# Lesson video

In progress...

Hello everybody.

Welcome back to your second lesson on human lifestyles with me, Miss Roberts.

You might notice that I'm wearing some funny clothes today.

That's because I've got my sports kit on cause we're thinking about exercise and why it's so important.

So if you want to go and put your sports kit on, you can go and do that now.

Look, Lenny the lion here even has his headband on and I've got my wristband, my headbands, and I've got my sports kit on.

So Lenny's going to sit by my screen and he's going to learn all about why exercise is so important.

So in today's lesson, let's have a look at what we're going to do.

We'll do our Star words, then we'll think about what exercise is? Then think about why it's so important? Then we have an investigation to do.

And then finally, I have a think question for you.

So in order to do all of these things, we're going to need an exercise book or a piece of paper, a pencil and your brain.

Then if you want to, you could get a timer and some colouring pencils.

You might need them, but if you don't have those things, then don't worry, you can follow with me.

Pause the video and go and get the things you need now.

Okay, let's do our star words, star words, star words.

Well done, my turn your turn.

Exercise, exercise, physical activity, physical activity, well done.

Movement, movement, strengthen, strengthen, important, important, and healthy, healthy.

Well done? Fantastic.

So first of all, let's think about what is exercise? And in order to think about it carefully, we need to know how to spell the word exercise.

The spelling is E, X, E, R, C, I, S, E.

Let's spell it together a little bit faster.

E, X, E, R, C, I, S, E.

E, X, E, R, C, I, S, E.

Can you whisper it? E, X, E, R, C, I, S, E.

E, X, E, R, C, I, S, E.

Can you shout it? E, X, E, R, C, I, S, E.

E, X, E, R, C, I, S, E.

Exercise, well done.

You are amazing.

Now just very quickly, I've got some slides and I want you to tell me which letter is missing.

E, E, R, C, I, S, E.

What letter's missing E, E, R, C, I, S, E.

What letter's missing? The X, well done.

Which letters missing? E, X, E, R, I, S, E.

E, X, E, R, I, S, E.

Ah! C, well done.

That's a tricky one.

Ah! Now there's a few letters missing E, X, E, R.

C, I, S, E.

Well done.

C, I, S, E.

Well done.

And can you spell it now with your eyes closed? E, X, E, R, C, I, S, E.

E, X, E, R, C, I, S, E.

You are amazing.

Check that you've got it correct and give yourself a pat on the back.

Well done.

Now, you know how to spell the word exercise.

Let's think about what exercise is.

So exercise increases your heart rate.

So exercise increases your heart rate.

So your heart rate is the amount of times that your heart is pumping each minute.

An increase means that it's doing more of it so it's getting bigger or more often.

I'd like to have a look at the screen.

What exercises can you see on the screen from these children? What are they doing to increase their heart rate? Can you tell your screen? Well done.

Have you managed to spot all of them? I can see a boy running, playing football on ice skates, someone doing some weights, a girl using the hula hoop, someone playing basketball, someone playing table tennis, a girl on a skateboard and another boy doing weights.

They are all doing exercise.

They're all doing, well done.

They're all increasing their heart rate.

They are all, their, They are all, their, well done.

I hope you'll speaking nice and loudly and proudly to your screen.

Here's another image.

What exercises can you see in this picture? Can you tell your screen? Well done.

I can see someone riding their bike.

I can see someone playing football.

I can see someone flying a kite.

I can see someone on roller blades and skipping.

I can see somebody reading a book.

Does that count as exercise? No, it doesn't because they're not moving their muscles.

I can see someone playing with a toy and a remote control.

Does that count as exercise? No, it doesn't because they're not increasing their heart rate.

So what is exercise again team? I'd like you to write it down, using your brain from what we've talked about so far.

Pause the video and write down what exercise is.

Well done.

Exercise is a physical activity that increases your heart rate.

Check that you've got the spelling from the words on the screen.

Well done everyone, I am really impressed.

Now that we've learnt what exercise is, let's have a look at the next slide.

Ah! What is your favourite way to exercise? I love going for a run.

I love running as far as I can until I'm really hot and sweaty.

And then I get to see, and then my phone tells me how far I've run.

What exercise do you like doing team? Can you tell your screen? Oh! Do you? Wow! What a great way to exercise.

So now that we know what exercise is, why is it important to exercise? Because it is important to exercise.

Exercise stops us from getting poorly.

Exercise stops us from getting poorly.

Exercise helps our bones and muscles to remain healthy and strong.

Exercise helps our brains to grow and exercise helps us to sleep well.

I'd like to pause the video here and tell your screen.

What are those four reasons why exercise is important? Can you use your finger and go across each box and tell your screen? Well done.

What I'd now like you to do is use all of those four reasons why exercise is important and draw a little picture of each of those in your notebook.

