Lesson video

Hello, everyone.

How are you today?

I hope you're doing really, really well.

And I hope you're looking forward to this lesson where we are going to be exploring a new subject today.

But first of all, let me tell you who I am.

My name is Ms. Ef-sal, and I'm going to be a science teacher today.

I'm feeling so very excited about this because today we are getting into our new subject about rocks.

A lesson is called an Introduction to Rocks.

And it comes from the unit of work, Rocks and Soils.

So I am so curious to find out what do you know about rocks.

Are you interested in rocks?

I really hope so.

I hope you are.

And don't worry, even if you don't know much about rocks, we are gonna be getting right into it.

There is so much to discover and learn and love about rocks.

Are you ready to begin?

The outcome for today's lesson is I can explain that rock occurs naturally and can be used for different purposes.

We have a number of keywords in today's lesson, so we're going to go through them one at a time.

First of all, we'll just go through and say the words.

We'll say them, my turn your turn.

And then we'll go through the meaning of each of these words.

They'll be coming up in our lesson today, so it's gonna be really helpful for us to find out more about these keywords.

So let's begin.

Material.

Rock.

Earth.

Natural.

Quarry.

I love hearing those keywords out loud: material, rock, earth, natural and quarry.

Turn to someone next to you and tell them, "Have you heard of any of these words before?

" Which ones have you heard of?

Thanks for sharing.

Let's find out what these keywords mean.

A material is what we use to make things from.

Rock is a solid material that occurs naturally in Earth.

Earth is the planet we live on.

What an amazing, beautiful, incredible planet we live on.

A natural object or material has not been made or changed by humans.

And a quarry, this is the place where rock is dug out of the ground.

So these are our keywords.

Let's look out for them.

Let's listen out for them.

Let's think carefully about them.

They'll be coming up in our lesson today.

Our lesson is called Introduction to Rocks, and it consists of two learning cycles.

First of all, rock is a natural material.

And next, using rock.

I hope these sound interesting to you.

Let's begin by exploring, rock isn't natural material.

A material is what we use to make things from.

Remember that?

That was one of our keywords.

Material.

Let's say that again one more time.

Material.

Fantastic, glad to hear that loud and clear.

There are lots of different types of materials.

For example, there is wood, metal, and plastic.

What might we make from these materials?

Pause here, turns someone nearby and share with them, what can we make from wood?

What can we make from metal?

And what can we make from plastic?

Thanks for sharing.

I wonder what ideas you came up with.

Perhaps you talked about wood, maybe you said that you could make a chair out of wood.

Metal, perhaps you talked about making cutlery, like a spoon or a knife or a fork.

And plastic, maybe you talked about making a bowl or a cup from plastic.

Thanks for sharing your ideas.

Now I would like you to take a look at these objects that you might find in a classroom.

So many objects there, so colorful, so varied.

My question for you is what materials are they made from?

Now you can do this actually in two ways.

You could just take a look at the picture on screen and the objects you can see in that classroom.

Or if you are in a classroom right now, you might like to take a walk around your classroom and have a look at some of the objects around you and think about what materials they're made from.

So in either case, I'd like you to do that now.

Find some objects in the classroom, either on the screen or in the classroom that you are in, and decide what materials these objects are made from.

Pause here while you do this.

Thanks for having a go at that.

I am so curious.

What materials did you find?

Let's have a look.

So here we can see there is a glass screen.

The signs are made out of paper.

The carpet is made from wool.

There are cotton cushions, plastic containers, and a wood trolley.

So many different materials.

Well done for spotting these.

And maybe you found some others too.

Let's have a check for understanding.

True or false, a material is an object that we make out of something.

Pause here and decide.

Is this true or false?

Well done if you selected false.

And now I'd like you to justify your answer to give a reason for your answer.

Is it A, a material is what we use to make objects; or B, a material is only used for making clothes?

Pause here while you decide.

Well done if you selected statement A.

Indeed, a material is what we use to make objects.

Some materials are natural.

So we've got two keywords in that sentence.

I like that.

