Hi there, my name is Mr. Booth and I'm here today to teach you Design and Technology.

Today's lesson is called "Disassemble products to inspire ideas," those wonderful creative ideas that we come up with.

This is part of the "Levers and sliders: moving cards" unit.

Let's have a look at what you're gonna be doing today.

So, today's outcome.

I can disassemble products to create a design specification.

There are some fantastic words in that, isn't there? Should we have a look at some of those keywords? So let's do these keywords together, 'cause there's some quite complicated ones in there.

The first one isn't complicated, though, you should know this one.

But let me do it first, my turn.

Greetings card.

Your turn.

Very good, now of course you all should know what a greetings card is, and I bet you received one of these or hopefully loads of these on your last birthday.

But a greetings card is a card that shares a special message with somebody else.

Okay, next keyword.

User, your turn.

Excellent.

Now in design and technology, the user is very important.

This is who we are designing our products for and we should always have a user in mind when we are designing.

Next one, my turn.

Disassemble.

Your turn.

Brilliant pronunciation, so disassemble means taking something apart to see how it works.

Have you ever taken something apart to see how it works? Okay, final keyword, design specification.

That's quite tricky to say, let's see how you get on, your turn.

Very good, that's excellent.

A design specification describes what a product has to do.

It's a little bit like a checklist to make sure our product does all the things that we want it to do.

Okay, there are three sections to this lesson.

The first one is all about greetings cards, so let's get started.

So these pictures all show different reasons you may send a greetings card.

Let's have a look at these.

A wedding, a birthday, or Christmas.

Now what I want you to do is have a think on what events do you celebrate where you could send a greetings card to somebody with a special message.

Pause the video, have a think, or have a chat with the person next to you.

Did you think of any? I thought of one.

What about a special celebration at the end of your school year where you could send a thank you card to your teacher? I love it when I get those.

Quick check for understanding.

Which of the following cards would be the best to send to a friend on their birthday? So A, we have a nice picture of a flower.

B, we have a card with a picture of a cake on top.

And C, we have a card with a picture of a Christmas tree and some presents.

Pause the video, have a go, come back to me when you've answered it.

Well, of course this was quite an easy one to start with.

It is of course B because it's got a nice birthday cake on there, it's got "happy birthday," all the candles are lit.

I would love that to be sent to me on my birthday.

When choosing a greetings card, it's important to remember who the card is for.

Can you remember what we called this? Brilliant, yes, the person who you will design and make your card for is known as the user.

So these children have chosen users for their cards.

Let's have a look.

So let's see what Sofia says.

Sofia says, "I need a card for my little sister's birthday.

She's going to be three years old." So we've got some really important information about Sofia's user there.

That is her sister, it's her birthday, and she's going to be three.

That's really useful information if we're gonna design a greetings card for her.

Let's see what Lucas says.

He says, "I want a card for my friend who is 10 years old and is poorly in hospital." Oh dear, Lucas, that's very sad to hear.

But again, we've got some really important information about Lucas' user there.

We know that he's a friend of Lucas', we know he's 10 years old, and we also know, very unfortunately, that he's not very well and he's in hospital.

Quick check for understanding.

The person who you are designing and making your card for is called.

Hmm, is it the designer? That's A.

Is it B, the user? Or is it C, the builder? Pause the video, have a think, and come back to me when you have an answer.

Okay, if you answered B, the user, you got it right, well done.

So we're now onto your first task, Task A.

Now, as we've just found out, Lucas wants to design a "Get well soon" greetings card for his friend because his friend is very unfortunately poorly and is in the hospital.

So what I would like you to do is help Lucas, suggest some ideas that he might use for his card.

Now I've given you a suggested starting point so you can say, "I could use," and then what I want you to do is finish that.

What could you use or what could Lucas use in his card which would be perfect for his user? You could even draw a picture of it, a quick sketch of it, to show what you mean.

Pause the video, have a go at this, come back to me when you've done this task and we'll do a bit of feedback.

Amazing, how did you get on? Well, what I said was, or what Lucas said was, "I could use a card which has someone who is unwell on the front cover." And you can see what we've done there is we've drawn, I've drawn a quick sketch of someone blowing their nose and they look a little bit warm as well.

That would be a brilliant "Get well soon" card to send to Lucas' friend.

How is yours? I bet yours is brilliant and probably better than mine.

Okay, onto the next section of this lesson, disassembled cards.

Some greetings cards are interactive.

Now what do we mean by that? Well, of course that means that the cards might move, make a sound or even light up.

Some nice examples here of a card where you open it and the flower lights up, or maybe a card where the dinosaur makes a roar sound when you move its tail.

Can you think of any cards that you have ever had that were interactive? So remember that means the card moves, makes a sound or lights up.

Pause the video, have a think or have a chat with the person next to you, and come back to me when you've done that.

Did you think of anything? Brilliant.

I thought of one.

I once got a birthday card that when I opened it, it sang "Happy Birthday" to me, brilliant.

Quick check.

What makes a card interactive? Is it A, a card that moves? Is it B, a card that doesn't move? Is it C, a card that is colourful? Or is it D, a card that isn't colourful? Pause the video, have a think, come back to me when you've got an answer.

Right, let's see how you got on.

Did you say a card that moves? Well done if you did.

