Hi everyone, can you see me above all of these structures? It is so great that you have joined me on our last lesson in this unit.

My name is Miss.

Larham and I am your design and technology teacher for today.

Now we're going to be having a look at all of the structures that we have made throughout this unit.

So can you make sure that everything you've made, you've got close by to you today? Shall we get started? Fantastic, so like I said, this is our last lesson in our structures unit.

So we have made it all the way to lesson than 10.

And remember last lesson, we made a house for one of the three little piggies didn't we? And we had to test it and evaluate it to see if it was strong, stiff and stable.

Now, today we're going to be looking at technical terms. So we're going to be thinking about all of that new design and technology vocabulary that we have learnt and we're going to see if we can locate them, see if we can find them on all of our structures.

So for today's lesson, you'll need a few bits of equipment.

So in this lesson, you will need some paper, a pencil, some scissors, some glue.

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

So if you need to pause the video now and go and collect everything you need, off you go and do that, see you in a second.

Fantastic, welcome back and thank you for collecting everything you need for today's lesson.

Let's have a look at what our lesson is actually 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 be thinking about types of freestanding structure.

Then we'll do our talk task, where we're going to be thinking about those technical terms. Then, it will be your independent learning time, you're going to do some labelling for me today.

And finally all together, we will finish with our exit quiz.

It is intro quiz time and you have been amazing at my quizzes during this unit.

So well done, let's do one question together.

I'm going to ask you to think about a word that Miss.

Larham has been using a lot in this unit.

Can you remember what the word stable means when we're thinking about structures, what does stable mean? Have a few seconds to think.

Do you think you're ready to tell me, it's quite a tricky question isn't it? Do you think, you know what the word stable means? Tell me now, great thinking.

Now, do you remember the word stable means? So it can stand up by itself and it is strong.

And when a force is pushed against it, it doesn't fall over.

So if something is stable, it's really strong, can hold itself up and doesn't fall or break easily.

Well done if you'd remembered about the word stable, that's amazing.

It is time for our star words, and because it is our last star words of the unit, I want you to make sure you're joining in with your big, loud, confident voices.

So remember we do my turn, your turn.

Let's see what the first star word is, structure.

Structure, well done.

We've been using that word a lot this unit haven't we? Shell, shell, well done.

We were looking at shell structures last lesson weren't we? Do you remember shell structures are hollow.

That means we can go inside of them and they are protected with this outer to coating so whatever inside is kept safe and protected.

Frame, frame, well done.

And we've looked at frame structures haven't we? Frame structures are made up of thin components joined together to make a structure.

The next star word is solid.

Solid, well done, we can get solid structures as well.

These are not hollow.

So think about something that has been made fully of concrete for example, or think about a statue that has been made from marble.

They're solid structures, so they're not hollow.

And finally, last one, free standing, free standing.

Well done, we've talked lots about freestanding structures haven't we? And we know that they can stand up strong and stable all by themselves.

Well done for joining in on your star words today.

Now we're just going to quickly remind ourselves of the different types of freestanding structures that we have been learning about this unit.

So can you see this photograph of this huge skyscraper on your screen now.

So this is the freestanding structure, isn't it? It can stand up all by itself and it's very strong and very stable.

Now this big skyscraper would have been made up from a metal frame to start with and then put on an outer coating to protect all of the people inside.

Here's another freestanding structure, a bench.

So this bench stands up all by itself.

And it's strong because it can fit lots of people on there and hold them up without breaking.

Now this has been made up from different components and joined together as well.

So this is a frame structure also.

And finally, do you remember this picture from last lesson? This is a shell structure isn't it? You can go inside of this really cool building and it has an outer covering like a shell, and you can go inside and be protected from anything from the outside.

So there are a few examples of some freestanding structures.

I think you are all experts in freestanding structures now.

So well done I'm for listening so carefully during this unit.

Now it is time for our talk task.

