Lesson video

Hi there everyone, it's so nice to see you and welcome to your science lesson.

You are having a science lesson with me, Miss Emms and I'm going to be your science teacher for this week which is really exciting.

We are starting a whole new unit of learning and we're going to be learning all about space.

So today it's our first lesson all about space and our key question, so the thing that we're thinking about today is what is space? You might've heard people talking about space.

Maybe you've learned about space in your school that you normally go to but we're going to have a think in more detail today about what is space.

So after that we're going to have a little introduction to space.

We're going to do some reading together about space and you're going to answer some retrieval questions and then we're going to have a think about some of the objects that you might find in space and some of the objects that you would not find in space.

And then we're going to move on to thinking how we find out about space.

How do we know about it? How do we find out information about space? And finally, I know that you all really enjoyed completing these quizzes because you're so good at getting really, really good marks in them.

You're going to have a go at your end of lesson quiz.

So make sure you're listening carefully as we move on through the lesson, okay? In this lesson, you're going to need three things.

As usual you're going to need an exercise book or some paper.

So you'll either have a book or you might have a piece of paper and either is fine.

You're going to need a pen or a pencil and you're going to need your brain switched on and ready to go.

Sometimes I like to go like this when I'm trying to get my brain to work really, really hard.

Do you want to do that as well so you're ready for your lesson.

Amazing.

If you need to pause the video to go and get your exercise book, paper, or your pencil, you've got your brain, you don't need to get that then pause the video now to go and get those things so you're ready.

Pause now.

Welcome back everybody, we are ready to go.

So let's have a quick recap before we start our new learning.

What I'd like you to do is I would like you to on your piece of paper, you're going to write down exactly what I've got on my screen.

So you're going to write down these key words.

Light, dark, light source, shadow, and reflection.

Don't do it yet, just listen to the instruction.

So you're going to write down light, dark, light source, shadow, and reflection.

And then on the other side of your piece of paper you're going to write down these definitions but they're all jumbled up.

The absence of light, something that makes light, a type of energy that travels in waves from a light source, when lights bounces off an object and forms when an object blocks a source of light.

But the thing is light is not the absence of light.

It's not that the line goes across here.

They are all jumbled up.

So using your knowledge, your amazing knowledge from our previous learning, I would like you to match, to draw lines to match the definition to the key words.

Okay? I'd like you to have a go at doing that now.

So pause the video and have a go at completing that task.

Off you go.

Okay everybody, how did you find that? Were you able to do most of them? Amazing, well done.

Let's have a look at our answers.

So if we start at the top, we know that light is a type of energy that travels in waves from a light source.

We also know that it travels in straight or curvy lines.

Tell your screen, you're so right.

Always in straight lines.

Well done.

We know that dark is the absence of light.

So dark is when there is no light.

A light source is something that makes light.

Can you tell your screen an example of a light source? Tell your screen one light source.

Well done.

I heard some children saying the sun, some children saying lamps, some children remembered that fireflies produced lights as well.

I heard some children saying torches, amazing.

Anything that produces light.

Is a window a light source? Yes or no? You're right.

It's not, it lets through lights from a light source but it itself is not the light source.

Moving on to a shadow.

So we know that a shadow forms when an object blocks a source of light.

An opaque object or a transparent object.

Tell your screen.

Amazing, an opaque object that blocks most light rays, therefore it creates a shadow.

And finally reflection.

We know that reflection is when light bounces off an object.

I'm just going to give you a minute now to tick or fix any of those answers if you need to.

And don't worry if you made any mistakes, remember that helps our brains to grow.

Pause the video now if you need to make any changes or tick your answers.

Amazing, well done.

What a great way to make sure that we've gone back into our previous learning and now we're ready for our new learning.

And as a starter activity I wonder you might not know any, which is absolutely fine because we haven't learned about this yet and we're going to learn about this over the course of these lessons.

But if you do, can you make a list on your sheet of paper all the planets you already know exist in our solar system.

