Population of your class
As a class discuss what you want to learn about the population of your class. Develop questions to
investigate student’s experiences, opinions and interests. When designing your classroom census, keep in
mind that you will need to respect privacy and protect confidentiality. For example, do not include your
names on the census.
Here are some questions students could include in their questionnaire:
• Which state/territory and country were you born?
• How many languages can you speak?
• What is your favourite food?
• How many hours of sleep do you normally get on a school night?
• What actions do you take in your home to conserve the environment?
Reflection
• What interesting things did the data tell you about your class?
• How could the results collected from this data help your school make better informed decisions?
Make a time capsule which includes the data gathered from your classroom census. Future generations at
your school will be able to learn about the population of your class and then compare to their own.
Run that Town
Run that Town! Use real Census data to discover who’s who in your area,
and make decisions that will sway popular opinion in your favour. Choose
from hundreds of projects for your town - from the practical to the
preposterous. What kind of leader will you be? Will you be treated to a
ticker tape parade, or chased out of town by an angry mob?

Amelia Earhart – Create a biography
Before students begin to construct their biographies, hold a class discussion to find out what they already
know about biographical writing. Discuss what type of information is included in a biography and what they
tell us about a person. The Civics and Citizenship website has some examples of biographies for students to
look at.
Using the Biography Organiser template students will find and record information about Amelia Earhart.
Alternatively, students may want to choose a person in Australian history to focus their biographical writing.
Some possible areas of research include:
• Where was Amelia Earhart from? Locate using Google
Maps.
• When was she born? Describe her family life growing up.
• What are some of Amelia Earhart’s achievements?
Choose one to explore in more detail.
• What were some of the challenges she faced?
• How has Amelia Earhart made an impact on people’s
lives?
• What do you admire about Amelia Earhart?
• Sketch a portrait of Amelia Earhart. Explore and
experiment with different techniques and media to
produce a portrait.
Further investigation
• Imagine you could sit down and talk to Amelia Earhart.
What questions would you ask about her life and
achievements?
Journal writing
Students will imagine they are Amelia Earhart before she is about
to set off on her solo flight across the Atlantic Ocean. Students will
write a journal describing their feelings before the expedition.
Students will need to think about language and the era in which
they are writing.
• Explain why you chose to fly solo across the Atlantic
Ocean.
• How do feel?
• What are some of the challenges or dangers?
• What do you hope the expedition will achieve?
Students will reflect on their learning during this activity and respond to the following questions.
• How did you feel about this activity?
• How do primary sources (for example photos, letters, diaries and official documents) help you
understand what might have happened at a place in time?
©ABC 2018
Inquiry
Discuss the story as a class and ask students to pose questions about Amelia Earhart, her achievements
and the mystery of her disappearance. Students will develop an appropriate question to guide an inquiry
about Amelia Earhart (below are some example key questions). Alternatively, students may want to choose
an event or person in Australian history to investigate and focus their inquiry.
• What inspired Amelia Earhart to fly solo across the Atlantic Ocean?
• Why are scientists investigating Amelia’s Earhart’s disappearance?
• Why is it important to investigate the disappearance of Amelia Earhart?
• How has Amelia Earhart’s achievements inspired others?
• How did Amelia Earhart improve women’s rights?
Students will collect and record information from a wide variety of primary and secondary sources and
present the information they find in an interesting way.
• Primary sources – Through using primary sources, that is a document like a diary, paintings or a
physical object such as stone tools, that was written or created at a particular time, we can gain
an understanding of what might have happened at a place in time.
• Secondary sources – Secondary sources are documents written after an event has occurred,
providing “second-hand” accounts of that event, person, or topic. Unlike primary sources, which
provide first-hand accounts, secondary sources offer different perspectives, analysis, and
conclusions of those accounts.
As part of their research, students will need to:
• Use appropriate terms and concepts in their presentation and refer to evidence and
sources.
• Write down the name of the source of the information.
• Look for facts and opinions that answer their inquiry question/s.
• Write down using their own words facts and opinions from the source.

BTN: Episode 7 Transcript 20/3/18
Hey, Amelia here. Thanks for joining me for another ep of BTN.
Coming up today.
• We look back at the life of a famous scientist who showed us the universe.
