Hello, my name's Mrs. Fletcher, and I welcome you to today's design and technology lesson.

Today's lesson is called assemble packaging, and it's part of the shell structures packaging unit.

In this lesson, we'll be looking at the different techniques that are used to help build and construct packaging once the design process is over.

So let's have a look at what we'll be learning about today.

The outcome of today's lesson is I can join card with accuracy.

So we are going to be looking at the skills we need to take a piece of material and turn it into the packaging that we have designed.

There are some key words and phrases that we'll need in today's lesson.

We're going to see these quite often, so let's have a look at those together before we get started.

So first of all, we've got the word prototype.

Can you repeat that? Prototype.

Well done.

And a prototype is like a model version of a product that we can use to test things, so, and to check measurements and things like that.

Then we've got the word dimensions.

Can you repeat that? Dimensions.

Well done.

And the dimensions mean the size of each part of a product.

So it's the measurements, the sizes of each thing.

Then we've got the word assemble.

That's key in today's lesson.

Can you repeat that? Assemble.

Well done.

And that means to put separate parts together.

So bringing together different parts, assembling them means to bring them together.

And then finally, we've got the word join.

Can you repeat that? Join.

Well done.

And join means to attach two or more things together.

Okay, so today's lesson is going to be broken down into two parts.

First of all, we're going to be looking at developing packaging.

So that's looking closely at those dimensions and parts that we will need in order to make the packaging.

And then we're going to be looking at the assembly of the packaging, putting it together.

So let's get started with developing packaging.

The Oak Biscuit Company has had a problem with their biscuit packaging, and they need you to help them to redesign it.

So here we've got an image of their existing packaging, a plastic wrapper.

They need packaging that will protect the biscuits from breakage, that will allow the packs of biscuits to be stacked.

So that means they can sit on top of each other when they are on display.

And the packaging needs to be sustainable.

So that means that it uses a material that can be easily replaced and won't cause any damage to the environment.

We also need to make sure that that packaging is easy to recycle for the person at home.

Aisha has chosen this style of packaging for her design.

So she's gone with a triangular prism shape for her packaging.

She's already drawn up a net to show how she would make that shape.

So to draw the net, she looked at the 2D shapes that would help to make that 3D shape.

So the different faces of the 3D shape that she's going to make.

To make sure the biscuits will fit inside the new packaging, we need to work out the dimensions.

Now remember the dimensions are the measurements that tell us the exact size of each part.

So you can see here, we would need to know lots of different dimensions for the packaging.

We'd need to know how long it is, how tall it is, how wide the opening is.

Each face of that packaging, we would need the details of how big to make it.

Luckily the biscuit company have sent us the dimensions of the biscuits that they sell.

So this is the information we've got from the biscuit company.

So these are their strawberry cream biscuits, which they want help with redesigning the packaging.

You can see here that a single biscuit measures 40 millimetres by 40 millimetres.

So that's the size of an individual biscuit.

The pack of biscuits that they sell contains 10 of those biscuits, and when they are lined up in a roll like that, it measures 120 millimetres.

So that's information that we will need in order to make packaging to fit those biscuits inside.

So we can use this information to work out the dimensions of the packaging.

So we start with that measurement of a single biscuit is 40 millimetres wide.

So if we draw around the shape, draw around the biscuit, the shape of the packaging that we are creating.

So in Aisha's case, it's this triangular shape packaging that she's making.

We draw that around the biscuit, and we can start to work out how big it's going to be.

So here I can see, if I take that 40 millimetre measurement and measure along the edge of that triangle, I can see that it's more than 40 millimetres because 40 millimetres would measure about halfway.

If I measure another 40 millimetres there, I can see that's the length of the packaging I will need.

So that edge of that triangle needs to be twice the size of the biscuit in order to fit the biscuit inside.

So that side of the triangle is going to be 80 millimetres.

So we've used the size of the biscuit to help us work out the size of, in this case, the triangular packaging.

So that means because it's a triangle, an equal triangle, an equilateral triangle, that each side of that triangle will be the same, will be 80 millimetres.

