Hello, and welcome to today's lesson all about materials and their uses.

My name is Mrs. Mehrin and I am really looking forward to learning with you today.

Welcome to today's lesson from the unit "Uses of everyday materials." Your learning outcome today is, I can explain why different objects are made from different materials depending on their use.

Now I know that learning can sometimes be a little bit challenging, but that's okay because we are going to learn together and we are going to work really hard to learn lots of fabulous new things.

Let's begin.

Here are your keywords for today.

We're going to do my turn, your turn.

My turn, object.

Your turn.

My turn, compare.

Your turn.

My turn, material.

Your turn.

My turn, describe.

Your turn.

My turn, property.

Your turn.

Fantastic.

Well done.

Now our learning today is split into two sections.

Let's begin with the first one, common materials.

Now the world is full of different objects.

An object is something that you can touch, but something that is not usually a living thing.

So it's something that you can touch, but it's not usually something that's a living thing.

Now let's have a look at these three pictures here.

Do you know what these objects are? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

So here we have a bottle, a hairbrush, and a pair of shoes.

Now do you know what these objects are? Again, I'll give you five seconds to think about your answer.

Off you go.

Fantastic thinking.

Well done.

Here we have a ball and a bath toy.

So we've got a rubber duck here.

Now we can compare these objects and Laura says, when we compare things, we say what is the same and what is different.

Now I want you to think really hard.

What do you think is the same and what do you think is different about these objects here? So I'll give you five seconds to think about your answer, but if you need longer, you can pause the video here.

Off you go.

Fabulous! Well done.

So you might have said that both of these objects are yellow.

Both of them have a little bit of black on them.

They're both made of plastic.

You might have said that they're waterproof.

So those are all of the things that are the same.

However, things that might be different, we've got some pentagon shapes there on the ball and we don't have that on the duck.

The duck, the duck has red there around its beak, but the ball does not have any red, and they are different shapes as well.

So lots of similarities and differences between them.

Now I want you to think what is different about these objects? We've got a chair, a jar, and toy building bricks.

Now I'll give you five seconds to think about your answer, but if you need a little bit longer, that's okay.

You can pause the video here and you can have a go.

Okay, off you go.

Fabulous.

Well done.

So you might have said that these objects are made from different materials.

So we have a wooden chair, we've got a glass jar, and we have plastic toy building bricks.

Now you might have also said that they all have different uses as well, and different colours.

Now we said that these objects were made from different materials.

Now a material is what an object is made from.

So for example, the jar is made from glass, the chair is made of wood, and the toy building bricks are made from plastic.

Now let's do a quick check-in of your learning so far.

So a material is A, something an object is made from, B, something that you eat, or C, something that you hear.

Again, I'll give you five seconds to think about your answer, but if you need longer, you can pause the video here.

Off you go.

Fabulous.

Well done.

The answer is, it's something an object is made from.

Now do you know what these objects are? So I'll give you some time.

I'll give you five seconds to think about your answer, but if you need longer, you can pause the video here.

Okay, off you go.

Fabulous.

Well done.

So we have got a chair, toy clowns, and picture frames.

Now do you know what material all of these are made from? I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

These objects are all made from wood.

Fantastic learning and fantastic thinking as well.

Well done.

Now here's another one.

Do you know what these objects are? I'll give you five seconds to think about your answer, but if you need longer, you can pause the video here and then you can come back once you have an answer.

Okay, off you go.

Fabulous.

Well done.

So we have a key and a padlock, a pair of tweezers, and a tin can.

Now then, do you know what material all of these objects are made from? Again, I'll give you five seconds to think about your answer.

If you need longer, you can pause the video here.

Okay, off you go.

Fantastic.

Well done.

Now these objects are all made from metal.

Brilliant learning.

Well done.

Now do you know what these objects are? Again, I'll give you five seconds to think about your answer, but if you need longer, you can pause the video here.

Off you go.

Fabulous.

Well done.

So we have a yoghurt pot, toy teddy bears, and drinking straws.

Now do you know what material these objects are made from? Again, I'll give you five seconds to think about your answer.

If you think you need a little bit longer, just pause the video here and come back once you are ready.

Okay, off you go.

Fabulous.

Well done.

These objects are made from plastic.

Now do you know what these objects are? You are getting really good at this now.

So have a really good think.

I'll give you five seconds to think about your answer, but if you need longer, you can pause the video here.

Off you go.

Fabulous job.

Well done.