• In part 2 of our population series, we travel into the future to find out if big is actually good.
• And how do planes work? We sent Matt out to pretend to fly one to find out.
US Tariffs
Reporter: Matt Holbrook
INTRO: You can see Matt not fly a plane later. But first. We're heading to the US where President
Donald Trump got the whole world talking about tariffs recently. He announced a new one on steel
and aluminium imports. But it got a lot of people worried. Here's the story.
These guys are best friends.
FRIENDS: Best friends.
Well, kind of. They do everything together.
FRIENDS: Some things.
Share stuff, play battleship, and pose for the camera. You know, the usual. They're just like these
famous best friends, really. Although their relationship is less about sharing food, and more about
sharing exports. Less playing battleship and more actual battleships. And, well the photos thing is
fairly spot on. The point is, they're close. But recently, US President, Donald Trump, announced
he's introducing a new tariff on steel and aluminium.
DONALD TRUMP, US PRESIDENT: We're going to be instituting tariffs.
And that made some people in Australia question how close these friends really are. Let me
explain. A tariff is an additional cost charged on certain goods that come in from another country.
And it got many Aussies really worried about how it would affect them. 500 million dollars’ worth of
America's steel and aluminium comes from Australia. While that's a pretty small fraction of its 60
billion-dollar annual imports, it's a big deal for the Australian companies that make it.
STEVEN CIOBO, MINISTER FOR TRADE: The imposition of a tariff like this will do nothing other
than distort trade, and ultimately, we believe will lead to a loss of jobs.
Donald Trump says he's doing it to support American industries. See, America's steel and
aluminium industries are struggling right now, because both things can be made cheaper
overseas. So, by forcing countries to pay more to send their goods there, American steel and
©ABC 2018
aluminium seems cheaper by comparison. That keeps more money in the country, and supports
local businesses.
There can be downsides, though. Tariffs can mean higher prices for customers, and if you start
imposing tariffs on other countries, those countries might hit back and apply tariffs of their own. So,
trade can quickly get a lot messier, and more expensive, for everyone. That's why many countries
have trade agreements, allowing trade with each other without being slugged with extra costs.
Luckily, in this case, we later got a reprieve because of our friendship, including trade history, and
our defence partnerships (that's the battleship reference). Donald Trump announced Australia
won't have to pay anything extra to export its steel and aluminium after all.
DONALD TRUMP, US PRESIDENT: We have a very close relationship with Australia. We have a
trade surplus with Australia - great country; long-term partner. We'll be doing something with them.
But while being best friends can come with some perks, it's not so fun for those left out of the deal.
Stephen Hawking
Reporter: Jack Evans
INTRO: World-famous scientist Stephen Hawking has died at the age of 76. He was a pioneer in
cosmology and theoretical physics. Here's how he made such a big impact on the world.
He was often called the most brilliant theoretical physicist since Albert Einstein. Known for his
ground-breaking theories that changed the way we think about the universe and even time itself.
But Stephen Hawking's amazing career actually started as a young man who struggled to get
around to doing his homework. That was the word around Oxford University where he studied
physics. That's the examination of all matter and the forces that interact with it. He then went on to
Cambridge to research cosmology, the study of the origin of universe.
But when he was 21 Hawking's life hit a big hurdle. He was diagnosed with Motor Neurone
Disease. Which causes the brain to stop sending messages to a person's muscles. At the time,
doctors said he would only live for around 2 years, but he proved them very, very wrong.
STEPHEN HAWKING: However difficult life may seem there is always something you can do and
succeed at.
And with the help of a special wheelchair and speech computer that's exactly what he did. Hawking
spent much of his time researching the beginning of the universe and black holes. His most
famous discovery was probably when he demonstrated that black holes emit some radiation.
Before this it was believed that nothing could escape their gravitational pull. The radiation from
black holes has since become known as Hawking Radiation. He also spent a lot of time thinking
about what existed before the big bang. Which sounds pretty complicated right? But Hawking
wrote books that explained his big ideas in ways that could be understood by the average person.
In 1988 he published 'A Brief History of Time'. Which became really popular and sold more than 10
million copies.
But he wasn't just known for his books. He also had a lot of fun becoming a regular on TV screens
around the world. He featured in shows like the Big Bang Theory. And came to life as an animated
character on Futurama and The Simpsons. He even had a big Hollywood film made about his life.