So we've got the measurements for the triangular shape.

The three rectangles are what form that triangular shape in Aisha's packaging.

And if we look at it in the net form, it's those three rectangles lined up together there.

Now it's the edge of those rectangles that are going to form that triangle shape.

So that's where that 80 millimetre measurement dimension comes in.

So each edge of the rectangle is going to be 80 millimetres.

So when they're folded together, each side of that triangle is 80 millimetres.

If we think about the 10 biscuits that we need to fit inside, that will help us work out the length of those rectangles that we need to make.

So we've got the depth of them, how thick they need to be, now we need the length of them.

So we know from the dimensions that the biscuit company sent us, that 10 biscuits measures 120 millimetres.

Now we don't want to make the packaging exactly the size of the biscuits because then there's no room for them to move slightly and they may be squashed too tightly inside.

So if we add an extra five millimetres to that measurement, it gives a little bit of extra space to make sure the biscuits fit inside.

So we know then that the length of those rectangles, of the packaging will be 125 millimetres.

So again, the dimensions of the biscuits are helping us work out the dimensions of the packaging.

The triangular sections that make up the sides of Aisha's packaging must match those sizes that we've just worked out for the rectangles because they need to fit and fold with those rectangles.

So if the edge of the rectangle was 80 millimetres, then that means that the edges of the triangle corner pieces or side pieces will also need to be 80 millimetres because they form that equilateral triangle on the side.

The same method that we've just used for Aisha's packaging can be used for other types of packaging, other box shapes as well.

So if we look at this one, this is more of a cuboid shape.

So we are gonna use the same information to work out the dimensions of this type of packaging.

So we think about the biscuit size, which was 40 millimetres.

We draw the shape of the packaging around that biscuit size.

So you can sketch out or draw out the dimensions of the biscuit, draw your packaging shape around it, leaving a little bit of space for room to put the biscuits inside.

And then we need to measure.

So a square shaped packaging can be the same dimensions as the biscuit, but with a little bit added on just to give it some room.

So it'd be 40 millimetres plus an extra five millimetres just to give it some extra room.

So this is a the different dimensions to the triangular packaging because it's a different shape.

So we can see there then if we have the four rectangular pieces of the net of that cuboid shape, each side of those rectangular pieces will each need to be 45 millimetres because they're all the same shape.

We know already from Aisha's packaging that the length of the packaging needs to be the same.

120 millimetres was how much space we needed for the 10 biscuits, but we've added five extra millimetres just to give them a little bit of room to fit in comfortably.

So that means the length is 125 millimetres.

The side sections, just like on Aisha's packaging, need to match the main part of the packaging.

So in this cuboid shape, the side sections are squares instead of triangles.

So if the side of the rectangles was 45 millimetres, then that means the sides of those square pieces also need to be 45 millimetres.

So they will line up and match up with those rectangular pieces once the packaging is folded.

A quick check before we move on then.

Which dimensions would work for this biscuit? So if we had a biscuit that was 70 millimetres across, which width of packaging would we need to use to fit that biscuit inside? Is it a, packaging that's 65 millimetres wide, b, packaging that's 50 millimetres wide, or c, packaging that's 75 millimetres wide? Pause the video and have a think.

Welcome back.

How did you get on? Well done if you said it is c, 75 millimetres.

The size of the packaging needs to be at least the size of the biscuit that's going inside.

So 65 millimetres and 50 millimetres would both be too small.

75 millimetres gives us a little bit of extra space to fit that biscuit inside.

Well done if you worked that out as well.

So let's run through the steps that you'll need in order to make a prototype for your packaging design.

So we're going to make a prototype net.

We're going to use recycled card as well to make this sustainable project as well.

So step number one to make a prototype is to work out the dimensions of your packaging design and add them to your net drawing.

So you're going to use the information that was given to us from the biscuit company about the dimensions of the biscuits to make sure that the biscuits will fit inside your packaging.

So you've already got a net drawing.