Natural materials are found on Earth, another keyword, in nature and have not been made by people.

Wool is natural.

It comes from sheep.

Rubber is natural, it comes from trees.

Cotton is natural.

It comes from a cotton plant.

Can you think of any other materials found in nature?

Pause here and share with someone.

What can you think of?

Well done if you came up with some more materials found in nature.

You might have seen rocks in different places in nature.

Perhaps that's one of the things that you came up with.

We can see rocks in mountains.

We can see pebbles on a beach and rocks in caves.

Can you think of any other places you might have seen rocks?

Maybe in real life or perhaps in pictures?

Thanks for sharing the other places that you might have seen rocks.

Rock is a natural material.

This means it hasn't been made or changed by humans if it is a natural material.

And we can see on our screen here some pieces of rock, a boulder, so a huge piece of rock, and a rock formation.

How wonderful.

Rocks can be many shapes and sizes, as we can see here.

Where do you think rocks come from in nature?

Pause here and share with someone.

What do you think?

Thanks for sharing your ideas.

Let's find out a little bit more about where rocks come from.

Rock is a solid part of Earth's surface or crust.

Some rocks are under the ground, and we need to dig them out using machines.

The place we dig rocks out of the ground is called a quarry.

It's another one of our keywords.

Should we say that one more time?

Quarry.

Good to hear that word.

And look at this immense quarry that we can see on a screen.

Let's have a check for understanding.

Which of these are natural materials?

A, water; B, sand; C, plastic.

Pause here while you decide which of are natural materials.

Well done if you selected answers A and B.

Indeed, water and sand are both natural materials.

Plastic is not a natural material.

It is human-made.

Let's have another check for understanding, true or false.

Rock is a natural material.

Pause here and decide.

Is this true or false?

Well done if you selected true.

And now I'd like you to justify your answer to give a reason for your answer.

Did your answer true because, A, rock is a natural material as we buy rocks from a builder's merchant?

Or B, rock is a natural material as we dig rocks from the ground?

Pause here while you decide.

Well done if you selected statement B.

Indeed, rock isn't natural material, as we dig rocks from the ground.

And now it's time for your first task.

I would like you to research how we get rocks from Earth.

You might use books or the internet to help you.

Use drawings or photographs to create a comic strip to show each stage of quarrying the natural rock from the ground, and include these words.

Some of these are our keywords: rock, natural, quarry, dig, ground and material.

So pause here while you have a go at this task, create a comic strip, maybe even a poster, whatever you like, some creative way of showing each stage of quarrying the natural rock from the ground.

Enjoy your task.

I'll see you when you're finished.

It's great to be back with you.

How did you get on with that task?

Let's take a look.

I love this comic strip of research, how we get rocks from Earth.

So first we find a suitable quarry which contains natural rock.

We use diggers and sometimes dynamite to quarry the rock from the ground.

The natural rock is then loaded into huge trucks.

This natural material is taken to a factory or stone mason to be used.

What a great job.

Well done, everyone.

Sofia is wondering if all rocks are natural materials.

"I thought some rocks are made by humans.

My dad works in a factory that makes concrete and tarmac, and these are kinds of rocks, aren't they?

" And we can see an image there of some tarmac on the road and some concrete, perhaps in the side of a building.

Talk to a partner about what you think about Sofia's question.

Pause it while you do this, and I'll see you after you've had your discussion.

It's great to be back with you.

So how did you get on with that talk to your partner?

So here was Sofia thinking about rocks that they were made by humans.

She says, "My dad works in a factory that makes concrete and tarmac.

And these are kinds of rocks, aren't they?

" Here's Jun's answer, "Tarmac, concrete and brick are a human-made material.

They're not a natural material like rock.

So they need to be manufactured in a factory.

" Perhaps you had an answer like this.

And now we're onto our next learning cycle, using rock.

People often use natural materials to make things.

Wool, that's a natural material.

And you might use it to make a jumper, which is human-made.

People dye the wall from sheep to knit into jumpers.

Rubber, it's a natural material.

And it could get made into a hot water bottle, that's human-made.

