BELL RINGS Oh, I hate super-roller-disco day! | 0:00:02 | 0:00:04 | |
Why does Ms Hucklebuck always make us do it? | 0:00:04 | 0:00:07 | |
It gets easier, Dr Knowles, as long as you don't stop moving. | 0:00:07 | 0:00:11 | |
Does it, though? | 0:00:11 | 0:00:12 | |
Aargh! | 0:00:12 | 0:00:13 | |
Hey! Good morning, Dr Kno... | 0:00:13 | 0:00:17 | |
Dr Knowles? Hello? | 0:00:17 | 0:00:19 | |
-Down here! -Ah, what are you doing down there? | 0:00:19 | 0:00:22 | |
It's super-roller-disco day, | 0:00:22 | 0:00:24 | |
not creepy-crawly-fally day. | 0:00:24 | 0:00:25 | |
I just can't get the hang of these roller skates. | 0:00:25 | 0:00:28 | |
Whoa! | 0:00:28 | 0:00:30 | |
Oh... | 0:00:30 | 0:00:31 | |
MS HUCKLEBUCK LAUGHS | 0:00:31 | 0:00:32 | |
I just love roller disco! | 0:00:32 | 0:00:35 | |
-BELL RINGS -We're live in five, four... | 0:00:35 | 0:00:38 | |
This is Brain Freeze! | 0:00:38 | 0:00:41 | |
With Dr Knowles... | 0:00:41 | 0:00:42 | |
..Professor McCork... | 0:00:44 | 0:00:45 | |
..Colin, the floor manager... | 0:00:47 | 0:00:49 | |
and Ms Hucklebuck. | 0:00:49 | 0:00:51 | |
Stand by! | 0:00:52 | 0:00:54 | |
Come on, everybody! | 0:00:54 | 0:00:56 | |
It's time for... | 0:00:58 | 0:01:00 | |
It's more of a microscopic one, actually. | 0:01:03 | 0:01:05 | |
Today, we're asking... | 0:01:05 | 0:01:07 | |
Atoms are the fundamental building blocks of our universe, | 0:01:09 | 0:01:12 | |
and everything you see around you is made of atoms - | 0:01:12 | 0:01:15 | |
buildings, animals, water, air... | 0:01:15 | 0:01:18 | |
-Whoa! -Careful... | 0:01:18 | 0:01:20 | |
Atoms are unimaginably tiny, | 0:01:20 | 0:01:22 | |
and contain even smaller particles | 0:01:22 | 0:01:24 | |
called protons, neutrons | 0:01:24 | 0:01:26 | |
and electrons. | 0:01:26 | 0:01:27 | |
Depending on the number of protons in an atom, | 0:01:27 | 0:01:30 | |
it takes on a different form known as a chemical element. | 0:01:30 | 0:01:33 | |
So, for example, atoms with eight protons make oxygen, | 0:01:33 | 0:01:36 | |
20 make calcium | 0:01:36 | 0:01:38 | |
and 79 make gold. | 0:01:38 | 0:01:39 | |
Hang on a sec, though - | 0:01:39 | 0:01:41 | |
how are we made of those tiny little atoms? | 0:01:41 | 0:01:43 | |
In nature, atoms come together to form molecules | 0:01:43 | 0:01:46 | |
which form cells, | 0:01:46 | 0:01:48 | |
then tissues, | 0:01:48 | 0:01:49 | |
organs and, eventually, living organisms like us. | 0:01:49 | 0:01:53 | |
What? That's incredible, Dr Knowles. | 0:01:53 | 0:01:56 | |
Whoa! THUD | 0:01:56 | 0:01:58 | |
Dr Knowles? | 0:01:58 | 0:01:59 | |
Down here! | 0:01:59 | 0:02:00 | |
Ha! I think it's time for a break. | 0:02:00 | 0:02:03 | |
And we're clear! | 0:02:03 | 0:02:06 | |
Oh, no! This is the worst part! | 0:02:06 | 0:02:08 | |
