• And we investigate why humans like music.
Budget 2018
Reporter: Erin Scott
INTRO: But first up today to the Federal Budget. That's something you're going to be hearing a lot
about this week as the government lays down its plans for how it's going to spend the country's
money. The budget is always a big deal for politicians and ordinary Aussies. So, let's find out more
about it.
Welcome to everyone's favourite game show Balancing the Budget.
HOST: Hello and welcome to Balancing the Budget the show where we put you in the shoes of
Australia’s Treasurer. I’m your host Scot Erinson and let’s welcome our contestant Sam. Hey Sam
are you ready to spend some Commonwealth cash?
SAM: Ah, yeah.
HOST: Great. You’ve now got an estimated 486 billion dollars.
Getting to spend billions of dollars of other people’s money may sound like fun but it's not that easy
just ask this guy - Australia's Treasurer Scott Morrison. It's his job to write up the Budget, which is
a document that tells us how the government is planning to spend all the money it collects in tax
paid by people and businesses.
HOST: Alright Sam, now it’s time to prioritise that government spending. So, which one of these
areas receives the most funding from the budget? Is it health, welfare, defence, education or the
environment?
SAM: Is it the environment?
HOST: Oh, sorry Sam, it’s not. It’s actually welfare.
Governments usually divide up the Federal Budget in similar ways from year to year.
Most of the budget generally goes to welfare, which helps people who need it like pensioners and
people who are unemployed. Health care is also a big expense. Last year the government spent
©ABC 2018
just over 77 billion dollars on funding hospitals and our public health system. Education and
defence also take up a fairly big chunk of the budget. And there's a big slice set aside for states
and territories as well as for things like disaster relief, local councils and paying off Australia’s debt.
HOST: Speaking of debt Sam, what do you call it when the Australian government’s spending
more money than it's earning in tax dollars?
SAM: Oh, oh a deficit.
HOST: Correct. Currently Australia's in a deficit but the Treasurer’s trying to change that. So, Sam
how do you choose to reduce Australia’s deficit? Well Sam, you could decrease government
spending, by spending less money on roads, hospitals and schools or maybe even grandma’s
pension or you could raise taxes, which means people have less money to spend, the economy
suffers, and nobody likes you very much.
SAM: Oh, neither of those options sounds great to me?
HOST: Correct, welcome to politics.
Trying to juggle the needs of so many people is really difficult, and budgets rarely make everyone
happy. But with an election coming up in the next year the government needs to impress as many
people as possible. That's why it's made some big announcements like more funding for the Great
Barrier Reef and for education along with some tax cuts.
SAM: So, did I win?
HOST: That's hard to say.
SAM: What do you mean?
HOST: Depends who you ask. Well, that's all we got time for here on Balancing the Budget we'll
see you again next year when we do it all again.
This Week in News
If you've ever dreamt of exploring the universe, you'll be pleased to know that Australia's a step
closer to getting its very own space agency. The government’s announced it'll pump 50 million
dollars into setting one up, although we don't know where it'll be based just yet.
Australia already plays a big role in space exploration, like monitoring satellites and getting
involved in missions to other planets. But we've never had a space agency of our own, so no doubt
there’s exciting stuff on the way.
Over in Hawaii, one of the world's most active volcanoes, Mount Kilauea, has been erupting
spewing ash, rock and lava into the air and through nearby neighbourhoods.
©ABC 2018
From a distance, it was pretty spectacular, but up close, it was chaos. More than two thousand
people had to evacuate, and more than 30 homes have been destroyed.
The eruptions haven't stopped, in fact, scientists say it could be months before this fiery giant
simmers down.
And back home, some impressive young Aussie artists have been showing off their skills in the
Young Archie competition. It's a junior version of the Archibald Prize which is Australia's most
famous portrait contest.
Young Archie entrants had to create a portrait of someone special to them and these are the
finalists. The winners will be announced in July.