So any planets that you already know exist in our solar system.

Can you pause the video and write down any that you already know? Off you go.

Great job everybody.

That's just to start us thinking about the knowledge that we already have about this learning and we're going to learn much more about this as our lessons go on.

So keep that bit of paper so that at the end of our learning, you can see how much you have learned.

Okay and now let's think about space.

This lesson is going to help us answer the question what is space? And here you can see a picture of some space.

And it's an amazing picture.

Hopefully it gets you excited for our learning today.

So here we're going to read the following text together.

I'm going to read it.

And what I'd like you to do is get your pointer finger ready? Have you got it? And you're going to place it underneath.

Can you join in with the reading if you can, I'm going to go quite slowly.

Starting here.

Space is everything in the universe beyond the top of the Earth's atmosphere.

I'm going to say that again, say it with me if you can.

Space is everything in the universe beyond the top of the Earth's atmosphere.

It is where everything, all of the planets, the sun, the moon, stars, galaxies, and other objects are found.

I'm going to read that bit again.

It is where everything, all of the planets, the sun, the moon, stars, galaxies and other objects are found.

Outer space.

Can you say that to your screen? Great job.

Begins about a hundred kilometres above the Earth where the shell of air around our planet disappears.

So if we imagine our planet Earth, around our planet there is a shell of air but about a hundred kilometres away from our Earth that shell of air disappears and that's where outer space begins.

That's where outer space begins.

So with no air to scatter sunlight and produce a blue sky, so we can see well today it's actually not very sunny but this week has been really sunny.

And normally we can, sometimes we can see a blue sky and that's because air scatter sunlight.

But without that space appears as a dark blanket dotted with stars, just like in this picture here, a dark, it looks like a dark blanket and it's dotted with stars and that's because there's no air to scatter sunlight.

Now it's time that we've had a little bit of learning already, we're going to pause and I'm going to ask you to answer some retrieval questions, to answer some recap questions from what we just learned and you can choose how you answer these.

You could say the answer to your screen.

You could write an answer down or you could draw a picture of the answer.

Three options.

Number one, I'm going to read them all and then you're going to do them by yourself.

So listen to all three questions.

Number one, what is space? Can you remember how we describe what space is? Number two, what are some things you can find in space? What can you find in space? And number three, where does outer space begin? Don't worry if you don't remember the answer to all of them, just have a go.

I'm sure you can remember something from our learning so far.

Pause the video and either say, write or draw the answer to these questions or a combination of those three methods of answering them.

Pause now.

Wonderful.

Well done everybody.

Great effort.

Really impressed.

Let's have a look at what you could have written.

So space is everything in the universe beyond the top of the Earth's atmosphere.

Everything in the universe beyond the top of the Earth's atmosphere.

What can you find in space? You might've had some of these.

You might've had all of them.

Maybe you could add the ones you didn't get.

You can find planets, the sun, the moon, stars, galaxies, and other objects.

And we're going to think over the course of this unit about the other objects that you might be able to find.

And where does outer space begin? It begins about a hundred kilometres above the earth where the shell of air, remember we said, there's a shell of air above our earth.

And when that disappears and when that ends that's where outer space begins.

I'm going to pause now, if you want to tick or fix any of your answers, you can pause the video now, before we move on.

Okay, we are ready to move on.

Let's think about space.

We're going to read the following text together and this is quite a fun part to read.

So I'm going to read it and you are going to point to the words on your screen.

In space no one can hear you scream.

If you screamed now, maybe you shouldn't scream 'cause there might be people doing some work in your home.

But if you did scream, everyone will be able to hear you.

Maybe the people next door, maybe your neighbours would be able to hear you, but in space, nobody can hear you scream.

This is because there is no air in space.

It's a vacuum.

Space is usually seen as being completely empty but this is not true.

The gaps between the stars and planets are filled with huge amounts of gas and dust.

So there is no air in space and that means that no one would be able to hear you if you screamed in space.

