Hello, my name is Mrs Bishop and I'm so happy to be here to teach you design and technology today.

This unit is called, Keep it safe, shell, solid and combination structures.

Ooh, I can't wait to begin.

I hope you're in a nice quiet place so that we can start.

In today's lesson, We will Analyse and evaluate existing structures.

This is a really important step before we begin to design our own structure.

As we need to gather ideas and informations from those existing structures.

In this lesson you should have began with your intro quiz which you should have already completed so well done.

Next, we will look at the existing products.

After that we're going to look at user suitability.

Next we should look at the design features that we can find in existing products.

Next we shall look at what we like and dislike about the existing products.

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

Okay, now we shall look at some keywords.

I will say the word and I would like you to repeat it after me.

The first word is product analysis, can you say that word? That means to look closely and carefully at an existing object to find out more about it.

Our next word is function, can you say that word? That means what a product does.

Our next word is shell structures, can you say those words? These are hollow structures with a thin strong outer coating.

Our next word is solid structures, can you say that? Solid structures are solid material the whole way through.

And we also have combination structures, can you say those words? These are a mixture of shell, solid and frame structures.

Now we are going to begin by looking at some existing products.

Let's look at some together.

Here are some that I have found.

The first one is a dog shelter, and this is an example of a solid structure there it is.

Can you see that the dog shelter is made from wood that's strong and sturdy and helps to keep the little dog safe inside? Next one I found was a tent and this is an example of a combination structure.

Because we do have a shell structure with the fabric the tents made from, but also we do need some strong poles and they're made from a solid structure.

And can you see there is our tent? And that's lovely because it's going to keep us nice and dry when we're out camping outdoors.

And the next one I found was the pencil case.

And my pencil case is made from fabric which is soft to the touch, but also does a really good job keeping all my pencils and pens and my ruler safe inside.

Now, what I want you to do, is to pause the video to complete this task.

With an adult supervision, I want you to go around and look at some of the products that you can find in your home that are made from shell, solid, or combination structures.

Find around three, that you would like to look at more closely today and bring them back to me.

Pause the video now to do that task.

Oh, welcome back, I wonder what you found.

I wonder if you could have a look at your structures now and see what you think, what sort of structure they might be made from.

Maybe you found some of these products.

Perhaps you found a tent, perhaps you found a pencil case, perhaps you found a desk organiser, maybe you found a lunchbox.

Perhaps you found some packaging boxes or a pet shelter.

Perhaps you found a cycling helmet or perhaps you found some lovely toys.

But all of these products are actually shell, solid or combination structures.

I wonder what products you brought back and what sort of structures they are.

Maybe you could hold them up to me now and tell me what sort of structures they are, so hold up your first one.

What is it? Hold up your second one, what is that one? And hold up your third one what type of structure is that one? Oh, thank you, well, that's very interesting, isn't it? Okay, I've just disappeared for a moment but I am still here.

The reason why is because I want you to draw a table now.

Can you see this table on the screen? We are going to conduct our own analysis and evaluation of those three products that we found.

To do this, we do need to draw a table like this one.

During this lesson we are going to be filling out this table together.

So what I would like you to do is I want you to draw the table with these headings, can you see them? I've got product, function, user suitability, design features, and likes and dislikes.

And you can see the in my table I have three rows.

I've labelled them 1, 2 and 3.

I'd like you to pause the video now and draw this table.

Welcome back, the next thing I want you to do is very carefully and very accurately, I would like you to draw each of your products into the product column.

So I found my dog's house, my tent, and my pencil case.

And can you see that I have drawn them neatly into the product column.

Can you pause the video now to give this a go? Welcome back, I hope that you've drawn your three products I am so interested.

And then, the next thing that we want to do then is we want to complete our function column.

Now, the function of our product is what it does.

So if you look at my first product the dog's house, this is a dogs outdoor shelter it keeps the dog warm and dry.

So that's the function of my first product.

Then I filled in the next function for the tent.

And I said, this is a tent.

It provides a place for people to shelter outdoors.

And my third product was the pencil case.

And I've written down, this is a pencil case.

It holds pencils and pens securely inside of it.

So I want, you now to pause the video and complete your function column.

Welcome back, I hope now you've written down the functions of your three products.

Now we're going to look at user suitability.

So, what is user suitability? This is thinking about how the products are suitable for the intended user.

So let's look at my first example.

My first example was the dog shelter, and my intended user's of course they're? The dog that's right.

And is it suitable for the dog? Well, I think it might be, it's the right shape and size for the dog and it helps the dog stay dry and warm.

My next product was my tent.

How is this structure suitable for the intended user? Who would be me, I wanted to go camping.

Well you can see that it's lightweight, so easy to carry.

I can see that it is waterproof.

So it's going to keep me nice and dry when I'm outdoors.

And my other product was my pencil case.

How is it suitable for the intended user? Well many different people use pencil cases, but as I can see, it's stores that holds pencils inside of it keeping them nice and safe.

