Hello my name is Mrs. Bishop and it's wonderful to see you again, I hope you have been enjoying our lessons in this unit called Keep it safe: shell, solid and combination structures.

I'm looking forward to getting started today.

In today's lesson we will explore the context and purposes of structures.

We're going to also develop our sketches and see how they will influence our final design for our structure.

In this lesson you will need an exercise book or some paper and also a pencil.

Today you should have begun by completing your intro quiz.

Well done! Next we will look at the context of structures.

After that we will look at the purposes of structures.

Then we shall look at developing our structures.

Then finally today I would like you to complete your exit quiz.

Now we have some keywords today I will say the word and I would like you to repeat the words after me.

I will also read a definition of each of the phrases.

Structure, say the word structure.

This is an object constructed in several parts.

Context, say the word context.

This is the circumstances in which a product will be used.

Next word is purpose, say the word purpose.

This is the reason why an item is created.

Next word is developing, say the word developing.

This is to become more advanced and elaborate.

Let's begin by looking at the context of structures.

Now there are many types of structures.

Think back to everything that we have learned before, you've learned lots about different types of structures and we find out that there were three main types of structures.

Let's remember those together now.

The first one was shell structures these were structures with a thin outer coating.

They help to keep it strong and protect something.

There was also solid structures these structures are a solid mass the whole way through.

And there was also combination structures which are a mixture of different types of structures such as shell, solid and also frame structures.

Now I wonder if you can match these structures to the different types.

So we got shell, solid and combination.

And we got over on this side three different pictures of three different types of structures.

I want you to pull from what you already know and match the different structures to the different pictures.

Welcome back let's go through the answers together.

Now the first one we're going to look at is shell structures which one was the shell structure? That's right it was the bicycling helmet.

The next one we're going to think about is which one of these pictures is a solid structure? That's right it was the building blocks cause they're solid the whole way through.

And finally the combination structure must be the house and that's correct because a house is made from a variety of different types of structures.

Now there are also lots of different examples of structures Here are some examples of shell structures for example we could have pencil cases, packaging boxes, bottles, igloos and a lunchbox.

Solid structures could be things like dog's shelters, a wooden chair, picture frames, or doll's houses.

I might also have some combination structures such as tents, houses, sofas, and umbrellas.

I wonder what type of structure you are planning to design and make or you can choose your own thing that you're interested in that's the best one to make.

Now structures have context and what is their context? Each type of structure has a context.

And this means the circumstances in which it will be used.

So I wonder if you can now help me match the context to each structure so I've got some different structures here I've got egg cartons and gift boxes, chocolate boxes, and toy chests, and in the middle I've got two different contexts I've got celebrations and in the home.

So all I want you to do is pause the video now and see if you can match each of my structures to the different contexts.

Welcome back! Let's see if we can go through the answers together.

Egg carton would that be for a celebration or in the home? That's right it's in the home.

Gift box would that be used for celebrations or in the home? That's right it's used for a celebration.

Chocolate box what do we think celebration or in the home? That's right it's mostly used for a celebration.

And a toy chest used for a celebration or in the home? That's right it would be used in the home.

So these are context for some different structures.

I wonder if you remember what your structure is that you were designing what's it's context? Can you remember? Now what I want you to do is think of many more context can you think of any, any other context where we might use our structure? Pause the video now and have a think.

Welcome back! Well what did you think of? Do you want to read them out to me now? Oh! Wonderful you're all doing so well in this lesson.

Let's see I've got some on the screen I can share with you.

I got school.

Did you get school? Outdoors that's a brilliant one, did you say that one? Shops there's another context.

Gyms there's a great one did you get that one too? Or have you got some different ones? Did you get restaurants? Perhaps parks or cinemas or maybe more that you thought of yourself.

There's many different contexts with many different types of structures and depending on the structure we're creating and designing will depend on the different contexts as well that we could use it in.

How will your product that you design work in a context? When you're designing, making, evaluating structures you need to think about how the structure will work in the context and which context your structure may be used in.

Cause this might actually influence and determine the materials you used for your structure, the shape, size, and style of the structure and also the equipment that you might use to make the structure.

It's very important that you're keeping in mind what you want to design, make and evaluate.

I'm making sure that it will work within that context that it could be in.

I want you to now to pause the video to complete your task.

I want you to make a list of the context your structures will be used in.

Think about each context will influence the materials used and the shape, size and style of your structure.

You may pause the video now to complete your task.

Welcome back! We're now going to look at the purposes of structures.

Can you remember writing your design brief? Can you remember what your design brief said? It might have said something like this I will design, make and evaluate a particular type of structure for a particular type of user to meet a particular purpose.

Maybe you used some of these ideas maybe you thought some of those structures: a tent, a pencil case, a desk organiser, a lunchbox or a packaging box, a pet's shelter, a cycling helmet or a toy.

And maybe you thought about possible users, the users could be yourself, a parent or carer, a sibling, a relative, a friend, a neighbour or even a guest to your home.

And the possible purposes could have been for a celebration, storage, packaging or protecting a product, presenting it in a nice way or for even for postage.

I want you to pause the video now and remind yourself what your design brief was.

Welcome back.

Can you read out your design brief to me now? Thank you! Now every structure has a purpose.

This means the reason why a structured is created.

Can you think of some purposes? Can you pause the video now and have a think.

Welcome back can you read me out the purposes you thought of? Oh how wonderful you're all very smart today.