North and South Korea
Reporter: Jack Evans
INTRO: Now to Korea, where there's been a lot of talk about a meeting between Kim Jong-un and
Moon Jae-in. They're the leaders of North Korea and South Korea. It's a really big deal because
the two countries have actually been enemies for decades. But now things are looking a lot
friendlier. Take a look.
At first glance it might seem like any other official meeting of leaders. You got the handshake, the
photo opportunities, a ceremonial tree planting, oh and even a cake. But this meeting had people
in Korea and all over the world really excited.
GIRL: It is amazing. Kim Jong-un and President Moon Jae-in don't seem like enemies. They seem
like friends as they shake hands in such a friendly way.
This was the first time these South Korean kids had ever seen their president shake hands with a
leader of North Korea. For all of their lives and all of their parents lives the countries have been
enemies. You see this whole area used to be known as Korea. But after the Second World War the
country was split in two. The US took control of the South and the USSR which included what we
now know as Russia took the North. They had some very different ideas about how the country
should be run and in 1950 North Korean soldiers invaded the South and the Korean War began. It
lasted for 3 years and involved several other countries including Australia. In 1953 the two sides
signed something called an armistice - which was an agreement to stop the fighting. But the war
never officially ended. A lot of North Korean people were kept apart from their families in the South
and they weren't allowed the same freedoms.
In the past few years North Korea has made some big threats against its neighbours. It's tested
nuclear weapons and threatened to use them. The situation had people right around the world
really worried. But now things are starting to look a little a lot friendlier. Earlier this year a secure
phone line was reopened so North Korea's leader Kim Jong-un could talk with South Korea's
President Moon Jae-in. And the two nations marched together under a united flag at the Winter
Olympics and competed with a joint ice hockey team.
©ABC 2018
Then came last week’s meeting which was the first time an acting North Korean leader had
stepped onto South Korean soil since the war. Many are hoping the meeting could bring an end to
one of the world's longest running conflicts, with both leaders saying they're working towards a
peace treaty that could end the Korean War for good.
Many leaders including Moon Jae-in say US President Donald Trump had a hand in bringing the
two countries together. He's planning to be the first US President to meet with Kim Jong-un later
this month. There's still a long way to go before the North and South can work out all their
differences. But many are hoping that this is a really positive first step towards lasting peace on the
Korean Peninsula.

Free-Range Egg Laws
Reporter: Ruby Cornish
INTRO: For a while now in Australia there's been a bit of debate about chickens and eggs.
No, not which one came first although that's still a good question. I'm talking about the free-range
debate. Lots of people are prepared to pay extra for eggs labelled free-range but until now there's
been some confusion about what that actually means. Let's find out why.
This is Charlotte, and this is Alexander, and today they're helping their dad Adam sort out eggs on
their family's egg farm in South Australia.
ADAM OATEN, EGG FARMER: Each egg is checked for cracks and then the machine weighs
every individual egg.
The eggs are sorted based on their size before they're packaged up ready for the shops. These
eggs are free-range, that means the chickens that laid them are allowed to roam around outside.
But not all chickens are clucky enough, I mean, lucky enough to have this much space. If you've
checked out the eggs at the supermarket, you'd know there are a few different kinds to choose
from. Caged eggs, meaning the chickens live in a cage. Barn eggs, which are laid by chickens kept
inside a barn or shed, and free-range eggs. Lots of people say they're willing to pay more for free-
©ABC 2018
range eggs because they reckon the chickens have a better life, but until now there’s been a bit of
confusion about what free-range actually means. Take Adam's farm for example.
ADAM OATEN: On our farm at Adelaide Hills Pastured Eggs we have a stocking density of 65
chickens per hectare, so that's one chook for every three-bedroom house.
But other farms that also labelled their eggs free-range kept many more chickens in a much
smaller area, and there were no clear rules about how much of the day free-range hens could
spend outside. Many farmers and animal rights campaigners said that wasn't fair. So, in an effort to
combat the confusion, new laws have been introduced for farmers who want to rock the free-range
label on their eggs. The rules say there have to be 10 thousand chooks or less in each hectare.