Now you're going to add those exact dimensions, those exact measurements that you will work out using the information from the biscuit company.

Once you've done that, you are then able to draw the packaging design net onto a piece of recycled card.

So something like a cereal box is good for this task.

You're going to use a ruler and pencil to make sure that those lines are very accurate and you are going to use the dimensions that you did in step one.

You could, if you wanted to make it easier, cut out each of the pieces from paper first, so measure and cut out using paper each of the faces of your net in order to make sure you've got them all accurately, and then use those as templates to draw it onto the cardboard.

So you could draw around them or you could just use them \to make sure you've got all the pieces that you need before you draw them.

Make sure you add the tabs into the correct places.

So remember the tabs are the pieces of extra material that will be used to join different parts of the packaging to each other.

So you need to work out where they will go as well when you do this step.

And then you can cut out the whole net including the tabs, so you're left with something like this.

So this is the flat 2D net of the packaging that you are going to, that you have already designed.

A quick check before we move on to the task then.

What is a prototype? Is it a model, a drawing, or a finished product? Pause the video and have a think.

Welcome back.

What did you think? Well done if you said it is a model.

So exactly, a prototype is a model of something that you have designed and is going to be made.

Well done if you got that right.

So for your task, then you're going to use those steps to make a prototype net of your packaging prototype.

First of all, you work out the dimensions, then you draw the net shapes onto card using templates if needed.

Then you add the tabs in the correct places, and then you cut out the whole net shape.

So you're left with the final image there, your whole net cut out including the tabs.

Pause the video while you complete this task and come back when you're done.

Welcome back.

How did you get on? Well, Aisha has been following those same steps to make the prototype for her packaging net as well.

So she's saying there that she used the measurements from her net drawing in stage one to make the card prototype.

So there, she worked out all the dimensions using the information from the biscuit company about the dimensions of the biscuit, and then she drew it onto the card and cut out including those tabs as well.

So she's got a net now of her triangular prism packaging that she designed earlier on.

Well done if you manage to get your net cut out and complete just like Aisha.

So it's time for the second part of the lesson now.

In this part of the lesson, we're going to be assembling the packaging.

So we're going to be taking that 2D net and turning it into a 3D packaging product.

A net can be assembled to form a 3D model.

So that word assemble means to put together.

So we can put the net together to make the 3D model.

So we start with the flat net, and it becomes shaped into the 3D model.

And then it needs to be joined in order to keep that shape, to stay in that shape.

There are different techniques that we can use to do this.

A quick check then before we move on to looking at those techniques, what does that word assemble mean? Is it to measure lines accurately? Is it to cut out a shape, or is it to put parts together? Pause the video and have a think.

Welcome back.

What did you think? Well done if you said to put parts together.

So to assemble something is to put it together.

Okay, so let's have a look at the steps that we need to take to assemble a packaging prototype.

So we'll start with step one, which is about shaping the card.

So you're going to use a ruler to bend the card along the lines that you have drawn.

So taking your net cardboard shape that you've made your flat shape, and you're going to use a ruler, using the bending technique with a ruler to bend along those lines that you have drawn.

This will be where the card is going to fold.

So it's where you're going to fold the card in to make the 3D shape.

Make sure you bend each piece in the same direction.

So they're all going to fold up together.

We need to bend each piece in that direction.

So it's going to fold into the right shape.

You might need to use a scoring technique using scissors to press the line into the card if you are using a thicker card such as a corrugated card.

That will make it much easier to bend when you're putting the shape together.

So let's move on to the next steps, which are about joining those pieces together so they stay in shape.

So once you've bent or folded or scored those lines into your card, you're going to fold the net into shape.

So you're going to fold along all those lines that you've just bent or scored in order to bring the 3D shape together.

And then you're going to decide whether to use glue or tape to join those tabs in the correct places.

You need to leave one end of your packaging unjoined, which is the opposite of join, so it's not fastened, in order to allow access to be able to get into the packaging.

So we can put the biscuits in or the biscuits can be taken out.

