Hi everyone.

It's Ms. Panta here, I hope that you are well.

I'm really excited and glad you've decided to join me on today's science lesson.

So we're going to be learning all about different rocks and their everyday uses.

Have you got your thinking cap on? 'Cause we've got lots of learning to do today.

Let's get started.

So the outcome for our lesson today is I can list some everyday uses of rocks and explain how the physical properties of rocks makes them suitable for different jobs.

So we're going to think about different types of rocks today and how they can be used in our everyday lives.

So we're going to talk through some key words now.

Now we're going to practise saying them.

I'm going to say the word and I would like you to repeat it back to me.

My turn, rock, your turn.

Super.

My turn, suitability, your turn.

Great job.

My turn, appearance, your turn.

Fantastic job.

My turn, physical properties, your turn.

Amazing.

So we're going to talk through some key words now.

Now some of these words you will know what they mean and some of you might not be so sure, but don't worry 'cause we're going to cover them all in today's lesson.

So rock is a solid material that occurs naturally on earth.

Suitability is the fact of being acceptable or right for something or someone.

The appearance of an object is the way something looks.

And physical properties are features which can be observed from the way an object looks or feels or can be measured.

So some of these words you may have looked at in your rocks units already or you may have seen some of these words in some of your other lessons.

So our lesson today is split up into two sections.

So we're first going to think about the suitability of rocks and then we're going to move on to the everyday uses of rocks.

So let's get started with the first parts of today's lesson.

So the first thing I would like you to do is compare the objects in these images.

What material do they have in common? So pause the video here and I want you to talk with your talk partner.

Compare the objects and the images.

What material do they have in common? Have a think.

Fantastic job everybody.

Well done.

They all have been made from different types of rocks.

So that was something the same between all four of these images.

The statue and walls of the house have been made from hard rocks like marble and granite.

The chalk sticks and chess piece have been made out of softer rocks like chalk and soapstone.

So all of these images here are all made of rock, but different types of rock.

Super job, everybody, well done.

So Andeep here, "I wonder why we use rock to make so many things? "Is it something to do with its suitability?" What do you think? What do you think about what Andeep has said? So he's wondering why we use rock to make so many things.

Is it something to do with its suitability? What do you think, do you agree with Andeep? Great job everybody.

So when we make things, we want them to last a long time and be hard wearing.

So we've got this example of a stone road here.

Sometimes we want to be able to change the shape of things or leave a mark as decoration.

And we can see an example here of a religious tablet.

Suitability means being suitable for the job or being the perfect fit or the right fit.

Not all rocks are suitable for the same purpose.

Why do you think that chalk would not be suitable for making a chopping board? So have a think really carefully.

If you are making a delicious dinner and you're using a chopping board, why would chalk not be a suitable material or suitable rock for making a chopping board? Have a think with your talk partner.

Super job everyone.

A chopping board made from chalk would be impermeable and too soft.

So it would not be a suitable rock to make a chopping board.

How do we decide which rocks are most suitable for different jobs? How do you think we decide? Maybe join your partner with another partner and in a small group you can have a discussion about how do you think we decide which rocks are the most suitable? What ideas can you come up with? Have a think in small groups.

Super job everybody.

I hope you had a really great time having a discussion in your small groups.

Andeep and Alex think about how the appearance and physical properties of rocks make them suitable for different jobs.

Andeep says, "I didn't realise how useful rocks are "for things other than building.

"They have many different physical properties like strength, "permeability, and absorbency." And Alex says, "Don't forget the appearance "of a rock can be important when choosing "which one is suitable." My mom's bracelet contains rocks that sparkle.

Well done everyone for completing the first part of the lesson.

So we're going to do a question just to check our understanding.

True or false, it doesn't matter which rock you choose to make an object as they all look the same and have the same physical properties? Do you think that's true or false? Have a little think.

Super work, everybody, the answer is false.

We now need to think a little bit about why it's false.

So is the answer A, the type of rock makes it suitable for some objects but not others or B, objects are not made from rock as it is not suitable for making things? So which answer do you think is correct, A or B? Super job, everyone.

The answer is A.

So the type of rock makes it suitable for some objects but not others.

Super job everybody, well done.

You're doing such a great job so far in today's lesson.

So let's move on.

Which of these are made using rocks? So we've got ceramic pots, which you may see in the garden.

Toothpaste, which you use every day to brush your teeth.

And a fountain.

So talk with your talk partner.

Which of these are made using rocks? Think really carefully.

Off you go.

Super job, everybody.

The actual answer is they all contain rocks.

So we're going to learn a little bit about this now.