Now in a moment I am going to disappear again but I'm still here.

Now, as you can see, I have disappeared, it's because I want to show you the table again.

Now on my table, I have no filled in the user suitability column.

I'm just going to go through it with you before I'm going to ask you to do the same.

So for my first product, the dog's shelter, I have written that this is made from wood which is solid and strong to keep the dog safe.

For my second structure the tent, I have written the tent is made from waterproof material, keeping people dry inside of it.

And number three, my pencil case, I have written that the zip on the pencil case keeps all the pencils safe inside.

And this is what I want you to do now, I would like you to fill in the user suitability column for your three products that you have found.

Now look at them very carefully and think, who are the users of these products? How suitable are the products for each of the users? Pause the video now to complete your task.

Welcome back, well, I hope you were able to fill in that column.

Let's move on to the next thing now.

The next thing we want to look at is the design features of each of our products.

So let me have a look at my three products that I found again.

And I want to think about for each product what design features they have.

So let me look, so with my dog shelter what do I think about the colour of the dog shelter? Well, I quite like it.

What do I think about the shape and the size of the dog shelter? Well, I can see that it's just the right size for the little dog to fit in.

I think the ship is really well designed especially with that triangular roof which is going to stop the water from getting onto the dog and it's going to really go away quite quickly.

Next thing I could look at is my tent and looking very carefully at my own tent that I've got in front of me, what do I think is really important about it? Well, I can see that it's a cool, blue colour which kind of suits that outdoors kind of look.

I can see that that material is very lightweight which I think is quite important because when I'm going camping, I don't want to have to carry around anything That's too heavy, especially with all the other things that I'm going to have with me.

So that's an important design feature.

And also that it folds up into a very small shape so that's easy to transport.

And my other one was my pencil case.

When I look at the pencil case, I can look at the graphics used on it, we see the little picture of the cat on the front, and I could see the purple colour.

And both of those design features are very appealing to me because there are two of the things that I like.

And of course everyone is different so some designs will be nice to us and some won't.

Now I'm going to disappear in a moment.

Here's our table again.

And can you see now that I have filled in my design features column and I want you to start thinking about this column now.

So why don't you just start to think about what design features do you like your three products and look at how I've done mine.

For the dog shelter I've written now about the shape.

And I've said the shape of the dog shelter works well, at just the right shape and size for the dog to sit comfortably.

Next I wrote about my tent and I've written that the tent is a cool blue colour that suits the outdoors and it's made from a thin fabric making it lightweight yet still waterproof.

And finally my pencil case.

And I said that for me it has an appealing design and a unique logo, it is soft and very easy to use.

Now, I want you to complete that column thinking about the colours and the logos and fonts used on the three products that you can see.

How does your product appeal to the user? Maybe what stands out or blends in? Pause the video now to complete the design features column.

I'm back again, I hope that you've now completed your design features column of your table.

We're moving on now to our likes and dislikes.

So let's have a look then at my three products again.

What do I dislike or like about each product? We're looking at the dog shelter first.

I like the shape and size of it, but I dislike that colour.

I think maybe the dog size could be a better colour.

And perhaps looking at the tent there and what do I like about the tent? Well, I like that it is a good size for two people.

I like that it is waterproof and I like that it is lightweight.

But perhaps what I would like to see changed about it is maybe to include a window so I can see out to beautiful nature outside.

I know that's what I want to see if I was to go camping.

And finally my pencil case what do I like it about it? I like that it keeps all my pencils safe and secure.

What I dislike about it is, that sometimes I have to poke around lots to try and find all the different pencils, it'd be easier if they each have their own compartment or special place.

And that brings me on to my next part of my table now.

So I'm going to disappear again.

So, here I am again, looking at my table.

And I want to complete the likes and dislikes column.

And as you can see, I've completed it from my three products.

My dog's house I've said that I like the shape of the product, but I dislike the colour of the product.

For my tent, I said that I liked the waterproof material of the product, however, I dislike the warmth provided, which I suppose could be true.

And for my pencil case, I said, I like the fabric of the product, however, I dislike the size of the product.

Now what I want you to do children is I want you now, to complete this part of your table thinking about maybe one thing that you like, and one thing that you dislike.

Perhaps you can actually think of some more things.

I think about the materials, the size and shape, and also just how well this product meets the needs of the user.

So pause the video now and give that a go.

Welcome back, oh, I hope that you've been able to think of some dislikes and likes for each of your products.

Hello, I'm back again.

I hope you've enjoyed evaluating existing products with me today.

Now that we know what's important about other products hopefully we're starting to gather some ideas for our own shell, solid or combination structures.

I know today, that looking at the dog shelter was really important for me because I'd like to introduce you to my little friend.

This is Freddie, and I think my product might be designing a little dog shelter for him.

Of course your product might be something different, because structures are used everywhere.

And you have to choose something that you're going to be interested in designing.

Well, looking forward to see you next time.

Someone's a little bit tired I think, bye.
