Lesson video

Hi there, everyone, my name is Mr. Booth, and welcome to your design and technology lesson for today.

Thank you very much for joining me.

Today we are gonna be looking at exhibitions.

First of all, we're gonna look at a very famous exhibition that happened in the UK a long time ago, the Great Exhibition, and then we're gonna use that as inspiration to exhibit your museum alarms that you've been working so hard on.

This is the last lesson in the Systems and Control unit, Sensor alarms. Today's outcome: I want you to be able to prepare and host an exhibition of your work that you have been doing throughout this unit.

We only have two keywords for today.

The first one is the Great Exhibition, the first international exhibit held in London in 1851, so quite a long time ago.

And the second learning cycle is exhibition on its own, a place to show things for people to see.

And in this case, it's gonna be your museum alarms that you have been making.

We have two learning cycles for today.

The first one is all about the Great Exhibition, and the second one is about presenting your programmable systems in an exhibition.

So let's get on with that first one and learn all about this wonderful event that took place many years ago.

So the Great Exhibition was an international event held in London to showcase inventions, art, machines from countries all around the world.

It was a huge event at the time.

It was open from May to October in 1851.

It was organized by Prince Albert, who was, of course, Queen Victoria's husband.

First check for understanding.

The Great Exhibition was open in 1851 during which months? Was it A: March to August? Was it B: April to September? Was it C: May to October? Or was it D: June to November? Pause the video now, have a go at this and come back to me when you've got your answer.

So if you answered May to October, which was C, well done, you've got that correct.

Now, where was this wonderful event held? It was so big, they actually had to build a new structure, a new building to hold the exhibition.

It was a huge glass and iron building called Crystal Palace, which was built in Hyde Park.

Now, a really interesting fact is one of my ancestors actually helped build this structure, my great great grandfather.

How interesting is that? It looked like a giant greenhouse and it was over 500 meters long.

That's longer than five football fields.

It was moved and rebuilt in 1854 so people could get Hyde Park back.

But very unfortunately, it burned down in 1936 and it wasn't replaced because it was deemed that it would be way too expensive to do that.

So that's a real shame that we can't visit this beautiful structure today.

So what was on display at this Great Exhibition? You have to remember at the time, it was part of the industrial revolution, so the world was changing dramatically.

So there were machines like steam engines and looms, which are used in textile manufacturing to show the power of technology and design and how things had moved on so rapidly during the industrial revolution.

Fine art, furniture, jewelry and precious stones such as the Kohinoor, which was a very famous large diamond, were on display.

Products were displayed from all over the world.

Countries such as India, the United States of America, France, China, and many, many more had exhibitions within this exhibition.

Now, who attended this Great Exhibition? Well, over 6 million people visited.

Tickets were, on purpose, made cheap.

So lots of different people from lots of demographics could attend to see this wonderful event.

Famous people such as Charles Dickens, Charlotte Bronte, and Louis Carroll, all very famous authors attended.

Charles Darwin, the scientist, also attended as well.

And the profits from the Great Exhibition helped to build some of the museums in London today that I'm sure some of you have visited.

So another check for understanding.

The Crystal Palace building was made from: A: glass and plastic, B: glass and iron, C: glass and textiles, or D: glass and diamonds? Pause the video now, have a go at this, come back to me when you've got your answer.

It was, of course, glass and iron.

Well done.

So why was the Great Exhibition so important? Well, it celebrated industry and invention during the Victorian times.

It did celebrate it from all over the world, but it also showed how powerful Britain was in the mid 1800s.

It also helped people from different countries learn from each other and inspire world future fairs, which take place all over the world, every single year.

So now time for your first task.

I want you to imagine you are presenting a shoebox museum alarm at an exhibition at your school.

I want you to consider these questions: What would you show? What information would you provide at your exhibition? How would you demonstrate how your museum alarm works? And what questions do you think you will be asked during that exhibition? I want you to consider these.

You might wanna make some notes or you might wanna have a discussion.

Pause the video now, have a go at this task and come back to me when you've got all your answers.

So how did you get on? I'm sure you had some fantastic discussions.

Let's see what kind of discussions Alex and Aisha had when they were talking about presenting at their exhibition.

So first of all, Alex said, "I would show my drawings and prototypes to show how my designs developed." That's a brilliant idea to show the development and where you started to where you finished.

I think that's brilliant.

"I would talk about the decisions I made." That's also really important as well.

We have to make design decisions in design and technology all the time.

And being able to talk about those is a great way to showcase how your work developed.

Alex also said, "I would show people how the alarm works.

I might be asked what the museum is about and what the artifacts are." What artifacts are you actually protecting using your alarm? That's a great idea, Alex.

Aisha, let's see what you've said, then.

"I would display my shoebox museum on a table so everyone can see it." That's a really good idea, so people can get close to it and see all the wonderful work that you've done.

"I would talk about how I solved any problems that I had." Aisha also said, "I would ask people to test the museum alarm out." I think that's great having some kind of interaction with the people looking at your alarms. I think that's a great idea.

"I might even be asked how I would improve the museum alarm." And that's a really important question to ask as well.

It's great to be able to think of the questions that you might be asked so you can have those answers ready.

Well done, everyone.

