Hello, I'm Mrs. Enock your design and technology teacher for cooking and nutrition: a varied and healthy diet.

Today's lesson, we're focusing on evaluating your product.

So let's get started, shall we? It is recommended that you complete this lesson, lesson six, straight after lesson five.

Lesson five was a practical lesson making a sandwich.

This lesson is about you eating and evaluating your sandwich.

Okay, let's see what we're learning about in today's lesson.

First, we're going to check product against the design criteria.

We're going to identify strengths and recognise areas for development.

We're going to consider the views of others of how to improve our work.

And we're going to make changes to our product in response to our evaluation.

Okay, let's get started.

Today, the equipment you are going to need is the packed lunch you've already made, whether this is a photograph or the actual packed lunch, pencil and paper and people to question.

Keywords for today's lesson.

Our first word is design criteria.

Can you say that? Fantastic.

Design criteria are the important things we need to include when creating our product.

Our next key word is evaluation.

Can you say evaluation? Well done.

Evaluation is when we identify the strengths and areas of development in a product.

It's a very important part of design and technology.

We also have the key word product.

Can you say product? Excellent.

Product is how we refer to the item which we have designed and created.

So instead of saying, healthy packed lunch, we would say product.

Our next word is bias.

Can you say bias? Well done.

Bias is to show favouritism towards something, even if it isn't the best choice.

An example of this would be choosing your packed lunch over everybody else's, even if somebody else's did happen to be better than yours.

We're now going to check product against our design criteria.

Our design criteria included the following things.

My healthy packed lunch had to have cheese in it.

It had to have the vegetables pepper and carrot in it for the colour.

It must have the fruit strawberries in it.

It must have cucumber in it.

It must avoid using snacks such as crisps, sweets and chocolate, because these are high in sugar and salt.

It was suggested the food could be arranged in pictures, or a theme, or have food kabobs or even all three.

Our design brief was to design a healthy packed lunch for primary school child.

We needed it to be super tasty, super colourful, super healthy and super fun.

Here's a photograph of the things that I made as part of my healthy packed lunch.

Do you remember making these? It was lots of fun wasn't it? We are going to check our design brief against the made product.

You can see the made product on the screen in front of you.

I need to ask myself the question, was my packed lunch super tasty? Is it super colourful? Is it super healthy? And is it super fun? I'd like you to pause the video and have answered each of these questions and see what you think, and I am going to do the same.

Ready? When you've finished, press resume and we'll carry on learning together.

Off you go.

Well done.

Did you check the product against the design brief? Well done if you did.

What we're going to do now, is we're going to check the design brief against our product using a table to help us.

I'll give you an example of how to do this.

In the first box you can see, was it colourful? And underneath did it meet the criteria, I've checked yes, because I believe the packed lunch did meet the success criteria.

And the example of why it did or did not meet the criteria, is the food and vegetables gave the packed lunch a lot of colour.

What I'd like you to do in a moment is pause the video, and using the worksheet to help you, I'd like to check your design brief against your product.

Use the same questions I have, was it colourful? Was it healthy? Did it look fun to eat? Was it tasty? And either tick or cross whether it met the design criteria and give a reason why.

Once you've recorded this, press resume and we'll carry on learning together.

Okay, off you go.

Well done.

Let's have a look at an example of how I checked my design brief against my product.

Was it colourful? Yes.

It was colourful, the fruit and vegetables gave the packed lunch a lot of colour.

Was it healthy? Yes.

There was a lot of fresh product used.

There was no added sugar and salt to my packed lunch.

Did it look fun to eat? I've ticked yes.

The shaped look fun although, there could've been an extra healthy treat to make it look even more fun and appetising to eat.

Finally, was it tasty? Yes, this did meet the criteria.

The sandwich was tasty and the vegetables were crunchy.

Although, they could've had a dip to make them more tasty.

Were you successful in checking your design brief against your product? Well done if you were.

We can now ask ourselves this question.

Did your product match the design brief? For my healthy packed lunch, I believe the answer is yes.

What do you think about your packed lunch? If you thought no that it did not, please do not worry.

Being a great designer is about not being afraid to make changes to your design.

We could always improve and make things better.

We're now going to identify strengths and areas for development in our product.

Evaluating my product, which we know is the healthy packed lunch.

It's time to analyse, reflect and not be afraid to develop new ideas.

I'm going to start with the strengths of my product.

I though it was colourful with a lot of different fruits and vegetables.

