Hi, everyone, I'm Mrs. Courts and I'm very pleased to join you for today's lesson on Finishing a vehicle.

This is part of the Wheels and axles: vehicles unit.

In today's lesson, our lesson outcome is I can build and finish my vehicle using a range of materials and strategies.

And in today's lesson, we have got five new keywords.

Are you to sitting nicely? Are you listening really carefully? Brilliant.

I'll say them first and then you repeat them after me.

Super.

Vehicle.

Vehicle.

Brilliant.

A vehicle is a machine with wheels used for transporting people or goods.

That means taking them from one place to another.

Brilliant.

Joint.

Joint.

A joint is a point at which two parts of a structure are joined together.

Parallel.

Parallel.

Well done, well, parallel are lines that always are the same distance apart and they never meet.

Reinforce.

Reinforce.

Reinforce means to strengthen or to support an object or a structure.

And our final word today is body.

Body.

Super.

The body is the main structure of a vehicle that holds its components.

Well done and super listening.

Well, in today's lesson, we've got two parts to our lesson, two learning cycles and our first part is joining axles and wheels to a vehicle.

Brilliant.

This is the chassis of a vehicle and this is the part under the car or the vehicle.

The axles run under the chassis and are held in place by axle holders.

The chassis needs to be assembled, that means built, before the body of the vehicle is built.

And as you can see on our diagram, we've got axle holders, we've got wheels, we've got axles, and we've got chassis.

Can you see all those different parts? Brilliant.

The axles run under the chassis and are held in place by axle holders, and the axle goes through the holder but it still needs to turn.

The axle holders can be made from wooden pegs, cardboard triangles or straws.

Can you see those three different ways of adding the axle holders? To join the axle holders to the vehicle, you might use one of these joining methods.

Some simple joining methods, these are the ones which are easier to do.

By using sticky tape, masking tape or a glue stick.

Harder joining methods are staples, double-sided tape or PVA glue.

To put a hole in the triangular piece of cart, we can use the sticky tack and pencil method.

You might remember this.

First we put the sticky tack on the desk, then we put the card on top of it and using a pencil we pierce, that means put a hole in the card.

We then carefully remove the card from the sticky tack.

It's important to do that carefully so that your piece of card does not rip.

We are now ready for our first check for understanding.

Are you ready? Super.

Which of the following is a picture of a straw axle holder? Pause the video now and have a little think.

Welcome back.

So which was the picture of the straw axle holder? It was C.

Well done! When you add axles to the underneath of a vehicle, remember, Izzy says, "The axles must be lined up so they are parallel with each other." Parallel lines are always the same distance apart and never meet.

These lines here are parallel.

These are parallel axles.

If the axles are not parallel, the vehicle will not travel in a straight line and will not work properly.

These axles are made using straws and wooden dowels through wooden peg axle holders.

Can you see the wooden peg axle holders? Super! If you look at the yellow straw, you can see the straw axle and the other one is the wooden dow axle.

Brilliant.

We are ready for our next check for understanding.

Hope you've been listening very carefully.

Super.

Which two of the following are good materials for axles? Is it A: masking tape? Is it B: pre-cut wooden dowels? Or is it C: thick straws? Pause the video now and have a little think.

Welcome back.

So which two of the following are good materials for axles? (gasps) You're right, it is B, the precut wooden dowels and the thick straws.

And as you can see in our picture, there was the pre-cut wooden dowels at the back with the green axle holders and a fixed drawer at the front with the blue axle holders.

Well done, everyone.

These are different materials that you might use to make wheels for your vehicle.

Cardboard wheels, plastic wheels, or wooden wheels.

Have a little look at those pictures.

Which are you going to use for your vehicle? The wheels in the vehicle are usually the same size, or at least the same size on each axle.

As you can see here, these wheels are unbalanced.

The vehicle will wobble.

However, these wheels on the first picture are the same size and on the middle picture, the wheels at the back are bigger, but that's okay because the front wheels are the same size and the back wheels are the same size.

Using the chosen parts for the chassis, Sofia built the chassis and tested it.

The chassis started to move and it rolled forwards and backwards.

Sofia chose to use these materials: tall, strong box, foil for the windows, red paint or paper, white ribbon or card, grey or black paint, and pen for the bus name.

She decided the chassis would be made from a cardboard box, the wheels would be made from wooden discs, the axles would be made from pre-cut wooden dowels and the axle holders would be made from thick straws.

Izzy says, "How do you keep the wheels on the axles?" That's a very good question, Izzy.

I wonder if we know the answer.

How could you keep those wheels on the axles? Have a look at the picture.

You might get a clue.

That's right, you could use a piece of sticky tape or sticky tack to keep the wheels in place.

Another option is small pieces of straws that are squeezed, that are fitted tightly to the axle and that joins the wheels to the axles, holds them in place.

Well done.

We are ready for our first task now, Task A.

And I would like you to firstly use your design and materials list and add the following to your chassis: axle holders, axles, wheels and caps to hold the wheels on the axle.

When you finished that, I would like you to check that your chassis rolls.

If it struggles to roll, what can you do to make it work better? Pause the video now and complete Task A.

Welcome back.

I hope you've had lots of fun making your chassis for your vehicle.

