Today in the clubhouse, we're getting terrific and scientific.

Let's Goer Natasha shows us what it's like to be an inventor.

We're going double-digital with facts about computers and robots.

Our CBeebies friend Dr Ranj is in the clubhouse.

And I'll be showing you an EGGcellent experiment -

the egg drop.

Let's go!

Hi, my name is Natasha.

I'm eight years old.

This is my cat, Griselda.

I have six cats altogether...

THEY MEOW

-..and I love cuddling all of them.

-GRISELDA PURRS

MEOW!

I love jumping high on my trampoline.

I play the violin and the flute.

SHE PLAYS GREENSLEEVES

But there's one thing I really love - science.

I really love doing experiments at home with my mum.

Measuring, mixing, pouring,

swirling, spurting and squirting.

It's fun to watch the chemical reactions.

SHE LAUGHS

I want to be a marine biologist when I grow up.

I love learning about animals.

I love using my microscope to look at things up close.

I also really like inventing.

These are some of the things I've invented.

What's this invention?

-This is the pollen shoe.

-OK.

It helps bees because, if you step over flowers,

the pollen goes onto the bottom of the shoe

and when you walk it spreads the pollen.

This is the nose scratcher.

It's basically a ring

and there's a little robot arm

that goes up and scratches you on the nose.

Sometimes, when you've got an itch in your nose

and you itch it with your finger,

it looks like you're picking your nose.

People say, "Yuck, you're picking your nose,"

but you're actually itching your nose,

and it'll come up and itch your nose for you.

-And no-one will know that you're really itching your nose?

-Yeah.

That's really clever.

I like finding out how things work.

Sometimes, I make robots with my mum.

This is Lizzie - she's a robot lizard.

-Let's see if it works.

-Great.

Look at what she can do.

I love science.

Bye-bye.

Now then, Let's Goers, I bet your brains are buzzing with ideas.

You know, I've always fancied invented something. Ta-da!

May I present the round of applause stick?

CLAP, CLAP!

-CHEERING

-Now, I can clap myself.

Thank you. Thank you very much. That's enough of that.

Now, take a look at this.

It's time for an EGGcellent experiment -

the egg drop challenge.

For this, you will need an egg,

a cardboard tube,

a plastic cup with some water in it,

and a non-breakable tray.

So we take our cup of water.

And we place our non-breakable tray over the top of it.

And make sure it's in the middle.

Then, we take a cardboard tube and put that on top, too.

And that goes in the middle as well.

Finally, we take our egg

and we balance it very carefully

on its side on top of the cardboard tube.

OK, here comes the exciting bit.

So I'm going to need an audience.

Come on, guys!

Hey, Willow, hey, Rowan, hey, Francesca.

-How are we?

-ALL:

-Good.

Now, I'm going to hold on to my cup

very carefully and I'm going to give

my tray a strong tap, but not too hard.

And what should happen is

my egg should fall into the water.

Are you ready, guys?

-ALL:

-Yeah!

One, two, three.

ROWAN SQUEALS

It landed in the water.

It did land in the water.

That's what I call an EGGcellent experiment.

Let's see that again.

When the tray is gone, there's nothing to hold the egg up.

Gravity pulled it down into the water.

I think I deserve a round of applause.

-CHEERING

-"Well done, Kirsten."

Thank you. "You're welcome, Kirsten."

Do you dare to take on the daring egg drop challenge?

If you do, remember to ask a grown-up first,

because it could get messy.

Make sure you send us your sciencey photos and videos as well.

Now, speaking of science,

it's time for some fun facts about robots and computers.

Let's go!

First up, one of the first-ever

robots was a steam-powered pigeon.

What a lot of hot air.

A clever man from Greece called Archytas

wanted to learn more about how birds fly.

So he built a robo-bird.

The robot pigeon could fly the length of two football pitches.

The only problem was that,

once it landed, the pigeon

couldn't take off again to fly home.

It had run out of steam.

ROBOT PIGEON CHEEPS

Next, the very first computer was heavier than an elephant.

That's a weighty fact.

The computer was Colossus and was as big as a bus.

BEEP, BEEP!

But only a few people knew about Colossus because it did

top-secret jobs - cracking codes and finding out spy information.

-Sh!

-WHISPERS:

-Don't tell anyone.

Next, there are robots on the planet Mars.

That is out of this world.