People heat up the rubber and mix it with other materials to make a hot water bottle.

Oh my goodness, hot waterfall tools are one of my favorite things.

They're just so cozy.

Rock is a natural material that is used all around us.

Look at these pictures and describe what rock is being used for.

Here's the first picture.

Pause here and share with someone.

What is the rock being used for here?

Well done if you said castle walls.

Next, what is a rock being used for in this picture?

Pause here and share with someone.

Well done if you said the roof.

And here's another image.

What's a rock being used for in this picture?

Yes, it's a statue.

And finally, what is the rock being used for this picture?

Yes, you spotted it.

The children are using chalk, which is a rock.

Rock is dug from a quarry and shaped by humans into useful objects.

Can you think of any objects made from rock?

Pause here and share with someone.

Thanks for sharing.

The arch has been made from lots of pieces of rock built on top of each other.

Such an incredible construction, the arch.

The ornament has been carved from a piece of rock to make a face.

Such intricate carving.

And these gemstones have been polished and cut to make them into jewelry.

And I'd like to show you my gemstone.

This is a rock that has been put into some metal to create a pendant that I can wear it around my neck every single day.

These materials look like rock, but they are not found naturally: tarmac, concrete, and brick.

They're not rock because these materials are made by humans.

Tarmac, concrete and brick are human-made materials that are often used to make brick houses, tarmac roads, concrete pavements.

Can you think of any other places these materials are used?

Pause here and chat with someone.

Thanks for sharing.

I wonder what you came up with.

Perhaps you've noticed that sometimes steps are made using concrete, or even sometimes some statues.

Let's have a check for understanding.

Which of these are natural materials?

A, tarmac; B, concrete; or C, rock.

Pause here while you decide.

Well done if you selected C, rock.

This is a natural material.

Tarmac and concrete are human-made materials.

Let's have another check for understanding.

Which of these objects are usually made from rock?

A, statue; B, shed; C, steps.

Pause here while you decide.

Well done if you selected A, statue and C, steps.

The shed is usually made from wood.

And another check for understanding.

Which of these statements about rock are correct?

A, all rock is natural and comes from the ground.

B, some rock is natural and some is human made.

C, materials made by humans such as concrete and brick are not rock.

Pause here while you decide which of these statements about rock are correct.

Well done if you selected A and C.

These statements are correct.

All rock is natural and comes from the ground.

And materials made by humans such as concrete and brick are not rock.

And now it's time for your next task.

I would like you to go on a rock hunt around your school and local area.

Look for rocks being used for different purposes.

Try to record what you observe as natural rock or human-made rock.

You can take photographs of rocks using a camera or draw some of the places you see different rocks.

And you could create a record like this which shows how is the material being used and was it natural rock or human-made material.

So pause here while you have a go at this task going on a rock hunt.

Sounds cool.

I'll see you when you're finished.

Great to be back with you.

How did you get on with your rock hunt around your school or local area?

Your table may have some of these examples in it.

Some things like tarmac and brick look like they're made from rock, but they're human-made materials.

So let's take a look at this, so we've got the roof, which is natural rock that's made of a rock called slate.

Brick wall, that's a human made material.

Gravestone, that's been carved from a piece of rock, natural rock.

And a road is a human-made material.

It's made from tarmac.

Great job, everyone, going on your rock hunt.

In our lesson today, Introduction to Rocks, we have covered the following: a material is a substance from which something is made; rocks are a material which occurs naturally; materials such as concrete, tarmac and brick are made by humans and a not rock; we use different rocks for different purposes.

Well done, everyone, for joining in with this lesson, our introduction to rocks.

It was so great to get into this subject.

I really enjoyed this lesson, finding out all about different kinds of rocks and their uses and materials which are not quite rock, but are human made, which we might think are rock.

And I hope you've enjoyed this lesson too.

I would like to encourage you as you are out and about to take a look around you and to see what can you see around you that has been made from rock.

And also take a look at what are some human-made materials in your local environment.

Keep up the rock hunting, and I look forward to seeing you at another lesson soon.

Bye for now.
