Also very good. Good. Okay, you are quite loud, Charlie. Do you know how to turn your sound down a little bit? Miss, I think I like didn't print my like booklet. You didn't print your book up. Okay, we'll have a look at that in just a second. I'm just working on getting all of our volumes right. So anysay something else, please. Hello. Yeah. P, that's brilliant. Okay, super. So have you been sent the book laanyya? Have you been sent the booklet? Maybe no, maybe no. Okay, we'll have a look at the booklet in just a second. So I know and you're already let's get to know Rena and Charlie a little bit. How old are you? Rea 1111? And what's about you, Charlie? How old are you, Charlie? Oh, Oh, eleven. You're eleven as well. Okay. And and ya. Twelve so eleven and twelve. So you're all a similar age. Well, welcome to c two science course. And our first unit is animals, including humans. And we are looking at the heart. So I'll show you the booklet. Oh, in year six, we learn about the heart. And then like wait in year six, I remember. So like because that day we're like go like go to the secondary. Like and then because I'm primary, that time is last year. So I went, I, I went to a secondary and then like, I, and then like the science teacher in secondary, like they, because we just need to like go to try for secondary for one day. I can open that. And then, so in in that day, like the secondary, the teacher, she gave us like, a real heart, but it's like from pig and then like we just cut it and then look at like the meat. And then me and another classmate called Bonnie, and we are in one group. And then like we think the meat is very like what tastes good. Really? So it didn't make you feel a bit sick at all. No, right, this is the booklet, and you should have been sent this booklet to print. I'll see whether I can put it into the chat. In just a second. So each lesson you will have some worksheets, and this is where you will also find your homework. So have any of you had this booklet? I think my mom is pretty. Okay, so you have been sent to this booklet? Oh yes, right. Okay, so everybody has already been sent this Bookler, so try and get it printed for next lesson, please. Okay. Here we go. So let's start. And anyya, can you read the aim? I know the three main parts of the circulatory system and describe the job of the hergood circulatwell done and Yeah, good. And Reina, can you do this one here? Oh, I can, I can, I can, I can identify, identify the three main parts of the humcircucirculatory. Good. So this is one that people often get wrong. Identify. Thank you, Reina and Charlie. There's two there, the bottom. Can you do both of those? I can explain what the heart t does. I can work with others to create a living model of the circulatory system. Yeah, brilliant. Good, right? Let's see what we can remember. So can you remember the names of any organs in the body? So let's cut this out. And let's get a couple of copies. There we are. And I'm going to give you the pens, and I'm going to get you to draw some organs on. But you don't need to write the names. I will ask you to tell me the names. Okay, so we'll have this one is enyes, this one is Renus and this one is Charlie. So any organs that you can remember, draw them on? Okay, you've all got ps, now. Wait, I don't know how to draw the lungs. Yeah, don't say any of the names and ya not Yeah, let. Huh? Okay. We've definitely got some organs forming here. Brilliant. Wait minute. And Yeah, stop rubbing it out. That was fine. Don't worry about them being perfect drawings as long as we can get a vague idea what you're drawing. Okay, good. Charlie's got at least three things there and rea's got a couple. And Yeah get those back on. I will try. Wait. Yeah. All right. I think Charlie and Reina have finished. And yet just draw what you had back on again. And then I'm going to take away the pens. Wait, I think I know how to draw it now. And then here have another one. And then here have something thing that is very thin. Okay, that's I'm taking the pens away. I no, but time is up. Charlie, would you like to tell us about the organs you have drawn? So I'll give you the pen back so you can point to one of the organs you've drawn and tell us what it is. So draw an arrow on and tell us this is hurt, right? And this is stomach, and this is large. Inteand, small inside. Yeah. Brilliant. Charvery, good. Reina, you've got the pen now. This one is stomach. Wait, I change a color. And and this one is a small, interesting well done. Your stomach is a little bit low, should be a little bit higher up. But don't worry, these don't need to be that accurate. Okay. And ya, what have you got? No, choose a different color. Yeah basically this one like this one. Okay, so this one is long. Yeah. And then like this one is hurt. Good. And then this one, like the the teen one is like, wait, is this one wait? The diaphragm okay Yeah Yeah Yeah there you go right and then and then the this one like this one this one wait is stomach Yeah okay brilliant. Now obviously there's lots more organs in the body than just those, but well done that you all. We're able to name some of the organs in the body so brilliant. We don't need you to point to them on your body because you have drawn them. And then this was probably one of the most recent topics that you will have done, the digestive system. So here are lots of organs. Think some of you named the stomach, and we definitely had the small and the large intestines from Charlie. And