So we're now onto our second learning cycle, which is gonna be all about presenting programmable systems. This is about you presenting your work, your museum alarm to others.

Exhibitions like the Great Exhibition still happen today.

You might have been to one.

They are really good ways of sharing designs.

An exhibition of the shoebox museum alarms is a great way to share your work with others.

It's a great thing to be able to celebrate what you have done, your success especially, and reflect upon your work from the questions that you might be asked.

Now we need to ask some questions before holding an exhibition.

Where will it be held? Who is gonna come to this exhibition? When will it be? What will you show and how will you test it? What will you say about your work? So let's take these one at a time.

Where will the exhibition take place? Think about how much space you will need for you, your museum alarm prototypes, and the audience.

You might also be presenting this with the rest of your class.

Now what I want you to do is pause the video here and just see if you can think of any ideas or any answers to this question really quickly.

So pause the video and come back to me when maybe you've got some ideas.

So what I thought of is it might be in a school hall or possibly even in your classroom, and it's important to work with your teacher to decide.

Now, you might have said, "Actually, I wanna do it in the playground." But of course, it massively depends on the weather.

A slight breeze might affect the museum alarm prototypes.

And of course, because they are electrical devices, you can't take them out if it's raining.

So where would be a good place for an exhibition of work? Would it be A: in a school hall, B: in a classroom, or C in a playground? Pause the video now, have a go at this and come back to me when you've got your answer.

Now, I would say for this, a school hall and a classroom are certainly good places.

A playground, if the weather is great, it might be good, but you can't trust the weather.

So the next question was, of course, who will be invited to the exhibition? Think about the time and the place you have chosen and who will be available.

Now, once again, pause the video now, have a quick think, maybe make some notes or have a discussion with the person next to you and come back to me when you've got a few answers to this question.

So of course, it could be families, school governors, other classes in your school or even other schools.

Once this has been decided, you need to let them know somehow.

So the next question is, when will the exhibition take place? Think about the availability of the space you will use and when the people you want to attend can actually make it.

So again, let's have some really quick ideas on this.

Pause the video, come back to me when you've got a few ideas.

So during the school day is usually quite good for pupils to attend, but if you want other people to attend, it might be the beginning or the end of the school day that might be better suited that you need to consider.

So a quick check for understanding.

When might be a good time to hold the exhibition? Would it be A: 2:30am, B: 9:00am, C: 2:30pm, or D: 9:00pm? Select the ones that you think are most appropriate.

Come back to me when you've got your answer.

Pause the video now.

Now I would say 9:00am and 2:30pm are probably quite good times to hold the exhibition.

9:00pm is too late at night, no one's coming to that exhibition.

And 2:30am in the morning, the vast majority of us are fast asleep, tucked up in bed.

Next question, what will you show and how will you test it? Allow time to make sure the museum alarm prototype works.

That's really important.

So once again, let's pause the video, let's get a few thoughts together, come back to me when you have those thoughts.

Pause the video now.

Don't forget to include any designs you made.

That's really important.

You might wanna include prototypes that you have.

So if there's any components that you didn't actually put in your final design, or you might have some models that you made before you made your final design, they would be really good to include as well.

And then possibly any examples of tools and materials could be on display too.

That might be a really interesting aspect to include.

And the final question we need to consider is what will you say about your work? A design specification can be used to help you frame what you say.

In this specification, we have appearance, talk about what the gallery looks like.

We have the function, what the gallery actually does.

Don't forget to talk about things like your programming and also the designs you've included and where you've placed everything.

The user, who is the gallery for? The performance, how is the gallery accessible.

Materials, what materials have you used and why have you used those materials for the different aspects of your design? And finally, environment.

Have you reduced, reused or recycled in any way when you have manufactured your final prototype? Now onto Task B.

What you need to do first is decide as a class where your exhibition will be held, who is gonna come and when it will be.

Once you've done that, you then need to decide what you'll show and use a design specification to think about what to say about your museum alarm.

You now need to prepare your exhibition.

Make sure you have tested that your museum alarm works.

And remember to logically fault-find if it doesn't.

And finally, hold an exhibition of your museum alarms, testing them in front of an audience.

Now of course, you're gonna pause the video now and carry out some of these tasks, but I do understand that task four might take place on a different day.

But pause the video now, come back to me when you have done the other three tasks.

So as we can see from Izzy, her and her class shared their work with others as part of an exhibition.

Izzy says, "Our exhibition was held in the hall at 9:15am and we invited our families to test what we had made.

We put out our shoebox galleries with alarms onto tables.

We also showed our sketches and our prototypes.

We set up the museum alarms the day before and had them tested and checked to make sure that they worked.

And finally, we talked about how we had made the prototypes and showed how they worked.

We got some great comments about our work." Some great feedback.

Well done Izzy, and I'm sure your exhibition was just as good.

Well done, everyone.

So that brings us to the end of this lesson.

Let's have a quick summary to see what we've done today.

The Great Exhibition in 1851 was an international celebration of inventions and design from around the world.

An exhibition is a celebration of work.

Designers need to be able to explain how their products work.

Designers need to be able to explain how their product was designed and made.

All really important.

Well done today.

You've been absolutely fantastic.

I look forward to seeing you next time.

Goodbye.
