Hello, my name's Mr. Booth, and it's brilliant that you've joined me today for your "Designer Technology" lesson.

We've got a great lesson today all about card slider mechanisms. The outcome of today: I can explore and create slider mechanisms using paper and card.

So today you are gonna be able to identify all the features of a slider mechanism, and by the end of the lesson, you are even gonna have made your own slider mechanism.

How great does that sound? We've got some key words for today's lesson.

Should we do these together? So my turn, slider, your turn.

Brilliant, well done.

A slide is a bar that moves backwards and forwards along a straight line.

Next one, my turn, guide, your turn.

Excellent work, guide, a piece of material used to keep mechanisms in place and control movement.

And then finally, slot.

Brilliant, well done.

And the slot is the whole through which a lever or slider is placed to enable movement.

Now, these keywords are gonna come up a lot in this lesson, so keep an eye out for them.

Today's lesson has two parts to it, and the first is looking at features of slider mechanisms. So let's get going.

There are lots of different types of mechanism.

A slider is one type of mechanism.

So let's have a look at some examples that you might know.

The first one is a drawer in your kitchen.

This is a slider mechanism because it slides in and out.

You might also have a gate in your garden which will have a slide lock, sometimes also known as a bolt, on it to be able to lock it, and that again is a slider mechanism.

So this is a slide lock for a gate, it is a slider, a slider mechanism.

A slider moves in a straight line.

It can move forwards and backwards, or up and down.

So you imagine with this slide lock for a gate, we can shut it by moving it in one direction, and we can open it by moving it in the other direction.

A slider is a rigid bar.

The word "rigid" means that it does not bend.

And as you can see, in this case, we wouldn't be able to bend that lock.

And there's the slider.

So quick check, "True or false? A slider moves in a straight line." Pause the video, have a think, and try and answer.

Did you answer True? If you did, well done, but why? Well, the slider moves from side to side or up and down by sliding in a straight line.

A slider is a rigid bar.

So this slide lock is made from metal, and it has three main parts.

Let's have a closer look at those.

We have a slot, we have the guide, and we have a slider.

Do you remember all of those when we did our keywords together? The guide is a piece of material that holds the slider in place.

So you might also be able to imagine this as a train track and something moving along the track.

The wheels move between the guides, the guides hold those wheels in place, and that is the same if we are using a slider mechanism.

So another quick true or false check, "The guide keeps the slider in the correct place.

Is that true or false?" Pause the video and have a go.

Did you answer True? I bet you did, well done.

So why is that? Well, the guide makes sure that the slider moves correctly.

It works a bit like a train track, keeping the slider in place, well done.

So the slider mechanism on this card has three main parts.

So let's have a look at these parts more closely.

We have the slider, of course, we have the slot, this is the hole cutting the slide, sorry, who's cutting the card to make sure that the slider can get through it.

But then we also have our guide as well to hold the slider in place while we move it.

So the slot hides and covers the slider mechanism.

And these are often found in celebration or moving cards or even books because you don't necessarily wanna see the hole of the slider.

So a slot can be created by folding a piece of card slightly and then cutting along the fold with scissors.

This is a really nice way of being able to cut that little tiny slot somewhere in the middle of your card.

So as you can see here, this is what we've done.

We've folded the card slightly, and then we're cutting a little tiny piece of card off to make the slot.

And that picture there would be the outcome.

The slot needs to be slightly longer than the width of the slider bar, and that's to let the slider bar move easily.

You don't want it exactly the same size, otherwise it'll be too hard to move.

Right, your first task.

What I would like you to do is label the parts of the slider diagram.

So there's your diagram, and I want you to label all those parts.

So number one, where is the slider, number two, the guide, and number three, the slot? Pause the video, have a go at that, and then let's see how you got on.

How did you get on? Did you do the same as me? So of course we have the slider that's gonna move left and right in this case, we have the slot to allow the slider to pass through the card, and then we've got the guide to hold the slider in place to make sure it moves correctly, well done.

So we're now onto our second part of the lesson, "Make a slider mechanism." So first of all, we're gonna have to use scissors for this activity, and it's really important that we use them safely.

So here are my top tips for making sure you use your scissors correctly.

First of all, hold your scissors carefully.

Try to sit down when using scissors.

Never point your scissors at anyone.

Scissors are not a toy, I'm sure you knew that.

And use the right scissors for the material.

If you follow those safety tips, we'll all be nice and safe.

When you make a slider mechanism, it's very important to cut carefully and accurately so the slider moves smoothly.

So to cut carefully, hold the paper in one hand and the scissors carefully in the other.

The scissors should be in your dominant hand, that's the hand you write with.

Cut along the line carefully, stopping at the end of each line.

Make sure you take your time on this, and that will make you a better product.

And then finally, if you are turning a corner, turn the paper around, not the scissors, that's a really neat trick that.

So quick true or false.

"When you cut around a corner, turn the scissors." Is that true or is that false? Pause the video, and have a go.

It is of course False, and why is that? Well, of course you should be cutting slowly and turning the paper around, not the scissors, well done.

So this little animation shows the slider mechanism in place with the card.

We have our picture.

So we've got our blue whale with water coming out of its spout.

We have the slider, which is the little cardboard bit sticking out the side.

But brilliantly, what we've done is we have the guide and the slot, but these are hidden behind the whale, and that of course still makes it slide correctly, but you can't see them, we've hidden the behind the picture.

How good does that look? And the slider in this case, really important to remember, does not use split pins, we don't need to make a pivot in this case, okay? So quick check for understanding to make sure you've got that: "Slider mechanisms in celebration cards use split pins." Is that true or is that false? Pause the video, have a go.

It is of course false, and why is that? Well, a slider does not use split pins because the slider does not turn on a pivot, a slider moves in a straight line, well done.

To make a slider, we need to use these materials and pieces of equipment.

So let's just check that you've got them all so you can make your slider mechanisms. We need a pencil, we need some card, we need some scissors, and we need a glue stick.

Have you got everything? On to task B.

First of all, I would like you to draw and cut out the moving picture for the front of your celebration card.

I want you to be as creative as you can, think about what you want to move and how it could move in a sliding motion.

Pause the video, have a go at that, and come back when you've completed it.

Brilliant, so this is Andeep's picture for his slider, and he told his peers that it was gonna move from side to side.

And as you can see, he's cut it out nice and neat.

It's nice and creative, our blue whale with water coming outta the spout.

Well done, Andeep.

How is yours? I bet yours looks brilliant just like Andeep's.

So the second part of this task is to make a slider using the cardboard template.

What you need to do for this is cut the slot in the card, which is slightly longer than the width of the slider bar.

Remember that trick that I showed you earlier on how to do that? Make sure you use that.

Next, using extra card, add your guides and your slider bar, make sure that it does slide backwards and forwards, or in whichever direction you've decided to do yours in.

And then finally, glue your picture in place and check that it works.

Brilliant, have a go at that.

Enjoy making that, and when you're done, come back, and let's see how you got on.

I bet you got on brilliantly, and I bet your designs look absolutely fantastic like the blue whale example here.

So let's just check.

You should have cut the slot in the card, use the extra card to add guides and a slider bar, glued your picture in place and checked that it works.

Did you manage to do all that? Does your slider mechanism work? Well done, brilliant work.

So that is the end of today's lesson.

Well done today, let's have a quick recap of what we've learned.

Mechanisms make something move, and include sliders.

Sliders are rigid bars which move backwards and forwards along a straight line.

Sliders have a guide which is used to keep it in place.

And when constructing sliders, it's important to cut and measure accurately.

Well done today, I really hope to see you in some future design and technology lessons, bye-bye.