there's a number of other organs. So well done. All parts of the digestive system, this unit, we're learning about the circulatory system. So the word circulation means movement to, from or around something. So this system is all about moving something. We've got some or false here, right? So Charlie, what do you think or false for number one? Pareno, what do you think? I don't know what is, I don't know what is the last word muscmuscles. A force ss and Enya, what do you think, right? Let's reveal the answer. It is yes, your heart is a strong muscle because it has to pump. What does it pump? Like the blood like blood Yeah the blood of sends it around the body. So it has got to be very strong to do that. So it's like a muscle. So it's doing this all the time to do this with your fist it's like clenching all the time and your heart, it's about the size of your fist. So all the time, all day long it is pumping. So it's a very strong muscle. Number two, Charlie, what do you think? Does the circulatory system contain the lungs? Okay renina. 呃呃呃。Fourth, and India. Let's see, it is false. The circulatory system does not contain the lungs. It is connected to the lungs. And the lungs are, is it latent? The oxygen, Yeah the oxygen will go inside and then like it when it like go to the like the heart, it will become like something, die carbon dioxide and Yeah, that all happens in the lungs, not in the heart. But like is it like it will go like make the something like the the air, something like go to the whole body? Yeah, we'll see that in a minute. Yeah. Like I said, the lungs are connected to the heart, but they are a separate system. So they are the breathing system or the respiratory system. So when we study the circulatory system, we don't go into any depth about the lungs. That would be a separate topic. Remember, everything in your body is connected. The body has tubes that blood flows through Charlie. A raa. And and Yeah. I'm sorry, I said, Oh, you said, okay, I didn't hear you. Probably ly, no problem, Reina, I'll change that for you. Okay, everybody got that one right. Does anyone know the names of these tubes? Because we don't call them tubes, do we? What's the proper word for them? No, I forget sometimes we call them blood vessels. There are two different types of blood vessels and we will come across those later on. So I won't tell you yet that the red one and then the blue one, Yeah, that's right, the heart. But they've got names as well. Have you ever have you ever seen one of these things here? A stethoscope? Have you ever seen one of those? Yeah. So what's it used for? Listen to your heart heartbreak a bit. Yeah, you can use it to listen to your heart. Charlie, what else could you listen to? I don't know any ideas, Reina, what else you could listen to with a stethoscope? The sound of the heart. Yeah, we've had the heart. Can you think of anything else you might listen to? Sometimes the doctor will actually put it on your back. What do you think they're listening to when they put it on your back and they say, take a deep breath. They are listening to listen to your breath, your lungs. Yeah, your breath. Yeah, that's right, Charlie. So they can use it to listen to your heart. They can use it to listen to your lungs, your breathing, to see whether you've got a problem with your breathing. They can listen to your intestines. And before we had more modern equipment, they might use it to try and listen to the baby's heartbeats if you were pregnant. But we've got more advanced equipment for that now. So it listens to sounds in the body. So it makes sounds much, much louder so the doctor can hear them. Right. We are going to have a little look at this knowledge organizer now it's in your booklet. So let's open up the booklet. Do you have this printed now, Charlie? Okay, Charlie, you can look at your printed page if it's easier for you. So this is something that you will get for every unit and it is a summary of everything that we are learning in this unit. And this one is two pages. So we are looking at the heart and that's over here. We have got keywords for the unit and definitions. And then we go on to looking at the blood vessels in detail. This is also about the heart. And then we look at what makes up our blood. More on blood vessels and a little bit on how to keep your heart healthy. So that's what we're going to be covering in this unit. Let me just rub out my scribbles. So you will need to refer to this knowledge organizer. And it will also be great to help you with your homework. And we'll be using it today to help with some questions. Any questions about the knowledge organizer? So when we draw a cartoon heart, a real heart does not look quite like that. Now ena has seen a real heart before, and this is what it looks like on the outside. So as I said, it's about the size of your fist. If you are a bigger person, you will have a bigger fist, your heart will be bigger, and it would need to be a bit bigger to pump the blood around your body. And a baby, of course, is not born with a heart the same size as an adult, so your heart will grow as you grow. Look at the knowledge organizer to see what a heart looks like on the inside. It looks like this picture here. So this is the heart sliced down the middle so we can see the inside. We'll look at another picture of this shortly. Okay, Charlie, can you read up to my Green mark please? The heart is a powerful organ that is seed through, situated, situated between your