Oh, hello there! I love this experiment. Hee-hee.

I'm trying to see how far away I can get from the glass

and still drink the juice.

-Yes, I managed to get a drink!

-BEEP BEEP

I hear a beep, I see a flash. I wonder what they're going to ask.

-ALL: Hi, Nina!

-Hello!

-We've got a question for you.

-Why do we need blood in our body?

That's a great question. Why do we need blood in our body?

Our bodies have blood moving around them but what does it do?

Why not come down to my lab and we'll investigate.

ALL: See you soon, Nina. Bye!

I'll need help to answer this one and I know who to ask.

-OK, Neurons.

-Time to get to work!

ALL: Neurons at the ready, Nina.

Today's question is, "Why do we need blood in our body?"

Which Neuron will be most useful to answer that?

ALL: Me! Me! Me! Oh, me!

Will it be fabulous Felix?

I can help so very much if you need the sense of touch.

Will it be beautiful Belle?

I send messages to brain from ear. If there's a sound, I'll help you hear.

-Will it be lovely Luke?

-For looking and seeing, day or night,

I'll help with your sense of sight.

-Will it be awesome Ollie?

-If it's pongy or whiffy but you can't tell,

-my messages help your sense of smell.

-Or will it be baby Bud?

Sour, salty, bitter or sweet, I'm your taste buddy whenever you eat!

-It's Luke!

-Yes!

ALL: Go, Luke! Go, Luke! Go, Luke!

Go, Luke! Go, Luke! Go, Luke!

Cool, Nina. I'll be looking out to help you.

Today's question is, "Why do we need blood in our body?"

Blood is a red colour we can see,

so Luke, our sight Neuron, is helping me.

Stand by, Neurons. I may need help from all of you.

I'll get the lab ready before the experimenters arrive.

George likes football. Ryan likes curries and Gary loves superheroes.

But they all want to know why we need blood in our body.

So today, for one day only, George, Ryan and Jack are the Experimenters!

-Hi, guys!

-ALL: Hi, Nina!

Welcome to my science lab. Come in.

Now, you asked "Why do we need blood in our body?"

A great question but why do you want to know?

If we fall over and cut ourselves, sometimes blood comes out.

We want to know why blood is in our body.

Yes, if we cut ourselves, sometimes a bit of blood comes out

but it's nothing to be afraid of because it usually stops quickly.

There's lots to find out so let's start by using our senses.

ALL: Woop-woo! Our senses experiment. We're ready, Nina!

Blood is a runny liquid in our bodies.

We don't have any blood here

but we do have a runny liquid in these beakers.

Water. I've added some colouring so we can see it better.

Let's count the beakers together!

ALL: One, two, three, four, five.

Yes, we have five beakers of coloured water.

Does that look like a lot of water?

-Quite a lot.

-That's right.

Each beaker has one litre of coloured water in it.

And someone about my size has about five litres of blood inside them.

Which is all five of these beakers.

How much blood do you think children's bodies have?

-A bit less?

-Well, a child about your age and size might have

about two and half litres of blood inside them which is this much.

Wow, Nina. That's a lot of blood.

I know, Luke, our bodies do have quite a lot of brilliant blood

but where is it all?

This is a picture of the inside of our bodies

and these red lines are what we call blood vessels.

Blood vessels? Oooh, I like the sound of that.

Blood vessels are a bit like little roads inside our brilliant bodies

but instead of cars, it's blood that travels along them.

Or through them. Because blood vessels are little, tiny tubes.

To see how, do you want to pick up this great, big tube here.

What can you see happening to the coloured water inside?

-The water's moving around the tube.

-That's right.

If we imagine that the red water inside the tube is blood,

we can see how blood moves through the blood vessels around our body.

And...where do the blood vessels go to?

Head, arms, fingers, legs...

-And feet!

-And feet, that's right!

But why do we need blood to travel every part of our bodies?

Let's go somewhere to find out more.

