Lesson video

In progress...


Hello, everybody.

Welcome to another lesson on materials with me, Miss Roberts.

I'm so excited to be back here with you today, and I know that Lenny the lion is too.

So he always sits by my screen and he always listens to my star words as I say them.

And he listens to all of the learning that I do to my screen.

'Cause I know it can be a little bit strange telling your screen all the information rather than a real teacher, but Lenny the lion can listen.

So if you want to get your favourite teddy and your other resources, here's what you're going to need; A pencil or a pen, a ruler, and a notebook, just something to write on.

Pause the video and go and get the things you need now.

Okay, pause the video if you need more time.

A quick recap again, just about those three ways that you can turn a raw material into a synthetic material.

What's the first way with that fire? You can add, heat well done, or you can mix, well done, or you can add chemicals, well done.

Those are the three ways to turn a raw material, into a synthetic material that we've learned about.

Well done, everyone.

I can see that you're ready for learning today.

In today's lesson, we're going to do our Star words then we'll think about what is recycling then we'll think why do we recycle? Then we'll look at materials that we can recycle and then I've got a task for you.

So let's do our Star words, are you ready? Star words Well done, you guys are ready today.

The first word is raw, with the action, your turn, raw, your turn.

Well done.

The next word, remember with all always with the actions, synthetic, your turn.

Synthetic, your turn.

Well done.

Material, your turn.

Material, your turn.

Well done.

Recycling, your turn.

Recycling, your turn.

The next word is recyclable, your turn.

Recyclable, your turn.

Well done.

So if material is recyclable, then it means it is able to be recycled.

What does recyclable mean team? Can you tell your screen? Well done.

And last word, pollution, your turn.

Pollution, your turn.

Well done.

Okay, so let's have a think, what is recycling? I'm sure you've heard the term before.

And you might have even seen a green bin, either at your school or in your home.

But what is recycling? What actually happens? I wonder, do you recognise any of the symbols on your screen? Some of you do, do you know where you've seen them before? Can you have a think? Well done, you might have seen them on packaging.

And if, a recycling symbol is on a piece of packaging, then it means that that can be recycled.

What does this symbol mean? If it's on a piece of packaging, it means it can be recycled.

So, what's the similarity between all three images? What's one thing that's similar about all three of them? Can you tell your screen? Well done.

They all have a circular arrow of some sort.

So the first one is a bin with a circular arrow, the second one has three circular arrows, creating a circle, and the third one, is arrows pointing in towards each other, creating a circle or a triangular connection.

And that shows that there is a cycle and that's why we call it recycle, because it's a cycle of connecting materials and using them again.

So we call it, recycling.

So when we're recycling, it is a process of collecting and re-using materials to make new synthetic materials.

This is important for a number of reasons.

One reason for this, is that raw materials come from the ground and will eventually be used up.

Raw materials that come from living things can be replaced, but it uses up a lot of energy and money to grow and collect these materials.

As a result, it's better to re-use old materials, to save energy and money.

On the screen, you can see three examples of packaged up material that is ready to be recycled.

The one at the top is cardboard, The one on the left is plastic, and those green ones are green glass bottles.

They can be recycled into new materials.

The images on the right, are of recycled materials and objects.

At the top, there are some clothes, that have been recycled.

On the left, are some bottles of shampoo and conditioner.

And those bottles, are made out of recycled plastic.

As is, the cone on the right hand side.

This means that we don't have to find and use any new raw materials.

We can just re-use materials that we already have.

Okay, let's see how well you were listening.

Recycling is a process of something and something, materials to make new synthetic materials.

Question two.

Why do we want to avoid using raw materials too much? Pause the video and write the answers in your notebook now.

Pause the video, if you need more time and you've not finished, 'cause I'm going to go through the answers.

So, recycling is a process of collecting and re-using materials to make new synthetic materials.

Why do we want to avoid using raw materials too much? Well, we can save energy and money.

What can we save? Energy and money, well done.

Give yourself a pat on the back, if you did those correctly.

Really impressive team.

If you got them wrong, that's okay, I would like you to now rewrite the answers on top so that you've got them correctly on your notebook.

So now that we know what recycling is, why do we do it? I've talked already about re-using materials, so that we don't have to find and resource raw materials from the ground or from living things.

So I'm going to talk you through four main reasons, why we recycle.

We want to avoid destroying natural habitats.

For instance, when we cut up wood, this can leave many living creatures without a home, maybe from forests or woods or even rainforests.

We want to avoid damaging the environment.

In the image there, that is a spillage from an oil tanker, and this can really damage the birds and the sea life surrounding it.

The final problem, is waste.

When we throw things in the bin and do not recycle them, these are often taken to big areas of land called landfills.

Can you say landfills? Landfills.

What are the two words they're making the word landfill, land and, fill, well done.

Because we literally are filling the land.

And I'm sure that you can then understand that we are going to run out of space, If we keep trying to fill the land, and put all of our rubbish in landfill, we will eventually run out of space.

