Hello, everyone, this is Mr. James, and I hope you are looking forward to doing some science today.

Are you feeling curious? Great, let's begin.

Our lesson today is from the unit Everyday Materials and today's lesson is called Material Properties.

And your learning outcome is this.

By the end of the lesson, can you describe simple properties of everyday materials? I'm sure that you'll be able to do that.

Let's go.

We have some keywords that will crop up as we go through the lesson, so let's practise saying them.

My turn, your turn.

Here it goes.

Material.

Well done.

Describe.

Properties.

Observe.

Feel.

So our lesson today, we're gonna start out by exploring the properties of materials and then we're going to compare and group properties of materials.

Right, here it goes.

What's this? Do you recognise the material that this is made from? It's a frying pan.

It's made from metal, but can you think of any words that would describe metal? Pause the video now.

I wonder what words you thought of.

Perhaps they're the same words that Lucas thought of.

He said, "This metal is silver, shiny, hard, and smooth." Do you recognise the material that these bottles are made from? That's right, it's plastic.

They're made from a hard plastic.

Can you think of any words that would describe this plastic? Pause the video now and see which words you can come up with between you.

Well done.

So Laura came up with these words.

She said, "This plastic is smooth and stiff." Different materials can be described in different ways.

Now, Andeep is looking at a window.

"This window is made of wood and glass," he says.

Sam says, "The wood is not see-through and the glass is see-through." Izzy and Alex are looking at materials.

"All materials are the same, so we use the same words to describe them," says Alex.

"We can use different words to describe different materials," thinks Izzy.

Who do you agree with? Pause the video and have a little chat about that now.

Did you agree with Izzy? Izzy is right.

There are lots of different materials like plastic, fabric, and wood, so we can use lots of different words to describe them.

When we talk about materials, we use different describing words.

These describing words are known as the properties of a material.

Let's look at cardboard.

Lucas says, "The properties of this cardboard are stiff and dull.

The describing words we use for a material are called it's, what do you think? Is it, A, its objects, B, its properties, or C, its parts? Yes, it's the properties of a material.

Jun is observing this jumper.

Which words would you use to describe the properties of the material the jumper is made from? The words we use to describe a material are its properties.

Pause the video and see which words you can come up with between yourselves.

Great, let's look at another material.

Lucas is observing this ruler.

Which words would he use to describe the properties of the material that the ruler is made from? Pause the video and have a think.

So, what about another material? This time a watering can.

Which of the children, Alex or Sofia, which of these children is describing the properties of the material that the watering can is made from? Let's hear what they say.

Alex says, "This watering can is made from plastic.

The plastic is hard and shiny." Sofia says, "The watering can has a handle and a spout and is used for watering plants." So, which of the children is describing the properties of the material the watering can is made from? Give me a wave for Alex.

Give me a wave for Sofia.

Now, which of those two do you think is right? Wave if you think it's Alex.

Wave if you think it's Sofia.

Yes, it's Alex who's describing the properties of the material that the watering can is made from.

Sofia is describing the different parts of the watering can and what it's used for, which is a little bit different.

Jun and Lucas use some of their senses to help them to describe the properties of materials.

Jun could use his eyes to observe the jumper and Lucas could use his hands to feel the ruler.

So Jun used sight and Lucas used touch.

Which other sensors can we use when we explore the properties of a material? Have a talk about that now.

Pause the video.

Good, well done.

Now I'd like you to think about this toy building brick.

Which senses will Andeep need to use to find out about its properties? What do you think? Well, the brick is hard and makes a clicking sound when you put two bricks together.

It's smooth and stiff.

So the senses that Andeep uses to come up with this description, he uses his sense of sight, he uses his sense of touch, and he uses his sense of hearing to explore the building brick.

Aisha uses her senses to describe the properties of the material that an object is made from.

Which object could she be describing? This is what she says.

"This object is made from a material that is smooth, hard, and see-through." Right, we're gonna do hands up now.

I'll read out the three it could be.

Wave your hands in the air when I get to the one that you think is right.

Is it the sheet of paper, is it the perfume bottle, or is it the chair? A material that is smooth, hard, and see-through.

Yes, it's the perfume bottle.

Sofia describes the properties of the material that an object is made from.

Which object is she describing? Here we go, same thing again.

This object is made from a material that is a bit rough, it's bendy, and it is not see-through.

You ready to wave your hands when I get to the right one? Here we go.

