Hello everyone.

My name is Mrs. Mehrin, and I'm so excited to be learning all about the impact of smoking with you.

Let's begin.

Welcome to today's lesson from the unit Keeping Healthy.

Your lesson outcome today is I can describe the impact of smoking, including vaping, on the human body.

Now, I know that learning can sometimes be a little bit challenging, but that's okay because it just means that we are going to work really hard together and we are going to learn lots of fabulous new things.

So here are your five key words for today's lesson.

Now next to the key words, you have your definition as well.

I am going to be referring to all of these throughout today's lesson.

However, if you find it helpful, you can pause the video now and jot these down.

Fabulous.

Well done.

So let's begin with the first part of your learning today, which is smoking and vaping.

Sam and Alex have seen people smoking and vaping in their local community and want to know more about it.

Sam says, "I think the smoke from cigarette smells really bad.

Why do people smoke?" And Alex says, "I don't think vaping smells bad.

Is it a healthy way of smoking?" What questions do you have about smoking and vaping? I'll give you five seconds to think about any questions.

Off you go.

Now, tobacco is a type of plant that is dried and smoked in cigarettes, pipes, or cigars, and cigarettes can be purchased ready-made or rolled using to tobacco and cigarette paper, just like in this picture here.

Now, tobacco contains a substance called nicotine, which is a highly addictive drug.

This means once somebody starts smoking, it's very difficult to stop because their body craves more nicotine.

And to help prevent young people from becoming addicted, there are age limits on buying products containing nicotine.

It is illegal to buy these products below a certain age.

Now, why is it so difficult for people to stop smoking once they have formed the habit? Is it because, A, they think smoking is good for their health, B, they don't think there is any reason to stop, or C, they are addicted to the nicotine in cigarettes? I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

The answer is C.

Now, as well as nicotine, there are over 5,000 other substances inhaled when smoking a cigarette, many of which are harmful.

People who are in the same area as others who are smoking can also be harmed by breathing in the smoke that is produced from a cigarette in the air around them.

This is called secondhand smoking.

Now, vaping is the inhaling of a vapour produced by an electronic cigarette, also known as e-cigarettes or vape pens.

I've got a picture here of some e-cigarettes, and you can see they come in all shapes and sizes.

So e-cigarettes come in different forms, including some that look like ordinary cigarettes and some that look like pens or USB sticks.

The vapour in e-cigarettes contains nicotine, as well as other substances that give the vapour different flavours or sense.

This means that vaping can be just as addictive as smoking.

Now, which of these do smoking and vaping have in common? A, they both contain nicotine, B, they both use battery powered devices, C, they both use tobacco leaves rolled in paper, or D, they can both be addictive.

I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

The answers are A and D.

Now here is your first task for today.

It says, are these statements correct or incorrect? So here are the statements.

So you've got, in the UK, children can legally buy products containing nicotine.

B, smoking is addictive because tobacco contains a drug called nicotine.

C, vaping is not addictive like smoking is.

And D, e-cigarettes and vape pens are types of equipment used for vaping.

Now along the top, you have got these sentences here, so you need to match those statements to these sentences.

I am sure this is correct.

I think this is correct.

I think this is incorrect.

I am sure this is incorrect.

So I'd like you to pause the video here and have a go at doing this activity.

Off you go.

Fantastic.

Well done.

So you could've had, for A, you could've had, I think this is incorrect, I am sure this is incorrect.

For B, you could've had, I am sure this is correct, I think this is correct.

For C, you could've had, I think this is incorrect, I am sure this is incorrect.

And D, you can have, I am sure this is correct, I think this is correct.

Now the second task says rewrite these incorrect statements so they are correct.

In the UK, children can legally buy containing nicotine.

B vaping is not addictive like smoking is.

So again, I'd like you to pause the video here and have a go at rewriting these incorrect statements.

Off you go.

So you would've rewritten it to.

It is illegal for children to buy products containing nicotine, and many e-cigarettes and vape pens contain nicotine, so vaping is just as addictive as smoking.

Now we are onto the second part of your learning today, which is how smoking and vaping affect the body.

So decades ago, cigarettes were marketed as having some health benefits such as reducing stress.

So here we have some adverts, newspaper adverts from 1939, which shows a doctor and an athlete endorsing a brand of cigarettes.

So the doctor is saying, "From personal experience, I prescribe Piccadilly for cool, clean smoking." And the athlete here says, "As a champion on the ice, I choose the champion cigarette, Piccadilly, of course." So why do you think we don't see adverts like this now? I'll give you five seconds to think about your answer.

Fabulous.

Well done.

So now we are much more aware of the harmful impact that smoking has on our health, and scientists have gathered lots evidence from inquiries that show both the short-term and long-term effects that smoking has on our bodies.

We also now have regulations in place that stop companies from advertising products in a misleading way.

So what that means is that they can't lie about the product that they're selling and make it seem good if it's not.

Now, what do you know already about the harmful effects of smoking? I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

So nicotine causes an increase in heart rate and blood pressure, making the heart work harder.

It also causes the arteries to become narrower, making it harder for blood to be pumped around the body.

This means it's more difficult for oxygen to be delivered to different parts of the body to help it to function.

Now let's do a quick check-in of your learning, It says smoking makes it something for blood to move around the body and deliver oxygen where it's needed.

Is the answer A, easier, B, harder, C, simpler, or D quicker? I'll give you five seconds to think about your answer.

Off you go.

Fabulous, the answer is harder.