Maybe you said to protect a product during transportation.

Perhaps you said to present a product that is a gift.

Perhaps you said to contain a product keeping it safe and intact.

When designing, making, and evaluating structures we really need to think about the purpose of our structure at all times.

Cause this will influence and determine the materials that we'll use for our structures, the shape, size and style of the structure.

And also the equipment used to make the structure.

Now I want you to pause the video to complete your next task.

I want you to write about the purpose of your structure think about your structure very carefully.

What is it's purpose? Write down the materials, shape, size and style of your structure.

Why is this the best choice for the purpose of your structure? Pause the video now to complete that task.

Welcome back I hope that you have now written down the purpose of your structure.

Well done everybody.

The next thing we are going to do is we are going to start to develop our structure now.

Now we will develop the sketches of our structure more.

By thinking carefully about the contexts and purposes of your structure, we will develop our sketches we did last time to become more advanced and elaborate.

So today I want to think about how I can develop the sketches that I have done before.

So here are my sketches that I've done before for my structure and I've chosen to do a dog's shelter of course you might have chosen to do something different than me.

So that's why it's very important to keep on referring to your design brief which I have over here to make sure that you are designing and making what you want to do.

Just remember today that we are going to develop some of our ideas that we had before and by developing them we are making them more advanced and elaborate.

We're going to spend more time today just focusing on one design that we would like to make eventually.

So all we need to do is take a fresh sheet of paper today and we're going to look at how we can develop this design to make it more advanced and elaborate.

So I think I am going to focus more so on the traditional dog kennel shape cause I quite like that and I think that my dog would quite like that too.

So I am going to spend my time today thinking about how I am going to make sure that I am thinking about those contexts and purposes of my structure making sure that my design meets those points.

So I need to think about what my structure needs to do and I think that my structure's going to be made from wood and I need to make sure that I can make that wood waterproof so that the dog can stay safe and dry inside.

But I also need to make sure that the structure is just the right size for the dog.

So it might be quite important that I measure my dog at some point to see what size I actually need to make it.

It's the same for a plan if I was making a bridge or a cycling helmet or any other type of structure.

I need to make sure that it's going to be fit for purpose for the user.

So what I am going to do now is start using sketching techniques to sketch my design in more detail.

Thinking about all of the things I've just talked about.

So I'm going to make my design in a similar shape but I might change some stuff as I am going along.

And one of the nicest things to do in your sketching is to just take your time and use little lines like this until you begin to buildup the shape.

And don't worry too much about messing up or if you make a mistake because we call these construction lines.

We can always rub out anything that we don't like.

So I want to just gently sketch our design onto to the paper, try not to lean too hard because if you do want to rub it out then it would be nice to be able to do that.

.

at the end if the lines aren't too darkly sketched.

At some point you might want to use a ruler to measure what you're doing and also a bit to get your lines nice and straight.

So I'm setting this is going to be twelve centimetres and I'm measuring as accurately as I can.

And then I'm measuring these two sides the same length so I can make them the same length by measuring.

Let's just measure eight centimetres.

And again on this side eight centimetres and this is going to help my dog's house to be accurate and correct.

And then I want to think about the roof.

Well this is twelve centimetres perhaps I'll go to the midpoint and I can add a what I call a construction line.

So a light line like this that's going to help me join up the roof to the top.

And that's going to make those sides symmetrical.

And this line is a construction line so it can also be rubbed out whenever I no longer require it.

There we go.

Lets go on now.

I want to think about how this structure is going to be designed at the bottom I'm going to have a box, a 3-D box, a cuboid.

And then on these sides are going cuboids too.

To make them nice and strong.

Remember a probable created a model of this structure rather than a final structure made from wood and my model will most likely be made from cardboard so I am thinking about those techniques that I have learned before that have helped me.

I am thinking about how I could use some corrugated cardboard for the roof.

Make it really strong.

Then I might also coat my roof in a plastic coating so that it will be waterproof for the doggie.

I want to add in all those details.

Also I don't want the front to be completely open because I want to keep the heat inside of my structure and I want you to think about that as you are designing your structure as if you're designing a cycling helmet or a tent.

How would you have to make sure that it's going to be fit for that purpose and fit for that user so I am thinking about that all the time as I am going, as I am designing.

I want to include that little heart shape.

I think that looks quite cute.

And on the front maybe I'll decide to use some fabric to keep the dog nice and warm.

So I might think about how I could design that.

That we have the fabric coming down like this on the sides.

Okay.

I can also shade in my design if I want using coloured pencils or just using the pencil that I have just to add some shade.

So I can sit and shade them as well.

Now I hope that you're going to enjoy developing your own structures today.

I am sure you are going to make them absolutely wonderful.

I want you to pause the video now to complete your task.

I want you to think carefully about the context and purposes of your structure.

I want you to develop the previous sketches you did so they are more advanced and elaborate.

Pause the video now to complete your task.

Now I want to say thank you for joining me today.

I hope that you've enjoyed learning more about the context and purposes of our structures.

I think you've done really well and I'm really looking forward to seeing your sketches.

So if you don't mind holding them up for me now.

Look at those Furby aren't they wonderful? He really loves all your sketches.

I really hope you're enjoying learning about structures and also starting to create and develop your own ones.

Hopefully I will see you again soon.

We can continue to keep on going with our lessons.

Goodbye for now.
