Intro Quiz: How can the shape of solid objects be changed?

Video: How can the shape of solid objects be changed?

﻿Hi everyone, and welcome to a science lesson with me, Miss Emms. I hope you'll feel excited and happy to be here. Hopefully you've done one other science lesson with me before this one, because in our last lesson, we learnt all about, our objects and materials that they are made of and the properties that those materials come from. I hope you're feeling ready for today's lesson, in which we are going to do the following. So let me show you our slideshow for today. Okay, here we go, everyone. So we are going to be thinking about how the shapes or how can the shape of solid objects be changed. That is our key question. And just to repeat, you are with me, Miss Emms. So, how can the shape of solid objects be changed? That is what we're going to have a go on answering today. Okay everyone. In today's lesson, we're going to follow this agenda, this structure. So we're going to start off with our star words, and then we're going to do a few recap questions, After that we're going to have a think about defining solid objects, so what is a solid object? And then we're going to think about how we can change their shape. And finally, at the end of the lesson, there will be an end of lesson quiz for you to do, to see what you can remember from today's learning. Okay, you're going to need a few things in this lesson. You're going to need an exercise book or paper. You're going to need a pencil and you're going to need your brains switched on and ready to do lots of great learning. You can also try and find the following things. Don't worry if you don't have them, you can always watch me use some of these items. But if you've got them in your house, I would love for you to find a container, so I've just got a water glass, I mean it could be a plastic tupperware, any kind of container, a box. But remember you need to ask your parents or carer if you can use it for your science lesson. If you've got a soft toy, then that would be great. And if you've got an elastic band or hair band, then that would be really useful as well. So pause the video now to go and get these things and these things if you've got them. Pause now, off you go. Great, okay, we're ready to start. Let's have a look at our star words, and some of you might like to stand up to do this 'cause it's a really energetic part of the lesson. Ready? You're going to repeat the word after me. And I'm going to tell you what they mean or explain that we'll come to it later. ♪ Star words, star words, star words ♪ Great, well done. Solid. Solid. We're going to learn today what the word solid means. So I don't want you to worry about that yet. Object. Object. We have to think in our first lesson about different objects, it basically means things. This pencil is an object. This sock is an object, the material is cotton. This pencil is an object, the material is wood. Okay, next one, are you ready? Squash, your turn. Squash, your turn. Bend, your turn. Amazing. Twist, your turn. Can you make sure you're doing the actions. Stretch, your turn. Wow, well done, amazing. Okay, a quick recap question now from our last lesson. I wonder, if you can name these properties based on our previous learning. Let me help you with the first one. So here, I know that this symbol means that this material is soft. Can you pause the video, point to the other properties and name what they were? Off you go. Amazing, did you manage to get them? Let's go over the answers. So we have soft and say it, hard, well done. We had absorbent, so easily able to soak up liquid and we had waterproof, repels water or doesn't let it in. We had transparent, so you can see through. And we had opaque, meaning you can't see through. Give yourself a pat on the back, if you've got those properties or even some of them. Well done everyone. Okay, so our recap's over and now we're moving on to thinking about solid objects. So, I wonder if you know already, what a solid object is. Have a little think, and I want you to tell me if you already know what a solid object is. Don't worry if you don't, just wait for the explanation. But if you do, can you say a solid object is ____? Off you go tell me now. Great, I had some great definitions of solid objects. I'm going to show you some solid objects now. First of all, we've got a picture of some pencils. We've got a picture of a wooden table, don't worry about the cup, it's more of a picture of the table. We've got a picture of a door, a front door. And we've got a picture of a kettle. Hmm, I wonder if that's helping you to have a think of what it means, for an object to be solid. What is the same about all of these objects? Can you tell your screen? Hmm, well done. So a solid object, is something that would keep it's shape when you put it in a container, okay? It does not feel the shape of the container. It keeps its shape, okay? Some of you might think that a solid object is just something that's hard, but that's not necessarily true. These objects are mostly hard, but this sock is also a solid object. And this is not a hard object, this is a soft object. So that's why we're going to use this definition. Something that keeps its shape when you put it in a container. So, let's have a go at testing that theory. I'm going to use a pencil now, and I'm going to put a pencil into two different containers or mainly one container. I'm going to try and put it. And we're going to see what happens. So, I'm going to stop sharing my screen. Here's my pencil. And here is my...I've said jar, you can use a jar or a glass or anything like that, a container. I want you to have a think, is this pencil going to change its shape when I put it in the container? Nod or shake your head depending on what you think. Yeah, most of you think it's not going to, let's check. So the pencil, I put it in the