Teen obesity Please consider the sensitive nature of this topic when discussing the issue of

obesity with students.

Students will be investigating solutions to the teenage obesity problem in

Australia. Begin with a class discussion focussing on the following questions:

What is obesity?

What are the contributing factors to teenage obesity? Factors such as

changes to diet (more fast food/convenience food), changes in lifestyle

(busy, less time for exercise), advertising fast food that is directed at young

people.

What are the factors influencing food choice? (Consider cultural/family

background, personal likes/dislikes, money available, time available for

shopping and food preparation.)

Who is responsible for tackling the problem? Why?

How can we get the message through? Working in pairs or small groups, students will create a public education campaign

to address the issue of obesity. Discuss with students different approaches that

could be taken about the issue. Here are some examples:

Who will you target for the campaign – kids, adults or both?

What approach will you use? Consider creating a cartoon/animation, using

celebrities or humour to get the message across or shock tactics (think

about the anti-smoking campaigns).

Include a logo, jingle or gimmick to help get the message across.

Understand how a satellite stays in orbit by completing the following task:

Put a tennis ball inside one leg of a pair of stockings. Hold the end of the

stocking and whirl the ball over your head. The ball is held in its `orbit’

around your head by the stocking, which is similar to the force of gravity

that pulls satellites toward the Earth. If the `gravity’ of the stocking were

not acting on the ball, the ball would continue in one direction.

Research what happens to satellites when they stop working. Are they

repaired in orbit, brought back to Earth to be repaired or recycled, or left

in space? What are the potential hazards?

On this week's Behind the News:

Growing problem: Why obesity in kids is causing concern.

Driven to distraction: Should hands-free mobile phones be

banned from cars?

And pictures from above: We learn more about satellites.

Hi I'm Nathan Bazley, welcome to Behind the News.

Also on the show today, Tash gets hooked on fishing and finds out it's

more than just a hobby.

But first to a shocking report about kids health.

Teen Obesity

Reporter: Kirsty Bennett

INTRO: It's no secret that eating fruit and veg and exercising is the

key to a healthy body.

But it seems like lots of Aussie kids just aren't getting the message.

A new study has come out that shows obesity could end the lives of

teens much sooner.

Page 8: Questions for discussion - ABC...Questions for discussion Teen obesity 1. Briefly summarise the main issues raised in the Teen obesity story.2. What did a recent national survey find

Here's Kirsty

KIRSTY BENNETT, REPORTER: A war between junk food and fruit

and veg is on. In the computer world and in the real world, it seems

like fruit and veg just can't compete. A national survey of 12,000

Aussie teenagers has found that kids aren't taking good care of their

health. It's the biggest piece of research that's been done on teens for

about 25 years.

And it found that the Aussie diet is a recipe for disaster. One in four

kids are overweight or obese. They drink four or more cups of sweet

drinks a week. Half of them have a TV in their bedroom and most

have at least three in their house, so let's put in some TV snacks. So to

get rid of all this, they need to exercise, but according to the study that

isn't happening. So when this is all mixed together the result isn't

pretty.

Health experts warn that this mix could lead to health problems like

diabetes, cancer and heart disease. Heart disease is the biggest killer

in Australia, so what is it?

Your heart works like a pump, moving blood around the body. The

heart itself needs a blood supply but if the arteries supplying it get

blocked, then you're in trouble. Too much bad food can cause them to

get blocked up with stuff called plaque. This narrows the arteries and

makes it harder for the blood and oxygen to flow to the heart muscle.

Without oxygen, part of the heart muscle begins to die and that can

lead to a heart attack.

Experts have looked at the diet and lifestyle habits of kids in the new

survey. And they reckon that it all points to one thing: that this

generation could die earlier. So how did kids get to this point?

There are a few things involved. Kids used to walk to school every day,

but now, many are driven. And more time's spent playing with

technology than playing a sport. The average Aussie kid watches

around a dozen junk food ads a day and according to the new survey,

half said they'd tried a new food in the past month because of an ad.

Page 9: Questions for discussion - ABC...Questions for discussion Teen obesity 1. Briefly summarise the main issues raised in the Teen obesity story.2. What did a recent national survey find

A quarter said they sometimes bought fast food because of a special

offer like a free toy. So, who's responsible for tackling the weight

problem?