And every carton of free-range eggs needs to clearly show how much space their chickens have.
ADAM OATEN: We currently have our name and the size of the eggs, which is important, and we
also have free-range written on there, but our new logo will have a big red dot with 65 hens per
hectare.
There are also new guidelines being put together for caged and barn laid eggs, that are designed
to help famers look after the welfare of their chickens.
The new laws have definitely cleared up the confusion about what free-range means, but not
everyone's a fan of them. It could make things more expensive for farmers and maybe for
customers, too. Some say the laws are unnecessary because most farmers already try to look after
their chickens. Others, like Adam, say free-range farmers should have to give their chickens more
room.
ADAM OATEN: You're not getting a true free-range product anymore. Now, that’s one chook per
square metre, that’s not a lot of room for her to live her entire life.
While the laws have changed, life for the chooks on this farm will continue on as usual. And even
on soggy days like today, these hardworking chickens will keep the eggs coming.
Did you Know
Did you know an average hen lays around 300 to 325 eggs a year? That's a hard-working hen.

BTN Birthday Promo
At BTN, we love birthdays and this year's a really big one. Behind the News is turning 50 years old
and that means 50 cakes. Not really. But it does mean we want you to help us celebrate. Send in a

short video of your class wishing BTN a happy 50th. Then upload it to our website just like these
kids did.
Thanks guys. Send your best wishes soon, and you could even appear on our special birthday
episode. Want more details, it’s all on our website.
Sport
The story that had everyone talking over the weekend was the A-League Grand final between
Melbourne Victory and the Newcastle Jets and that extremely controversial goal which decided the
match.
Victory's Kosta Barbarouses scored the only goal in the ninth minute but the referee missed the
fact that his teammate James Donachie was offside, so the goal should have been disallowed.
A video replay could easily have cleared it up but there was a glitch in the feed at just the wrong
moment which meant the video ref couldn't see the offside. Football Federation Australia says it’s
now working with its technology partner to work out what exactly went wrong and how they can
prevent it happening again.
And how's this for the perfect wave? This is the WSL Wave Ranch in Central California home to
the longest open-barrel man-made wave in the world. It's the dream of Pro Surfer Kelly Slater who
wanted to give surfers the perfect wave every time.
Over the weekend it held its first comp, the Founders Cup. Mick Fanning was there with Team
Australia, but it was Team World that took out the top spot.
Meanwhile below the waves at the Gold Coast, this guy was taking a stroll for a good cause. Rod
Moore spent 4 hours walking underwater as part of a campaign to raise awareness for a kids'
charity called Kiwanis.
He's walked in Sydney Harbour and Lake Macquarie too, I guess it's a different way to get some
exercise.
BTN Audio update
Get excited, BTN has a brand-new audio update that comes out every weekday. It’s got all the
news you wanna hear told in the way that you wanna hear it. For the first time in a long time
Melbourne’s iconic Flinders Street Station building is officially pigeon poo free. Do you know that
old saying “don’t eat yellow snow”? It’s in a song. But I’m not sure what the go is with orange snow.
You can listen to it on the BTN website or if you have a Google Home or Amazon Echo you can
find it in the news section. Just search for ABC Behind the News.

INTRO: Bionic technology is pretty amazing. It's helping people all around the world to walk, see,
hear and do everyday activities. It's something that fascinated year 8 student Hannah so much so
that she decided to try building a bionic arm from scratch. Her friends didn't think she could do it,
but Hannah proved them wrong. Check it out.
HANNAH: Hi, BTN. I'm Hannah and this is the bionic arm I built.
As school assignments go, this one's pretty impressive.
HANNAH: So last year, we got this English assignment that meant over the holidays and into this
term we could research any topic of our choice. I decided to do one of my creatives and build a
bionic arm. Before this project, I hadn't really done anything that involved, I hadn’t used coding or
electronics or 3D design.
Hannah was fascinated by bionic technology, which is helping people regain the ability to do
everyday activities.