Smoking makes it harder for blood to move around the body and deliver oxygen where it's needed.

Now, nicotine changes the way the brain works and is especially harmful to young people whose brains are still developing, and it can cause problems with attention, learning, and your mood.

Now, many of the harmful substances are inhaled when smoking.

So tar for example, which is found in tobacco, collects in the lungs as a sticky brown substance when it's inhaled, And tar makes it harder for the lungs to do their job of absorbing oxygen from the air we breathe in.

And over time, the tar inhaled from smoking tobacco can cause significant and permanent damage to the lungs, and we can see that here in this picture where you can see the smoke damage, you can see how black it's become, and that is from smoking.

Now, over 5,000 other substances are inhaled when smoking a cigarette, many of them which are harmful.

So carbon monoxide is a poisonous gas which stops the blood from carrying as much oxygen as it should.

An arsenic is a poison which causes digestive problems and can lead to a number of diseases.

Now, the impact of smoking on the heart and lungs means that being active becomes much harder for smokers.

So they become more easily worn out from activities, like walking upstairs or carrying shopping, and it can make it harder to keep up with friends who don't smoke when playing active games like football, even just breathing deeply can become more difficult for long-time smokers.

Now, smoking can cause illnesses, including heart disease and lung disease.

It can reduce life expectancy by an average of 10 years.

Smoking can discolour teeth and lead to gum disease, which is the leading cause of tooth loss, and we can see here this person has discoloured teeth from smoking.

Now let's do a quick check-in of your learning.

It says smoking can cause, A, an improvement in fitness level, B, better mental health and wellbeing, or C, a number of diseases, including heart and lung disease.

I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

It's C, a number of diseases, including heart and lung disease.

Now, Lucas says, "There is no tar and far fewer substances in the vapour that is inhaled when vaping compared to smoking tobacco." Alex says, "Does that mean vaping is better for you than smoking?" What do you think? I'll give you five seconds to think about your answer.

Off you go.

Fabulous, well done.

So fewer substances are inhaled through vaping than when smoking tobacco, but it is still not completely safe.

The vapour that is inhaled still contains nicotine and can negatively impact heart and brain development.

Vaping is also a relatively new invention, so scientists are not yet aware of the long-term effects of vaping on the body.

Now let's do a quick true or false.

Vaping is a completely safe alternative to smoking.

Is that true or false? I'll give you five seconds to think about your answer.

Fantastic.

The answer is false.

Now let's see if you can justify your answers.

It's because, A, fewer chemicals are inhaled through vaping, but they can still be harmful to our health, or, B, vaping is considered to be much more dangerous than smoking.

Again, I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

The answer is A.

Now, Alex would like to find out more about the impact of smoking and vaping on health.

And he says he knows he can carry out some research using secondary sources of information, but he's not sure which will be the most reliable.

Alex says, "Which of these sources of information do you think will be reliable?" A, a blog on a heart disease charity website, a social media post about one person's experience of smoking, an article in a science magazine for young people, a blog post on a website selling different flavours of vapes.

So which of these sources of information do you think will be most reliable? I'll give you five seconds to think about your answer.

Fantastic.

Well done.

So to help decide if a source is reliable, think about how the information has been gathered and what data was used.

So social media post about someone's personal experience has only drawn on data from one person, and so it's not very helpful information.

Also think about the reason the source has been written.

So information on a website for selling vaping accessories is likely to downplay the negative effects of vaping because the company won't want to discourage people from buying them.

Alex says, "I'm going to use the blog from the heart disease charity website and an article in a science magazine for my research.

I can see that they have used data from a range of scientific inquiries and have been written with the intention of helping people to make healthy choices." Now let's do a quick check-in of your learning.

It says, we can find out more about the impact of smoking and vaping by, A, carrying out research using secondary sources, B, carrying out a fair test investigation, or C, trying out smoking and vaping for ourselves.

I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

The answer is A, carrying out research using secondary sources.

Now, here is your second task for today.

It says use the secondary sources included with this lesson to carry out research like Alex, and complete the table.

So we've got the body parts.

We've got the circulatory system, the lungs, the skin, and the teeth.

And you need to write what the effects of smoking are and what the effects of vaping are.

So I'd like you to pause the video here and have a go at doing this activity.

Off you go.

Fantastic.

Well done.

So, with the circulatory system, effects of smoking is damage to blood vessels, which increases the risk of heart disease and stroke, and the effects of vaping is it causes arteries to become narrower.

In the lungs, there's a buildup of tar which causes permanent damage and makes it harder to breathe and can lead to lung disease, and that's with smoking.

And the effects of vaping is it makes it harder to breathe and could lead to lung disease.

For the skin, the effects of smoking is it causes premature wrinkles.

So that means that you get wrinkles earlier than you would if you were not smoking.

And the effects of vaping is that it causes skin to be dry and you are prone to more wrinkling.

The effects of smoking on your teeth, it causes gum disease, tooth loss, bad breath, and yellow teeth.

And the effects of vaping on the teeth is it causes gum disease, tooth decay, and bad breath.

So now we are on to the summary of our learning today.

Smoking and vaping involve the inhalation of nicotine and other substances.

There are a number of negative effects on health associated with smoking, including damage to the heart and lungs and increased risk of disease.

Vaping is considered to be less harmful than smoking, but it's still not completely safe and we do not yet know about the long-term impact of vaping on health.

Information about the dangers of smoking and vaping can be researched using secondary sources of information.

You have worked really, really hard this lesson.

I'm so proud of you.

Well done.
