BELL RINGS Oh, I hate super-roller-disco day!
Why does Ms Hucklebuck always make us do it?
It gets easier, Dr Knowles, as long as you don't stop moving.
Does it, though?
Hey! Good morning, Dr Kno...
Dr Knowles? Hello?
-Ah, what are you doing down there?
It's super-roller-disco day,
not creepy-crawly-fally day.
I just can't get the hang of these roller skates.
MS HUCKLEBUCK LAUGHS
I just love roller disco!
-We're live in five, four...
This is Brain Freeze!
With Dr Knowles...
..Colin, the floor manager...
and Ms Hucklebuck.
Come on, everybody!
It's time for...
It's more of a microscopic one, actually.
Today, we're asking...
Atoms are the fundamental building blocks of our universe,
and everything you see around you is made of atoms -
buildings, animals, water, air...
Atoms are unimaginably tiny,
and contain even smaller particles
called protons, neutrons
Depending on the number of protons in an atom,
it takes on a different form known as a chemical element.
So, for example, atoms with eight protons make oxygen,
20 make calcium
and 79 make gold.
Hang on a sec, though -
how are we made of those tiny little atoms?
In nature, atoms come together to form molecules
which form cells,
organs and, eventually, living organisms like us.
What? That's incredible, Dr Knowles.
Ha! I think it's time for a break.
And we're clear!
Oh, no! This is the worst part!
It's actually not that bad, once you get moving.
Come on, Dr Knowles - you're missing all the fun.
CHEERS AND LAUGHTER
I think I'm getting the hang of this...
Yeah, yeah, I think I'm doing it.
I'm finally skating!
So tell us, Dr Knowles,
how many of these teeny weeny little atoms are there in our bodies?
The body of an average adult human being will contain about
7 billion, billion, billion atoms!
That's a 7 followed by
Now, that's a big, big, big number!
Tell us, Doctor, where do they all come from?
A large number of the atoms in our bodies were made in stars.
Deep in the cores of stars, atoms are fused together,
with lighter elements fusing to form heavier ones.
Hydrogen is fused into helium,
helium into carbon, and so on.
When a star dies,
it fires these newly-formed elements out into the universe,
where they combine to make up all of the matter in the world around us.
we're actually made from stars.
Pretty amazing, right?
I think that's the coolest thing I've ever heard, Dr Knowles.
See you next time, folks.
And we're clear.
Oh, I'm glad we won't need to worry about super-roller-disco day
for another month, Dr Knowles.
I'm not sure I could take any more falls.
How's it going, lads?
All set for pogo-stick Sunday?
Come on, you two!
No room for watchers here!
Ha-ha! This is my favourite one - I love bouncing.
Aargh, my leg!
And my arm.
And my head,
and my bottom.
Aargh, a little help here?
Colin, I think I broke the camera.
It's roller disco day and everybody is having loads of fun, except for Doctor Knowles who just can't quite seem to get the hang of it! The crack TV science team investigate how many atoms there are in our bodies.