JOSH, STUDENT: My family and my friends could give me advice.

KUSINI, STUDENT: Myself, my parents, my family.

MARISA, STUDENT: Because so I learn what I should put in my

lunchbox so when I get older I know what to feed my family.

REPORTER: Some people think the government should step in and

ban junk food ads from TV at times when kids might be watching. But

it's not like governments aren't doing anything. They've spent millions

on a whole load of different schemes to tackle obesity ranging from

breakfast clubs in poor communities to taking parents around

supermarkets to teach them about healthy eating. In school, there

have been some changes too like offering healthier options in

canteens. But when pies and pizzas are available, they're usually the

most popular things with kids.

So perhaps it's time for you to choose the healthy option, otherwise it

could be game over.

Presenter: After that I think we need a very healthy quiz!

Quiz 1

Which of the following foods contains the most vitamin C?

Capsicum

Oranges

Page 10: Questions for discussion - ABC...Questions for discussion Teen obesity 1. Briefly summarise the main issues raised in the Teen obesity story.2. What did a recent national survey find

Strawberries

Answer: Capsicum

Particularly red capsicum which actually contains around 4 times

more vitamin C than strawberries and oranges.

OK, let's get on with some more of the week's news now in the wire.

The Wire

After 18 days of massive protests in Egypt, Hosni Mubarak has

stepped down as president.

The military is now in charge, and will govern for six months or until

elections take place.

But some protesters said they still weren't happy with the plan.

**********

Back home and a special health reform deal has been signed.

After an 8 hour meeting yesterday, state and territory leaders told

Prime Minister Julia Gillard they would support a plan to change the

way hospitals are funded.

Page 11: Questions for discussion - ABC...Questions for discussion Teen obesity 1. Briefly summarise the main issues raised in the Teen obesity story.2. What did a recent national survey find

In the future state governments and the federal government will put

money into one national funding pool to pay for the health system.

The funds will then be paid out to the states and territories depending

on how many medical procedures they perform.

The deal also means the Federal Government will give another 16

billion dollars to hospitals over 10 years.

Disaster Insurance

Reporter: Nathan Bazley

INTRO: Both Queensland and Victoria are still cleaning up after big

flooding disasters there but something is making some people very

angry as they start to rebuild.

When the waters in both states swept through thousands of homes

most owners relied on the thought that their homes were insured so

they'd be able to afford to start again.

But when they went to claim many found that there was bad news in

store.

Let's find out more about insurance and why it always pays to read

the small print.

NATHAN BAZLEY, REPORTER: What do David Beckham's feet,

Jennifer Lopez's bottom, Heidi Klum's legs and Fernando Alonso's

thumbs all have in common?

They've all been insured against damage; some for tens of millions of

dollars!

Page 12: Questions for discussion - ABC...Questions for discussion Teen obesity 1. Briefly summarise the main issues raised in the Teen obesity story.2. What did a recent national survey find

But it's not just stars who take out insurance; there is a good chance

your parents have some too; although probably on something more

normal, like your house.

And it's just this type of insurance that's been hitting the headlines

over the last few weeks.

Before we look at that though, let's work out exactly what insurance

is.

Say you have something that would be expensive for you to replace if

it was damaged - like your laptop.

You can insure it!

First, they'll ask what you want it insured against.

KID: Well I want it to be replaced if I drop it and break it and if I get

caught in the rain and it gets wet.

Then they calculate the premium, which is the amount they'll charge

you each month to keep your laptop insured.

The insurance company decides how likely it is that you could damage

your laptop, so if things happen to them a lot, you'll end up paying

more money on your premium.

Finally, you sign your policy and now your laptop is protected!

If something goes wrong, you just make a claim and as long as it's

covered in your policy, you'll get the money to buy a new one!

But what if something goes wrong that isn't listed?

Page 13: Questions for discussion - ABC...Questions for discussion Teen obesity 1. Briefly summarise the main issues raised in the Teen obesity story.2. What did a recent national survey find

KID: My computer has been water damaged. I dropped a glass of

water on it.

INSURANCE: Sorry, you're not covered. Your policy says that you're

only covered if it get's rained on.