-It's time to get our pulses racing!

-ALL: Yay!

Here we go! I can't wait to see where we'll end up today!

Nina said something about racing. Perhaps we're going to a sports day.

With funny sack races and a three-legged race.

And my favourite, the egg and spoon race! Ha-ha!

I've a feeling, it's a different kind of racing.

Sharpen your senses, Neurons. We're here.

Our senses experiment showed us that we have lots of blood vessels

that carry blood to every part of our bodies.

But why does the blood do this?

Our blood is made up of lots of very important things,

including something called red blood cells.

Did Nina say, "red mud smells"?

No, Ollie. Red blood cells.

Red blood cells carry something special around the body

and drop it off where the body needs it. A bit like a delivery driver.

Do you guys fancy making deliveries in these speedy go-karts?

-ALL: Yay!

-OK, great.

You will pretend to be red blood cells and you're going to deliver...

these balloons.

-So, who can tell me what's inside this balloon?

-Air.

-That's right.

Air contains the special thing our bodies need called oxygen.

Oxygen is an invisible gas and we breathe oxygen in from the air

and red blood cells carry it around the body

where it's needed to do lots of important things.

OK, take a balloon.

On your marks, get set...

BEEP BEEP!

ALL: Yay, look at them go!

Come on, the red blood cells! Get that oxygen moving!

That's an oxygen being delivered to the hand.

Oh, good job, red blood cell Gary.

Ryan picked up some more oxygen and he's taking it to the leg.

Fantastic work!

Oh, and a lovely delivery to the brain by Gary.

What about the feet? They haven't had any oxygen!

Oh, that's it!

Good delivery of some oxygen there by red blood cell George. Well done!

Fantastic! You delivered the oxygen to the different parts of the body!

We discovered that our blood is made up of lots of different things,

including lots and lots of red blood cells.

These have the important job of delivering oxygen around our body.

Other stuff is carried around our body in our blood.

Like water. And good things from our food which we need for energy.

What else does blood do? Back to the lab for a final experiment!

ALL: Yay!

As well as the red blood cells that carry oxygen,

our blood also contains white blood cells.

White blood cells helps us fight off infection.

-Anyone know what infection is?

-Is it when you get ill?

-It can be.

Infections are caused when tiny, invisible bugs called germs

get into our body and make us ill.

Germs are often found on our hands

which is why it's so important

to wash your hands before you eat and after going to the toilet.

But if germs do get into our bodies,

our white blood cells find them and destroy them.

For this experiment, we're going to imagine that this red paddling pool

is some blood and let's look at the big balloons above us.

We'll pretend the green balloons are nasty germs that cause infection.

You've got to spot any green germ balloons that get in to the pool

and burst them! Because you're going to be the white blood cells.

-Everyone ready?!

-ALL: Ready, Nina!

Watch our for those green germ balloons!

Come on, the white blood cells!

Oh! This is the noisiest experiment ever!

One left! Get it!

Brilliant, guys! You all did an excellent job as white blood cells.

You spotted the nasty green germs that shouldn't be in our body

and destroyed them, protecting the body from infection. Well done!

Your question was, "Why do we need blood in our body?"

I think we've answered it. We discovered that blood travels

from the tops of our heads to the tips of our toes

inside little tubes called blood vessels.

Our blood carries important things around the body,

like water and the good things from the food we eat.

We also found out that our red blood cells deliver the oxygen

that our bodies need to do many special jobs.

Our white blood cells destroy nasty germs that could cause infections.

-I hope that's answered your question.

-ALL: Thanks, Nina! Bye!

Bye!

Ah, it's been such a great day, man.

Seeing all those blood vessels.

They go to every part of the body.

I really enjoyed myself today.

The children had such fun pretending to be red blood cells.

I've had a fabby day!

The white blood cells fighting off the nasty germs were fantastic!

And remember everyone's body is different but they're all brilliant!

-See you again, soon! Bye!

-ALL: Bye!