Exploring space is difficult because it contains no air and it's so big.

Show me an action.

It's so big that even the fastest spaceships can only explore a tiny part of it.

Now spaceships carrying astronauts are designed to keep good air inside them and to protect them from extreme temperatures.

Did you know it takes three days of travelling to reach the moon roughly.

Some people have done it quicker, some people have done it slower, but it takes about three days, three full days of travelling to reach the moon and that helps us realise how far away the moon is from our Earth.

We've come to our next task now, and this is a thinking task where you're going to make some predictions.

I want you to draw or write the names of the following things on your piece of paper.

So either you can draw the sun, plants, buildings, the moon, aliens, and other children or you could write the names, the sun, plants, buildings, the moon, aliens, other children, or maybe like I've done you can do both.

Pause the video now and have a go at drawing or writing the names of those six objects.

Those six things.

Off you go.

Well done everybody.

Great job.

So now what I want you to do is I would like you to have a think about which objects you could find, you think you could find in space.

And you're going to put a tick next to the objects that you could find in space.

And you're going to put a cross next to the objects that you could not find in space.

Have a go, for each one think hmm, do I think that this would be in space? Tick for yes, cross for no.

Pause the video and have a go at completing that task? Great job everybody, let's have a look at the answers.

So the sun we know from our learning already that the sun, you will find the sun in space.

You won't find any plants.

There is no air in space.

You won't find any plants.

You won't find any buildings.

You will find the moon.

You won't find aliens.

I wonder if some of you maybe put a tick for this one.

There is no evidence of any other life, so any alien life in space that's something that sometimes we think from reading stories.

There's no evidence of that so that should be a cross and you wouldn't find other children like on planet earth.

You wouldn't find other children in space.

Pause the video if you need to tick or fix your answers.

Okay let's move on.

Can you think of any other objects that you might find in space? We're not going to correct this.

Again I'm going to ask you to keep it and you can see if you were right as we go on through our learning, through these lessons.

Can you draw or write down any other objects that you think that someone might find in space? You can draw a box like mine or you can just draw them underneath your last question.

Off you go, pause the video now.

Amazing.

Well done everybody.

Keep that safe.

So coming on to think about our last question now.

How do we find out about space? How do we find out? How do we gain information about space? I wonder if you've ever heard of an astronaut.

Can you nod if you've heard of an astronaut? Can you tell me what's the job, what do you do if you are an astronaut? Can you tell your screen and astronaut? Well done.

An astronaut explores, goes into space to find things out about space.

There are two main ways that scientists and astronauts find out information about space.

One of them is using a telescope, okay? A telescope, something that you use to see into space so that we can find information about space.

Can you say the word telescope? Amazing.

Well done.

The other is a space probe.

Can you say space probe? And that's something that's situated in space so it can help us gather information about space.

We gain most of our information about the items in space from different kinds of telescopes.

Some are called space telescopes put in outer space for a better view.

So either you have a telescope that you use from our planet or scientists can place space telescopes in outer space for a better view of space.

Also space probes explore planets, comets, and other space objects that are not too far.

So telescopes and space probes.

Can you say those two things that help us find out about space? Telescopes, space probes.

Your turn.

Amazing.

I want you as a quick recap to tell your screen how do telescopes and space probes help scientists learn more about space? Pause the video and tell your screen.

Well done everybody.

And now it's going to be time after I've said goodbye to you all to do your end of lesson quiz.

So today was our introduction lesson to get us thinking about space before we move on to learning even more about it in our next lesson.

Well done today for all of your really awesome work.

I'm super impressed with everybody.

I think that we deserve, and I've been doing this in English, a high 10 for great work.

So you rub your hands together, get them ready.

And we're going to go three, two, one.

Amazing.

And if you'd like to share your work or any pictures then you can ask your parent or carer, must do that.

Ask them to share your work on Twitter @OakNational with #LearnWithOak.

Okay I'm already really looking forward to seeing you next time for our next lesson all about space.

Bye.
