It's the time of the week where we
0:02
get very bored with life down here on
0:04
planet earth so we search through the solar
0:07
system for some secrets.
0:09
Let's get on with a brand new Fun
0:11
Kids Science Weekly. My
0:14
name is Dan, this is the only show
0:16
that discovers everything about science that no one
0:18
really has gotten to the bottom of. Apart
0:21
from us, can't wait to bring it
0:23
to you. This week we're trying to
0:25
unpack one of the simplest, but
0:28
hardest questions we've ever had really. How
0:30
does our brain work? All
0:35
of these signals going on in all the
0:37
different parts of the brain is what makes
0:39
our brain work, it's what creates behaviour. That
0:41
then gives us all of the experience that we have of
0:43
the world around us. And
0:46
in our mission to discover the best
0:49
science ever, we're heading into space. I'm
0:53
able to see the results of processes that
0:55
we see going on on the earth, but
0:57
studying them going on on other planets. Sometimes
1:00
we have rock as we have on earth,
1:02
sometimes we have ice behaving like rock. One
1:05
big thing at the moment is I'm looking
1:07
at great holes ripped in the ground by
1:09
explosions on mercury. And
1:12
you can hear why bananas are
1:14
a bit radioactive, it's all on the way
1:16
in a brand new Fun Kids Science Weekly. Let's
1:24
kick things off with your science in the news. Experts
1:26
say that people in the UK should get another
1:29
chance to see the northern lights soon. People
1:31
were amazed a couple of weeks ago
1:33
to see huge sweeping lights streak across
1:35
the sky, which you might have spotted.
1:38
Normally that only happens in the very
1:40
far north and only occasionally, but you
1:42
could see it way down south in
1:44
the country too. Experts
1:46
say that a huge sunspot cluster that hurled
1:48
energy and gas towards earth will come back
1:51
around in a week or so, which means
1:53
if you missed the aurora borealis
1:55
last time, you could get
1:57
another chance. How amazing is that?
2:00
Sometimes people spend a lot of
2:02
money, they travel across the world to see
2:05
the northern nights, they go to Iceland, the
2:07
very northern tips of Norway, but
2:09
you can see it here in the UK if that's where
2:11
you are. Also, still looking at
2:13
the sky, a blue fireball
2:15
lit the sky above Spain
2:17
up last week. Many
2:20
cameras show a suspected
2:22
meteorite streaking across the night
2:24
sky. The European Space Agency said that the
2:26
object looks to be a small piece of
2:28
comet. Isn't it amazing that we know so
2:30
much about the world and so much about space,
2:33
we've got so many technologies to find things up
2:35
there. Yet there's a massive
2:37
bit of rock, a comet flying
2:40
across our sky, and
2:42
it surprised everyone. I'm a big fan of
2:44
that. And our final story this
2:46
week, scientists have made an incredible 3D
2:49
model of what a Neanderthal woman might have
2:51
looked like when she was alive. It's based
2:53
on the flattened, shattered remains of a skull.
2:56
And Dr. Emma Pomeroy from the University
2:59
of Cambridge Department of Archaeology was vital
3:01
in this project and joins us now.
3:03
Emma, thank you so much for being
3:05
there. Just start us off and tell
3:07
us what we know about Neanderthals already.
3:10
So we know that they're one
3:12
of our really close cousins in
3:14
terms of evolution. Essentially, they evolved
3:16
in Eurasia about 400,000 years ago or a
3:18
bit before. At
3:21
the same time as our direct ancestors,
3:23
modern humans, were evolving in
3:26
Africa. And Neanderthals lived here a
3:28
long time. So they were around until
3:30
about 40,000 years ago. Then
3:33
we're not sure why. They went
3:36
extinct while modern humans, obviously us,
3:38
have continued to the present day.
3:40
And Neanderthals are pretty interesting. They're very similar
3:42
to us in many respects. But
3:44
there are certain characteristics that really make
3:47
them different from us. Things
3:49
like they have quite a big brow ridge. They're
3:51
forehead slopes back a little bit more. And
3:53
they're generally kind of heavier built and a bit more robust.
3:56
So how smart
3:59
were these? I guess animals, right? It's
4:01
weird to call someone so close to us animals.
4:03
But how smart would they have been? Would they
4:05
have been chatting away like we are right now?
4:07
I mean, that's a great question. And also in
4:09
terms of them being animals, I mean, ultimately, we
4:11
modern humans are animals too. But I think we
4:14
definitely think of them as being people like us.