I thought it was healthy, because there was very little salt and sugar in my healthy packed lunch.

I also thought the strength of my product was cutting food into different shapes to make it look fun to eat.

Now, on to areas for development.

I thought the chopped up vegetables could've been more exciting.

I think next time, I try and use even more different cookie cutter shapes just to experiment.

I also realised, there were not many carbohydrates in my packed lunch, so I might become quite hungry quickly.

Finally, I missed having a different type of drink.

What I'd like you to do in a moment is press pause and using the worksheet, analyse your own product.

Focus on the strengths, and don't be afraid to focus on the areas for development.

Once you've had time to analyse, reflect and record your answers, press resume and we'll carry on learning together.

Okay, off you go.

Well done if you managed to evaluate your product.

It's really important to not be afraid to analyse and reflect and always keep learning.

We can ask ourselves this question now.

Did you identify an area for development? In my case, yes I did.

I did identify an area for development.

Well done if you did.

Part of being a great designer is not being afraid to change and develop your ideas.

We're now going to consider view of others to help you improve your work.

Considering the views of others.

It is important to ask others about your product.

When you analyse your own product, you can express bias because you've chosen exactly how to make it.

Asking closed questions against a set criteria allows you to gather similar answers about what you are trying to find out.

Let's have a look and see.

This is how you can ask questions to support your evaluation.

Does my sandwich match my design criteria? Did I design a healthy packed lunch for primary aged children? Before we can ask these questions, let's remind ourselves what the design brief was.

Do you remember? That's right.

It was design a healthy packed lunch for a primary school child.

We needed to see if it was super tasty, super colourful, super healthy and super fun.

What I'd like you to do in a moment is pause the video and complete this task.

You could either write down your questions, or ask people and remember the answers.

I'd like you to ask at least two different people to evaluate your product using the design brief below.

Is it super tasty? Is it super colourful? Is it super healthy? Is it super fun? Once you've asked different people to evaluate your product, press resume and we'll carry on learning together.

Ready? Great, off you go.

Did you get people to evaluate your product? Well done if you did.

Here's an example of when other people evaluated my packed lunch.

These were the strengths of my product that people commented on.

Under super tasty, they said the lettuce was crunchy and fresh and having grated cheese was nice.

They acknowledged under super colourful that there were lots of different colours.

They also said, it's a food way to get your five a day.

Some people thought the fruit shapes were cute, and they thought the sandwich was a fun shape cutting it into triangles.

These are the areas of development for my product that other people commented on.

They acknowledged that the people don't like lettuce, and someone thought they might still be hungry after eating my packed lunch.

Somebody said they'd like to have even more fruits and vegetables added.

It was commented there was nothing to dip the vegetables in.

And nobody really commented on how colourful it was.

We're now going to focus on making changes to the product in response to our evaluation.

This is a really important part of the evaluation.

Now we've listened to what people think, we're going to respond to their answer.

If you have a look on the screen, I've designed a new healthy packed lunch.

Under my vegetables and dip, I've got my cucumber, carrot and pepper shapes.

And I've also included adding a healthy dip for those to be added in.

In my healthy sandwich, I thought I'd change it and try cheese in a wrap, still with lettuce and cucumber, but this time I'd add some tomato as well.

For my fruit I've got strawberries, grapes and now I'm feeling more confident to wash and prepare fruit, I'll add blueberries as well.

I've also decided to include a healthy treat, and I'd like to make an oat bar to make sure I don't get hungry in the afternoon.

What I'd like you to do in a moment is press pause on the video and using the worksheet, design your own healthy packed lunch.

You can draw, write labels, or tell somebody next to you what you would do.

When you've done this press pause and we'll carry on learning together.

Ready? Great, off you go.

Did you have fun designing your healthy packed lunch? Oh I bet it looks fantastic.

We've had a busy lesson today.

Let's see what we've learned about.

First of all, we've checked our product against the design criteria.

We identified strengths and areas for development.

And we considered the views of others to improve our work.

We made changes to our product in response to the evaluation.

My goodness, we've done a lot of work today.

Well don for evaluating your work and not being afraid to make changes.

I really enjoyed working with you today, and I'd love to see some photographs of either your packed lunches and your new designs.

If you'd like, please ask your parents or carer to share your work on Twitter tagging @OakNational and #LearnwithOak.

I look forward to seeing your work.

Well done for today, you should be very proud of yourself.

Take care, bye.