lungs and is protected by the. Rib cage. Rip rib cagood ina, rip kit and kitle ina. The heart is a muscle that comes blood all around your body. It is made up of four chambers, chambers. Enclosed spaces. Oh, enclosed space. Good. Thank you. And and ya, can you read this last bit? There are many tubes, cold blood vessels coming in in and out of the heart. The blood vessels Carry blood around the body. If they Carry blood away from the heart d, they are cold arteries. Arteries, if they Carry blood into the heart, they are called finveins. Okay. Yep. So remember, it is hot arteries and veins. Can everybody say that? Arteries. Arteries. Yep, good. Charlie Reina. And Yeah, everybody say arteries arveins good. So an easy way to remember this is a arteries stands for a way. So arteries Carry blood away. So that letter a helps you remember the direction veins has got in in the word. So they Carry blood in to the heart. So that will help you remember which direction. We're going to watch a video now about the human heart. So let's get that playing. I'll just play it and check that the volume is okay for you all. And the heart, unlike other. Okay, can everybody hear that? Yep. Was the volume okay? Okay, brilliant from the beginning. The human heart for kids, take a moment and put your hand on the left center of your chest. Do you feel something? It is your beating heart. Let's learn some amazing facts about the heart and how it works. The heart is one of the most important organs in the body and is essential for survival. About the size of a fist, it is located on the left side of the body, behind the breastbone in a, so it's a little bit off center, just towards the left, so just a little bit area called the sternum. The heart is also protected by the rib cage. Now it mentioned the rib cage in the part that you were just reading. So that's what the rib cage is made of, bones. What do you think the job of the rib cage is? Rea, what's it for? Sorry it again, what is the job of the rib cage? What does it do? I don't know. The rip cawhat is the rib cage. The rib cage is, I don't know if I can draw on the White bones here on this picture that look a little bit like a cage. Yeah. What's it for? Why do we have that? It protect the orgyes. Yes, it protects the organs. We know how important our heart is. We wouldn't want to get it squashed. So the rib Cade protects the heart and of course, the lungs, because they are both so important. The heart is part of the circulatory system. It is the process that circulates or moves blood to and from the heart. This system carries vital oxygen and nutrients to every cell. Let me just go back a minute. Right. And Yeah, let me just get a good picture. I'll pause in a second. And ya area called the sternum. The heart is also protected by the rib cage. The heart is right here. Enya, why are some red and some blue? It's like for the the the blood is like sending outside and some is like go into the and then like some is like again, like Yeah the one the colors is blood going into the and one of the colors is blood going out of the heart. The circulatory, the blue wall. It is the go outside the heart. Heart yes, circulates or moves blood to and from the heart. This system carries vital oxygen and nutrients to every cell in the human body. The two main parts of the circulatory system are blood vessels, which include arteries, veins and capillaries. Okay, so that's the different types, arteries, veins and capillaries. He pronounced it capillaries because that's the American pronunciation. So arteries, veins and capillaries. So arteries and veins ending capillaries. We'll look at these next lesson. So don't worry too much about them. And the heart. Unlike other muscles in the body, the heart beats automatically. This means you don't have to think about making your heart beat. It just does it for you automatically. This is because your heart is controlled by the autonomic nervous system. In fact, in 24 hours, your heart averages around 115, zero beats per. That is a lot, isn't it? 115, zero beats per day. So your heart has to be a very strong muscle. And just like your digestive system, you don't have to think about it to make it work. It happens automatically. Your brain just controls it for you day. And in that same amount of time, the six quarts of blood in your body travels twelve zero miles. That's the equivalent of driving across the United States from coast to coast four times. That is amazing. The average heartbeat of a kid is around 90 beats per minute and will be faster or slower based on what you're doing. When you are moving your body, your heart beats faster because your body needs more oxygen. And when you're resting, your heart beats more slowly. Let's look more closely at how the heart functions. There are four main parts to the human heart. The left and right ventricles are at the bottom of the heart. So we call these four parts chambers, because a chamber is an enclosed space, a little bit like a room. So it's like your heart has got four rooms, so we've got two at the bottom. And they're ventricles. You can remember that because you should be able to see there a bit. Oh, I can't draw. They're A V shape. Yeah. They're pointed at the bottom like A V that helps you remember that the ventriles are at the bottom. The left and right atriums are at the top. Blood is pushed from the atriums into the ventricles on each side of the heart, as small valves open and shut during every. So these valves are a little