4:16
One of the big debates in
4:18
our field is just how much
4:20
like us were they. And when
4:23
they were first recognized back in
4:25
the 19th century, people saw Neanderthals
4:27
as really sort of your archetypal,
4:29
knuckle dragging caveman who wasn't very intelligent,
4:31
and wasn't able to do most of the
4:33
things that we can do. But in the
4:35
last kind of 50 years, our view of
4:37
that has changed. And we're seeing them as
4:40
much more similar to us. So it
4:42
seems very likely actually, that they were,
4:44
they would have been kind of sitting and chatting away just
4:47
like we do. They have big
4:49
brains like us, I mean, on average,
4:51
maybe slightly bigger. And from what
4:53
we can tell, it's really hard to see that
4:55
from things like some of the bones in their
4:57
throat, and also from the structure of their ear,
4:59
they'd have been able to make sounds
5:01
like we do, they'd have been able to hear the
5:03
kind of sounds that we do. So yeah, I think
5:05
they'd have been sitting around chatting
5:07
and talking about whatever's
5:10
happened that day. And you've slightly brought
5:12
one to life. Now, there's an amazing
5:14
line in this story. So you've
5:16
used the flattened shattered remains of a
5:18
skull, whose bones were so
5:20
soft when found that they were like
5:22
a well dunked biscuit. So where
5:25
did we find some
5:27
small bits of bone to
5:29
start the process of bringing it to
5:31
life with this 3D model? Yeah, I
5:33
mean, it's been really tricky. So the
5:35
remains were actually found as part of
5:37
a bigger project called the Shahid Al
5:40
Qave Project. And we've been excavating in
5:42
this part of Iraqi Kurdistan for I
5:44
think 10 years now. And there've been
5:46
previous excavations there in the 1950s,
5:48
led by an academic called Ralph Zolecki. And
5:51
he'd found the entire remains there. So we knew
5:53
there was a possibility that we might find more.
5:55
And actually during our excavations, we noticed
5:57
in the wall of the that
6:00
we were working in, there were these little bits
6:02
of bone sticking out and we could tell that
6:04
there was probably a rib cage there, but
6:06
it was only when we excavated them fully,
6:09
which was really tricky because we're
6:11
about seven and a half metres from the
6:13
surface where we find these bones, so that's
6:15
really challenging in itself. And
6:17
yes, as we excavated down from the
6:20
top, we could see that there was
6:22
a relatively complete skull, although it had
6:24
been completely squashed flat and then broken
6:26
into many pieces. And as I said,
6:29
the bone was very
6:31
soft, which made it really hard to excavate.
6:33
I mean, if you touched it with a brush,
6:35
some of the bone would just start falling apart.
6:37
So yeah, how to get that out of the
6:39
ground and make sure we preserved as much as
6:41
we can was a massive challenge. So you've got
6:43
the bones out of the ground, you've managed to
6:46
keep them as well as you can. What
6:48
happens next? How do we get
6:50
this 3D model? So it's a
6:52
lot of painstaking, really hard work.
6:55
And I've got to give big
6:57
credit to the conservator on our
6:59
project, Lucia Lopez-Pauline, and she spent
7:01
over a year working on the remains
7:03
from this person. And the skull
7:06
itself took pretty much nine
7:09
or 10 months to clean all
7:12
the little fragments, what we
7:14
call a consolidant on them. So it's kind
7:16
of a glue that soaks into the bone,
7:18
and that helps it sort of stabilise from
7:20
the inside. And that means then we can
7:23
handle the bone and start figuring out how
7:25
we put the bits back together. So that's
7:28
something that Lucia did a lot of work on.
7:30
And I worked with her trying to figure out
7:32
what goes where. And that's actually a
7:34
process that's still ongoing. So the skull,
7:37
as it is, we've got really well
7:39
reconstructed, but there's more work to do
7:41
and more fragments to
7:43
try and get back in. So yeah, a
7:46
long term project. Oh, so
7:48
I'm seeing a picture here of a Neanderthal woman,
7:50
I believe it's the model. So
7:53
the actual bones are in it.
7:55
It's not like a computer composite.