Unfortunately, a similar situation is happening in Queensland after

the flooding there last month.

IPSWICH RESIDENT: We're all in the same boat. It's all different

companies - people thinking they're insured but they ring up and find

out they're not.

The problem comes from the definition insurance companies use for a

flood.

They break it up into two main types. There is flash flooding, which is

caused by rapidly falling rain and there is riverine flooding, when

rivers rise as lots of water flows down them.

Unfortunately, many homes were only covered for flash flooding. But

the majority of damage in Queensland was through riverine flooding,

meaning thousands would get no help.

IPSWICH RESIDENT: A flood is a flood no matter where it comes

from. Either the river rises or it comes out of the sky it's still a flood.

IPSWICH RESIDENT: You hear on the radio about the flood that we

had. We didn't have a flood, we just had a river rising.

Victorians have also been hit after the flooding there.

Many are now calling for just one definition of a flood, so it doesn't

matter how the flooding happens, if it's listed then you're covered.

Page 14: Questions for discussion - ABC...Questions for discussion Teen obesity 1. Briefly summarise the main issues raised in the Teen obesity story.2. What did a recent national survey find

But insurance companies say the definitions have always been

available to their customers, many just don't bother checking.

JULIA GILLARD: My message to insurance companies, is to show the

same spirit as the people of QLD have been showing, as they've pulled

together in these very difficult circumstances.

The fight between flood victims and insurance groups will go on for a

while, but hopefully the headlines surrounding this issue will warn

others to check before the next disaster strikes.

Mobile Driving

Reporter: Natasha Thiele

INTRO: Using a mobile phone while driving is against the law and

now politicians are thinking about banning hands-free devices too to

make our roads safer.

But for some businesses taking calls from customers on the road is

part of their job.

So what would it mean for them if a ban was in place?

Tash went to find out

NATASHA THIELE, REPORTER: Lots of people depend on using

mobiles phones to run their business, like Simon.

He's an electrician so he's always on the run.

And customers rely on him to answer their call, otherwise they'll go

elsewhere!

Page 15: Questions for discussion - ABC...Questions for discussion Teen obesity 1. Briefly summarise the main issues raised in the Teen obesity story.2. What did a recent national survey find

SIMON, ELECTRICIAN: It's okay when you're at a job, but you're

often in a van and it's your office sort of during the day, so that's the

time to make calls back to people or sometimes receive calls.

But this electrician's mobile office could soon be about to short-

circuit.

Transport experts from around the country want to cut down the

number of deaths on our roads over the next 10 years.

So they've come up with a road safety report and part of that suggests

going further than the current ban on mobile phones. They want

hands free devices banned too!

A hands-free device can be something like this bluetooth piece.

You don't need to physically hold your phone, it uses wireless

technology in your car or through an ear piece!

They're supposed to stop drivers from touching their phone while

driving, but the report says hands-free kits can still lead to accidents.

Each State and Territory has different laws when it comes to using

mobiles in the car.

Some won't even allow you to touch your phone to answer a call; it

needs to be on a special mount.

Well, I thought I'd test the hands-free theory out for myself by

heading to a driving training centre.

And I had driving instructor Marg watching over me!

Page 16: Questions for discussion - ABC...Questions for discussion Teen obesity 1. Briefly summarise the main issues raised in the Teen obesity story.2. What did a recent national survey find

But let's see if I was distracted when I got a call on the hands-free.

REPORTER: So Marg, how did I go?

MARG PEARCE, DRIVING INSTRUCTOR: Well you certainly did so

much better when you weren't on the mobile phone. When the phone

rang, it was definitely a distraction. I noticed you had your hands

inside the steering wheel a lot more and also you were also

considerably slower going through the cones and of course you

almost collected a couple of the cones. So definitely much better

without the phone.

Some people argue that there are many distractions in a car and that

hands-free mobile phones are being unfairly targeted.

REPORTER: There's putting on make-up, having a sip of coffee,

changing the CD and really annoying people in the back!

REPORTER: Can you guys keep it down!

Some question that if there was to be a ban on hands-free kits, then

why wouldn't these distractions be taken into account too?

Well, that's because with driving, there always has to be some risk

involved.

