Video: What is a material?

﻿Hi everyone, I'm Ms. Harris. Welcome to today's science lesson. What's your name? Lovely to meet you, now in this unit of work, we are going to be learning all about different materials. Now you might notice behind me is a type of material and every lesson I'm going to have a different background. And I want you to tell me right at the end of the lesson, what material you can see behind me, okay? Do you think you can do that? All right. Now, we are looking at this question. What is a material? Let's find out what today's agenda is. So these are all the things we are doing today. So we're going to be looking at what is a scientist, what is a material, we're going to look at some types of materials, we're going to be identifying materials. So looking at them and telling Ms. Harris what they are. And lastly, we've got our end of lesson quiz. For this lesson, you will need an exercise book or a piece of paper, a pencil, a coloured pencil, and most importantly, your brain. If you need to go and get any of these things, pause the video and go and get them now. Great. Now these are our star words. These are the important words we're going to be saying and using in this lesson. So it's important that we practise them. So we're going to start with the word at the top in white, and that word is materials. Can you say that word? Materials. So it's going to be my turn and your turn, materials. Then we're going to do this word here. Can you point to it? It says wood. What does it say? Good, plastic. Glass. Paper. Metal. Wool. Great job, let's do them moving fast, you ready? Glass, paper, wood, materials, metal, plastic. Wow, super fast. Now we are going to be scientists in this unit of work. Now do you know what a scientist is? So a scientist is a person who studies the earth around us, including things living or non-living. Let's do those actions together. So a scientist is a person who studies the world around us, including the living and nonliving things. But Ms. Harris, what are non-living things and living things? Let's have a look. So here, I've got two groups of pictures, which pictures, which side, this side, or this side, which side show things which are living? So you're right. The animals and the plants are the living things. And we are living things because we can breathe, we eat, we drink, we sleep, we reproduce. So that means to have babies. So these are all the things that a living thing does. Whereas on the other side, you can see some books and some pans, they are not living things. So scientists study things which are living and non-living. Here's some pictures of some scientists and everyone can be a scientist and you can see lots of different people conducted some experiments, take a closer look. So they've got lots of scientific equipment here. That's going to help them with their experiments, great. Now for your first task, I would like you to draw a picture of yourself as a scientist. Can you pause the video and have a go at drawing a picture of yourself, as a scientist. Well done, I'm sure your drawings look fantastic. Give yourself a pat on the back for working so hard already today. Now take a look here, what is a material? We're going to move to the next part of our lesson. What is a material? Now here is a definition of a material is. Let's follow with our finger, you ready? Can you put your finger on the first one that says everything. It begins with an e. Everything is, follow it with your finger made up of materials. Each material, back down here, can be used to make lots of different things. Okay, put your hands down. Listen now, everything is made up of materials. Each material can be used to make lots of different things. So what is made up of materials, everything. What is made up of materials? Can you say it to your screen? Everything is made up of materials. Let's pause the video. What is made up of materials? Can you say it to your screen? Let's see if you got it right? Everything is made up of materials. From your picture on the wall, to your toys and your teddies, to your clothes. The table that you might be sitting at, the chain you might be sitting on is made up of materials, your bag, your pencil, everything is made up of materials. Now we're going to at what types of materials that are. Are you sitting comfortably, are you ready? Have you have a little wake off, so you are nice and comfy, and you're ready. Because your brain is going to take in lots of information, you ready? Are you sure? Great, so the first material, which I'm sure you already know is glass. Glass is used to make lots of things that you might use every day. Glass is a hard material and it's transparent. That means if I hold up my glass here, you can see that we can see straight through it. It's transparent, it's... Good transparent. We can see straight through it. Can you see my face through the glass? It's transparent, it's really shiny and it's really hard. It's not squishy, I can't change the shape of it. It's really hard and transparent. Glass is hard and transparent. Glasses... Good, did you tell your screen? Let's try again, talk to your screen. Glass is hard, glasses.... And transparent, and... That means we can see through it. Great job. Are you ready for the next one? Be sure. So this one is called wood, great job. Have you seen wood before? You have, great. So wood is hard and opaque. Ms. Harris what does opaque mean? That's what you might be thinking. Opaque means that you cannot see through it. So I've got this little wooden box here. You can't see through this part of the wood because it's opaque. It doesn't light go through it. Apart from this whole here, but this part, the wooden part, doesn't let light to go through it, because it's opaque. It's hard, and opaque. Wood is hard and opaque. Wood is... Hard and opaque, good. What does opaque means? It means you can't see through it, good. Let's have a pause moment. What is the name of each of these materials? Pause the video and answer the question and press play again when you're done. What is the name of each of these materials? Great, so we have got wood and then the other side, we have got glass. With these two that we've done so far, wood and glass. Great job. You ready for the next one? Are you sure? Okay, ready? The next one is metal. Have