Could she be describing a tin, a coat, or a bottle? What did you think, I wonder? Yes, it was the coat that is a bit rough, bendy, and not see-through.

So now I've got a task for you to work on.

I'd like you to create a feely board.

You can each create one or create them with a partner.

Use different materials, attach the different materials to the feely boards.

Discuss the materials and the words that you could use to describe their properties.

Here's the example for you to get started with.

So we have card or cardboard on the back and some different materials stuck onto it.

Okay, it's your turn now to have a go at making one.

There are lots of different materials that you could use.

You could use foil or rubber, sandpaper, bubble wrap, fabric, or plastic, or perhaps something else that you can find.

Then I'd like you to describe the properties of the different materials that you've chosen, like foil and bubble wrap.

So Jun describes the foil and this is what he says.

"The foil is bendy and shiny, it is not see-through." Sofia describes the bubble wrap.

"The bubble wrap is see-through and stretchy." Laura describes rubber and Sam describes fabric.

This is what Laura says about the rubber.

She says, "The rubber is stretchy and bendy, it is not see-through." Sam says about the fabric, "The fabric is soft, I think it is not waterproof." Lucas describes sandpaper.

He says, "The sandpaper is rough, it cannot be stretched." Alex describes plastic.

He says, "The plastic is smooth and dull, but I can see through it a bit." When you've completed your feely boards, it will be time to move on to the second part of today's lesson, comparing and grouping properties of materials.

Izzy is observing objects made of different materials.

She decides to put them into groups.

Here they are, the classroom objects that Izzy decides to put into groups.

I'll compare each material first by asking what is the same and what is different about their properties.

Izzy decides to compare and group these materials into rough and smooth.

She observes and she feels each object before deciding which group to put them into.

So in the rough group, she has sorted sandpaper, a pinecone, and a scouring pad like you use to clean dishes in the sink.

And in the smooth group, Izzy has put a bottle, some silk fabric, and a spoon.

Now Izzy decides she's going to compare and group the materials into hard and soft.

She knows that soft materials change shape easily when she touches them, so this time she ends up with only one of the materials in the soft group, and that is, yes, silk.

In the hard group, there's the bottle, the pinecone, sandpaper, the scouring pad, and the spoon.

And Izzy's done it again, she's observed and she's looked at each object again and she's grouped them.

How do you think she's grouped the objects this time? Pause the video and have a quick talk about that.

Yes, this time she's thought about whether the objects, the materials are see-through or whether they're not see-through.

So the see-through is only the bottle and the not see-through includes the silk, the pinecone, the sandpaper, the scouring pad, and the spoon.

Some objects are made of more than one material and they may have different properties.

The paintbrushes, for instance, they have soft bristles at the top and a hard handle at the bottom, so you could say that they go in the middle of this group because they are both soft and hard.

And in the soft group we have the silk and in the hard group we have the sandpaper and the spoon.

Laura is grouping materials into hard and soft.

She explores a toy building brick made of plastic.

"The sides of the brick are soft, so I will put it into the soft group," she decides.

Do you agree? Take a moment to think about that.

Pause the video now.

Now, the sides of this toy building brick are not soft, but they are smooth.

If a material is soft, this means it's not stiff or hard to touch and it will move or bend when you touch it.

A toy building brick does not do this, so it will go into the hard group.

Take a moment to think about these materials that we talked about when we were doing task A.

I want you to see if you can group these six materials into rough or smooth, stiff or bendy, shiny or dull.

Pause the video now and talk about this with a partner.

How did you get on? Here we've sorted the materials into rough and smooth.

So we have the sandpaper and the bubble wrap, they're rough, and the rubber, the rubber gloves, and the thin plastic, which are smooth.

And if we sort them into stiff and bendy, we have the sandpaper, stiff, and bendy, the fabric, the thin plastic, and the rubber.

Shiny and dull.

The foil is shiny.

The sandpaper, the fabric, and the rubber gloves are dull.

Well, can you think of any other ways of grouping the properties of materials? Have a talk about this now.

Pause the video.

I'm sure you came up with some interesting ways of grouping materials.

Well, it's now time for us to think about all that we've learned in our lesson today.

We've learned that different materials can be described in different ways.

The describing words that we use for a material are called its properties.

We use our senses to investigate and describe the properties of materials.

Materials can be compared and grouped by their properties.

How did you get on? I hope that you are now feeling confident to describe the properties of some simple materials.

I'm sure you are.

Well, well done.

You've done well today and I shall see you next time.

Bye.
