turn.

So I've got myself some paper and a pencil, and I'm going to draw the chair that I want to make for Baby Bear.

So I'm going to think about the parts that I'm going to use to make my chair.

So I'm thinking I'm going to use some of my cylinder shapes as the chair legs.

So I'm going to start by drawing the cylinder shapes.

And then, I was thinking that Baby Bear needs a seat, so I'm going to use some of my card to make a seat.

Now, I want to make sure that Baby Bear has a back of the chair.

So I think I'm going to use some of my longer cylinders to make some spindles on the back of the chair.

They're going to be longer and thinner than my chair legs.

And then, using a bit more of my card, I'm going to join these together at the top.

So I've got my cylinder chair legs, and I'm going to label that, cylinder.

How many of these do you think I will need? How many chair legs are there? Four.

That's right.

So I'm going to put that in a circle, and I'm going to label the seat is card, and then I'm going to label the spindles.

And I need one, two, three, four, five of those.

And I need some card for the back of the chair.

So what I would like you to do now, you're going to pause the video, and you're going to draw a chair that you want to make for Baby Bear.

Make sure you label the parts, what you will make them out of, and remember to think about how many of each part you will need.

Then, press play when you have done that.

Off you go.

Welcome back, everybody.

I hope you managed to finish off your design for Baby Bear's chair.

Baby Bear was wondering if you'd be able to hold it up so he could have a look.

Hold up it up now.

He's coming to see.

Huh.

Baby Bear said they're amazing.

Now what we need to do, everybody, is we need to make our chair legs for Baby Bear's chair.

Now, when we do that, we need to make sure we replicate the chair legs.

So that means, when we make one chair leg, the other three chair legs need to be exactly the same.

Why do you think all of the chair legs need to be exactly the same? So exactly the same size.

Why do you think we need to get them all exactly the same size? Have a think.

Well done for having a think.

I wonder what you came up with.

If all of our chair legs are different size, when we attach them to the seat and we put it down, some of the chair legs might not touch the floor, and that means the chair will be really wobbly.

Baby Bear, do you want a wobbly chair? He said, "No way! No, thank you." He wants a stable chair.

So we need to make our chair legs now.

Let me show you how.

So now, we need to replicate the chair leg so all four chair legs are exactly the same.

So I need to make sure that my card pieces for my cylinders are exactly the same size.

So what I'm going to do is I'm going to fold this paper in half and cut it out using my scissors safely.

I'm then going to do the same with the other piece of card.

So this is going to help me to make sure that all of my chair legs are exactly the same size.

So now, all of my bits of card are exactly the same size.

So now, I'm going to roll these up, and I'm going to make sure that when I roll them, they're going to be all the same size.

So do you remember when we did this before? So we rolled it up and then we add on a bit of tape.

So let me get some tape ready on my table and roll it up.

Little tap.

Make sure it's straight, add on the tape.

Going to add on a little bit more so the tape goes all the way down.

Okay, so I've made one of my chair legs.

Now, what I'm going to do is do that three more times so I have four chair legs all this size.

It's your turn to make your chair legs now.

Off you go.

Welcome back, everybody, and I hope you managed to replicate your chair legs.

So you just need to check that when you hold all of your four chair legs together, that they are exactly the same size.

That's really important for a stable chair.

Now, it's your independent learning time, and we're going to put the chair together.

I'll give you a few clues of how to get started, then it'll be your turn.

So now, it is time to assemble our chair.

So put it all together.

And remember, we know how to attach cylinders to a base, don't we? Do you remember when we made this fan shape using our scissors? That's the technique I'm going to use for my chair legs.

So I'm going to cut some snips, some little cuts, up the bottom of the chair leg.

Then, do you remember we can fan them out like this? Okay, and then we put some glue on them, and we can stick it to the base.

Now, this is the chair leg and I'm sticking it to the seat.

So what I would do is attach all four of the legs in the same way to make sure that the chair has something to sit on.

Then, do you remember, as part of my design, I had a back to my chair, didn't I? So I had some spindles along the back.

So I'm going to stick those on as well using the correct fixing technique, and then I've got the back bit of chair as well that I will stick on.

So your job now is to put your chair together.

Have fun, good luck, and don't forget to press play when your chair is completely finished.

Welcome back, everybody, and I hope you managed to make your chair for your Baby Bear.

Now, I wonder, did you manage to attach all of the replicated chair legs? And when you push down on it, is it sturdy? Is it stable? Does it push over? So that's one thing you can check.

Can you check that for me now? Put some weight in the middle, give it a little push to make sure it doesn't fall over.

Do it now.

Well done if you have made a stable and sturdy chair.

That's awesome design and technology work.

Now, there was a little challenge, wasn't there? To see if your chair could fit your Baby Bear.

Now, let's see if it fits my Baby Bear.

Yay! So the chair holds his weight.

He has plenty of room for his bottom and his legs, and the back is as tall as him.

I bet that's really comfy, isn't it, Baby Bear? I think it must be.

Can you see if your Baby Bear fits on your chair? See if you managed to do that challenge.

Well done if you can fit your Baby Bear.

Don't worry if you can't.

Maybe you could try another one at another time.

Amazing work, everybody.

I love that you have made a working chair today.

Well done.

It is time for our exit quiz.

Now, I'm going to head over to my chair to see if you can tell me where the legs, the seat, and where the back is.

I'm going to go over there now.

Now, I'm going to point to a part of my chair, and you're going to tell me, is it the legs, is it the seat, or is it the back? Are you ready? I'm going to point to here.

Legs, seat, or back? Few seconds to think.

Ready to tell me? Well done, it's the seat.

Good job.

Next one.

Seat, legs, or back? Which one? This bit here.

You ready to tell me? It's the legs.

Well done.

And lastly, I'm going to point to this bit.

Is this the legs, the seat, or the back? Few seconds to think.

You ready to tell me? Okay, tell me now.

It's the back.

Of course, it is.

Well done.

Now, can anybody remember what these bits are called? I gave them a really special name, didn't I? Can anyone remember what they're called for a bonus point? Tell me now if you think you know.

What? How did you remember that? That's amazing.

These are called spindles.

Amazing exit quiz, everyone.

Now, we have come to the end of another really fun lesson all about structures.

Now, if you would like me to have a look at that Baby Bear's chair that you have made today, you can share your work with Oak National, and that means I get to see the amazing chairs that you have made today.

If you would like to, please ask your parent or carer to share your work on Instagram, Facebook, or Twitter, tagging @OakNational and #LearnwithOak.

We have got another busy lesson next time, so I really look forward to seeing you then, everybody.

Bye!.
