Lesson video

Hello, everybody.

Welcome to your final lesson on this unit with me, Miss Roberts.

I am so happy that we've got to the end of this unit because I've really, really enjoyed learning all about it.

I've learned lots and I hope you have too.

In today's lesson, we're going to be learning about what it means to live sustainably.

And this is Lenny the lion's favourite topic, cause it's all about recycling and looking after our planet together.

So, I'd like to have him by my screen and he listens to all of my star words and helps with my learning.

So if you want to get your favourite teddy, you can do so.

You'll also need a pencil or a pen, a ruler, and a notebook.

So pause the video and go and get the things you need now.

Okay.

So in today's lesson, we are going to do the following.

First of all, we'll do our star words.

Then we'll think about what it means to live sustainably.

Then I'm going to talk to you about fossil fuels.

And then after that, we'll think about our own human habits.

So what sorts of things we do in our day to day lives that either help or is destroying the planet.

Then at the end, I've got a task for you.

So I think we're ready to get started.

♪ Star words ♪ ♪ Star words ♪ ♪ Star words ♪ Well done.

Okay.

Raw, your turn.

Synthetic, your turn.

Material, your turn.

Gosh, you know these so well now because we've done them in all units.

Recycling, your turn.

Recyclable, your turn.

Well done.

And biodegradable, can you say bio de gradable biodegradable, your turn.

Well done.

That's a long word.

So if the material breaks down easily out in the environment, we could say it is, biodegradable well done.

Okay.

So let's think what does living sustainably mean? So to live sustainably, sustainably means for us to live in a way that means humans will have enough materials, which they can use to help them live in the future.

To do this, we have to use less raw materials that will run out if we are not careful, as well as making sure that we do not fill up too much of the earth with rubbish.

Last week, we talked about where we send the rubbish and then it fills up, where do we send it? Landfills, well done.

So you can see on the screen, the earth and then some thinking to be done.

And then on the right is an image of the rainforest that's been cut down.

So that's a raw material that we're using lots and lots and lots of, and we're using it to read at a rate or to speed, that means that one day we will run out and then we'll be left with no rain left.

There's lots of other examples like that, such as oil.

And we're going to look at some more later in this lesson.

So this is what it means to be living sustainably.

It's about thinking about how you live in order to protect our environment and not be wasteful.

If we're using lots of plastic, this is a really, really damaging way to live for our environment.

So if I buy a new plastic bottle every single day, then that's going to be hundreds of bottles in a year.

Whereas if I reuse mine like this one, then I don't have to buy a new one.

And it means that I'm not filling up either the landfills or sometimes they even end up in the sea.

Last lesson, we looked at why that's damaging.

Why is that damaging? Who is affected? Well done, living things because their environment is then filled with rubbish, when it shouldn't be.

That's why it's important to recycle.

Now we look to recycling last lesson.

So in order to live sustainably, recycling is a really easy thing that we can do.

And it's really helpful way to live sustainably because it's using things we've already got that then can be turned into new materials and new objects rather than using new raw materials.

So clothes, plastic bottles, and other objects like cones can also be used from recycled materials.

That's why it's really important for us to recycle.

What were the two things we also save? We also save money and we also save energy.

Well done.

So, let's see how well you are listening about living sustainably.

What does living sustainably mean? I'd like you to fill in the blanks.

And question two, what do we have to do to live sustainably? I want you to pause the video, write out the whole sentence and then fill in the blanks now.

Well done.

Pause the video if you need more time, because I'm going to go through the answers.

So, question one, living sustainably means living in a way that humans will have enough materials to carry on living in the future.

Question two, we have to use less raw materials and avoid filling up the earth with rubbish.

Well done.

I hope you managed to get some of those.

Give yourself a tick if you got them correct.

If you got them wrong, that's okay.

You can just edit your answers and make sure that you've got the correct ones written down now.

So, I said that I was going to talk you through some particular resources that we are using a lot of that will eventually run out, if we keep using them at such a high level that we are at the moment.

The particular materials that we're using are fossil fuels.

There are three main fossil fuels that we need to use less of.

This is coal, this is oil, and this is gas.

Can you say the three fossil fuels on the screen? What's the first one? Coal, well done.

What's the second one? Oil, well done.

And? Gas.

Well done.

Now, fossil fuels are very useful.

They're often used to make electricity.

They also are used to make cars and buses move, and planes and trucks that can transport food and other materials all over the world.

So to live sustainably means to use less fossil fuels.

What do they often use to make? If you plug your phone into the socket, what can you get out of it? Electricity, well done.

So I'm not denying team.

That's a really useful thing that we have, but we can't sustain it.

So we need to use less fossil fuels.

We need to use less fossil fuels.

The other way that we can live sustainably is avoid getting a buildup of too much rubbish.

We should either recycle things we are finished with or make sure it's biodegradable.

Oh, what's that word? Biodegradable.

Can you say it one more time to your screen? Well done.

This means that it will naturally rot away if it's left alone and it will become part of the earth.

This is a good thing because it will turn into earth and not take up space like plastic would, if left alone.

So recycling and also using biodegradable materials are another two ways that you can live sustainably.