The robots are called Mars rovers and took months

and months to get to the Red Planet.

Their job is to do experiments so that we can learn

more about Mars and find out if anything lives there.

Just one problem - no-one has

worked out a way to get the robots back,

so they are stuck on another world forever.

It's a good job robots don't get lonely.

And, finally, in South Africa, traffic lights are called robots.

Let's put the brakes on.

Back in the olden days, policemen organised the traffic,

telling cars when to stop and when to go using hand signals.

Then, electric traffic lights were invented.

They replaced the real policeman

so people started calling the lights robot policeman.

And, over time, this name was shortened to just robots.

That's red, amber and green for go-bot.

Fact.

Let's go!

Techno-tastic facts right there.

A steam-powered pigeon? What a hoot!

Or would that be an owl? Anyway, we've been finding out

-lots of cool facts today in the clubhouse, haven't we? ALL:

-Yeah.

Now, there's a doctor in the house. It's Dr Ranj!

-Hey.

-Hi, guys. Am I right in thinking

that you've got some questions for me?

We have been having a bit of a think.

Harriet, you had a good question.

Why do people sneeze when they have hay fever?

Brilliant question, Harriet. After the winter,

when all the plants and flowers are growing again,

they release pollen into the air.

Usually, that pollen doesn't cause problems.

For some, it gets into their eyes, nose and mouth,

and tickles. That's what makes you sneeze.

-That is hay fever.

-Wow.

-Have you got a question as well, Scarlett?

Why do people wear plaster casts when they break a bone?

Your bodies are amazing. When you break a bone,

your body can mend it again.

It's a bit like two pieces of a broken plate -

you glue them back together, that's what your body does.

Because it takes such a long time, it's got to hold them

there for a long time. That's what the plaster cast does -

it holds them together so they glue together in the right way.

Isla, did you have a question?

-How small are germs? How do they make you ill?

-Oh, wow.

Well, germs are tiny. Smaller than the eyes can see.

There's two types of germ, mainly -

something called bacteria and something called viruses.

They're everywhere, all around us, and some are inside us.

The good germs live inside us and on our skin. They help us,

and the bad germs make us poorly.

When a bad germ gets inside our body, it gives us

something called an infection, and that's what makes us sick.

Our bodies are really good at fighting them off.

Sometimes, we need medicine to help us.

Dr Ranj, I've got a question.

This little bone in your elbow, when you hit it and it feels funny?

Why is it called a funny bone? Why's it feel like that?

A funny question, because that isn't even a bone.

We call it a funny bone because there's a nerve that runs

down there. When you hit that part, it's actually

the nerve you hit, and that's what makes it go weird and numb.

And makes you feel funny. But it's not the bone, it's a nerve.

-Interesting fact, isn't it?

-I had nooo idea.

I had no idea. That was really great.

I feel like I've learnt something.

I know a lot more than I did

when I was eating my breakfast this morning.

They were some great questions, Let's Goers.

-Thanks for having me in your clubhouse.

-Oh, it's a pleasure.

Now, I've got a fact for YOU.

Did you know that you can use two books to have a tug-of-war?

No, I didn't!

Well, prepare to be amazed, because it's time for We Did This

with some science-loving Let's Goers.

# The Let's Go Club. #

Let's go!

Hi, I'm Subal, and these are

my friends Olivia, Billy and Sophia.

We love science, and today we're going to do some experiments.

Today, we're going to learn about friction.

Friction is the force between two surfaces that are sliding.

Or trying to slide across each other.

When things are smooth, there's less friction.

When things are rough, there's more friction.

Go!

Friction has slowed this car down

because it's on a bumpy surface.

Sometimes, the force of the friction

is so big you can stop something

moving altogether.

Which is what happened next.

We are layering the pages to see how many

we could stuck together

before they get too hard to separate.

If you pull it apart like that,

it is quite easy, isn't it, because there's not much friction?

More pages on. 19...and 20.

OK, try and pull it apart.

Pull them really hard.

When all the friction is added together from lots

of different pages, it is very hard to separate them.

We can't pull apart these books.

We need to super-size this experiment and get some help.

Just like the notebooks,

these catalogues are attached

together only by their pages.

Three, two, one. Go!

We are going to try and pull them apart.

All those little bits of friction

between the papers add up to lots of friction.

Stop! Friction wins!

We love science, and We Did This.