Now when you're thinking about whether to use tape or glue, consider that if you use glue and you apply it nice and accurately, then it will be hidden.

You won't be able to see how your packaging is joined.

But if you use tape which will be applied on the outside of your packaging, then you will be able to see that.

So we do want our prototype to be accurate, and neat, and finished even though it's not our final packaging piece because this is a good place to practise those skills of joining and making sure that it looks how we want it to look as well.

So consider which method you use for that.

Quick check then before do move on, which joining method would be hidden if we did it accurately? Would it be glueing , taping, or stapling? Which one would be hidden? Pause the video and have a think.

Welcome back.

What did you think? Well done if you said it's glueing.

So if you apply glue accurately, then it will be hidden inside those folds on the tabs, and we won't see it on the outside, which makes for a nicer finish to your product.

Well done if you got that right.

Now the prototype has been assembled, and it's staying in its 3D shape, we can check that the dimensions will work.

So that means we can check that the biscuit will fit inside or the biscuits will fit inside.

So we know from the biscuit company that the each biscuit measured 40 millimetres across and 40 millimetres high.

So it's a perfect circle.

So we can cut that out of a piece of thick card like corrugated card and make a representation of the biscuit, a pretend biscuit, and we can use that to see if it fits in the opening of your packaging.

And that will tell us whether we've got those dimensions correct or whether we have measured accurately to make that packaging.

Time for your task then in the second part of the lesson.

So you're going to use the steps for shaping card to bend the fold into your net to turn that flat card net into a 3D shape.

So you can either use the bending technique or the scoring technique if you are using a thicker card.

Once you've done that, you're going to use the steps for joining card to hold that assembled net in place.

And you're going to decide which of those joining methods, glueing or taping that you're going to use to have the best finish for your prototype.

If you use glue, remember it can be tricky to apply accurately.

You need to make sure you neat and tidy when you're applying it, and it needs time to dry.

So it won't immediately hold your net into its 3D shape.

You might need to hold it or secure it in some way while it dries before it will stay in shape.

If you use tape, that doesn't need any time to drive, it will be ready to use straight away, but it can be seen on the outside of your prototype so it can affect the finish of your prototype.

So choose carefully which one you're going to use.

Pause the video while you complete that task and come back when you're done.

Welcome back.

How did you get on? Well, now that you've assembled your packaging and you have your 3D shape, it's time to test it.

So in order to test it, you're going to cut a 40 millimetre circle from the very thick card in order to represent a biscuit, and you're going to check that it fits inside and that will tell you whether dimensions of your packaging are correct, whether you've measured those dimensions accurately to make that net, to make that packaging.

Pause the video while you make your biscuit and test your packaging.

Come back when you're done.

Welcome back.

How did you get on? Hopefully, your packaging design worked and the dimensions were just right to make sure that the biscuits fit inside.

Aisha has been following those steps as well.

She has been shaping, joining, and checking that her packaging is correct.

She tells us here that she chose to use glue to join her prototype because it can't be seen on the outside.

She did, however, have to take her time to apply it very carefully and then hold it in place while it dries.

So she knew it would be tricky, but she's chosen that method because it would look nicer from the outside.

So well done to Aisha and well done to you if you managed to complete your prototype packaging as well.

It is the end of the lesson now, and we have had fun assembling our biscuit packaging and checking it using our pretend biscuits.

We have learned that a prototype is made to test whether a design will work and to check the dimensions and the scale.

So the sizes that we have used to create our prototype.

Prototypes can be made from recycled materials.

So it's a good idea to make those prototype models using materials that won't waste resources and can be recycled or used again.

Using a ruler to fold along those fold lines creates an accurate bend, which helps to assemble our packaging easily.

And design decisions can be made about the way that we join our packaging together as well when we're assembling those nets.

And it comes down to whether we want the joining method to be visible or not, and we need to make sure that we apply them carefully to make sure they look as good as they can.

Thank you for joining me for this assembling packaging lesson.

I hope to see you again in the future, but it's goodbye for me for now, goodbye.