You can draw boxes like I have, or you can just draw them in your book in four different places.

So pause the video and have a go at your task now.

Well done.

I hope you've drawn all four of those images.

Now we're going to do an investigation.

So let's take a look, exercise what your heart rate? What does it do to your heart rate? It increases, well done.

Which means it gets faster.

So first of all, before we find out whether exercise increases our heart rate, we need to find our own heartbeat.

I like to find mine by placing two fingers, very, very gently on my neck, just on the side.

You need to make sure that you've asked an adult to help you with this, so that you can do it really safely and really carefully.

So go and speak to your adult now and tell them you were about to do an investigation all about your heart rate and exercise and check that they're happy for you to do it and they can supervise you to keep you safe.

So you can take two fingers and place it carefully on your neck.

You should be able to feel a pulse, which is the beat.

I can feel mine.

If you can't feel it there, you could also place your hand on your chest.

You might be able to find your heartbeat here.

Another way to find it is if you put two fingers, very gently on your wrist.

And if you're very patient, under your fingertips, you should feel your heartbeat.

I can feel mine on my wrist as well.

So what we're going to do is we are going to find our heart rate and see how many beats our heart beats in 30 seconds.

and see how many beats our heart beats in 30 seconds.

So I'm going to put my timer on my phone.

So let's get to 30 seconds.

Are you ready? Let's steady, go! And stop there, I got to 31.

What did you get to? I'm just going to jot down the number 31 and I want you to jot down your number to.

Now what I'm going to do now is I'm going to double 31.

So 30 doubled is 60, 1 doubled is 2.

So 30 doubled is 60, 1 doubled is 2.

So my resting heart rate is 62 beats per minute.

I'd like you to double your number and then jot it down on your notebook.

So now what we're going to do is we're going to do some exercise.

And we're going to do some exercise for one minute and we're going to measure our heart rate after that one minute.

So I am going to put my timer on my, I'm going to put my timer on, sorry.

And I'm going to put it for one minute this time.

I'm going to stand up, let's do this and, I've got my one minute timer on.

And then as soon as we finished, I'm going to sit down and I'm going to measure my heart rate in exactly the same way.

So you can do whatever exercise you like or you can follow with me.

I'm just going to do a mixture of jumping jacks and running on the spot, okay? Are you ready? So on your feet I'm going to stand up and I've got my one minute timer on.

We're going to be running for 10 seconds, running on spot, running on spot.

And I'm going to do some jacks.

Get my heart rate up without standing on stuff.

10 more seconds, 45 seconds, okay? Run on the spot Good job everyone.

I hope you're doing some exercise with me.

Woo! It's starting to get a bit hot.

It's very hot today and I'm going to do some bending down.

I'm going to get my legs working.

25 seconds left everybody, you can do whatever you want.

If you want to do some skipping, you can do that.

20 seconds left, and I go do some running on the spot for the last 15 seconds.

Really get my heart rate up cause I know that's a really good way to do it.

10 seconds jumping jacks, faster, faster.

We're not forgetting these.

And three, two, one, and there's the timer.

And three, two, one, and there's the timer.

Stop it and I'm going to put it on for 30 seconds.

And stop there right, jot down your number.

Woo! Mine was 38 that time.

Woo! Mine was 38 that time.

So I'm going to double it.

So mine was 38, I need to double 38.

So double of 30 is 60, 2 eights are 16 So double of 30 is 60, 2 eights are 16 so 76 is my heart rate after exercise.

so 76 is my heart rate after exercise.

My heart rate before was 62.

So I can say that my heart rate has increased because of exercise.

So if you did that with me, I wonder what yours increased to? Can you tell your screen? Well done.

And it's always good to remember that exercise increases your heart rate and we've just proved it.

So if you've not had to go yet and you were just watching me, then you can have a go at the task now.

Well done everyone.

I'm still recovering now after my increase of my heart rate.

And finally, I have another think question for you.

I wonder what you came up with? And who you spoke to about it? This week, I have a different think question for you.

How often should we exercise? Because exercising regularly helps us to keep really healthy, like we've learned today but how often should we exercise? Should it be once a day? Should it be once a week? Should it be once a month? What do you think? Hmm, I agree.

We exercise every single day.

We should exercise every day for at least 20 to 30 minutes, because that way we're keeping our bodies and our minds really healthy.

So have a discussion with either your people at home or with people at school and see what they think about how often we should exercise.

Go and have a go at you end of lesson quiz to help your brains grow even more.

You have done really well today, everybody, I am really impressed and I've really enjoyed exercising with you and so is Lenny the lion.

I'm going to take his headband off now so that he can say a big, well done and wave goodbye.

And we'll be here for our next lesson on human experiences.

Bye everybody.
