Lesson video

Hi, everyone, welcome to today's science lesson.

I'm Ms. Harris, what's your name? Lovely to meet you.

Should we start today's lesson off with a virtual high five.

Great, so hold your hand up like this, and you go, just put a high five in the middle, ready? Three, two, one, go.

Great, now we are going to be answering this question.

How can I describe an object? So, so far we have learned what materials are and what objects are.

And we're going to look at how we can describe them today.

But don't worry, we're going to be recapping what a material is, and what an object is today.

So also we are going to be doing these things.

We're going to be looking at what an object is, identifying different materials, identifying the properties of materials, identifying properties of objects, and then we've got our end of lesson quiz.

Now remember that every lesson I've got a different background.

And at the end of the lesson, I want you to tell me what material is used in my background.

Do you think you can do that? Great, now you will need an exercise book, or a piece of paper, a pencil, a coloured pen or pencil, and most importantly, you will need your brain, so you can do lots of wonderful learning.

If you don't have any of these things, you can pause the video and go and get them now.

Okay, well done.

Now these are our Star Words.

They're the really important words we're going to be saying in this lesson, you ready? So we're going to do my turn, then your turn.

So you're going to say it out loud to your screen so someone can hear you.

Okay, You ready? Waterproof.

Smooth.

Opaque, so opaque means it does not let any light through, opaque.

Transparent, so transparent means it lets all the light through.

So like my glass is transparent.

Stretchy.

Absorbent.

Rough, your turn.

Smooth, your turn.

Good, now we're going to do them.

I'll whisper, you're ready? Waterproof.

Smooth.

Stretchy.

Now we're going to shout, absorbent.

Transparent.

Opaque.

Great job, now let's recap what a scientists is.

Scientist is a person who studies the world around us, including things living and non-living.

So remember that living things are animals and plants, and we are living things, humans.

But remember that non-living things are things like books, or pots and pans, or a table.

So in our unit, this unit that we're doing now, Materials, we are studying non-living things.

So like a cup is not a living thing.

So first, let's recap.

What is an object? And objects, can you follow with your finger, is something that is made out of materials.

Each material can be used to make lots of different things.

Okay, I'm going to read it now.

So you sit comfortably.

An object is something that is made out of materials.

Each material can be used to make lots of different things.

So remember that everything is made up of material, but an object is something that is made from a material.

So my glass, my cup is made from glass.

So let's look at some types of materials.

So can you tell me what these objects are made from? What is the material? The material is? Glass, well done! The material here is? Wood, well done.

The material shown here is P? Plastic, and the material used here is? Metal, well done.

Now we are going to look at some properties of materials.

Properties are what we would use to describe each material.

So the properties are how we would describe a material.

So first, we could describe a material's properties as being soft or hard.

Soft or hard.

Can you think of a material which is soft? So a fabric is soft.

So my clothes are soft.

They're made out of fabrics.

But my wooden box, that you've seen before, is made from wood, and it's hard.

Then we have got absorbent and waterproof.

If something is absorbent, it soaks up the liquid into itself.

So a sponge, if I put the sponge in some water, it would soak up the liquid.

Whereas for waterproof, if I had a jacket and it started raining, and it stopped me from getting wet, it would be waterproof.

It doesn't soak up the water.

It keeps the water out.

So absorbent soaks up the water, and waterproof, keeps the water out.

Then we have got transparent and opaque.

So here, let me show you, I've got two different materials, which you've seen before.

One is transparent, one is opaque.

Which one keeps all of the light out? This one, the metal, you're right.

It keeps all the light out, we can't see what's inside.

Where as the glass is transparent? We can see through the glass.

You can see Ms. Harris's face through the glass, it's transparent.

Okay.

Are you ready? It's our pause point.

Can you name all of these properties by looking at the pictures? So put your finger on the picture and tell me what the property is.

Are you ready? You have 10 seconds, I'm going to count to 10.

You ready, can you name them all? Go! Did you get them all? I counted to 10.

Did you get them all? Great, let's check.

So first we have soft, at the top here, and hard.

Soft and hard, they are opposites.

Then we've got absorbent and waterproof.

It keeps the water out.

So we've got absorbent and waterproof.

Can you do those actions? Absorbent, waterproof.

Then we've got transparent where we can see through it.

So transparent.

Can you go like this? And we've go opaque, so you can cover your face to stop the light coming in.

Opaque, transparent, opaque.

Hard.

Soft.

Absorbent.

Waterproof.

Great job at doing the actions, well done.

Now let's identify some properties of different objects.

So here are some objects and some materials, which are transparent? Can you identify some of these materials? So I've got some ice.

That's transparent, we can see through it.

Water, a plastic cup, and over the other side, we've got a glass cup, which we know is transplanted because Ms. Harris has a glass.

We've been looking at it.

So transparent, transparent, your turn.

Good, we can see through it.

Then we've got opaque.

