Hello, my name is Mrs. Bishop, and I will be your design and technology teacher today.

How are you today? That's great to hear.

Welcome back to this unit called, Keep it safe: shell, solid and combination structures.

We're now on lesson 9 of 10, and in today's lesson, we'll be assembling, joining, and combining materials to create our final project.

So, I hope that you are sitting comfortably and you're ready to begin.

In today's lesson, you will need a pencil to draw and sketch with, a ruler to measure accurately with, card you can use, any card that you have at home, including recycled cardboard.

You will also need scissors, and these must be used under the supervision of a parent or a carer.

You may need tape, such as sticky tape or masking tape.

In today's lesson, you may also need some colouring pencils to use to finish our structures, some glue to stick things together or add on extra features to our structures, and maybe you might need some paint, again, to use to finish our structures.

You perhaps might need other materials.

It will really depend on the structure that you are making.

So, if you need to gather anything, go and do that now, so that you're ready to begin our lesson.

Today you should have started with your intro quiz.

I've put a big tick beside it.

Well done if you've done that.

Now we are going to look at assembling and joining.

After that, we will look at creating our final structure.

How exciting! We've been on such a wonderful journey together to create structures for different users and purposes, and I'm really looking forward to creating the final structure today.

We'll also look at finishing techniques to finish our prototype structures.

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

In today's lesson, there are some keywords.

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

I will then read a definition of each keyword for you.

The first keyword is assembling.

Can you say the word "assembling"? Assembling is to gather together pieces to create a structure.

Our next word is joining.

Can you say the word "joining"? Joining is to link or connect pieces together.

Our next word is finishing.

Can you say the word "finishing"? Finishing is to complete the manufacture of a structure, adding decoration.

And finally, we have the word accuracy.

Can you say the word "accuracy"? Accuracy is the degree of precision in our drawings or measurements, and as designers, we must be very accurate.

Think back to what we have learned before.

We've learned about all different types of structures, including shell, solid, and combination structures and which ones are best for which purposes and uses.

We've created a detailed sketch of the structure that we want to make, and we've all chosen something different.

We've also began to make and strengthen the model of our structure.

Today we will continue to make the model of our structure to create a finished product.

Let's look at some methods for assembling and joining in our structures.

What is used to join materials? Could you use masking tape, scissors, a pencil, or glue? Pause the video now and have a think.

Welcome back.

The correct answers were masking tape, because it is an adhesive and it is used to join together materials, and another correct answer was glue.

It is also an adhesive used to stick together materials.

Scissors was false.

It is actually an instrument used to cut material, and a pencil is an instrument you use to write or draw.

What do you think? Is glue better than masking tape for joining together cardboard? Do you think that's true or false? That's false.

Both are types of adhesive which will join together types of cardboard, and we can use them for different purposes within our structures.

You're now going to look at creating a final structure.

Now, throughout this unit of work, we've learnt lots of different making techniques and designing techniques.

We've also created a really detailed design specification, which we must think about as we start to finish our product today.

I would like you to use a ruler to measure with.

This will create the most accurate and carefully-made product which will best suit the needs of our users.

You must also use scissors carefully, under the supervision of an adult or a carer.

You may use corrugated card to make your structure stronger today.

Of course you might use lots of other materials as well.

And also, during some of the lessons, I have shown you how to cut out tabs, slots, and flanges, and these are fantastic ways to join together different parts of your structure, applying adhesive to them to make sure that they stay.

Remember, we may just be making a model or a prototype of our structure, but we still have to make sure that it is robust and strong, and that's the job that real designers do.

And the reason they might make models or prototypes is because it can be quite costly and expensive and time-consuming to make a final structure without testing it first using models and prototypes.

And that means that we also need to do the same because we are designers.

And I want you to be testing your prototype and your model as you go along, checking that it is strong enough and that it is fit for the purpose that you are designing.

So here are some steps to make your final structure today.

Step one is to mark out and measure the shapes you need to make your structure.

Step two is, with an adult's supervision, use scissors to accurately cut out the shapes that you require.

Step three is to join together the shapes with tape or masking tape or glue.

And step four is to check your structure meets the points and your design specification that we wrote together in a previous lesson.

If you follow all these steps, you will have a fantastic structure.

You might already have some parts of your structures designed and made, but you may want to improve or edit or alter them in today's lesson.

What I want you to do now is I want you to pause the video to complete your final structure.

Welcome back.

Let's look at finishing techniques now.

Why are finishing techniques used in structures? Finishing techniques can be used for a variety of reasons.

The first one is to protect our structure, and we might use finishes to protect material from wear, mould, rusting, or moisture.

Now our structures might only be prototypes, but we want to think about how we can finish them today.

We might not be able to protect them from those things, but what we can do is we can add decoration to our structures, so you might add logos, patterns, and textures, or prints and colours to change the materials' appearance that we have used and make them more attractive for the user that we have in mind.

Also, finishes can be used in real life to enhance the structure, and this is done by making it more durable or improving other properties.

So for example, we might add different types of finishes that can make our structure stronger, or waterproof, or more durable.

Now, what finishing techniques are used for different materials? For plastic, we can sand it or polish it or emboss it.

In wood, there's lots of different finishes, such as painting it, staining it, coating it with other materials, sanding it to a smooth finish, oiling it, or varnishing it, and these protect the wood.

In metal, we sometimes polish it to give a shiny surface.

We can coat it with other materials, such as plastic, or we might be able to paint it.

If you think about a car, it's painted different colours, so that the user can choose from a range of different options.

Now, we have been mainly using cardboard to make our structures, because they are prototypes of our final design.

You might have used other materials too, such as fabric or plastic straws or wooden sticks.

You might have used lots of different things, but using cardboard was our main material and cardboard can be finished in many different ways, and I'm just going to show you just a couple now.

We could use paint to paint different colours and patterns and designs onto our cardboard.

We could also use felt tips to do the same things, or colouring pencils.

I want you to choose what works best for you, and also what you have to hand.

You might also think about adding logos like these ones onto your structure.

For example, I put that image of the little dog on the logos because I'm going to use that on my dog shelter structure.

But depending on your structure, you might choose a different logo to use.

You might also add decorations.

Maybe around your home you've got some glitter or gems or jewels, or little bits of ribbon or different pipe cleaners.

And those can be useful to add decoration to your final structure today.

And you might also use patterns or effects to make it look more like the real material that the structure would really be made from.

And that might be a good way to finish your structure today.

Remember, these are prototypes of a real structure, so try to make it as realistic as possible.

What I want you to do now is I want you to add finishing touches to your model.

You could paint, colour, or coat your structure.

You could add logos, patterns, or graphics.

Also think about what your structure would be finished with if it was actually real.

So, I want you to pause the video now to complete that task.

Congratulations on today's lesson.

I am so impressed with all the work that you have done throughout these lessons on structures, and I hope you have enjoyed designing, making, and now finishing your structure.

If your structure is not finished, don't worry.

You can always spend some time on it later.

In our next lesson, we will be evaluating our final structure, so try to make sure it's finished by then.

Now, I would love to be able to see some of your structures, so if you can, ask an adult or carer to share your work on Twitter, tagging @OakNational and #LearnwithOak.

I would be overjoyed to see some of your structures and to see some of the making and designing techniques that you have used throughout these lessons.

In the meantime, I hope you stay safe and happy, and I look forward to seeing you for our final lesson next time.

Goodbye!.