I'm going to let you know what I would like you to talk about with the people around you.

So for your talk task today, you're going to see if you can remember any of our special design and technology words that we have been using in this unit.

These are all technical terms and we've been using them throughout all of the lessons.

So shall we remind ourselves of what they are? Free standing structure, join, base, buttress, centre of gravity and replicate.

So what you're going to do now is you're going to pause the video and see if you can remember what any of these words mean.

Don't worry if you can only remember a few, just have a talk about those.

Okay, so pause the video, have a chat about these words and press play when you think you've got your answer.

Welcome back everybody and well done for having some time to talk about those special technical terms that we have been using throughout this unit.

Now we're going to check to see how close you were.

I bet you've got lots of them right.

So our first technical term was free standing structure.

I bet you can tell me what free standing structure means.

If you think you can, tell me now.

Well done, it's a structure that can stand up strong and stable and sturdy, all by itself.

Well recommended, now do you remember freestanding structures? There are lots of different types of structures within this aren't there.

So they're framed structures and they're made up of thin frame components, all joined together.

We've got shell structures, which are the ones where that have that outer covering and they're hollow inside.

And we've also got solid structures haven't we? They're the ones that are not hollow and we can't go inside and they're very strong and can last a really long time.

So on the screen here, you can see some examples of some freestanding structures.

So you've got the Eiffel tower, we've got a bridge and we've got a table.

They all stand up by themself, well done if you've remembered that.

Our next technical term was join.

I wonder if you can remember the different ways that we have joined our materials together.

Do you remember when we joined two boxes together and we used our tape didn't we? And we made that L shape to join them together.

Do you remember when we had to join our tube to our base and we made cuts in the bottom of the tube or made a bit to go round the tube, so we could easily join this to the base.

Do you remember when we made our frame structures? How we joined our straws together.

Do you remember when we scrunched up a little bit of the end of the straw and we put it inside of the other, and then we wrapped a bit of tape around it.

So that's how we can join our structure materials together.

Do you remember the word base? I remember adding a tower, a structure onto a wider base made it more stable.

So when I had my beanstalk, just putting this on the surface, it was not stable it fell over.

But because I added it on to a big, wide base, when I pushed it, it didn't fall over.

Do you remember we could also use a buttress to make our structure more stable? So when there's a force pushed on it, it doesn't fall over.

And do you remember these two triangular bits on the outside that pushed against the tower? The structure so that again, when it's pushed, it doesn't fall over.

Well remembered, I knew you were going to be great at this.

Centre of gravity was one of our trickier technical terms wasn't it? We needed lots of science knowledge to be able to understand centre of gravity.

Now do you remember, the centre of gravity is where gravity starts to act.

And the centre of gravity tells us how easily the structure fall over.

We want our structures to be strong and stable don't we? So we need to think where the centre of gravity is going to act, to tell us whether it's going to stand up by itself.

And we tried this didn't we, when the centre of gravity was near the top, it fell over really easily.

But when we did the force near the bottom of the tower, it didn't fall over quite so easily did it? You're listening really carefully everybody, well done.

Our last technical term was the word replicate.

Do you remember what replicate means? Having a little think for a moment, 'cause I'm going to ask you to tell me.

Are you ready to share? What do you think replicate means? Thank you for sharing your answer.

Now replicate means we make an exact copy.

So have a look at the legs on this table and on this chair on your screen.

They have been replicated.

So each chair leg is exactly the same.

It's the same height, the same width, the same shape.

And remember, we needed to replicate these parts to make sure that these structures again, were strong, sturdy and stable.

If we made one chair leg this big and one this big, our chair would be wobbling about and it would fall over wouldn't it? Well done everybody for all of those technical terms. Now it is time for your independent learning task.

I'm going to explain what I would like you to do and then it will be your turn.

So for our independent learning task, you will need all of the structures that you have made during this unit.

So if you need to pause the video now and go and collect all of your structures, now's the time to do that.