bit like doors. So the chambers or the rooms are connected by a door. Now these doors can open and close, and they are called valves hearbeat. Think of them as little gates that open and close each time the heart beats. These gates make sure the blood flows in the right direction. Yeah, otherwise it would go backwards and we wouldn't want that. So that's why they close. So he said they're like gates. So you could think of them like gates or doors. Let's follow the path. Blood takes through the heart. These drops of blood have just come from the lungs and are now right? So we're starting at the lungs. So is there going to be oxygen in this blood if it has come from the lungs? What, you think it has come from the lungs, Charlie, will it have oxygen? Try again Yeah and are said look, it's yes, yes, yes. Oxygen comes from the lungs, so the blood goes to the lungs to get the oxygen. So this blood will have lots of oxygen genated, meaning they are full of oxygen and are ready to go. They come from the lungs and are pumped through the left side of the heart, through this gate, and then are spread throughout the entire body by blood vessels. Think of blood vessels like little train tracks, taking blood where it needs to go. Chew, chew. Next stop. Good. Once the blood has traveled throughout the body, they come back. So has this blood on the blue side got lots of oxygen? No. So we call this deoxygenated because the oxygen has been taken away and it has been used by all of our cells. So where do you think this blood is going to go to next, Enya? What does it want to get more of? Oxygen. So where's it going to go? Lung, yes. Going to go back to the lungs again. So that's why the lungs are closely linked with the circulatory system. But when we study all the systems, we don't study the lungs with this system, but they are really linked. But now to the right side of the heart, just like the four from up here through the gate, and then these drops of blood are pumped back to the lungs to gather more oxygen and do the same thing again. As blood is moved through your body, through the circulatory system, it not only carries the oxygen your body needs, but other important things as well, like food, minerals and vitamins. These things help your body move, grow and make repairs. It also helps you think the stuff in your blood that your body does not need is sent out as waste through your lungs, kidneys and liver. Here's a fun fact. The trip for a drop of blood to travel throughout your body takes only about one minute. Since the heart is a necessary part of the body, it is important to care for it and keep it healthy. Here are some ideas to keep your heart healthy and working for a long time. Exercise. The heart is a muscle, and just like other muscles in your body, exercise can help it become stronger. Eat your vegetables and fruits like exercise food affects your heart too. Eating lots of vegetables and fruits help keep your arteries clear, to help blood flow through your body and more efficiently. Drink plenty of water. Keeping yourself hydrated by drinking water is essential to keeping your heart pumping blood. This is because 75% of your brain and heart are made up of water, and your blood is about 83% water, which means you need to drink water to keep your heart healthy. Remember to move. Sometimes when we are doing homework or watching a screen, you might forget to get up and move around. It is important to take breaks and move your body. It's good for your heart and your mind. The human heart is a pretty cool organ. As part of the circulatory system, it pumps your blood through your body and carries oxygen, nutrients and minerals to all of your cells. The coolest part, you can help make your heart stronger. So the next time you go to a friend's house or to school, see if it's safe to walk or ride your bike instead of drive, and make sure you drink plenty of water. Hope you had fun learning with us. Okay, brilliant. So we got lots of information from that video, some of it we will discuss more. Next lesson when we look at the blood vessels. Okay, we have got a worksheet. Now, if you have not got this printed now, Charlie, you have got this printed. Reina and Enya, you're going to need to get some paper so you can work on paper. And as part of your homework, you can transfer your answers to your booklet. Ts, no, no, like my mom, just give me. You've got it. Brilliant. Reina, do you have it? Okay. Have you got some? Let's see. I think we might need scissors for this. Let's have a look. What we can do to save a little bit of time is we won't cut them out. We can just order them, right? Let's just write them in order and that will be a little bit quicker. We get time at the end. We can always go back and cut them out. So we've got to get the correct order here. So number them. So don't worry about cutting Charlie. Just number them, Charlie, without cutting. If we have time at the end, we'll come back to it and we'll cut. But for now, just put numbers if you think that's two, if you think that's three and so on. So I'll give you a minute, read through that and decide on your order. Harley, what have you got as number two? Which one do you think is number two, Charlie? Oh. The blood that is full of oxygen travels to the heart. Thank you, Reina. What have you got? His number three. You have to turn your sound on, rea your microphones off. Sorry. The down of the the second one arteries Carry blood away. Yeah this one maybe what do you think is