Hello everybody.

Thank you so much for opening up your Design and Technology lesson today, it makes me super happy that you are able to join me.

My name is Miss Larham and I am your Design and Technology teacher.

I was wondering, would you guys tell me what your name is? Fab, tell me now.

Lovely, it is so great to meet you.

We've got another really busy lesson ahead of us today with lots of practical making today.

So we're going to get started right away.

So today we are on a Lesson 9 of our structures unit, where we have been learning all about freestanding structures.

And do you remember the last lesson we made a special free standing structure for our teddy bear, didn't we? Because the chair broke.

So we had to make a new chair for baby bear, and we looked at replicating parts, didn't we? Now today we're going to be learning about strong, stiff and stable.

Today is going to be a practical lesson where we're going to be doing lots of making.

So let's see what equipment you will need for today's lesson.

In this lesson, you will need; some paper, a pencil, some tape, some modelling materials.

Now modelling materials are things that you can find in and around the place that you are in now, you could even go outside if you could.

And there are materials that we can use to do some building.

So you might have some tubes.

You might have some empty cardboard boxes.

You might have some plastic containers.

You might use some of your building blocks from other lessons.

You might have some paper straws or lolly sticks, or wooden sticks or even sticks that you can find outside, and things like card as well.

So you're going to need some things some around where you are now to be able to do some modelling, some building today.

And finally, you will need some scissors.

And remember, because I'm asking you to use scissors today, you need to be supervised by a parent or a carer.

So what I would like you to do now is pause the video and go and collect everything you need for today's lesson.

Then press play when you're ready, off you go.

Brilliant.

Welcome back and thank you for collecting everything you need for today's lesson.

Now, as you're doing your making activities today, when you're doing your building, you might think, Oh, I really need this or I really need that, and that's okay if you need to go off and find some more modelling materials for your idea.

Now let's take a look at what our lesson is going to look like today.

So first altogether, we're going to do our intro quiz.

then it will be star words time, then we're going to look at houses from around the world.

Then we're going to do our talk task.

Then it'll be your independent learning time.

Then we're going to do an evaluation today and finally to finish all together, we will do our exit quiz.

It is time for our intro quiz quiz.

And for our intro quiz today, I'm going to show you a photograph and you're going to help me label it.

Let me show you.

Are you ready to see my photograph? Let's see.

So it is a photograph of a chair, and we were learning all about chairs last lesson, weren't we? So your special job for me today is see if you can label my chair.

So in a moment you're going to see an arrow point to part of the chair, and you're going to tell me what it's called.

Are you ready? Here's our first arrow.

Hmm, what was this bit called? If you're not sure it started with the letter L.

Do you think? Are you ready to tell me, tell me now.

Fantastic, if you said leg, well done its the chair leg, isn't it.

Let's see what's next.

Do you remember what this bit was called? Mm, the bit where we sit.

It began with a S.

A few seconds to think, are you ready to tell me, tell me now.

If you said seat well done, this is the seat, that's the part where we sit on and the last arrow.

Do you remember what this bit was called? It starts with a Ba if you're not sure.

Three seconds to think.

You're ready to tell me now? Tell me.

Well done, if you said back, good job it is the back of the chair, so we have the leg, the seat and the back, amazing helping, thank you for labelling my chair.

It is star words time, can you give your hands a little flash.

Well done, can you give them a big flash, super.

Remember on star words we do my turn then your turn and I want you to use your big loud voice for me today.

Our first star word is, my turn evaluate.

Evaluate.

Well done, so we're going to judge to see if we've done a good job, to see what we've built today, to see whether it works or not.

Our next star word is fit for purpose.

Well done, that was long, wasn't it? My turn, fit for purpose.

Well done, and what we build today, we're going to check to see if it work how we want it to work.

Our next star word is my turn, sturdy.

Sturdy.

Well done, sturdy means is it strong? Is it stable? It's not going to fall over, is it? We need to check that what we make today is sturdy and strong and it doesn't fall over.