It's not possible to take out all the danger, otherwise speed limits

might as well come down to walking pace.

So, there's often a balancing act between making roads safer and

being realistic about how people use their cars.

A ban on hands-free kits would be hard for people like Simon who

rely on it so much and experts also think it would be hard for police to

check if people are following the rules.

Page 17: Questions for discussion - ABC...Questions for discussion Teen obesity 1. Briefly summarise the main issues raised in the Teen obesity story.2. What did a recent national survey find

The first step could be to encourage drivers to stop using them

voluntarily.

But there are lots of different points of view, so it could be some time

before they make a final call.

Presenter: OK that's an issue that's given you a lot to think about.

Let's make it our poll this week.

Online Poll

The question is:

Should drivers be banned from using hands free mobile phones?

Satellites

Reporter: Kirsty Bennett

INTRO: In the program so far, we've talked about mobile phones

and about people coping with extreme weather events.

Well, both of these things rely on satellite technology.

Think back to Cyclone Yasi and you might remember the constant

use of satellite weather pictures to show people where the storm was

heading.

So satellites are really useful but how do they work?

Page 18: Questions for discussion - ABC...Questions for discussion Teen obesity 1. Briefly summarise the main issues raised in the Teen obesity story.2. What did a recent national survey find

Kirsty investigates.

KIRSTY BENNETT, REPORTER: On the ground, this is how people

saw Cyclone Yasi. But before the winds came, all eyes were fixed on a

different type of picture. The view from above undoubtedly helped

many people to prepare for the storm and survive it. So how do we get

these sky-high pictures?

Well, it's all thanks to satellites. There are thousands of them orbiting

the Earth and they do different things. Some receive and send out

signals so we can talk on the phone and watch TV. Even shows like

BtN go through a satellite at some stage before it hits your TV screens.

NATHAN BAZLEY, PRESENTER: Hi I'm Nathan welcome to Behind

the News.

REPORTER: They can help us to navigate our way around in the car.

At the end of the road turn left.

REPORTER: And that same technology can be a vital tool in tracking

down someone who might be lost at sea.

There are spy satellites too but not many people know what they're

looking at because it's top secret!

And as we saw they can give us great pics of what the weather is like

where you are now and what weather systems might be just around

the corner.

So let's look at some of these different satellites. They can be found in

different orbits around Earth. Some sit around 300 kilometres from

the Earth's surface. It might sound far, but it's just like travelling from

Sydney to Canberra. They move constantly around different parts of

Page 19: Questions for discussion - ABC...Questions for discussion Teen obesity 1. Briefly summarise the main issues raised in the Teen obesity story.2. What did a recent national survey find

the earth, taking pictures and sending information. There are also

some even further away called "geostationary" satellites. Their

movement matches the earth's rotation, which means they actually

appear to stay in the same place, which is in line above the equator.

These are used for communications, like satellite TV and mobile

phones.

So if you had a big satellite dish like this one that picks up TV signals,

it has to be on an angle, so this pointy part could get in touch with the

geostationary satellite about 36000 kilometres away in space.

So how do we get satellites up there in the first place?

Satellites are shot up into orbit by a rocket. Once it gets to a certain

distance, speed and trajectory the rocket releases the satellite so it

orbits the earth in the correct position. It depends on absolute

precision.

The weather bureau is one organisation that has come to rely on

satellites. They use ones that are about 850 kilometres above the

Earth, so they can get high quality pictures like this. And remember

those geostationary satellites? They use them too to get a wider

picture of the Earth and the weather patterns. Being able to track the

directions of extreme weather events means they are in a better

position now to make accurate forecasts. And as we've seen in recent

weeks, it can mean the difference between life and death.

PAUL, SENIOR METEOROLOGIST: So we've taken or got a picture

every hour from the satellite we join them together into a loop and

then we can see in this case tropical cyclone Yasi passing across the

Queensland coast.

REPORTER: As people find more uses for satellites, more are being

sent into orbit meaning space could one day resemble a busy car park.

Presenter: OK, let's see how closely you were listening to that story.

Here's a quiz

Quiz 2

The question is:

How high up is a geostationary satellite?