And you can press play when you're ready, but we will need all of our structures for this task.

You will also need these labels and you can find these labels if you download the worksheet.

Now don't worry if you can't print off these labels, you can make your own.

So you can write down your own little labels, copying the words from the worksheet.

We are going to see if we can cut and stick these labels on the right places on our structures.

So you might like to have a couple of each of these labels because you might be able to label more than one structure.

Okay, so make sure you put your structures and make sure you have got your labels.

And I'm going to show you how we're going to label them.

So I am here with all of my structures and I have cut up the labels I was telling you about.

So what we're going to do now is we can stick these technical terms on our structures in the right places.

So the first label I'm going to look at says base.

Have a look at my structures, can I see a base.

Yes I can, so I'm going to put glue on the back of the label and I'm going to stick it on a base.

I'm going to stick it on this base here.

I stuck that on, I printed another label that says base because I've got another one.

So you can enable more than one structure.

I'm going to put some more glue on.

and I remember on my beanstalk, that we used at base on the bottom.

So I'm going to stick my label on the base.

Can you see that, I'm labelling my technical terms. Let's have another look at one.

I'm going to look at freestanding structure.

Now, who likes a challenge? Who likes to be a really big superstar? I do, now I'm going to set you on a challenge.

Now all of these are freestanding structures aren't they? But I want to see if you can label what type of freestanding structure it is.

So I'm going to label the swing, and I know that that is a frame freestanding structure.

So I've written to word frame on there, so I'm a superstar, I like to have a challenge I'm going to put some glue on there and I'm going to label the swing.

Going to wrap this one round like this, can you see? Got my freestanding structure label on there.

Now what I'm going to do is look at the word replicate.

Now where on your structures, have you made an exact copy of something? So I can see this on my bridge, I've made replicated triangles.

I've also got baby bear's chair haven't I and I replicated the legs and the spindles.

So I'm going to put some glue on here and label everything that I have replicated.

And finally I'm going to think about the word centre of gravity.

Now think about those tall, free standing structures.

So on the butterfly and on the beanstalk, where would I put centre of gravity? This is the same as the join as well, look where you have joined any of your structures together and see if you can label that for me.

So what you're going to do now everybody, is you're going to pause the video and you're going to label all of the technical terms that you can see on your own freestanding structures.

Don't forget my challenge about freestanding structures.

Is it frame, is it shell or is it a solid structure? Okay, have fun, good luck and I'll see you soon.

Welcome back everybody.

Did you manage to label all of your structures with our technical terms? Well done if you did.

I managed to label all of my structures as well.

So I had labelled where components have been joined together.

I have labelled where I have replicated parts.

I have labelled base and buttress and I have remembered to label that they are actually all freestanding structures, that this one is a frame structure.

This one is a frame structure, and so is this one, so I managed to label that as well.

Well done everybody on your independent learning task.

I am so pleased that we know all of these really grown-up words, well done.

We have come to the end of our lesson, but before you go, it is time to do our exit quiz.

Now I've got one big question for you.

We have made lots of structures in this unit, haven't we? But they are special type of structure.

They all stand up strong, sturdy and stable by themself.

So what type of structure is all of these? Can you ever think for me? Do you think you know? Do you think you're ready to tell me what type of structure all of these are? Okay, tell me now, I'm listening.

If you said free standing structure, that's amazing.

Well remembered, that we have been making structures that stand up all by themselves, well done.

Now, if you would like to share a photograph of all of your structures all together, you can share your work with Oak National and that means I get to see all of your work too.

If you would like to please ask your parent or carer to share your work on Twitter, tagging @oaknational and hashtag learn with Oak.

I am super happy that you have been able to join me in this unit all about freestanding structures.

I have loved working with you all.

Thank you so much for working so hard and taking part.

I think you are amazing.

I'll hopefully see you all again somewhere else really soon, bye.