7:58
No, exactly. So what we do, once we do that, we do it. sort
8:00
of physically reconstructed the bones and sort of
8:02
stuck back together as much as we can,
8:04
we then make a surface
8:07
model using 3D techniques. And
8:10
from that surface model that's in 3D, I
8:13
can then send that digitally to the
8:15
amazing Kennis brothers, who are the guys who
8:17
actually did the reconstruction of the face and
8:19
what she might have looked like in life.
8:21
And yeah, that reconstruction of the
8:24
skull that we've made is in
8:26
the middle of that physical reconstruction of
8:29
the face. And the Kennis brothers did
8:31
their thing, they reconstruct kind of the
8:33
muscles on the face, the thickness of the
8:35
skin, the fat, all those kinds
8:37
of things to figure out what
8:40
she might have looked like when she was
8:42
alive, which is so exciting. Well, thank you so much
8:44
for joining us, Dr. Emma Pomeroy. It's brilliant to chat
8:46
to you. Great to talk to you too. Thank you
8:48
so much. Thank you so much to
8:51
Emma Pomeroy for coming on the show, for
8:53
telling us what a 75,000-year-old Neanderthal
8:57
might have looked like. Let's
8:59
get to your questions, shall we? This is
9:01
my favourite part of the show. If you
9:03
have anything sciency in your brain that you
9:05
are wondering, something that you're not sure about,
9:07
that you've heard and you're thinking, how can
9:09
that possibly be true? Well, let
9:12
me know. I will do the digging for
9:14
you. I will call up a genius that I know and
9:16
we will sort it out. Best way
9:18
to do that is by leaving a voice note on
9:20
the free Fun Kids app or at funkidslive.com. This one
9:22
first has been sent in as a message by
9:25
Etienne in Scotland. Happy birthday, Etienne.
9:27
I know that that's coming up
9:29
soon, so have a brilliant day.
9:31
It's a random question. Do
9:34
bananas make antimatter?
9:37
That's bizarre, isn't it? We've
9:39
kind of heard about antimatter. It's
9:42
always in sci-fi programmes and superhero movies. It's
9:44
normally like what the bad guy in a
9:47
superhero film wants to use to take over
9:49
the world and to blow everything up, right?
9:52
Antimatter is a form of matter, so
9:54
a type of thing that is like
9:56
ordinary matter, but with the
9:58
opposite electric charge. And
10:01
when it comes into contact with
10:03
matter, something called annihilation happens, where
10:05
they destroy each other and they
10:07
can release a huge amount of
10:09
energy. Now we could spend days
10:11
learning just about antimatter because scientists
10:13
still aren't too sure about it.
10:16
But they do use what they know about it
10:19
in medical scans to help us better, to understand
10:21
the body. And the idea of it helps
10:23
us understand the universe as well. And
10:25
it turns out, at the end, the
10:28
bananas do make antimatter, a small amount
10:30
of it. They make positrons. It's
10:32
because bananas have potassium in there, which
10:34
is a chemical and a tiny amount
10:37
of potassium is radioactive. And
10:39
when that decays, when the
10:42
potassium breaks down, some of that becomes
10:44
a positron, which is a
10:46
type of antimatter. So
10:48
there's a lot of antimatter talk. It's
10:50
very confusing, but that's the
10:53
start of what happens. And
10:55
that's how bananas make antimatter. Maybe
10:58
we'll get a genius on to tell us about
11:00
antimatter in the next few weeks or so. Hmm,
11:02
leave it with me. Talking
11:05
about geniuses, let's get one
11:07
on to help us answer this question from
11:09
Owen. What have you got, Owen? How
11:11
does your brain work? Well, Owen, thank
11:13
you so much for that question. How do
11:15
our brains work? Well, Owen, I have to
11:17
tell you, I've been asked this question quite
11:19
a lot, and I've never been
11:21
able to figure it out. I've almost
11:23
been scared to even try to understand
11:25
how our brains work because it just
11:27
seems like such a monumentally massive idea.
11:30
But we need to try. So let's
11:33
chat to Dr. Laura Bubair from the
11:35
University of Westminster, who knows all about
11:37
this stuff. Laura, as I said,
11:39
it's such a massive concept. How
11:42
do we begin? Right
11:44
now, maybe I'm thinking about
11:46
talking to you, and
11:48
I can't see you, but maybe
11:50
I have an idea of what you might look
11:52
like, and I can see that picture in my
11:55
head. What's happening in my
11:57
brain at that point? fired,
12:00
what chemicals are going on, where is the picture
12:02
that I'm seeing actually happening? Well that picture
12:04
we have no idea, most likely in
12:06
your visual cortex which is the back of your
12:08
head. What's happening all of the time is that
12:10
our brain is like
12:13
a bundle of cables, so if
12:15
anyone's seen a picture of a
12:17
brain or maybe seen a brain
12:19
that's cut, it looks like
12:21
a blob and that's literally what it
12:23
looks like and feels like, but that
12:25
blob is made up of billions
12:29
of what looks like electrical wires.