number four? And Yeah from here, the blood gets pupumped back to the lungs to pick up more oxygen so that the whole cycle can wait, wait. No, that's the end. Wait. Dennis beans Carry blood back to the heart. Got it. Okay, so that's our roduso. Let's go to the PowerPoint and double check that. But that's the order that you should have. Blood travels to the lungs, picks up oxygen. Blood full of oxygen travels to the heart. Arteries Carry blood away from the heart. Veins Carry blood back to the heart. And from here, the blood gets pumped back to the lungs, and the cycle starts again. All right, everybody got that written down. Let's move on. Like I said, we can cut it out if we get time at the end. So is your fist the same size as my fist? Are our hearts the same size? Well, my fist might be a little bit bigger than yours. No, everybody's heart is a slightly different size. As I said, a younger child is going to have a smaller heart than an adult, and an adult man is going to have slightly larger heart than an adult female. Let's go on to our next worksheet now, and you are going to need to look at your knowledge organizer to help you with this one. So the next worksheet. We have got to write the labels from the body to the lungs, from the lungs to the body, from the body. So write your labels in the boxes. If you need some help, you can go to the knowledge organizer. There you are. Can you see how you can get some help? Now the colors should help you, because when we have red, that helps us to remember that this is rich in oxygen, and when it's blue, that helps us to remember that the oxygen has been used up. Now that's not the actual color in the body, of course, that's just what we use for diagrams. Okay, Enya, what have you got for label number one and number two? From the body. And number two is from the body. Brilliant, Charlie, what have you got for label number three? From the lungs, from the lungs. Okay, Reina, what have you got for number four? Two longs and end, yet last one, number five, to the body. To the body. Brilliant. Good. Well done, everybody. Right next one. We have got some questions. Now let me just check that these are the same questions on the PowerPoint. Pretty sure they are. Yeah. So we've just been through this. That's the correct labels. Right now, this is different. We'll come on to that in a second, right? Let's have a go at this one now. Use as many keywords as you can from the box to write three statements about the heart. You can use your knowledge organizer to help you, so you can just write them here on the worksheet. For example, you could say the veins Carry oxygen around the body. However, it is asking about the heart. So we can probably get a better answer than that. We could say. The heart has four chambers that might be better. I use three statements there, three words. Okay. I'll give you a few minutes to have a go. Everybody happy with what you need to do. Brilliant. And I'm going to give you one more minute. Okay, let's start with Charlie. What have you got? Charlie? Share one of your statements. Heart. Is a strong muscle to help your body work. Brilliant. That used two of the words, very good. Marina ina, would you like to share one of your statements? The. Color the color of blood on the diagram is. Is. Is go into the heart and to the body. Good. So you use two words, brilliant. And Yeah a heart have bof wait, four chambers. And. The wait, wait, wait, wait. The blood will Carry the oxygen. Wait, the blood will Carry the oxygen. Passing those chambers. Very good to to wait to send to send energy to into our whole body. Wait to send blood. Yeah blood, no energy. Okay, brilliant. Now I have just hosted your homework as a homework task, so you'll get a little link in the chat. This is your homework here. You have got this worksheet here. Label the heart. And then you have got this one here with some tick boxes and fill in the missing words and you have got some reading to do. Now the reading will probably help you with the homework sheets and maybe do the reading first. Okay. Okay, so that is your homework. Let's just do a Little Review at the end. We should have some and false. Let's have a look. Okay, here's our review. Now this one here we haven't done yet, so we will do this one next lesson. So we don't need to worry about this, but we have studied the heart. So you should know the heart pumps blood to the lungs to get oxygen. It then pumps this oxygenated blood around the body. Or false? And Yeah, this one is for you. Is the heart a strong muscle? How come? Why does it need to be a strong muscle? Because the heart humlike hump the blood and send the blood to our whole body. That's brilliant. And it is pumping all of the time. So of course, if you use your muscles a lot, they do get strong. Well done in ya, Charlie. Does the circulatory system contain the lungs? Force. That's right. Even though the lungs are strongly connected, we study the lungs when we do the respiratory system, when we look at how we breathe in and out and all about the oxygen and the carbon dioxide. And Reina, does the body have tubes that blood flows through? Well done. Yes they are called blood vessels and that is what we are going to study next lesson. So you've got your homework and you've got your reading. Make sure you bring your booklets for next lesson. And we have finished. So it's been lovely meeting you and I will see you again next week. Any questions before we finish? Okay, see you next lesson, bye.