HANNAH: So, this hand can do a few different grips and hold many objects; so it can obviously do
a close just around something like a glass of water, it can pinch grip something - hold it nice and
firm - but also with fine motor skills it can open a door like that.
The year 8 student did lots of research into robotics and 3D design.
HANNAH: I got in contact with someone from the USA about robotics and 3D design. So, I
downloaded his open source hand - it was basically a flat version of a hand - and changed it into
this, so it could house different electronic parts.
She paid someone to 3D print the parts from their garage.
HANNAH: So, in total, I think the hand cost about $130 to print and build, for all the electronic
parts. This was my Christmas money.
So how does the arm work?
HANNAH: There are fishing wires running through the hand that acts as tendons and, at the back,
there is this flexible nylon cord which is similar to a hair tie, and this I guess makes the fingers have
upright as the natural position. It also uses Velcro and superglue to keep it all together.
These sensors are designed to go on a person's muscles and detect their movement.
HANNAH: Inside this hand is a little micro-controller, an ardweno nano board. So, I coded this
board so that when the muscle sensors get signals it sends it and it translates it in a way relevant
to the code, and this spreads it to all different parts of the hand; controlling it.
While Hannah's cat isn't that impressed with her creation. She's definitely amazed her friends.

HANNAH: They were like "Nah, no way you can't do that." So, we set a bet that I couldn't build it by
I think April the 1st, anyway, so one day I just brought it in to school and showed them and yeah
that was pretty cool.
Now, Hannah wants to keep developing the arm by adding extra sensors and different grips
possibly a positive for kitty-cat here. Ah, there we go. And it's only the start for this talented teen.
HANNAH: I think in the future, I'd like to continue developing robotic technologies - similar or
completely different to something like this and see how different robotics can influence the way
people interact.
Why do we listen to music?
Reporter: Jack Evans
INTRO: Hi BTN, my name’s Isobel and my question is: Why do people like music so much?
Whether it's classical, heavy metal or pop, there's nothing like hitting play on your favourite track
and letting the music take over. Music has existed for tens of thousands of years in just about
every culture around the world. But why we do we like it so much? Well that's a really complicated
question that's still got scientists scratching their heads. But there are a few ideas about why
people just can't beat the beat.
IDEA 1 - Music Makes Us Feel Good. Scientists have found that when we listen to music our brain
releases dopamine. That's the chemical in our bodies that makes us feel happy. The same thing
happens when we eat certain foods like chocolate.
IDEA 2 - Music Makes Us Move. Notice that when a song starts playing, even if it's not your
groove, you can't help but tap your foot along to the beat? It's something we do as babies, as these
internet stars can prove. That's because our bodies, our heartbeats and our brainwaves are
actually reacting the music in a process called entrainment. That gives us the impulse to tap along
or bust a move when we hear music. And that physical expression of dance makes our brain
excited. In fact, studies have found that dancing releases endorphins which are our happy
hormones and it makes us feel more comfortable and relaxed. Which is why for decades people
haven't been able to stop shaking their groove things.
IDEA 3 - Brains Love Repetition. Brains love repetition. Have you ever loved a song so much you
listen to it again and again and again? Well that's because our brains love repetition. Wait, didn’t I
already say that? All music uses repetition to make patterns and pop music is particularly repetitive
which is probably why it's so, well, popular. Even if we haven't heard a song before we often try to
predict how it'll play out by following the patterns we're familiar with. That's why some experts
reckon it can be harder for people to really get into jazz and classical music because it's less
predictable, so it doesn't give our brains the same immediate reward.
IDEA 4 - Music helps Us Communicate. Studies have shown that people tend to react in similar
ways to certain types of music. For example, angry music or peaceful music. It's a trick film and TV
makers use a lot. For example, here's me looking sad, and here's me looking hopeful, and here's
me looking heroic. Even if we don't speak the same language music can communicate emotions
and bring people together. Which is another reason why we say, "thank you for the music."