12:31
So like the inside of a NOLED
12:33
computer, not like a new computer, each
12:36
of those wires carries
12:38
electricity and those, just
12:41
like the inside of a computer, each of
12:44
those wires which we call neurons, so nerve
12:46
cells, neurons, carry
12:48
electricity and the combination of
12:51
all of these signals going on in all different
12:53
parts of the brain is what makes our brain
12:55
work, it's what creates behaviour. That then gives us
12:57
all of the experience that we have in the
13:00
world around us. So there are different parts of
13:02
the brain that we know do different
13:05
things, so a little bit like
13:07
a car, for car to
13:09
work it's got an engine but
13:11
it's also got doors and windows
13:13
and electrical, there's a you
13:16
know there's a chassis, there's all sorts of different parts
13:18
of it for the car to work and if one
13:20
of those bits stop working then you're
13:22
going to have trouble getting to
13:24
your destination. So the
13:26
brain is a little bit the same in
13:28
that it's got different parts of the brain
13:30
that do different things, so for instance the
13:32
windscreen in the car or the desktop of
13:34
a laptop, we have that
13:37
and that's what we see and as you just
13:39
said you can imagine seeing things or you can
13:41
see real things. So the image that
13:43
you've got of me is going to be
13:45
based on all sorts of different things, obviously
13:48
you've got my voice, so from my
13:50
voice you're going to build up an
13:53
image and that image is going to
13:55
be based on your entire lifetime of
13:57
experiences of people's voices. So
14:00
from my voice, even if you didn't know
14:02
my name, you might guess
14:04
that I'm female, I'm a woman. So
14:07
from that, you're already going to create
14:09
an image which is based on your
14:11
template or your stereotype of a woman.
14:13
It starts with your mum, but
14:16
maybe a sister, friends, and
14:18
so you're going to build up that image
14:20
of what you think I look like. As
14:23
you noted just now, my name is
14:26
actually French. So for instance,
14:28
s'ilce que monsieur paulien franƧais, then
14:31
all of a sudden you might build a different image of
14:33
me. But also a different part of
14:35
your brain is dealing with language. So you've got
14:37
parts of your brain that's hearing the sound of
14:39
my voice, and a
14:41
very complex process then happens
14:44
to convert the sounds that you're
14:46
hearing, which are just a
14:48
bundle of sounds coming through
14:51
on the Ethernet, and
14:53
yet your brain is able to hear the
14:55
sounds, verify them, break
14:58
them down into all of the
15:00
individual components, match them up
15:02
to all the words that you know in
15:04
your own language, and then create
15:06
meaning from it. So
15:09
the brain, the left side, mostly the
15:11
left side of our brain, left hemisphere is
15:13
doing that. And what's really
15:15
interesting is that if you
15:17
have an injury to your brain, so
15:20
there are different causes, but it can
15:22
be through different illnesses, so through strokes
15:24
or maybe an accident, different
15:26
aspects of, for instance, our language can be
15:29
affected, so we can lose bits of it. You're
15:32
talking about imagery just now and
15:34
imagining what I look like. We
15:37
know that some people can't do
15:39
that, and that's something called aphantasia.
15:42
We know that other people, rather
15:44
than just hearing my voice, rather than
15:46
imaging, for instance, a person, they
15:49
might see colours, and that's
15:51
something called synesthesia. So that's where the
15:53
brain is wired
15:55
differently in different people.
15:58
So a little bit of an answer. Wow
16:00
and humans are hundreds of thousands
16:02
of years old and we still
16:05
really aren't close To
16:07
getting the full picture and the full answer
16:10
It's a fantastic start though. Oh and I hope
16:12
that's done a good job for you Laura boob

16:52
let's get to this week's dangerous down where we
16:54
look at the mean weird strange unique and deadly
16:56
things Across the universe this week.