3,600 kms

36,000 kms

360,000 kms

Answer: 36,000 kms

That's about a tenth of the way to the moon.

Now from space to sport. Here's the score.

The Score

To cricket first where Australia have shown some shaky form in a

warm-up match against India in preparation for their world cup

campaign next week.

After dismissing India for a modest total of 215, Australia started off

well cruising to 1 for 118 courtesy of a solid 57 from skipper Ricky

Ponting in his first match back after a broken finger.

But from there things went pear-shaped quickly and the Aussies soon

found themselves all out for 176.

The team will be hoping for better fortunes in their first match against

Zimbabwe if they are to defend their title.

***********

To soccer now where Brisbane Roar has claimed the W-League

championship with a 2-1 victory over reigning champions Sydney FC.

The scores were level at half-time, but substitute Lisa De Vanna

scored the winner midway through the second half.

***********

And finally we have what could easily be the goal of the year in the

English premier league.

Wayne Rooney pulled off this bicycle kick in Manchester United's 2 - 1

win over Man city over the weekend.

And not surprisingly the commentators thought it was pretty good.

The goal kept Manchester United four points clear at the top of the

table.

Fishing

Reporter: Natasha Thiele

INTRO: It's one of the most popular participation sports in Australia

but you're unlikely to find it on the back pages of a newspaper.

And you'd be hard pressed to name the current world champion.

So why is it the sport of fishing so often goes under the radar?

We sent Tash to find out.

NATASHA THIELE, REPORTER: They're world champions, leaders

of their field, top of their sporting tree.

But hang on! Who's this guy?

He's an American called Mike Iaconelli and he's one of the best in the

world in the sport of fishing!

Five million Aussies regularly go fishing. That's more than who play

most other sports like rugby and football.

Like many kids, James enjoys fishing on weekends with his dad.

REPORTER: So what do you like about fishing so much?

JAMES: When you catch a big snapper and it goes zzz and you almost

get pulled off of the boat!

In the past and even for some communities now, fishing has been an

important way to get food.

For others it's a sport, or just something to do for fun with your

mates.

Page 23: Questions for discussion - ABC...Questions for discussion Teen obesity 1. Briefly summarise the main issues raised in the Teen obesity story.2. What did a recent national survey find

JAMES: I was fishing with my friends and this big snapped was on

both of my friends' line and then I said 'why can't I catch a big

snapper' and as soon as I said that this big snapper came on and it

went zzz and it took me 15 minutes to wind up!

REPORTER: Did you get some help winding it up?

JAMES: Nah, I did it all myself because my dad wanted me to.

REPORTER: And how big was it?

JAMES: Pretty big, it was about seven kilos or eight.

James caught the fish on a boat, but there are stacks of different types

of fishing you can do.

There's land-based fishing, like at a jetty or rocks.

Off-shore fishing, that's usually on big boats in the ocean. Often the

fish are bigger so the rod and line need to be extra strong.

And there's fly fishing. That's pretty popular in Tasmania where they

catch trout.

The rod is light-weight and flexible and it takes a lot of skill to master

it.

Fishing can also be a seriously competitive sport, especially in places

like the United States.

Guys like Mike Iaconelli, who you met before, can earn around a

million dollars a year!

Page 24: Questions for discussion - ABC...Questions for discussion Teen obesity 1. Briefly summarise the main issues raised in the Teen obesity story.2. What did a recent national survey find

The rules vary in each tournament.

Sometimes it's about who catches and tags the most fish, in others it's

about who can catch the heaviest fish.

But even if you're fishing for fun there are lots of rules and regulations

you need to follow.

In some states in Australia, adults need to buy a permit to fish in

certain places.

And when you catch a fish, you need to make sure that it's big enough,

otherwise you have to release it back into the water.

That's where these size charts come in. You may have seen them down

at the beach.

There are also limits on how many fish you can take.

The idea is to make sure we're not taking out the young little fish,

before they've had a chance to breed.

That helps the sustainability of our fish population.

So as long everyone sticks to the rules, then kids like James can enjoy

successful fishing trips for many years to come.

But if fishing's going to gain more popularity as a glamorous sport, it's

going to have to compete against other sports that are hooking kids

in!

JAMES: I want to be a football player!