Our last star word for today is shell structure.

Well done.

Shell structure.

Fantastic joining in.

I'm going to tell you a little bit about shell structures now.

Can you see that picture in the really cold place? Can you see that igloo? Have you ever seen an igloo before? Have you ever been inside an igloo? Can you see that cardboard box in the middle? And have you ever been in a building that has got a cover on it to keep us dry inside? If you have seen or been in any of these before, you have been in a shell structure.

Now a shell structure is often hollow, which means we can see through it, there is nothing on the inside.

Now a shell structure also can hold itself up.

So these three things you can see in your screen, they all hold themselves up don't they? They usually have something inside of it and they are protecting something that's inside.

Just like a house, isn't it? Where we have this structure around us and this space on the inside, isn't there? And it's protecting us, it's keeping us warm and it's keeping us dry.

That is what a shell structure is.

Cool, hey.

Now we're going to be thinking about houses from around the world.

Now houses are cool structures, because they're made up of different types of structures.

So you might see some frame structures, some shell structures, even some solid structures all in one building.

So they build frames for the walls and the roof, and then they cover it with bricks and tiles on the outside, making it a shell structure, to protect everybody that's inside the house.

Now we're going to be thinking about a story.

And I think it's a story you might know.

And it includes three types of houses.

Can you guess the story? Let's see if you're right.

Now we're you thinking of the story, The Three Little Pigs? Do you remember the story of The Three Little Pigs? You might've heard of it before, but don't worry if you haven't because I'm going to tell you this story now.

So once upon a time, there were three little pigs, they lived in a very small house with their mother.

And one day the three little pigs mother said, "Oh, you have all got too big for my little house.

You need to move out and you need to build your own houses." So the pigs connected up their belongings and set off on their way to build their very own houses.

Now, the first little pig came across a farmer who was selling some straw.

So this little pig said, "Farmer I would love to build a house from some of that straw, please can I have some." The farmer said, "Sure," and handed it straight over and this little pig began to build his house from straw.

The second little pig was strolling along and came across a wood cutter who had lots of sticks and twigs.

And this little piggy said, "Wood cutter, I'm ready to build my house.

I would love to build my house from those sticks and twigs that you have there, please can I have some." The woodcutter said, "Sure," and handed them over.

And that little pig started to build his house on sticks and twigs.

Now the third little pig, he was the clever pig, and he came across a builder, a builder who had a stack full of bricks.

And this little piggy said, "Hey builder, can I have some of those bricks you've got there, I need to build myself a home?" So the builder said, "sure." And handed over the bricks to the little pig.

And this little pig started to build his house of bricks.

Do you remember that story? We haven't quite finished it yet, have we? We'll get to the end of the story later.

So the first pig built his house of straw, the second pig built it out of sticks and twigs, and the third pig built his house of bricks.

Before we move on, I'm going to see how carefully you were listening to the story of the Three Little Pigs.

And I've got some multiple choice options that you're going to choose from, here's the question.

Which material did the pigs not use to build the house? So which one didn't they use? Was it option one, straw, option two, sticks, option three, jelly, or option four, bricks.

So which one did the pigs not use? Have a few seconds to think.

So not straw, not sticks, not jelly, bricks, which one did they not use? Are you ready with your answer? Can you point to it on your screen? Which one did they not use, point to it now, let's see if you're right, it's going to have a pink box around the right answer.

If you've got your finger on jelly, well done, the pigs didn't use jelly to build their house, did they? That wouldn't be very strong and sturdy and stable would it? Be very wobbly.

Now it's time to our talk task, so let's see what I'm going to ask you to have a chat about with the people around you.

So for our talk task today, I want you to talk about choosing a suitable material.

So I would like you to analyse the materials that the three little pigs chose to build their home.

Remember straw, sticks and bricks.

What makes them good or bad.

They're building a sturdy, stable house.

And sturdy means, it stands up by itself, really strong, doesn't break, doesn't fall over.