16:58
We're heading under the ocean way down
17:00
deep to take a look at the
17:02
frilled shark You'll find it across
17:04
the world in parts of the Atlantic and Pacific
17:07
Ocean It normally lives quite close to the seabed
17:09
and it looks sleek. It's got a long body
17:11
of it like an eel It can
17:13
grow two meters long which is long It
17:16
has frills of skin which flow out of the
17:18
side of its head. That's how it gets its
17:20
name. It's got this big flat fathead
17:23
too with loads of teeth 300
17:27
teeth in there jutting from its
17:29
jaw. They're perfect for grabbing and
17:31
slicing slippery squid and small fish
17:34
Now it's called a living fossil Because
17:36
it's stayed the same for millions of years
17:38
looking and acting almost identically to how it
17:40
would have done all that time ago Way
17:43
before humans were above them. It's just been
17:45
floating around the bottom of the sea not
17:47
really changing and because where it lives is
17:49
It's very dark. It's almost pitch bad Humans
17:52
have rarely come into contact with them now
17:55
the frilled shark. It's an ambush predator It
17:57
lies in wait for its prey and then
18:00
And when something swims along not knowing
18:02
what's happening just out for a little
18:04
early morning swim maybe, the frilled shark
18:06
gets to work, it opens its long
18:09
flexible jaws, swallowing its
18:11
prey hole, which is very important because there's
18:13
not a lot of food way
18:15
down in the deep sea. So
18:17
you need to make the most of what is
18:19
there and swallowing prey hole means you get energy
18:21
from every single part of the prey and
18:24
you don't need to share it. Which
18:26
is also important if there's not a lot around
18:28
but because of its behaviour as an ambush predator,
18:30
because of its 300 teeth, because it
18:33
looks so terrifying and so ancient, the
18:35
frilled shark goes straight onto our dangerous
18:37
stand list. It's
18:42
time for battle of the sciences then. Every
18:45
week we pit experts against
18:47
each other. We find who
18:49
should come first in their
18:51
field. Geniuses all round the
18:53
globe pit themselves to be
18:55
the very best. And this
18:57
week we've got David Rothery
18:59
from the Open University, Professor
19:01
of Planetary Geoscience. So
19:03
much to unpack there David. But first you have one
19:05
minute to tell me why your science is the best
19:07
and it starts in 3, 2, 1, go! Wow,
19:13
I like geology on the earth. I like
19:15
getting out and about in the mountains and
19:17
visiting volcanoes and the like. And
19:20
now I'm doing the same thing but
19:22
on other planets. I
19:24
mean when I was a kid I wanted to be an
19:26
astronomer. I've not made it
19:28
to the stars but I'm doing it virtually
19:31
using spacecraft images on other planets.
19:34
I roam around looking at landscapes and I imagine
19:36
what it would be like to be there. But
19:39
more scientifically I'm able to see the
19:41
results of processes that we see going
19:43
on on the earth but
19:45
studying them going on on other planets.
19:48
Sometimes with rock as we have on
19:50
earth, sometimes with ice behaving like rock.
19:53
And one big thing at the moment is
19:55
I'm looking at great holes ripped in the
19:58
ground by explosions on mercury. There's
20:00
a bit of volcanic eruptions blasting holes
20:02
in the ground because there's gas inside
20:04
mercury that gets liberated when magma molten
20:06
rock reaches the surface and the gas
20:09
expands violently and blows stuff out in
20:11
giant explosions and these pieces of ground...
20:13
And that is your minute Dave, that
20:15
is your minute. So I mean it
20:17
sounds like an incredible job and you've
20:19
sold it very well. I'd
20:22
like to start with the question that many
20:25
people will say there's a lot going wrong here
20:27
on planet Earth at the moment with the climate
20:29
crisis. Why is what
20:31
you do important? Why should we be
20:34
spending time and spending money
20:36
and energy on looking at volcanoes in
20:38
space? By studying other planets
20:40
we understand the Earth that bit better.
20:43
Mercury for example is closer to the
20:45
Sun so when there are solar storms
20:47
affecting Mercury's magnetic field in the same
20:50
way that they can affect the magnetic
20:52
field on Earth we can study those
20:54
processes from a different perspective. If we
20:56
want to be concerned as we
20:58
should be about changing climates you
21:01
can look at Venus which has got a
21:03
thick atmosphere, lots of cold dioxide and it's
21:05
got a greenhouse effect far, far
21:07
more severe than anything on the Earth but
21:09
that's how the Earth could potentially end up.