What materials can you see here? Brick, well done, what else? Wood, rock, and what's over the other side, L, L, you might not know this one.

Leather, the belt is made of leather, and it's got a metal buckle on the side, on it.

So these objects are made out of materials, which are opaque.

So remember opaque is like this, opaque, your turn.

So it means it doesn't let the light through.

Okay, you ready for one more? How am I describing these materials? They are us S.

Soft, good, so we've got some wool up here, which is really soft.

Ms. Harris has got some wool here as well.

So let's have a look at my wool.

So my wool here is soft.

Look it's, ooh, it's so squishy and soft.

So I would describe the wool as soft.

We've then got the leather here, which is also soft.

We've got some cotton balls and some fabric, and a rubber at the top, which we can also describe as soft.

Now here are two properties, which we haven't talked about yet.

Can you think about what these might mean? So what are the properties shown him? Can you pause the video and tell your screen, and then press play when you're done.

Did you check, what were they? So we have got flexible or bendy.

Flexible or bendy, whichever word you want to say, and shiny.

Great job, so we've got flexible and shiny.

They are some new ones that we haven't heard before.

So we know that Ms. Harris's tin can is shiny, look you can see how shiny it is.

But it's not bendy.

It's not bendy.

So I am going to show you a picture of an object, and we are going to be writing down the properties off each material.

So here is an example of what you are going to do.

So here we have some cling film which you might use to wrap around your food to keep it nice and fresh.

We are going to identify the object and the material, so here.

Cling film is made from plastic.

So you can see here, I'm going to say it because I've got this little icon here, the speech bubbles, I'm going to say it.

Cling film is made from plastic.

Then in my book, I am going to write down what the plastic is like, I'm going to describe its properties.

So plastic, the material, is transparent and waterproof.

It's transparent and waterproof.

So first I'm going to say what the object is and what it's made out of.

Then I'm going to describe the material, what it's made out of.

And you can use the word map on the other side to help with your spelling of the properties.

So here is your first one.

Can you say what the object is? So what can you see in this picture? Towels, good, towels are made from cotton.

Can you say that word? Cotton, cotton is a type of fabric.

Cotton is mm and mm.

So you're going to write down two words, two properties to describe cotton.

Pause the video and do that now.

Well done, so let's check.

So cotton, you could have said, is soft.

You may have said as well, that it's opaque.

Or you could have said it's absorbent because we use a towel to dry ourselves, once we've had a shower or bath.

And it keeps us nice and dry once we've rubbed it on our skin, it gets all the water off.

Okay, here's the next one.

Windows are made from what? Glass, well done.

Now you're going to write down two properties to describe glass.

Don't forget to use the word map on the other side.

So glass is mm and mm.

Write that down in your book, of you go.

Well done, so glass, I might have said, is hard and opaque.

Sorry, transparent.

Sorry, it's not opaque.

Glass is hard and transparent because we can see through it.

You may have described it as waterproof as well because when it's raining and our window is closed, it doesn't let the water come in, does it? Great job.

Now it's time for our observation that we've been doing every week.

How many different objects can you find? And can you identify their materials? So first, pick up an object.

Then you're going to say, what material is it made from.

Then you're going to describe its properties.

So let's recap.

First, pick up a object.

So I might pick up, mm? I'm going to pick, what shall Ms. Harris pick up? I'm going to pick up my straw.

So I've got my straw.

What is it made from, is the second one that I'm going to say? So I might say, hmm? My straw is made from metal.

Then I'm going to describe it, mm.

The metal is hard, and, mm, it's opaque because I can't see through it because it's really colourful.

So pick up the object.

My straw is made from metal, and it's hard and opaque.

Can you have a go at doing that with some objects that you can find around your house? Great, are you ready for the drum roll? Ready, pick up your hands.

Ready, drum roll, three seconds.

You can do it on your lap or you do it on the table, ready? Three, two, one.

What's it time for? Our End of Lesson Quiz, whoo-hoo.

And you can see me jumping up with a little heart.

It's time for the End of Lesson Quiz.

How many questions do you think are in our quiz? Three, well done.

Three questions are in our quiz.

Can you get them all right? I'm sure you're going to try really hard.

Now before we go, can you remember what I said at the start? What I want you to do, tell me what material is used in my background.

What materials do you think you can see? I can see? Good, the pipes are made from metal.

Great job, well done.

I am so impressed as usual with your hard work.

Shall we do a different cheer today? Shall I teach you a roller coaster cheer? Have you ever done one of those before? So for a roller coaster cheer you need to put your arms up like this to make your seat.

Then we're going to go up, up, and up, and then we're going to go, woo, woo, woo, like we're going down a roller coaster, you read? So we're going to go.

And another one, Then we're going to do three more.

We're going up.

and then three woos.

Woo, woo-woo, woo.

Great job, that's the roller coaster cheer, if you haven't done one of those before.

Well done today.

You have worked really hard, and I look forward to seeing you next time, bye.