It's actually not that bad, once you get moving. | 0:02:08 | 0:02:11 | |
Come on, Dr Knowles - you're missing all the fun. | 0:02:11 | 0:02:14 | |
CHEERS AND LAUGHTER | 0:02:14 | 0:02:16 | |
I think I'm getting the hang of this... | 0:02:16 | 0:02:18 | |
Yeah, yeah, I think I'm doing it. | 0:02:18 | 0:02:21 | |
I'm finally skating! | 0:02:21 | 0:02:23 | |
Whee! | 0:02:23 | 0:02:24 | |
Positions, everyone! | 0:02:24 | 0:02:25 | |
-BOTH: -Aargh! | 0:02:25 | 0:02:26 | |
So tell us, Dr Knowles, | 0:02:32 | 0:02:33 | |
how many of these teeny weeny little atoms are there in our bodies? | 0:02:33 | 0:02:37 | |
The body of an average adult human being will contain about | 0:02:37 | 0:02:41 | |
7 billion, billion, billion atoms! | 0:02:41 | 0:02:44 | |
That's a 7 followed by | 0:02:44 | 0:02:46 | |
27 zeroes! | 0:02:46 | 0:02:48 | |
Now, that's a big, big, big number! | 0:02:48 | 0:02:51 | |
Tell us, Doctor, where do they all come from? | 0:02:51 | 0:02:53 | |
A large number of the atoms in our bodies were made in stars. | 0:02:53 | 0:02:57 | |
Wha...? | 0:02:57 | 0:02:58 | |
Deep in the cores of stars, atoms are fused together, | 0:02:58 | 0:03:01 | |
with lighter elements fusing to form heavier ones. | 0:03:01 | 0:03:04 | |
Hydrogen is fused into helium, | 0:03:04 | 0:03:06 | |
helium into carbon, and so on. | 0:03:06 | 0:03:09 | |
When a star dies, | 0:03:09 | 0:03:10 | |
it fires these newly-formed elements out into the universe, | 0:03:10 | 0:03:13 | |
where they combine to make up all of the matter in the world around us. | 0:03:13 | 0:03:17 | |
So... | 0:03:17 | 0:03:19 | |
we're actually made from stars. | 0:03:19 | 0:03:22 | |
Pretty amazing, right? | 0:03:22 | 0:03:24 | |
I think that's the coolest thing I've ever heard, Dr Knowles. | 0:03:24 | 0:03:27 | |
See you next time, folks. | 0:03:27 | 0:03:29 | |
And we're clear. | 0:03:29 | 0:03:31 | |
Oh, I'm glad we won't need to worry about super-roller-disco day | 0:03:31 | 0:03:35 | |
for another month, Dr Knowles. | 0:03:35 | 0:03:36 | |
Me too. | 0:03:36 | 0:03:38 | |
I'm not sure I could take any more falls. | 0:03:38 | 0:03:40 | |
How's it going, lads? | 0:03:40 | 0:03:41 | |
All set for pogo-stick Sunday? | 0:03:41 | 0:03:43 | |
What? Really? | 0:03:43 | 0:03:45 | |
Come on, you two! | 0:03:45 | 0:03:46 | |
No room for watchers here! | 0:03:46 | 0:03:48 | |
Ha-ha! This is my favourite one - I love bouncing. | 0:03:48 | 0:03:51 | |
-Aargh! -CRASH! | 0:03:53 | 0:03:54 | |
Aargh, my leg! | 0:03:55 | 0:03:56 | |
And my arm. | 0:03:56 | 0:03:58 | |
And my head, | 0:03:58 | 0:03:59 | |
and my bottom. | 0:03:59 | 0:04:01 | |
Ouch! | 0:04:01 | 0:04:03 | |
Aargh, a little help here? | 0:04:03 | 0:04:05 | |
Colin, I think I broke the camera. | 0:04:05 | 0:04:06 |