21:12
A runaway greenhouse effect getting so hot that
21:14
the oceans evaporate. We need to know about
21:16
these things and how they've happened. Mars has
21:19
gone the other way. It's lost a lot
21:21
of its atmosphere. It's
21:23
very cold but it's had climates which have changed
21:25
dramatically over time and we
21:27
need to understand how that's gone on.
21:29
So by understanding processes on other planets
21:32
we get a better perspective on what's gone on
21:34
on the Earth. So it gives us a sense
21:36
of proportion and it gives us insights. In
21:39
your career looking at
21:41
volcanoes and other parts of
21:43
the geology of different planets
21:46
what's something really amazing and
21:48
mind-blowing that you've discovered? I
21:51
go back to the volcanoes on Mercury. There's
21:53
one place on Mercury where there's a whole
21:56
three and a half kilometres deep
21:58
and 30 kilometres across. That's
22:00
been blasted out by a volcanic explosion,
22:02
well not one volcanic explosion, we think
22:04
a series of volcanic explosions that have
22:06
happened there over a long time period,
22:08
maybe over a billion years from the
22:10
first to the last explosion, each time
22:13
blasting some more stuff out. And if
22:15
you were there standing on the brink
22:17
of this pit, it would
22:19
be a spectacular sort of Grand Canyon on the
22:21
earth, but in this case not carved
22:23
by flowing water, but by
22:25
a succession of giant volcanic explosions and
22:27
the debris that's been flung out from
22:30
this has gone 100 kilometres in all
22:32
directions away from the hole in the
22:34
ground. I think that's an amazing landscape
22:36
feature, we didn't expect that on Mercury.
22:39
Mercury near the sun,
22:41
just a burnt out cinder of dead
22:43
rock, no it's not like that at
22:45
all, it's got all these volatile elements
22:48
in it which can escape violently. So
22:50
it's the big surprises that keep me
22:52
particularly attractive to doing planetary science. Now
22:55
David, my last question, you've had a brilliant career
22:57
looking at these things, if I were to throw
22:59
you forward 20-30 years, when you
23:01
hang up your lab coat and you
23:03
put down your dreams and imaginings of
23:06
volcanoes on other planets, when
23:08
it's all done, what's one question that you would really
23:10
love to answer? What do you really
23:13
want to find out about what happens on different
23:15
planets? It's not a geology
23:17
question, it's has life ever got
23:19
started on any of these other
23:21
bodies. Mars once
23:24
had warm wet conditions, did life start
23:26
there? It's nice and warm and cosy
23:28
below the ice on some of Jupiter's
23:30
moons and some of Saturn's moons. You've
23:32
got warm rock with water on top, did
23:35
life get started there like it got started
23:37
on the Earth? That's a really big question,
23:39
you can start life in at least one
23:41
other place in the same solar system and
23:43
it's probably started all over the universe but
23:45
we only know one example where life got
23:48
started and that's our effort at the moment.
23:50
Just finding one more would change
23:52
our whole perspective. Amazing,
23:54
a brilliant fight for why
23:57
planetary geoscience should be
23:59
first. Dave Rothery, thank you for
24:01
joining us. You're welcome Dan, it was great talking
24:03
to you. What do you think then? Is
24:06
planetary science the best kind of
24:08
science? Does it win our battle
24:10
of the sciences? I think
24:13
it's up there right? It's in the
24:15
conversation. We'll have another one next week
24:17
on the show for you. But hearing
24:19
about space and planets with Professor David
24:21
has got me thinking about other things
24:23
that might be up there and why
24:25
we look out into space, what we
24:27
are hoping to find. So
24:29
let's jump through a wormhole to
24:31
the smartest school in the solar
24:33
system. We're heading to Deep Space
24:35
High joining Professor Polsar, who's
24:38
telling us all about why
24:40
we look through space every day.
24:42
Deep Space High, the universe handbook
24:44
with the science and technology facilities
24:47
community. Deep Space High, the
24:51
moon and space. But
24:55
hey, we've been learning about the
24:57
Earth. Deep
25:00
Space High, the
25:02
moon and space.
25:06
Right class settle down, I'm about
25:08
to be extra nice and you won't
25:10
want to miss that. Yeah, it's like
25:12
plistƩ's orbit, only happens once every
25:14
248 years. I
25:17
heard that. Your universe
25:19
handbooks are looking superb. From gravity
25:22
to wormholes, pulsars to parallax, you've
25:24
done a cracking job of getting
25:26
to grips with the frankly mind-boggling
25:28
reaches of space exploration. To reward
25:30
all your hard work, you can
25:32
all go home early. How about
25:34
that? Alright,
25:36
that's enough. We're not quite done yet.