you heard of metal before? You have, great. Now metal is hard and waterproof. That means it doesn't not let water or liquid in. I've got an example here. I've got an aluminium can, is a type of metal. You might recognise this because maybe you put your baked beans in here or your soup. Does the soup or the baked beans leak out of the bottom? No, because it's waterproof. It doesn't let liquids or water go through it. It holds that all inside, inside the tin. So it's hard and waterproof. So if I put something inside, it's not going to soak up all the water. So metal is hard and waterproof. Metal is... Good, is hard and waterproof. So here's the next one. You may already know this one. It's called plastic. What's it called? Good, plastic. Now I have got some plastic here in front of me. Plastic is waterproof and flexible or bendy. Flexible and bendy mean the same thing. So here is my plastic tub. Oh, you can't really see it. So this is my plastic tub. It had some strawberries inside of it. Have you seen one of these before? Good. Now it's waterproof because it doesn't let the liquid in. It doesn't absorb the liquid. So like a sponge that absorbs liquid, doesn't it? And I can squeeze it out. Whereas it won't happen to the plastic. It's also bendy cause I can squeeze it, watch. And I can bend it. Sorry, that was quite long. And I can bend it, move it because it's flexible. Now I squeezed it. Now it's a squeezed plastic punnet. So, plastic is water proof and bendy. Plastic is water proof and bendy, good job. Ready for the pause point. Ready, you're going to pause the video and answer the question and press play when you're done. What is the name of each of these materials? What is the name of each of these materials? Okay, ready for the next one? So now we have got paper. Which I'm sure you're writing on at the moment. So paper is, it is not waterproof and it is opaque. So let's have some closer look. It's not waterproof, if I put water on my paper, it will absorb the water and it will be all soggy. So it's not waterproof and it's opaque. So if I put it in front of my face, you now can't see me, because it's opaque. It doesn't let light through. So it is not waterproof and it's opaque. So paper is not waterproof and it's opaque. Paper is not... Good, waterproof and it's opaque, great job. Okay, ready for the next one. So here we have got fabric. Now there are a lots of different types of fabric. And fabric is used to make clothes or blankets. Lots of different things, your coat. And fabrics are often soft and they are translucent. That means sometimes you can see, it lets light through it. So it's soft and translucent. That means it lets some light through. So here I have got a type of fabric, it's called silk. You can see it's really shining. It's really soft. And if I hold it up to the light, sometimes you can see through it. It lets some light through it. So here we've got a translucent piece of material and a transparent piece of material. So one that let some light through, and one that lets all the light through it. So, fabric is soft and translucent. It's soft and... Good. Pause point. What is the name of each of these materials? Pause the video to answer this question. Okay, so we've got metal and glass. Did you get that right? Give yourself a pat on the back well done. Okay, now it's time to do some writing. So you guys need to pick up your pencil and you are going to be writing down what material this is. So here, I put the material is ____ and you're going to write that whole sentence down and write what the material is shown in the picture. Pause the video, have a go at that now. So now pick up your coloured pen or pencil. We are going to do something called ticking or fixing. That means we're going to fix what we have ticked. You ready? So this material is ___. Wood. Did you get that right? Give yourself a tick. If you didn't, don't worry. Put a nice, neat line through it and write wood above it. If you need to do that, you can pause the video now. Okay, great job. Ready, this is the next one. This material is ____. Pause the video and write down what material this is here. Okay, pick up your colour pencil. Ready to tick or fix. The material is fabric. Did you get that right? Give us a tick if you, and if you did it, don't worry. You can put a nice, neat line through it and write it above. Pause the video, if you need to fix your answer. Well done. Now it's time for our observation. This is what I'd like you to do now that the lesson is almost over. It's an activity that I would like you to do in your own time. How many different materials can you find? So I would like you to walk around where you live and see how many materials you can find and if you can name them. So first pick up an object then, right, say what it feels like. And lastly, identifying the material. Okay, let's check again. So first, pick up the object. Then I want you to describe what it feels like. Then you're going to identify the material. So what it's made of. So it might look like this, pick up this one. So, this is a cup. It's hard, it's really smooth. It's transparent, I can see through it. It's made out of glass. Okay. So that's what your observation will be this week. Okay, get ready. Now is something really exciting. Can you give me a drum roll, so take your two hands and you can bang on your lap like this, or you can do it on the table, you ready? So we're going to do three, do it for three seconds. Ready? Three, two, one. It's time for your end of lesson quiz. Did you know that's what it was going to be? So, now it's the end of the lesson. You can have a go at doing your end of lesson quiz. There are three questions that you need to answer. Can you see if you can get all three right? Great job. You've worked incredibly hard today and I am so impressed. But before we go, do you know what material is at my background? Can you shout out the material is... Wood, you're right. My background has got lots of wood. Well done today. Should we do a rainbow chain to end our lesson? So a rainbow chain is when you hold your hands out like this and we're going to make a rainbow using our hands. Do you think you can do that? Ready? We got to make this noise, aah. Can you ever get that, ready? Aah. Great job. I'm looking forward to seeing you next time, bye.