So limestone has physical properties suitable for making pots that would be strong for cooking.

We've got some examples of ceramic pots here.

Toothpaste often contains tiny amounts of chalk.

It is suitable because it can gently remove stains on the surface of your teeth.

So although toothpaste can seem very smooth when you squeeze it out of the tube, it actually contains tiny amounts of chalk.

And the appearance of marble is attractive.

Marble is also impermeable so it is suitable for a fountain.

So we've got three different objects here and things that we can see and use.

And actually they're all made out of parts of rock, but they all look very different and they have all different properties.

Super job everybody, well done.

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

Look at the appearance of these rocks, which would be most suitable to make a colourful necklace from? Do you think it'd be A hornfeld, B slate, or C obsidian? Have a look really closely.

If you need to, pause the video, come up really close to the screen.

Which of these rocks do you think would be suitable for a colourful necklace? Have a think.

Super job, everybody.

The answer is C.

So we can see with obsidian, yeah, it's got a slightly different colour.

It's got some patterns within the rock.

Super job everybody.

Let's do another question to check our learning.

June needs to choose a rock that is suitable for an outdoor skateboard ramp.

Which of these physical properties would the rock need to have? A, soft, crumbly and permeable? B, rough, hard and impermeable? Or C, tough, smooth and impermeable? So have a think about those keywords and have a think about what you need to create and think about which of the physical properties the rock would need to have.

Have a think.

Super job everybody.

Well done.

The answer is C.

So because it's for a skateboard ramp, we know it'd need to be a really tough rock.

Smooth so you'd be able to ride it, and also impermeable as well.

Well done everybody.

So let's move on to the first task for today.

So there's a few different parts to today's first task.

So if you need to, pause the video and jot down some notes just so you ensure that you follow all the instructions correctly.

So step one, use research or the cards on the next slide to find out more about objects made from rock.

And I'm going to read through the information on the next slide a little bit later.

Then I would like you to find one of these objects in real life or a different one made from rock and then draw or take a photograph of it and name the rock it is made from.

Once you've done that, I would then like you on a separate piece of paper to describe the appearance and physical properties of the rock in as much detail as you can and stick this over the picture to make a flap that can be lifted.

Then the final part I would like you to share with a partner to see if they can guess what the object is and which rock it is made from.

They can check if they are right by lifting the flap of paper.

So you're playing a little bit of an investigation game here.

So you're creating a little game all about different rocks and hopefully you can then play this game with your partner.

So I'm going to read through some examples here and you can use these cards or you can do your own research.

So for example, chalkboard.

A chalkboard is a reusable writing surface.

They were originally made of smooth hard sheets of black or dark grey slate stone.

We've got cat litter.

Cat litter is an absorbent material for pets to use as a toilet.

It also traps any bad smells.

It can be made from limestone, which is permeable and can be broken down into small pieces.

And lastly, a bird bath.

A bird bath is a place birds can bathe and have a drink.

It can be made from an impermeable stone like granites to keep the water from leaking.

So if you would like to, you can use these examples or you can do your own research.

If you need to, go back a slide and go through the instructions again.

I hope you have a great time playing this game with your partner.

Off you go.

Super job everyone.

I hope you had a great time playing this game.

So be a rock detective.

Can a partner guess what the object is and which rock is it made from? So for example, you may have chosen, this as your bottom sheet, a cat litter which contains limestone and the top part here is a little bit of a clue.

So this would be the top flap sheet.

I am grey and dusty.

I'm good at soaking up liquids as I am permeable.

I am quite a soft rock so I can be broken down into smaller pieces or granules.

I am used to mask strong smells that pet cats produce.

What am I? So maybe you use this as an example and and hopefully your partner was able to guess.

What rocks did you do? Did your partner guess them correctly? Well done for having a fantastic go at this task everybody, I'm so impressed with your learning.

So we are now going to move on to the second part of our lesson today.

So we're now going to think about the everyday uses of rocks.

So people have been using rocks for millions of years to build things that are useful to our lives and Stonehenge is an example of that.

Stonehenge was built in 2,500 BC using bluestone and sarsen sandstone to make a stone circle where people gathered.

Now maybe some of you have visited Stonehenge.

That's somewhere definitely I would like to visit, but I haven't had a chance to yet.

Have you been before? Hundreds of years ago we didn't have human made materials like plastic and concrete to make things with.

Rock was a material that was readily available in the natural world.

So people used it to make things.

Do you know what these objects were used for? Pause the video here and maybe if you need to come a little bit closer to the screen, have a look really carefully.

What do you think these objects were used for? Have a go we're gonna talk through the answers really soon.