container. It's the same shape, isn't it? It's kept its shape. It has ____. Great, what if I put it in this one? Maybe it'll change if I put it in this one. Oh no, the pencil has maintained, it's kept its shape. Okay. What about if I do the same with some water. I've got some water in this container and I'm going to use it to pour it into first, this container and next, or let's start with the one we did before. First this container, and next this container, and we're going to see if the water keeps its shape. Okay, so let's start with this one. Okay, have a look at the shape of the water, it's not completely full, but it's filled the shape of the container it's in. I'm going to pour it back into this one now, and see if it does the same if I pour it into this container. Oh yes, it's filled the shape of the container that it's in. Whereas the pencil, didn't. That's because the pencil is a solid object. Okay? And a solid object, a solid object is something that keeps its shape when you put it in a container, okay? Keeps its shape, when you put it in a container, it doesn't fill the shape of the container it is in. So, we know that when I poured water into two different shaped containers, it did change shape. It took the shape of the container that it was poured into. So just as a quick recap question, I wonder, can you pause the video now and tell your screen, What is a solid object? You should pause and start with, "A solid object is something that ____." Ready? Pause and go. Great, a solid object is something that keeps its shape, when you put it in a container. Say it to me. A solid object is something that, keeps its shape when you put it in a container. Amazing. We're going to think now about how we can change the shape of solid objects. There are lots of ways, but we're going to focus on four, show me 4 fingers. Amazing. How can we change the shape of solid objects? So the first is squashing, I'm going to do an action for each of these. So I want you to, to go like this, you're going to move your hand down, because when we squash something, we push down. So you can change the shape of a solid object. Some can't be changed at all, but some, you can change their shape. And there are four ways. The first is squashing. The first is ___? Don't forget to do the action. The first is ____? Squashing, amazing. The second is bending. The second is ___? Well done, let's recap. So we've got number one, squashing. Number two, bending. Well done. Number three, and this is maybe a little bit harder to do. Number three, twisting. So one hand is going to go one way, and the other hand is going to go the other way. Twisting. Your turn, twisting. One more time. Twisting, well done. And the last one we're going to look at today, is stretching. Your turn. Like if you get up in the morning and you're feeling a bit sleepy, you might have a big stretch like this. Can you do that? Your arms are stretching. So our action is stretching, your turn. Amazing. I'm going to do them one more time. Are you ready do the actions with me? Ready, can you do it as well? Squashing. Bending. Twisting. Stretching. Can you do it faster? Squashing. Bending. Twisting. Stretching. You're getting fast, one more time. Squashing. Bending. Twisting. Stretching. Stretching. Amazing, well done everybody, amazing job. So what does this look like in practise? Let's have a look. We're going to look at me trying to do this to some different objects now. So first one is squashing. If I squash an object, I just push down on that object and perhaps I can change the shape. So I've got a sponge here. If I squash this object, okay. I push down on the object. Okay. So some objects you can squash and they maintain their shape from before and after that. So a squashing movement is where you go down like this. You can see with my sponge, that it's then going back, reverting to its original shape. So I can squash it, but it will move back to its original shape. Okay, let's have a look at the next way of changing the shape of a solid. Which is bending, bending. Okay, let's have a look at what it looks like. If I try to bend something, if I try to bend something. Again we're going to do it with the sponge. If I bend a solid object, remember squashing is down, bending is like this, and I can bend the shape of this object. Look, I'm bending it. So I was squashing by pushing down and bending like this, okay? Right, let's have a look at the next one. So the next movement, the next way of changing the shape of a solid was, twisting, twisting. So again, I'm going to use my sponge. We get to use more things later, but at the moment, I'm going to use my sponge and see, remember the twisting action's like this. Can I twist my sponge? Yes I can an twist my sponge, can't I? You can see that I'm twisting it up like this. With my sock, can I twist my sock? I can twist my sock, can't I? I can twist my sock. Let's have a look at the last way, which was stretching, stretching. Can I stretch my sock? Let's see, it's this length, can I stretch it? Oh yes, I can. I can stretch my sock. I've got an elastic band here, can I stretch my... I can stretch my elastic band. Can I stretch my pencil? No. Can I stretch my cloth? A little bit, but not very much. Okay, amazing. We're going to think about the movements now that we need to make in order to carry out these four ways of changing the shape of a solid. The first one was squashing. When you squash, which way do you push? Up, sideways or down? Tell your screen. You're so right. You push down, you push ___? Do an action, down, your turn. Fantastic everyone. When you bend, can you try and describe what the movement is when you bend. Tell your screen. When you bend, one part goes down one way, the other part goes down the other way. So that's why you've got those two arrows here. Bend, your turn, bend, well done. When you twist, can you try and describe what