Lesson video

Hello, my name is Mrs Enock and I'm delighted to be your design and technology teacher today.

We're going to be focusing on mechanisms, levers and linkages.

The name of today's lesson is to design a product criteria to meet the needs of the user.

In today's lesson we're going to, recap on different mechanisms, introduce our design brief, explore a range of persuasive ideas and generate our own design criteria.

Keywords.

In the lesson we will be using keywords that are really important that you understand how to say them and what they mean.

Our first word is mechanism.

I say it, can you repeat it? Mechanism.

Good job.

A mechanism is a device used to create movement in a product.

Persuasive.

Can you say persuasive? Great, persuasive is to convince someone to do or believe something through reasoning or temptation.

To persuade somebody to do or think something that you want them to do.

Design brief, can you say that? Great, design brief is a description of a product which needs to be designed.

It will state how the product will function.

That means how it will work to meet the needs of the user.

Our next word is recycle.

Can you say that for me? Good job.

Recycle is to convert waste into reusable material.

Now we've learnt our keywords, it's time to recap on different mechanisms. Mechanism, a mechanism is where materials or components are connected to make movement.

And we have explored using cardboard strips and split pins to make a mechanism.

Here's an example of a mechanism where you have a fixed pivot and a loose pivot.

By moving the slider, which is shown with the green arrow.

You get an output of an oscillating movement.

Here's an example of another mechanism.

How many loose pivots can you see? I can see two, two loose pivots and one fixed pivot.

We've got the input that slides and the output that slides as well.

Here's another mechanism that we've explored, this mechanism there are three levers and four pivots.

Can you point to the pivots? There are two fixed pivots shown by the black circle and two loose pivots shown by the white circles? Okay, it's time for us to introduce the design brief.

The design brief of this project is to design a persuasive picture with moving components.

So, we need to explore what does the word persuasive mean.

In a moment, have a look at the pictures and then pause the video and think when have you ever had to persuade somebody to do something, press pause and have a think now.

Did you have a think, well-done if you did.

I've seen myself being persuaded when I go to stores to shops, for example, to buy a certain toy, there might be a persuasive picture or words to help me.

There's been a time where I'd be more persuasive to encourage my family, to eat more vegetables.

And I've also seen persuasive adverts encouraging me to go and see a certain film at the cinema.

Persuasive.

The definition of persuasive is to convince someone to do or believe something through reasoning or temptation.

I don't know about you, but that chocolate bar is pretty persuasive, it's convincing me or tempting me to want to eat it.

In a moment, I'd like you to pause the video and think about who your target market audience is.

We know we're going to be making designing a persuasive picture with moving parts, but who do you think your target market could be? Have a think and press resume once you're finished.

Did you come up with lots of ideas? Well-done if you did, remember your ideas don't have to be the same as mine.

We want you to explore and experiment and come up with ideas, all of your own.

I thought that the target market audience I would focus on would be families.

And as you can see, families come in all shapes and sizes.

It's time to pause the video and have another think.

Where do you see adverts? Adverts, always persuading people to do things.

We might see them when we're out and about.

Pause the video and think where you've seen adverts, press resume once you're finished and we'll explore some of the ideas I thought.

Ready, off you go.

Did you think of different adverts? Well done if you did, let's explore some of my ideas.

I thought that's how I've seen adverts, when I'm waiting for a bus at a bus stop, I've seen posters.

I've also seen very large persuasive pictures as I drive past in my car on billboards.

I've also seen billboards, large adverts when I'm walking at the shops.

I've seen adverts when I'm reading my e-reading platform when I'm reading a newspaper.

And I've also seen adverts when I'm watching television.

What ideas did you come up with, I bet you had lots of great ideas.

Let's recap.

We want the picture to be, so the picture we're designing do we want it to be informative or persuasive.

Point to the correct answer now.

Great, we want our picture to be persuasive.

The design criteria was for the advert or the picture to be persuasive with a moving part, and to achieve the moving part I want to use levers and linkages.

Let's explore a range of persuasive ideas.

Heres our examples again, of being persuasive.

Now it's really important for you to come up with your own idea of how you want to be persuasive.

It does not have to be the same idea of mine.

It can look completely different.

What's important is that you think about your own ideas and you explore your own thinking.

Press pause and think what could you design to persuade somebody to do or think something? You can use my pictures to help you if you like.

Press resume once you're done.

Did you think of an idea of how you could be persuasive in your picture.

Well done if you did.

Let's recap on what we know.

Persuasive means to convince someone to do or believe something through reasoning or temptation.

Do you think it's true or do you think it's false? That's right it's true.

Being persuasive is to convince somebody to do or believe something through reasoning or temptation.

You can persuade somebody to buy something or do something through an advert, picture or poster.

Persuasion.

How would you persuade someone to buy this chocolate bar.

Let's pause and have a go.

Press resume once you are done and we'll carry on learning together, off you go.

Did you think of lots of ways to persuade somebody, well-done if you did, let's explore my ideas.

I came up with different ideas I had a brainstorm.

I thought about all the different ways I could persuade somebody to buy this chocolate bar.

I use strong adjectives, like tasty, delicious, scrumptious.

I also thought of some powerful phrases that might tempt people into thinking a certain way.

I thought of one as best chocolate ever, less sugar than other bars, sweet tasting, things to try and convince the person to buy them.