Some cards might use a slider mechanism or a lever mechanism to make parts of the card move.

So for example, here we have two of these examples.

This is our blue whale and we have the lever mechanism which you can see of course moving backwards and forwards, and we also have the slider mechanism moving from left to right.

So let's disassemble these mechanisms. Now, if we disassemble the lever mechanisms, these are the three main parts of our mechanism.

We have of course the lever, very important.

We have the cover.

And of course we have the pivot points and the split pins.

Now you could say we also have the whale that goes on the top, but of course what we're looking at here is we're looking at the bits that make it all move.

Now let's look at the slider mechanism.

So if we disassemble, remember, that's take apart, the slider mechanism, these are the three main parts.

We have the slot, which we'll have to cut in the front of the card.

We have the slider.

And of course we have the guide.

Remember, that guide is there to make sure the slider stays in place and moves where we want it.

Quick check for understanding, true or false? Disassembling moving greeting cards, greetings cards, helps us to understand how they work.

Is that true or is that false? Pause the video, have a think, come back to me when you've got an answer.

So is it true or false? It is, of course, true.

And why is that? Well, by disassembling cards, we can look at the main parts of the mechanism and the best way to add a moving part to the greetings card.

Right, we're now onto our next task.

So what I want you to do now is disassemble the card pictured here, and there's a little animation to help you even more.

And I want you to answer some questions for me.

Which parts of this card move? Which mechanism does it use? What mechanism can you see being used in that card? And then finally, how does it work? So if I was to get that card through the post and I opened it, how would I have to make it work, what would I have to do? Pause the video, have a go at that.

Once you've done it, come back and we'll look at some feedback.

Okay, how did you get on? Well, this is what I did.

So I said that this card uses a lever mechanism.

Can you see the lever mechanism there? Of course you can.

The box opens as the lever is moved and inside there is the little head of a teddy.

Isn't that brilliant? The lever moves up and down in a curved movement.

So what I mean by that of course is as the lever moves, remember, a lever is a rigid bar, we have the pivot point, as I move that, obviously it makes a curve in the air or on top of the card, okay? I then also, to make things really clear, is I've labelled the pivot and the lever, so you can see that there.

So what I've done is I've disassembled that card and it's given me some really good ideas.

Did you get some ideas from disassembling it? Brilliant, well done.

Okay, onto the final part of this lesson, design specification for a moving greetings card.

Disassembling existing greeting cards helps designers understand the mechanisms in a product and what is already available out there.

Designers also need to understand the user.

We've already talked about that, remember? And that user is gonna be who we are designing and making the greetings card for.

This information is used to help create what we call a design specification.

A design specification describes what a product has to do.

Do you remember talking about that when we did our keywords? Excellent.

Yeah, it's like a list, a checklist of everything that the product needs to be able to do.

Let's check our understanding and our pronunciation of the term design specification.

So, my turn.

Information collected to understand what a product has to do is called a design specification.

Now your turn.

I'll read the first bit with you.

Information collected to understand what a product has to do is called a.

That's brilliant pronunciation, well done.

With the greetings card design specification, we need to consider a few things.

We need to consider who the product is for, the user.

What sort of greetings card it will be, we've already looked at lots of different examples of that.

How it will move, so which one of those mechanisms we're going to use in our design.

Let's do a quick check.

What does a design specification do? Is it A, lists ideas for the product; B, describes a product to others; or C, describes what a product has to do? Pause the video, have a think, and come back to me when you have an answer.

Well done, did you answer C? I bet you did.

It is of course describes what a product has to do.

Okay, we're now onto the final task, Task C.

What I would like you to do is create a design specification for making your card.

Now let's think again about the things you need to consider.

I would like you to answer these questions.

First of all, who is your card for, who is the user? What type of greetings are you gonna use in your card? So is it gonna be birthday, get well soon, or have you thought of your own? Hopefully you have.

What movement will your card make? And linked to that, will your card use a slider or a lever mechanisms to be able to do that movement? So you're gonna have to think about this very carefully, I want you to be creative, and you also might want to chat to the person next to you.

Pause the video, answer those questions, come back to me when you've done that and we'll go through some feedback.

How did you get on? I'm sure you've thought of something far more creative than I have, but let's look at what I put down as an example of an answer.

So your design specification, it might look a little bit like this.

So, who is my card for? It is for my parents.

What type of greetings is it? It's to celebrate a wedding, so this might be a wedding invite.

What movement will your card make? I want it to go up and down in a straight line, and I've already started to think about the things that I might be putting on there.

Will it use a slider or a lever? Well, for this, because it's going up and down in a straight line, I am of course going to use a slider mechanism.

What did you decide? We've now come to the end of the lesson.

Well done today, you've been absolutely brilliant, and you now have a design specification for your greetings card.

You've thought really hard about your user and you've also decided on the lever mechanism that you're gonna be using within your card.

Let's just have a quick overview of what we've done today.

So, some greeting cards have levers and sliders in them to create movement.

Disassembling greetings cards with moving parts develops knowledge of how they are constructed.

A design specification describes what a product has to do.

Identifying users of greetings cards helps create the design specification.

Identifying how levers and sliders work in greetings cards helps create the design specification.

Well done today.

I look forward to seeing you in a future Design and Technology lesson, bye-bye.
