Hi everyone.

I'm Mrs. Courts and I'm very excited to join you today for our lesson on wheels and axles in vehicles.

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

Our lesson outcome for today is: I can identify wheels and axles in a vehicle.

To do this, we've got four new keywords.

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

Axle.

Axle.

Super.

An axle is a rod that connects wheels, that joins wheels and allows them to turn.

Wheel.

Wheel.

Brilliant.

A wheel is a circular object that turns on an axle.

Vehicle.

Vehicle.

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

And the final word is rotate.

Rotate.

Rotate means to turn or spin around a central point.

Super listening.

Well done.

In our lesson today, we've got two learning cycles and our first learning cycle is understanding wheels and axles.

These are all vehicles or toys that move.

You might recognise some of these: a toy car, a train, a tractor, and a toy cart.

Now, a vehicle is something that carries people or goods from one place to another.

Do you recognise any of these? You may have been on a train journey or a trip in the car.

Vehicles have wheels and wheels turn in a rotary motion.

Can you say rotary motion? Brilliant.

Rotary motion.

Andeep says, "What is a rotary motion?" That's a good question, Andeep.

Jacob said, "Rotary motion is when something turns in a circular movement.

The object rotates." Well done, Jacob.

This wheel is turning.

It is rotating.

Andeep says, "It turns in a rotary motion?" Jacob says, "Yes, it turns in a circular shape." To make a vehicle move, it needs to have two main parts: the axle, and this is the rod that holds a wheel in place and allows it to turn.

And I think you might be able to guess the other part.

That's right.

A wheel or wheels.

These are circular objects that turn on an axle.

So it needs an axle, which is the rod that holds the wheel in place and allows it to turn.

That's the big rod through the middle in the picture that you can see between the wheels.

And the wheel, or wheels, which are circular objects that turn on an axle.

We are ready for our first check for understanding.

Are you sitting comfortably? Brilliant.

Why do vehicles have circular wheels? Is it A, to help them to move by the wheels turning; B, to stop them moving; or C, to make them move up and down? Pause the video now and have a little think.

So why do vehicles have circular wheels? The answer is A.

Well done.

It's to help them to move by the wheels turning.

Wheels are fixed to an axle and this vehicle's wheels are turning forwards and backwards.

Can you see that? Going forwards and backwards.

Axles and wheels are important for moving vehicles.

The axles connect wheels to an object or a vehicle and allow the wheels to rotate, to turn.

We are ready for our next check for understanding.

What job does an axle do? Is it A, allows the wheels to turn; B, attaches the wheels to the vehicle; or is it C, stops the vehicle? Pause the video now and have a little think.

Welcome back.

So did you get the answer? What job does axle do? Well, it allows the wheels to turn and you are right, it attaches the wheels to the vehicle.

There's two answers there.

Well done.

We are ready for our first task, Task A.

I would like you to look at the different vehicles on the table.

And first, can you spot the wheels and axles on the vehicles? And then how do you think the vehicles move? Pause the video and join me when you've completed Task A.

Welcome back and I hope you've had lots of fun exploring how the vehicles move and found some of the wheels and axles.

Brilliant.

Well, Alex and Jacob, they worked together to explore the vehicles.

Jacob said, "It was a lot of fun playing with the vehicles and exploring how they move." Alex said, "We spotted all of the axles and wheels and they're all different sizes and made from different materials too." And Jacob said, "The wheels rolled and this helped the vehicles to move.

The axles joined the wheels to the vehicles and this let it move.

It was good to explore!" Well, well done Jacob and Alex, you had lots of fun there.

We are ready for our next learning cycle.

This is exploring wheels and axles in vehicles.

Some vehicles or moving objects have less than four wheels.

The wheels and axles work in the same way.

Here's a bicycle, a bin, and a wheelbarrow.

Some axles work differently than others.

Have a look at the pictures.

Do you recognise them? That's right, they're windmills.

This windmill has an axle that is attached to sails that turn.

Alex said, "We must remember that just because something moves, it doesn't necessarily mean that it has an axle." That's a very good point, Alex.

Did these moving objects have an axle? That's right.

No, the rocking horse, the boat, and the door do not have axles.

Well done.

We are ready for our next check for understanding.

This is a true or false.

All moving objects have wheels and an axle.

Is this true or false? Pause the video now and have a little think.

Welcome back.

Well, did you get the answer? True or false, all moving objects have wheels and an axle? That's right.

It is false.

Why is it false? That's right because vehicles usually have wheels and an axle.

But some moving objects like rocking horses and doors don't have wheels or an axle.

Well done.

Alex said, "Have you noticed that some axles only have one wheel?" Very good point there, Alex.

Have a look at the water wheel and the bike.

These wheels still have an axle that allows the wheel to turn.

The bike has two wheels, however, each wheel is attached, is joined to the bike with an axle.

So it's two wheels and there's two axles.

Another simple axle could be a round stick, a wooden dowel or a thick straw, joining two cotton wheels or circular pieces of card together.

Sophia says, "Next time use a construction kit or junk modelling, have a go at making a simple axle." "I started to make a simple axle using a wooden stick and a piece of card.

What do I need to do to finish it?" What's missing? That's right.

The missing part is the wheel on the other end of the circular piece of card on the other side of the dowel.

Well done.

Here is a diagram of the bottom of an old train.

Alex then used the rectangle to draw his wheels and axles.

Can you see the picture of the old train? And here's the diagram.

He then, using that rectangle, drew the axles, the rod across, and then he put his wheels on.

Can you see that? Super.

Alex then labelled the wheels and axles on his diagram.

We're now ready for Task B.

Are you sitting comfortably? Super and good listening.

The first part, I'd like you to choose a vehicle and turn it over so you can see the underneath of it.

This will help you to complete the first task.

So I'd like you to draw a diagram of the bottom of a toy vehicle and add the wheels and the axles, and then label the wheels and axles.

When you've completed that, the second part is using the words below, explain how your vehicle moves.

You might recognise some of these words: wheel, axle, rotary motion, rotate or rotates, vehicle, circle shape, round, rolls/rolling.

Pause the video now and complete Task B.

Welcome back.

Well, you've had lots of fun drawing your diagram and labelling your diagram.

So Jacob drew a diagram at the bottom of his bus.

He chose a bus.

He then labelled the wheels and axles on the diagram.

Can you see that? Axle's labelled.

The wheel is labelled.

Jacob said.

"I drew a diagram of a bus.

It has four wheels and two axles.

The axles join the left wheel to the right wheel at the front and then at the back." Well done, Jacob.

Jacob then wrote an explanation about how the axles work on his bus.

"The wheels on my vehicle are a circle shape.

They turn in a rotary motion.

The wheels at the front of the bus are joined with an axle, and the axle is a bar that joins the wheels and allows them to turn.

The back wheels are also joined with an axle.

The wheels turn in a rotary motion." Jacob, what a lovely explanation.

Well done.

I hope you've had lots of fun today completing your explanations and diagrams. We've now reached the end of today's lesson and I wonder if you can show me a thumbs up to all the learning points that we've achieved.

An axle is a rod on which wheels can rotate, and lots of vehicles use wheels and axles.

Brilliant.

And toy cars have some of the key parts of cars to make them move.

Brilliant.

Well, well done and thank you for working so hard today in today's lesson.

See you soon.