So we want to reduce what we send to landfill.

And we can do this by, recycling.

Many landfills, are getting fill up, from the amount of rubbish that's been thrown away.

So we may run out of places to put our rubbish.

This rubbish can also cause pollution in the environment, making it harder for many living things to survive.

So, let's see if you can remember those four things, that I talked about as to why recycling is important.

Why are landfills not an effective way, to dispose of rubbish? Why is it not a good thing to always use new raw materials to make things we need? I like to have a think about those questions.

If you need to, you can go back and listen to the video or you can have a go, first of all, write down the answers in your notebook now.

Okay, pause the video if you need more time, 'cause I'm going to go through the answers.

Question one, landfills are not effective, because we're going to run out of space to put all our rubbish.

We're going to literally, fill the land.

It's not a good thing to always use new raw materials, because it can damage the environment and can destroy habitats.

For instance, if we're cutting down lots of trees in the rainforest, then birds and monkeys and all sorts of organisms are going to lose where they live.

And that can be really damaging, because where are they going to go? So, let's think about materials we can recycle, so that we can avoid damaging our environment.

We can recycle; plastic, paper, glass, and metal.

These are four materials that we can recycle quite easily.

And I've got some examples here.

Here, I've got a plastic bottle.

Now plastic bottles aren't really damaging for the environment, because they don't biodegrade.

That just means that they don't break down.

So if I put it in the garden, it's going to be there for a really long time.

Whereas if I put a banana peel, for instance, that would break down and it wouldn't last forever.

It's really important then, that we recycle all of our plastic, such as bottles, cutlery, and any plastic plates that we might use.

It's also really easy to put them in the recycling bin.

There we go, it's in my bin now.

Glass is another one.

Now this is a glass cup that I used to drink water out of, but, once I'm finished with it or it may be, if it breaks, I can put it in the recycling.

And that means that instead of this, going in the bin and going to a landfill, it can be re-used and turned into something else.

I've also got some cardboard.

This is something that a package arrived in today.

I could put it in the bin, but I could also put it in the recycling.

And that means that it can be converted into something else rather than going to landfill.

So I'm going to put it in my recycling bin.

There it is, is in.

The last metal, example I've got for you here is a spoon.

So sometimes you have crockery, and you have cutlery.

Now cutlery tends to be made out of metal.

If I wanted to get rid of it, maybe it's broken or damaged, or I just need to get rid of it because I get a new set.

It would be very wasteful to put it in the bin, because then like I said, where does it go? It goes to landfill.

And if we keep filling, the landfills up, we're going to run out of space.

So instead, I could recycle this spoon and put it in the recycling, so that it can then get turned into something else.

So, let's have a think about our task.

I've got some interesting things for you to think about.

Which reason for recycling, do you think is the most important and why? So this is for you to decide as a scientist, what you think is the most important reason.

There isn't really a correct answer for this, because all the reasons are very important, but I really want you to consider what you think, because as a scientist, we have to make decisions like that.

So do you think, that the most important to reason is because we're going to run out of raw materials? Do you think it's because we're using up space? Or do you think it's because we're destroying habitats? I want to have a think, and note down your answer in your notebook now.

Well done.

Okay, and now I've got some words for you on the screen.

These are going to help you, fill in the blanks on the next screen.

So let's just read them through together, so that you know what they are.

My turn, your turn run out of space well done raw run out and natural habitats.

Natural habitats just mean, somewhere that animals or organisms live.

Like I've said before, monkeys in the rainforest, lose their habitat if we cut down the trees.

There are lots of other examples that I could give you.

So, using those words on the screen before, I want you to fill in the blanks.

I want you to pause the video, read through the screen and see if you can use those words, to fill in the blanks.

You could also download this worksheet to help you, if you want to.

Well done everyone.

So let's have a look.

Even if you've not written them down, you can tell your screen what you think those blanks are.

It is important to recycle, because if we only used, what do you think? Raw materials, then we will eventually, run out, well done.

Another reason is that the landfills we send our rubbish to, will eventually, what will they do? They will run out of space.

Well done team.

By polluting natural areas, we are also destroying, natural habitats, well done.

Even if you've got some of those incorrect that's okay, I'd like you to edit your work, and write on the correct answers now.

Well done everyone.

I've been really impressed with your learning this lesson.

I'm going to give you, an awesome chair because you are awesome.

So I want you to have a think about this question.

Why is it a good thing to recycle paper? Why is it's a good thing to recycle paper? I wonder, is paper something that you use a lot? I wonder if it is.

I want you to have a really good think about that question and talk to somebody that you know, maybe it's your teacher, maybe it's somebody at home and have a scientific conversation with them about what you think and then ask them, why they think it's a good idea to recycle paper.

I'll see if your next lesson and I can't wait to do some more learning on materials.

Lenny is really, really impressed with how hard you've worked today.

Bye everybody.

See you next time.