We have a hand lens, a jar, and a light bulb.

Now do you know what material these are made from? Again, I'll give you five seconds to think about your answer.

If you need longer, pause the video and come back once you are ready.

Off you go.

Fabulous.

Well done.

These objects are made from glass.

Now then, do you know what these objects are? I'll give you five seconds to think about your answer, but if you need longer, you can pause the video here.

Off you go.

Fantastic! Well done.

So we have a wall, a bridge, and a chimney.

Now I want you to think really carefully about this.

Do you know what material all of these objects are made from? Again, I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

These objects are made from brick.

Now let's do a check of your learning and it says, which of these is a material? Is it A, a watering can, B, a hot water bottle, or C, a brick.

Okay, I'll give you five seconds to think about your answer, but if you need longer, you can pause the video here and come back once you are ready.

Off you go.

Fabulous.

Well done.

The answer is C, brick is a material.

Now I want you to think carefully about this.

It says, do you know what these objects are? So I'm going to give you five seconds to think about your answer, but if you need longer, you can pause the video here.

Off you go.

Fabulous.

Well done.

We have chalk sticks, a pumice stone, and a statue.

Now do you know what material they are made from? Again, I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

These objects are made from rock.

Here is another one.

Do you know what these objects are in this picture? I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

We have a reading book, tissues, and a notebook.

And do you know what material they are made from? Again, I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

These objects are made from paper.

Now here is another one for you.

Do you know what these objects are? Again, I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

We have boxes, toilet roll tubes, and pizza boxes.

Do you know what material these objects are made from? Again, I'll give you five seconds to think about your answer.

Off you go.

Well done.

We have got a rucksack, a dress, and a cushion.

Do you know what material all of these objects are made from? I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

These objects are made from fabric.

Let's do a quick check-in of your learning.

Which of these objects is made from fabric? Is it A, a drinks can, B, a T-shirt, or C, a box? I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

The answer is B, a T-shirt.

Now what you are going to do for your task is you are going to go on a materials hunt around your classroom, school, or your home, and I want you to look for objects which are made of these materials.

So wood, metal, plastic, glass, brick, rock, paper, fabric, or cardboard.

So I'd like you to pause the video here and have a go at that activity.

Off you go.

Fabulous! Well done.

So you may have found some of these objects, maybe similar things or you may have found different things.

So out of wood, you may have found a chair or building blocks.

Metal, you may have found a fork or a paperclip.

Plastic, it may have been book bag boxes or a ruler.

You may have found glass windows or glass drinks.

Drinks glasses.

You may have found a brick wall.

You may have found a garden sculpture or pebbles made from rock.

You may have found books and posters made from paper.

Jumper and curtains made from fabric.

Or a jigsaw box made from cardboard.

Fantastic work.

Well done.

Now I want you to think about what else you might have found? Maybe, you have found lots of different things.

Well done.

Now we are on to the second part of our learning today, which is describing materials.

You are doing so well.

Now Andeep and Sofia are observing a toy duck.

They use their senses to describe the material it is made from.

Andeep says, this material feels soft and bendy.

It is opaque, which means it is not see-through.

And Sofia says, what do we call the words that we use to describe materials? Can you remember? I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

So the describing words we use for a material are called its properties.

Laura says, observe this bottle.

What material do you think it is made of? Can you think of any words to describe the properties of this material? So I'll give you five seconds to think about your answer, but if you need longer, you can pause the video here.

Off you go.

Fabulous.

Well done.

So let's have a go at this question.

It says, the words we use to describe a material are called its A, problems, B products, or C properties.

I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

The answer is C, properties.

Now what material are these objects made from? And what do you observe about the properties of these materials? So I'll give you some time now to think about the answers.

You may need to pause the video here and then come back once you have an answer to the questions.

Off you go.

Fabulous.

Well done.

So we've got a plastic toy elephant and a plasticine elephant.

And Izzy says, the plasticine elephant changes shape when I touch it, but the plastic elephant does not.

Now some materials are hard and some are soft.

Can you think of any other hard or soft materials? Again, I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

Now I want you to think about these questions here.

It says, what material are these objects made from? And what do you observe about the properties of these materials? So we have a rubber band and a wooden spoon.

So again, you may need to pause the video here so that you can have a really good look and really observe closely and then come back once you are ready.

Off you go.

Fabulous.

Well done.

So Izzy says, the rubber band can be stretched.

The wooden spoon is stiff and cannot be stretched.