25:38
To finish off this term, I asked you
25:40
to come up with some great reasons to
25:43
get exploring space. Who'd like to go
25:45
first? Well, a really great
25:47
reason to explore space is because
25:49
it helps develop cool inventions that
25:52
you can use on Earth. Or
25:56
any planet you like. Sorry blurb,
25:58
I forget Earth's not the the
26:00
only planet? Um,
26:03
aren't all inventions super clever engineering
26:05
things like rocket
26:07
exhaust pipes? I'm
26:10
sure they're very impressive and all that but
26:12
I wouldn't call them cool. Nah,
26:14
nothing like that. I've
26:17
bought a few inventions I use
26:19
every day that are a result
26:21
of space exploration. Here, cat,
26:24
this is my cycle helmet. I wear it
26:26
to protect my head when riding my bike.
26:29
It's really light, isn't it? Shock absorbing
26:31
foam in it was developed in the
26:34
1960s as part of the Apollo space program.
26:37
Nice! Love the colours too. It
26:39
looks like a nebula. Thanks,
26:41
I painted it myself after we went
26:44
nebula diving last term. Here's something else
26:46
I like playing with when I'm at
26:48
home. A
26:50
games console? I don't think astronauts on the International
26:52
Space Centre would get much work done if they
26:54
were playing rocket wars all day. Not
26:57
the game, the microprocessor inside
26:59
it. If it wasn't for
27:01
the space exploration, computers
27:03
might still be as big
27:05
as a room. And the joystick
27:07
was originally developed for Apollo's Lunar
27:09
Rover in the early 1970s. I
27:13
think the Lunar Rover would have been more fun to
27:15
play with than a computer game. Well,
27:18
yes, definitely. But these are a little
27:20
bit easier to buy. Very
27:23
good presentation, Alex. Ten out of ten. I think I've
27:25
been extra nice twice in one lesson. I'm on a
27:27
roll. Don't spoil it for me now, Stas. What have
27:30
you got for us? A
27:33
great reason to explore space is
27:35
that it's a challenge. A
27:40
challenge is usually hard work. And
27:42
a bit, well, boring.
27:45
Is it tricky level on that computer game if
27:47
yours boring? Or is riding
27:49
your bike down a really bumpy hill?
27:51
Does it send you to sleep because
27:53
it's just such a boring thing to
27:55
do? Nah, I love doing
27:57
that. There you go. Sometimes
28:00
things that are a challenge are brilliant
28:02
fun. That's actually true. I once
28:05
got stuck in a game for five
28:07
weeks, and when I completed it, I
28:09
was so happy I fell off my
28:11
bike. Probably shouldn't have
28:13
been multitasking there. You see, me,
28:15
I love a challenge. It's
28:19
easy to measure the stuff in front of
28:21
you. Anyone can do that. But who
28:24
wants to be just anyone? Being
28:26
able to work out how heavy a
28:28
star is, or to work out the
28:30
temperature on a distant planet from millions
28:32
of miles away, now that's the
28:34
really cool stuff. Fantastic.
28:37
That's... Who's next up? Electra? Come on,
28:39
then, let's be having you. Good
28:41
to see you tightly screwed together today. Off you
28:43
go before something works loose. A
28:46
great reason to explore space is because
28:48
it's exciting. You never know
28:50
what you might find out there. Maybe a
28:52
binary star system, a black hole, or even
28:55
a nebula that looks like that. I
28:58
agree with you, Electra. One
29:01
of the most exciting things of all that you
29:04
might find out there is other
29:06
life forms. That's right. After all,
29:08
not everyone can come to Deep Space
29:10
High, but everyone can get involved in
29:12
space exploration. You just need a
29:14
dark night and no clouds. And
29:17
on that happy note, we shall end the
29:19
lesson for today. But remember, it's just the
29:22
start of your space exploration adventures. Class dismissed.
29:27
Deep Space High, the universe handbook.

29:36
that's it for this week's Fun Kids Science Weekly.
29:38
Thank you so much for listening. We'll be back
29:41
next week on the show with another genius answering
29:43
one of your questions, someone
29:45
telling us why their science is the
29:47
best too, and we'll have
29:49
another brilliant episode on the podcast for you.
29:51