©ABC 2018
Throughout his life Stephen Hawking inspired people to look beyond our planet and expand our
knowledge of the universe. His family says that he'll be greatly missed but the legacy of his
amazing ideas will live on.

Australia’s Population Future
Reporter: Jack Evans
INTRO: Okay. It's time for the second part of our special on Australia's population. Last week we
looked back at our journey to 24 million. Now we're looking ahead to see how big our population
could get and whether we're really ready for it.
Did you know that every 104 seconds a baby is born in Australia? Or that in 2017, 169,993 people
moved here from all over the world? While that might mean a lot more potential friends in the
future. It also means we need to start thinking about how we're going to prepare for all these extra
people.
In just one year, Australia's population has grown by nearly 400,000 people. That's like adding an
extra Canberra annually. Most of them are moving to our major cities. By 2050 Melbourne's
population, for example, is expected to nearly double to 8 million people. There are some benefits
to having more people in the country and it’s not just lots of potential new friends. More people
means more businesses; more buildings means more jobs; and more people paying taxes. But it
might also mean more issues ahead.
For starters, experts say we're going to need better public transport and fewer cars if we want to
stop the main roads of the future looking like this. That means construction of better rail networks
and more efficient roads especially in big cities like Sydney and Melbourne.
PROFESSOR PETER MCDONALD, UNIVERSITY OF MELBOURNE: We haven't done well with
transport infrastructure for a long, long time. Other cities in the world have great metro systems
that move people around really, really well. They have very fast trains between the big cities. We're
still back in the 19th century in this regard.
Transport's not the only thing that's going to feel the pressure either. More and more families are
currently moving to our capital cities. That means we're going to need more schools.
JAMES MERLINO, MINISTER FOR EDUCATION, VICTORIA: We need to accommodate in
Victoria, 90,000 additional students over the next five years, just incredible enrolment growth. So,
we've got 56 new schools in the construction pipeline, 11 of which are opening for the 2018 school
year. But we just need to keep that pace up, year after year, because the enrolment growth, the
birth rate, interstate migration, this pressure is not going to stop.
But with limited space schools are going to have to be built more like this. But education and
transport aren't the only potential problem areas. Experts say healthcare, housing, the environment
©ABC 2018
and vital resources like water could all feel the pinch as the country grows. That's why some
people reckon we should keep Australia's population around the size it is now. It's pretty hard to
limit how many babies are born though. So, they suggest limiting the number of people Australia
takes from overseas instead.
Other people say we should embrace a bigger Australia and all the benefits that come with it. And
instead get started fixing all of the potential problems before they happen. In the meantime,
though, it's clear we're all going to have to get used to sharing a bit more of our country and
possibly our cake.

Amelia Earhart
Reporter: Ruby Cornish
INTRO: Some bones discovered on an island in the Pacific in 1940 are likely those of Amelia
Earhart according to new research. She was a legendary aviator that disappeared while attempting
to fly around the world. Next up, we'll take a look at her life. Then Matt will find out how the planes
she loved so much actually work.
It's one of the world's greatest mysteries. In July 1937, intrepid pilot Amelia Earhart set out on what
she hoped would be her first solo flight around the world, but she disappeared. There are lots of
theories about what actually happened and we'll get to those. First, let's see where her amazing
story began.
Amelia grew up in America in the early 1900s. She hadn't always been interested in planes, but
when she was about 23 she had her first ride in one and she made up her mind then and there to
become a pilot. In fact, she wrote in her diary at the time "by the time I got two or three hundred
feet off the ground, I knew I had to fly." In those days, women didn't have the same rights as men.
They'd only just won the right to vote, and the idea of a woman piloting planes was pretty out there.
But Amelia wasn't fazed. She began flying lessons, and a few years later became the 16th woman
in America to get her pilot license.
In 1928, she became the first woman ever to fly solo across the Atlantic Ocean. The trip lasted
nearly 15 hours and she had to contend with strong winds, icy conditions and a bunch of
mechanical problems along the way. And Amelia's achievements didn't stop there. Before long she
found herself a major celebrity. She kept breaking flight records, became a best-selling writer, and
an activist for women's rights. In July 1937, she set off on her attempt to fly all the way around the
globe. but on her longest leg of the journey, somewhere over the Pacific Ocean, her radio
messages stopped and that was the last anyone heard from her.