So some materials are stretchy or bendy and some are stiff.

Can you think of any other stretchy or stiff materials? Again, I'll give you five seconds to think about your answer, but if you need longer, you can pause the video here.

Off you go.

Fabulous.

Well done.

So let's have a look at this question here.

It says, what material are these objects made from? And what do you observe about the properties of these materials? So we have a plastic sponge and a fabric umbrella.

Okay, again, I'd like you to pause the video here.

Have a really good look, really observe closely, and then come back once you have some answers.

Off you go.

Fabulous.

Well done.

So Izzy says, an umbrella is made from waterproof fabric that doesn't let water through.

A sponge is not waterproof and lets lots of water through.

Now some materials are waterproof and some are not.

Can you think of any other materials that are waterproof or not waterproof? Again, I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

So let's do a quick check of your learning.

It says, which of these objects is made from a waterproof material? Is it A, a pair of rubber gloves, B, a pair of socks, or C, a pair of jeans.

Okay, I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

So a pair of rubber gloves is made from a waterproof material.

Now what material are these objects made from? And what do you observe about the properties of these materials? So we have a metal pan scourer and a fabric tie.

Okay, I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

So Izzy says, the scourer feels very rough.

And the tie is not rough.

It feels very smooth.

So some materials are rough and some are smooth.

Can you think of any other rough or smooth materials? Again, I'll give you five seconds to think about your answer.

Fabulous.

Well done.

What material are these objects made from? And what do you observe about the properties of these materials? So you have tin foil and a wool scarf.

Okay, I'm going to give you five seconds to think about your answer, but if you need longer, you can pause the video here.

Off you go.

Fabulous.

Well done.

So Izzy says, the tin foil is very shiny.

The scarf is not shiny.

We call this material dull.

Some materials are shiny and some are dull.

Can you think of any other shiny or dull materials? I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

Now what material are these objects made from? And what do you observe about the properties of these materials? So you have a cardboard box and a glass window.

Okay, I'm going to give you five seconds to think about your answer, but if you need longer, you can pause the video here.

Off you go.

Fabulous.

Well done.

So Izzy says, I cannot see through the cardboard box, so it is opaque.

The window is made of glass, and I can see clearly through it, so it's transparent.

So some materials are transparent and some are opaque.

Can you think of any other transparent or opaque materials? Again, I'll give you five seconds to think about your answer.

Fabulous.

Well done.

Let's do a quick check of your learning.

It says, which of these objects is made from an opaque material? Is it A, a hand lens, B, a pair of sunglasses, or C, a tin? Okay, I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

The answer is C, a tin.

Fantastic.

Well done.

Now different objects are made from different materials, depending on what they are used for.

So jumpers are used to keep us warm and to keep us covered.

Now this jumper is made from wool.

Why do you think wool might be a good material to use for making a jumper? So I'll give you five seconds to think about your answer, but if you need longer, you can pause the video here.

Off you go.

Fantastic.

Well done.

Now chairs are made for us to sit on, and this chair is made from wood.

Now why do you think wood might be a good material to use for making a chair? Again, I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

And scissors are used to cut things into smaller pieces, and these scissors are made from metal.

Now why do you think metal might be a good material to use for making scissors? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

Now true or false.

Objects are made from different materials.

I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

The answer is true.

And I think this because is it A, objects have different uses, or B, objects are different sizes? Okay, I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

The answer is because objects have different uses.

Now here is the second task today.

It says, look at the objects you found in Task A and talk to a partner to answer Sam's question.

It says, what is this object used for? And what properties does it need to do this? So I'd like you to pause the video here and have a go at doing Task B.

Off you go.

Fabulous.

Well done.

So Andeep says, a window is made to let light in and for us to look out of it, so it needs to be smooth and transparent.

And Sofia says, my ruler is made of plastic.

It needs to be hard and stiff, so it does not change shape or bend when I measure things.

Now what else did you find? And did you say the same as Andeep and Sofia or did you think of different properties? I'll give you some time now for you to pause the video here and think about those questions.

Off you go.

Fabulous.

Well done.

Now here is the summary of your learning today.

It says, a material is what an object is made from.

Some common materials are wood, metal, plastic, glass, brick, rock, paper, fabric, and cardboard.

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

Objects are made from different materials, depending on their use.

Okay, you have worked so hard today.

I am so proud of you.

And there's been absolutely loads to learn! But you have been fantastic and you've used your critical thinking and you have worked really hard.

Well done.