Can you tell you on the screen, what are the other two ways that you can live sustainably? Well done? You can recycle and you can use biodegradable materials.

Well done.

Let's have a think, how well were you listening to living sustainably.

Question one.

What are the names of the three fossil fuels that I told you about? Question two.

What are three things we can do to use less fossil fuels? So I'd like to pause the video and fill in the blanks now.

I've given you the first letter of each word so that it will give you a clue.

Write them down into your notebook, or you can read them out loud to your screen.

Okay.

Pause the video if you need more time.

I'm going to go through the answers.

So, the three fossil fuels were coal, oil and gas.

The things we can do to use less fossil fuels is, use less electricity, use cars and planes less often and try and eat food that was grown nearby.

Well done, team.

I'm sure you had a really good go at those and use your scientific brains to have a really good think.

If you've got some of them wrong, that's okay.

I'd like you to write on the correct answers in your notebook now.

Okay.

So now that we've learned about how to live sustainably, it's not always as easy as that because living sustainably means changing how you live or can do if you don't live very sustainably already.

And that means changing human habits.

Now, different people have different habits.

How we live can be very different to one another.

Some people live a very sustainable way and others less so.

For instance, some people drive to work with one person in one car, which is not a very sustainable way to travel.

However, some people cycle to work.

That doesn't use any electricity or gas, and that is a very sustainable way to live.

I enjoy recycling and try to minimise the waste that I use.

Even this year in January, I tried to go a whole month without creating any waste other than materials that I could recycle.

This was quite difficult because I had to change my habits.

And there were certain things that I couldn't buy, even though I wanted to.

And this is why living sustainably can be difficult because people need to live in a certain way, but it has to balance with living sustainably.

I'm going to talk you through some examples.

This is Cindy and she likes to buy fruit that is brought to the UK by plane.

She uses plastic cutlery and then throws it straight away into the bin.

She also drives her car into work, even though it's only a 15 minute walk.

Do you think Cindy lives sustainably or unsustainably? Does she live a sustainable life or an unsustainable life? What do you think? Well done.

Her lifestyle is unsustainable.

We mean unsustainably.

We mean unsustainable because if she did this every day, and if everybody lived like Cindy, then we are going to run out of resources and the planet is going to be damaged and full of rubbish.

Let's have another look at a different example.

This is Sam.

Now, Sam buys most of his food from the local farmer.

He only uses metal cutlery that he's kept all of his life and he rides his bike if he goes into town.

Do you think Sam lives sustainably or unsustainably? Does he live a sustainable life or an unsustainable life? Can you tell your screen? What do you think? Well done.

He lives a very sustainable life.

Buying food locally, using metal cutlery and riding his bike rather than taking the car is a very sustainable way to live.

Can you tell your screen, why is that a sustainable way to live? What is he not using? Well done.

He's not using fossil fuels.

Good job, team.

I'm going to give you a rainbow cheer, which goes like this, because you're working so hard.

There's been a lot of thinking this lesson and I can sometimes even hear your brain's working.

So, well done, everyone.

Okay.

I have a task for you.

Let's take a look.

Which type of cutlery is best to use if we want to live sustainably? I'm going to show you some examples and then I want you to decide.

Do you think plastic cutlery is the best to use, if we want to live sustainably? It's strong and cheap to make, but plastic is not biodegradable and plastic is made from oil.

Hmm.

Does that sound sustainable or unsustainable? Keep that in your mind.

Or do you think wooden cutlery is the best to use, if we want to live sustainably? It wears out quite quickly, wood is biodegradable and wood has to be used to make wooden cutlery and wood is a raw material.

Hmm.

Tricky.

Isn't it? Is that sustainable or unsustainable? Let's take a look to our final example.

Do you think metal is the best type of cutlery to use, if we want to live sustainably? It lasts a very long time.

Metal is not biodegradable, but it is easy to recycle.

And it's made from metal, which is usually iron, which is a raw material.

Hmm.

So, which do you think? I want you to have a think and write down which type of cutlery you think would be the best to live sustainably.

Pause the video, and write down your answer now.

Okay.

I wonder which one you chose.

I think I would have chosen the metal country.

Like I talked to you about with my spoon.

It lasts a really long time.

So although wood is biodegradable because it doesn't last very long, I would still have to use lots and lots of different knives and forks.

Whereas if I use metal, I can just use one knife, fork and spoon for a really long time, just like we saw with Sam, in our example.

Okay.

To finish off this lesson, I have a think question for you.

Do you think you can live sustainably and drive a car? Hmm.

Because driving a car uses fossil fuels.

Doesn't it, team? But, some people really need a car.

Maybe you live in the countryside.

Maybe you live a really long way away from the shops.

So do you think you can live sustainably and drive a car? There's no right or wrong answer here team.

So I'd like you to have a think about what you think for the answer is.

And then I'd like to ask either your grownup at home, or maybe someone at school or maybe a friend, and you can have a scientific conversation about this.

Well done, everyone.

You've worked so hard on this unit.

I'm so impressed and so proud of everything that you've learned.

You've done so, so brilliantly with your learning.

What's an incredible scientist you are.

I wonder what you're going to learn next.

And I can't wait to see how you grow as a scientist in the years to come.

Bye, everybody.