Many people believe her plane crashed and still lies somewhere on the ocean floor, but there is
another theory too. In the 1940s, builders discovered some bones on the tiny Nikumaroro Island,
that’s right here in the South Pacific Ocean and about 650 kilometres from where Amelia was
meant to land. But experts who studied the bones at the time decided they actually belonged to a
man.
Fast forward to today and those bones are long lost. But an American professor decided to revisit
the case anyway. He used a pair of Amelia's pants to figure out her measurements and used a
photograph of her holding a can of oil to estimate the length of her arm bones. His verdict? He
thinks the bones are a likely match.
So, has the Amelia Earhart mystery been finally solved? We can't be sure, and we probably won't
ever know with 100 per cent certainty. But what we do know is that no matter what happened on
her final trip, Amelia is still inspiring little girls to have some very big dreams.

Amelia Earhart bought her first plane within six months of her first flying lesson.
She paid $2000 for it and nicknamed it 'The Canary' because it was yellow.
How do planes fly?
Reporter: Matthew Holbrook
INTRO: Hi BTN, my name is Jana, and I'm Charlotte. And our question is: How do planes
mechanically fly?
Aeroplanes, they're the big heavy hunks of metal taking over our skies.
MATT HOLBROOK, REPORTER: Someone should do something about them.
JACK: Something like celebrate their wonderous ability to defy gravity while taking us places
quickly and conveniently?
MATT: Oh Yeah.
Anyway, I've come to a place that does just that: The South Australian Aviation Museum. Where
better to understand how planes fly, than a place showcasing how flight technology has changed
and improved over time? I'm getting some expert help, from volunteer, John.
MATT: Tell us about this.
JOHN ROBERTS, VOLUNTEER: This is a Mark V, Spitfire 1943. It was pretty fast in its time.
MATT: So, John, how do planes like this one actually fly?
JOHN: It's the airflow going over the top of the wing and underneath the wing. Because of the
forward motion, and you increase as the engine goes, and takes you faster forward, this wing will
actually lift up.
Wings make lift by changing the direction and pressure of the air crashing into it. These wings have
a curved upper surface and a flatter lower surface. The curved upper part of the wing lowers the air
pressure directly above it, and the lower part of the wing increases it, helping to generate lift. There
are a few other forces going on, too. Importantly, thrust from the engine, which sends a plane
forwards. There's the resistance of the air as the plane moves through it, that's called drag. And
there's weight. You need more lift, than the weight of the plane to move it upwards into the sky.
The Spitfire may have been fast for its time, but John tells me it's got nothing on the F111, used by
the Australian Air Force up until 2010.
MATT: This is enormous, John, it must have some serious power going on behind it to make it go.
JOHN: You're quite correct there, Matt, there are two engines inside this aircraft. It actually flies at
2,500 kilometres per hour. If you put that into perspective, you can fly from Adelaide to Melbourne
in 12 minutes. Now that's fast.

MATT: That is fast. Should we go do it, then?
JOHN: Sounds good.
MATT: This is slightly overwhelming John, what am I supposed to do now?
JOHN: It's very impressive, isn't it, Matt? You have the joystick for flying, and that will take you in
any direction you wish. You are the captain.
MATT: I'm the captain?
JOHN: You are the captain.
MATT: Well, we're not going anywhere, I can tell you that much.
JOHN: And this young chap here who will eventually sit there is the weapons co-ordinator, he
looks after all the armament, that type of thing.
After brushing with supersonic speeds, I'm going back to flight school.
MATT: John, can you tell me what this is all about, this looks like fun!
JOHN: This was what was used in the fifties to see if any pilot or human being, male or female,
had any co-ordination to the limbs to the brain. The idea is to keep that light to the middle there for
two and a half minutes. If you could do that, you became or entered to become a pilot. So, there
you go, Matt, prove your point, you should be a pilot and not a TV host.
MATT: I thought this would be fairly easy, and it's not.
Not exactly reassuring, but I definitely have a newfound appreciation for these magnificent
machines and the people who fly them.