happens to your screen, when you twist, your turn? Amazing. When you twist your hands go sort of in opposite directions. Like this action here, twist, your turn? Fantastic. And when you stretch, this one's a little bit easier, when you stretch, which directions do you pull? Tell your screen. Away from each other, like this, stretch. So they're going away, your hands are coming away from each other, stretch in opposite directions like this. Okay. I want you to quickly answer these quick questions. So can all solid objects change shape in the same way? Do you think every solid object can change shape in the same way? Could I, stretch my pencil? No, I couldn't, could I? I couldn't stretch my pencil. Could I squash my sock? I can't squash it. I could scrunch it like this, but that's not what we're doing. We're not scrunching, we're squashing. If I squash my socks, and when I squash, I can do it just with my thumb and my finger. I can't squash it, it's not changing shape, is it? It's not changing shape. Whereas when I had my sponge, when I squash it, I can slightly change the shape, can't I when I push down. And can you bend a pencil? What would happen if I tried really hard to bend this pencil? It would____? It would snap or break. I can't bend my pencil. Okay, now it's time for an investigation. One of my favourite parts of the lesson. What I'd first like you to do before you investigate is to draw this table. And this part's really important, because when you're doing an investigation, it's really important that you are able to easily record what you find. So you don't need to do the pictures unless you'd like to, but you do need to draw the table, where your columns say object, squash and twist and stretch. And then the rows here say, sock, elastic band, sponge. And then at the bottom, you're going to choose your own object, an object that you have around your house. Now, if you don't have a sponge, you probably got socks in your house. If you don't have an elastic band, you probably got a sponge. Again if you don't have one, then you can change these objects for other things that you've got. But you need to have your four objects down in those rows. And what you're going to do, is you're going to investigate whether you can squash, bend, twist, or stretch each object. But first you need to draw this table. So don't worry about the images, unless you'd like to draw them to help you. Pause the video and on your piece of paper, with your pencil, draw this table. Off you go, pause now. Great, well done, everybody. Amazing job. So now, it's time for you to investigate. Shall we have a look at the first one together. And what you're going to do, is you're going to record your answers by putting a tick or a cross in each column, okay? So for example, let's have a look at the sock. Now we've done this a little bit before, but with the sock, this is the first thing I need to do, this here. I need to see if I can squash the sock, and if that changes its shape. As we've spoken about, I can squash it a little bit like that, but it's not changing the shape of the sock, is it? So I'm going to put a cross for sock. You might have thought it was going to be a tick because you can do the squashing action. But it's not changing the shape of the sock. So I would put a cross here. Can I bend the sock? I can bend the sock, can't I? The sock is very flexible. I can bend the sock, so I would put a tick here. I'm going to stop there, cause I don't want to ruin the fun for you to have a go at the rest of these by yourself. So you're then going to see, can you twist the sock? Can you stretch the sock? And then the same for the elastic band and the four actions, the sponge and the four actions and your own object that you're going to choose, and the four actions. Have fun, remember to record your results, pause the video, and complete your investigation, now. Off you go. Fantastic, everybody, let's have a little look now. Let's have a look at what you found. So sock, we said, we can't really squash the sock, but we can bend it, we can twist it and we can stretch it. So you got ticks in both of these, all in all of these ones. The elastic band you could, but you can't squash an elastic band, change its shape, but you can bend it, you can twist it and you can stretch it. The sponge, you could squash to change the shape of the sponge and you can bend it, you can twist it, you can stretch it as well. And I wonder would the object that you chose by yourself, perhaps you were or weren't able to do some of these things. We can't correct that, cause I'm not sure what you chose, but just check again, check your answers for that one again now. Okay, well done everybody. I've got a special challenge for you now. I wonder, can you find a solid object, which can't be squashed, bent, twisted or stretched. Can you find a solid object which can't be squashed, bent, twisted, or stretched. I want you to pause the video, go around your house now and see if you can find an object like this. Off you go. Did you get one? What did you get? Tell me. Great ideas. I thought of this, glass. This is a solid object, I can't squash it. I can't bend it, I can't twist it, I can't stretch it. So I could have put a water glass there. Okay. And then it's going to be time at the end for your end of lesson quiz. So to see how much you can remember from our lesson before you move on to the next one, next time. You have done such a good job today. I'm feeling really proud of you. I hope you're feeling proud of yourself. Let's do it, we're going to do a special clap for everyone doing this lesson who's tried so hard. And it's called a rainbow clap. It goes like this. Ah! It's just a really happy clap to show how hard you've all worked. I'll show it one more time. Ah! Like a rainbow one, two, three Ah! One more time. Ah! Amazing work, everybody. And I will see you next time. Bye everyone.