So you're going to pause the video now and talk about what makes them good or bad building materials.

Then your going to press play when you have your ideas, off you go.

Welcome back everybody and well done for having some talk time.

I wonder what did you think about the materials? Which ones were good? Which ones are bad? Which ones make the best structure? The one that is strong and sturdy and stable.

I wonder which one did you think was the best? We're going to think about that learning we've just done now, and we're going to do our independent learning tasks.

I'm going to get you started and then it will be your turn.

So everybody, what I would like you to do today, is see if you can build me a house for one of the three little piggies.

I want you to use all of your modelling materials that you have managed to find, to be build me a house for one of the little piggies.

Now don't forget this house needs to be strong and stable and sturdy, we need it to stand up all by itself and we don't want it to fall over.

For example, if a big bad wolf came and- blew at it, we don't want it to fall over, do we? So I want you to have a think about all of the learning that we have done in this unit.

Think about what you know about frame structures and joining materials together.

Think what you know about faces and buttresses to make sure that this house does not get blown over.

So your job now is to pause the video and build me a house for the piggies, that is strong, sturdy and stable.

Then make sure you press the play, because we're going to evaluate it to see if it is sturdy.

Good luck everybody, have fun, see you soon.

Welcome back everybody.

I managed to get my house ready for my little piggy.

And I decided to make my house from straw.

Just like the first little piggy did.

I'm just going to pop him inside.

Is your house ready to be tested? Is it ready to be evaluated to see if it's strong, sturdy and stable? Let's see how we're going to do that.

Do you remember the rest of the story of the three little pigs? So after the pigs had finished building their houses, they were all super proud of themselves and went inside to have a rest.

Little did they know, along through the forest came a big bad wolf who was feeling very hungry and wanted some pig for his dinner.

He came along to the houses and knocked on the door.

"Little pig, little pig, let me come in." And the pigs replied, "Not by the hair on my chin." The wolf said, "Well, I'll huff and I'll puff and I'll blow your house down." And that evil wolf, he blew and he blew.

Now the wolf is coming to pay us a visit, he's going to see if he can blow down our houses.

I think they're strong and stable.

Shall I show you how we're going to test it? So do you want to see the big, bad wolf? Here he comes.

There he is, and he wants some pig for his dinner.

So he's going to huff and he's going puff, to see if he can blow the house down, hopefully he won't be able to, because we have built a strong, a sturdy and stable structure.

So I'm going to test it out now and see if he can blow it down, are you ready? He could not blow down this little piggies house, because I have made it strong and sturdy and stable.

So what you're going to do now is you're going to evaluate how strong and sturdy and stable your house is.

So you might use your breath, you might, huff and puff or if you've got an adult to help you, you might be able to use the hairdryer to see if you can blow the house down.

So you're going to pause the video now and test out your house, but don't forget to press play when you're ready, have fun, good luck.

Well, what happened, did that big bad wolf manage to blow down your house, if he did, don't worry, you can solve that problem now, can't you? You can probably add in a stronger frame structure or a stronger shell structure to make sure he can't blow it down.

If he didn't manage to blow it down well done you have built a strong and stable structure today.

Now, before you go, it's time for our exit quiz, and I've got one question for you.

Can you see that I've got the photographs on your screen, the photographs from the beginning of the lesson.

Do you remember? These are a special type of structure.

Do you remember what that structure is called? The one where we can go inside because it's hollow, the one where it protects whatever's inside, the one with all that outer coating.

Do you remember what it was called? I'll give you a clue.

It starts with a sound sh.

Do you think you know? Do you think you're ready to tell me the name of this structure? Fab, tell me now.

If you said shell structure well done.

These are all types of shell structure.

They protect something inside.

Well done.

Now, if you would like me to have a look at the house that you made today, you can share your work with Oak National, and that means I get to see it.

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

Thank you for all your hard work today, I had great fun and I hope you did too.

I can't wait to see you in Lesson 10.

Bye everyone.