Well, this is Izzy's chassis.

She tested it and it rolled, but Izzy forgot to add the end caps to her axles and initially, the wheels fell off! But Alex reminded her.

Oh, that's very kind of Alex.

Izzy is now ready to make the body for her vehicle.

Well done, Izzy.

Great work.

Are you ready to make the body for your vehicle? Excellent.

This leads us nicely into our second learning cycle, our second part of the lesson of creating the body of the vehicle.

Design specifications help the designer to create great products and produce good-quality finished products.

Jacob says, "Design specifications are very important and we must use them to help us to design our vehicles." The body of a vehicle is the main structure of the vehicle that holds its components.

As you can see in the picture, there's the windows, the wing mirrors, lights, doors, door handles, bumpers, boot and boot latches and a roof.

These are the main parts of the vehicle's body.

To make the body of the vehicle, think about the type of vehicle you are making, the features such as the windows, the doors, sirens, number plates.

Think about the colour, think about the materials, the size of the vehicle.

And Laura says, "Always have in mind your design specification and your design." A very good point there, Laura.

Well done.

We are ready for our next check for understanding.

Hope you're sitting comfortably.

Brilliant.

Which of the following might you find on the body of a vehicle? Is it A: wheels, B: doors, C: windows, or D: axles? Pause the video now and have a little think.

Welcome back.

So which of the following might you find on the body of a vehicle? You are right, it is doors and windows.

Well done.

The wheels and the axles were on the chassis.

Brilliant work.

Laura says, "The wheels and axles would be found on the chassis, not the body of the vehicle." These vehicles have all got different bodies.

The bodies are all different heights, lengths and sizes.

Have a little look at the pictures.

Do you recognise them? That's right, a car.

A car has two doors, on this car, and a boot.

It has glass all the way around and silver door handles and wing mirrors.

And this is painted bright red.

So in red paint.

This tractor has a tall cab area and lower bonnet for the engine area.

It has tall glass around the cab area and it has got green paint.

And finally, this bus has a lot of glass all around the bus.

It has got big, green wing mirrors and very long side panels.

It is very bright.

It's painted brightly.

To make the different shapes of the body of the vehicle, different objects and materials can be used.

You might use foil, bottle lids, straws, yoghourt pots, tubes, smaller boxes and small bottles and other recyclable materials.

Just like when the chassis of the vehicle is reinforced to make it stronger, the body of the vehicle may need to be reinforced so that it will hold its shape and features without braking and getting damaged.

Joints are where the material is joined together, and these joints are where the cardboard joins together to make the box.

Can you see it? Well done.

These are two ways to reinforce joints in a vehicle's body.

They are also good ways to join parts together to create a strong, sturdy joint.

These triangles are a good way to add extra support and join pieces of card together.

And this method is called triangulation.

Can you say that word? Triangulation.

Brilliant.

Similar to corrugated card, pieces of card can be built up in layers and this adds extra strength.

We are ready for our next check for understanding.

Are you sitting comfortably? Brilliant.

This is a true or false question.

Joints are only found on a chassis.

Is this true or false? Joints are only found on a chassis.

Pause the video now and have a little think.

Welcome back.

So true or false: Joints are only found on a chassis is false.

Well done.

Why? In terms of a vehicle, joints are found on a chassis and also on the body of a vehicle.

A joint is where two or more pieces join.

And by reinforcing these, it will make them stronger.

To finish the vehicle, you might add some paint.

You might decorate using felt pens, ribbon, coloured card, tissue paper, foil wrappers, or other materials to decorate and personalise your vehicle.

Personalise means to make it your own.

We are ready for our second task now, Task B.

I hope you're listening very carefully.

Brilliant.

Using your design, make the body for your vehicle.

Alex says, "Remember to use different shapes and sizes of recyclable materials or card and to reinforce these where needed." Then add extra details to your vehicle's body and use a range of finishing techniques to make it appeal to the person using it.

Alex says, "You might use different decorating materials, paints, pens, or a range of materials to finish your vehicle.

Remember to make it appeal to the person using it so that they want to use it." Well done.

We'll pause the video now and complete Task B.

Welcome back.

Well, this is Sofia's vehicle.

She made a bus for her little brother who loves double decker buses.

She used a range of materials and added extra strength to the body of the bus.

She decorated it by painting it red, adding plastic windows and colouring the wheels a dark grey.

"My finished bus looks like my design," says Sofia.

Well done, Sofia.

That is a very good bus.

Did you manage to finish your vehicles? Brilliant.

Maybe you could show them to your friends.

We've reached the end of our lesson for today, and I hope you've had lots of fun.

I wonder if you'd show me a thumbs up if you feel we've met these learning points.

The body of the vehicle needs to be attached to the chassis.

That means joined to the chassis.

Well done.

Card and cardboard can be used to make a realistic vehicle body and can be reinforced to make it stronger, stiffer, and more stable.

Well done.

And the body of the vehicle can be modelled in different shapes.

Brilliant.

Wheels and axles are attached to a chassis to make a vehicle move.

Excellent.

And a range of materials can be used to finish a vehicle.

Brilliant.

Well, well done for all of your hard work today.

I hope you found lots of fun and I'll see you again soon.

Bye!.