Well done everyone for predicting what these objects were used for.

So the first image here is heavy balls were fired from canons to protect castles.

The second image here is wheat was ground on millstones to make flour.

And heavy stone anchors were used to stop a boat from floating away.

So we can see here that rock was used for lots of different things.

Fantastic work everybody, well done.

Let's do a quick check of our learning.

True or false, humans have only used rocks in recent years to build things that are useful to our lives? True or false? What do you think? Super job, everybody.

The answer is false.

Now let's have a little think about why.

Do you think A, because humans have used rock for millions of years because it is a natural material, or B, humans have been making rock for millions of years.

Which one to we think is correct? Wow everybody, well done.

The answer is A, humans have used rock for millions of years because it is a natural materials, it's been on earth.

That's why it was able to be used for so many different things.

The stone age was a period of time in history that began about 2.

6 million years ago.

So a long, long time ago.

During the stone age, humans only had natural materials like rock and wood to build and make things from.

They had access to different types of rocks from the land depending on where they lived.

They chose the most suitable rock depending on its physical properties and appearance for different jobs.

Stone Age humans chose hard rocks like flint and hammer stone to make a weapons such as spears and arrowheads to hunt with.

And we've got a picture here of some of the hunting weapons.

They made tools such as this hammer and wheels to put on carts from rocks like sandstone.

So we can see here that Stone Age humans used rocks for lots of different things to help them with their everyday lives.

Lucas says, "I wonder how they chose which rock to use.

"Do you know?" Can you tell me how do you think they chose which rock to use? Super job, everybody, well done.

They chose the rock for the suitability of its physical properties.

Well done everybody.

Stone Age humans also chose suitable rocks for their appearance to make attractive and ornamental objects to look at and wear.

So you've got an example here of some limestone jewellery.

They used a softer sparkly rock like limestone, as it was easier to shape to make beads for necklaces.

They used softer, colourful permeable rocks like chalk to make marks and paintings on cave walls.

So we can see here, there's lots of different examples of how the stone age humans use different rocks.

Now let's do a quick check of our learning.

Which of these stone objects would be used to grind wheat to make flour? Would it be A ornament, B pestle and mortar, or C chalk? Have a think about the learning we've done today, which is the correct answer? Amazing work, everybody well done, a pestle and mortar.

So this was used to grind wheat to make flour.

Super job, everyone.

So let's move on to the next task.

You have travelled back in time to the stone age, using the most suitable rock, you need to make a bowl or cup, a weapon to kill a mammoth, an axe to chop down trees, a wheel for a cart to carry wood in, a gift for your friends, paint to make a mural on your cave wall.

So your task is to write the name of the most suitable rock for each object and explain why you chose it.

Now Lucas is giving us a little bit of help here.

He says, think about the physical properties and appearance of the rocks you choose.

Try to choose a different type of rock for each object and use secondary research to help you.

So you may want to use the internet or you may want to read some books a little bit more about rocks so you have a better understanding and can use and name different types of rocks for these objects.

Now if you need to, pause the video here, jot down those different items and think about which rock would be most suitable.

Have a go and we'll talk through some examples really soon.

Off you go.

Wow, everybody, I'm so impressed with your work on this task.

I know it was a little bit tricky because there was quite a few different objects, but you've all worked incredibly hard.

So let's go through some examples.

So you may have written flint to make a spear, as its sharp.

You may have written marble to make a cup as it's permeable or sandstone as it's easy to carve for the wheel.

Hammerstone as it is strong for the axe, jasper to make a deer shaped toy as it's golden like a deer or soapstone for painting as it's soft and leaves a mark on the wall.

So these are just a few examples.

Did you get these examples? Maybe you've got some different ones.

I would like you to now compare your work with your partner.

Did you think of the similar types of rocks or did you think of different ones? Have a few moments now to compare your work with your partner.

Off you go.

Well done everybody for comparing your work with your partner and with these tasks.

It's fantastic because you may not have the same examples as your partner, but both of your examples may still be correct.

So well done for having a good go at this task everybody.

So we've now come to the end of our lesson today.

So let's do a summary of our learning.

The appearance and physical properties of rocks make them suitable for different jobs and humans have used rocks for millions of years to make things that are useful to our lives.

So we've learned in our lesson today that there are lots of different types of rocks and they can be used for lots of different things, even toothpaste that we use every single day.

Well done for all of your work today, everybody.

You've worked incredibly hard and used all your knowledge of rocks to help you with the tasks today.

I hope you have a great rest of the day and I'm sure I'll see you in the next lesson very soon.

Bye-bye.