I also had to think about making it enticing for people to spend their money.

I thought of, buy one get one free and 25% off if you buy today, are you tempted yet, I hope so.

So let's recap, persuasion.

The picture that we are producing needs to be persuasive.

It needs to convince someone to believe something, whether they are believing that they really want to buy that chocolate bar or whether they believe that they need to do something like brush their teeth every day.

I'm sure the idea that you've come up with is fabulous.

Here's another idea where we can focus on our persuasive skills.

In a moment, you're going to press pause and have a think, how would you persuade someone to recycle more by using images? Images is another word for pictures, have a think.

Did you have a think, let's explosive of my ideas.

I thought that I could use pictures of the picture at the top almost to explain what recycling is and ways that we can recycle.

I thought it would be good to give an example of somebody actually recycling to give inspiration.

I thought a picture maybe highlighting what happens if we don't recycle, would persuade somebody to do that.

And my middle image is referring to how our world is precious and important and that we need to recycle to take care of our planet.

In a moment, you're going to press pause and have a think, how can we persuade people to help our planet? So I want to persuade people to, help our planet, protects our planet.

Press pause, and have a think of how you could persuade people to do that.

Ready, off you go.

Did you have a think of how to be persuasive? Well done if you did.

Here were my ideas, how can I persuade people to help the planet? I had another brainstorm, I put my picture in the middle and I had to think of different ideas that I could explore.

I thought about deforestation, about the cutting down of too many trees.

I thought about icebergs melting and beaches being dirty.

I thought about the phrase global warming and how that can be important to persuade people, to help our planet, to reduce global warming.

I thought about how we can recycle and how we can reuse things.

I thought about how there's too much plastic on our planet.

And I also thought about how there were animals dying because we're not always doing enough to help our planet.

What were ideas you thought of? I bet there were brilliant.

Now it's really important, we've explored different persuasive ideas.

Now's the time for you to think about what do you want to persuade people to do.

Now remember your idea does not have to be the same as mine or anybody else's it's what you want to persuade people to do.

So press pause, have a think and use the pictures to help you come up with something.

Ready off you go.

Have you come up with an idea? Well done if you have.

Now that you've thought of your idea, now's the time for you to complete a task.

In a moment I'd like you to pause the video, to complete this task.

Using a piece of paper I would like you to not only decide on your idea, but to make a brainstorm and expand your ideas, put your main idea in the middle of your paper and then use pictures and words to help you organise your thoughts.

Once you finished, press resume and we'll carry on learning together.

Ready, off you go.

Did you finish your brainstorm? Well done if you did, I bet it looks brilliant.

Now we've come up with an idea, it's time for us to generate our design criteria.

Our design brief is to design a persuasive picture with moving parts.

Now remember your persuasive picture will probably be different to my persuasive picture.

What we have in common is we will both be persuading people and we will both have moving parts in our design.

What's important is for you to explore and not be afraid to make your own decisions.

This is the design criteria that I've come up with to make sure that my design brief is a success.

I want my product, my persuasive picture to be moving.

The picture or advert must include a lever and a linkage to make the movement.

It must be controlled.

The movement needs to be smooth and controlled.

Be appealing, my product must look attractive to the viewer, to my target market audience, which are families.

My product must also be persuasive.

The advert or picture must be persuasive to the viewer.

Now we've got our design criteria, let's move on with our learning.

Appealing design techniques, what can we do to make our design appealing, to make it interesting for people to look at? I want to make sure there are bright colours in my picture.

The pictures are clear and easy for everybody to understand.

Want to make sure there's a bold title, so it catches the viewer's eye.

I also want it to have a clear theme to have one idea so it's not confusing when people look at it.

Persuasive design technique, we want to use strong adjectives in our persuasive picture using strong adjectives, such as fabulous, amazing, brilliant are much more powerful than just saying something is okay and pretty good.

We possibly want to play on people's emotions to make them think that they might feel a little bit guilty if they don't help the planet or that people feel really happy if they buy our product or follow our advice.

We want to give people a reason to agree with what we're persuading them about.

We want to give them reasons to agree with us.

Also an impressive heading and title is very important to help catch people's eyes, to catch their intention and so they'll look at our title and then they'll be intrigued to read the rest of our persuasive picture.

In a moment I'd like you to pause the video, to complete your task.

You are going to write your design brief and criteria.

You might want to use my ideas, or you might want to think of your own.

Remember to include who is your target market audience.

Remember it might not be the same as mine.

And what are you persuading your target market audience to do? Finally, what does your design need to include? Once you've done this, press resume and we'll carry on learning together, ready off you go.

Well done for that task.

Let's recap on what our design criteria is.

Let's read this statement, the picture does not need to have moving parts, true or false point to the correct answer.

That is false, it does need to have moving parts.

I want it to have linkages and levers to make part of my picture move.

Let's read this statement.

The picture will be designed to persuade the viewer, point to the correct answer do you think it's true or false? It's true, the picture does need to persuade whether you've chosen to do a picture or a poster or an advert it must be persuasive.

Let's finish our lesson by recapping on what we've learned today.

First of all, we recapped on different mechanisms. We were introduced to the design brief.

We explored a range of persuasive ideas.

And we generated our own design criteria.

I really enjoyed working with you today.

We've learned such a lot and I've had a fantastic time.

All that's left to say you should be very proud of yourself and I hope to see you soon.

Bye.
