Lesson video

Hello, my name is Miss Willow, and I'm going to be guiding you through today's learning.

Today's lesson is called, "The Power of Data" And it fits into our unit called, "Media Influence.

Who Decides What I Experience in the online world?" Okay, let's make a start on today's lesson.

By the end of today's lesson, you'll be able to describe how powerful shared data is in the online world.

Before we get started, let's go over some ground rules.

These help to make sure that everyone stays safe and comfortable throughout today's lesson.

Laura says that we need to listen to others.

That means we're not going to interrupt other people if they're speaking.

Andeep says that we need to respect each other's privacy, and that means we're not going to ask anyone any personal questions as this can make some people feel uncomfortable.

Jacob says we need to not have any judgement.

That means we're not going to judge other people for what they think, what they feel, or what they've experienced.

And Izzy says that we need to choose our level of participation.

That means it's up to us how much we want to join in.

We're now going to go through the keywords for today's lesson.

These are gonna come up multiple times throughout today's lesson, so it's really important that we have a good understanding of what each word means.

First of all, we've got data.

Data is detailed information which is stored online.

Personal data is detailed information which is about us, which is stored online.

And advertise.

To advertise means to persuade someone to buy something.

As we go through today's lesson, keep an eye out for these key words and see if you can spot them as they come up.

Today's lesson is split into three learning cycles.

What is data? Why do social media companies want our data and how can we control what happens to our data? We're going to make a start on our first learning cycle.

What is data? When learning about data, it's really important to remember that the internet is a big network, connecting online devices from all around the world.

For example, phones are connected to the internet, and tablets, and laptops too.

All of these devices are connected to the internet.

All the online information from these devices is called data.

And remember, that was one of our keywords from the start of the lesson.

Data is made up of images, videos, files, personal information, websites, and online activity.

All of this makes up data.

This data is stored in servers all over the world.

A server is a powerful machine which sorts information and passes it onto other computers.

In this photo, you can see what a server looks like.

There are lots of them all over the world.

Data is stored on lots of different computers, but typically, the data that you generate, which means create, is held in multiple different locations.

These are often close to where you are.

Let's do the check for understanding to see how you're getting on.

True or false, all data is stored in one server.

What do you think? Pause the video, tell the person next to you, tell me or have a think to yourself.

Well done if you said false, but why? Data is stored in multiple servers all over the world.

Typically, your own data is stored in servers close to where you are.

Well done if you remembered this and said something similar.

Our personal data is detailed information that's stored online.

This usually includes our gender, our age, our interests, so the things that we like, our location, meaning where we are, and the websites that we visited.

All of these make up our personal data, the data that's specific to who we are.

Personal data is specific to who we are, so everyone's personal data will look slightly different.

Companies can track the websites that we visit, the words that we search for when we search online, how we engage with others, so this means maybe who we text, what posts we comment on, and the things that we like online.

Companies can also track what we buy online and what videos we watch.

One way of tracking our data is through something called online, "Cookies." These cookies are files with pieces of data and they help a website to remember your device for next time.

It's because of cookies that we're able to be shown personalised adverts.

Cookies can remember things like your email address and the items you've clicked on, and this results in us being able to see personalised adverts.

Let's do another check for understanding.

Which of these are examples of personal data.

Is it A, location? B, server? Or C, websites we visited? There might be more than one correct answer for this one, so think carefully.

Well done if you said A and C.

Location and the websites that we visited are both examples of personal data.

Well done if you got that right.

You are now gonna put your learning from this learning cycle into practise.

I'd like you to fill in the blanks to show your understanding of data so far.

At the bottom of the screen are lots of different words that have come up in today's lesson.

We've got cookies, online, information, servers, activity, and network.

In the paragraph, there are some missing words.

Can you see if you can fit the right words into the right places in the paragraph? Pause the video, get your worksheet if you're using one, and I look forward to seeing your answers.

Off you go.

Okay, let's have a look and see what I've put and you can see if you've got the same.

You should have written, "The internet is a network connecting online devices around the world.

Data can include personal information, images, and online activity.

Data is stored on lots of different servers and it's specific to who we are.

Companies can track our data by using cookies." Well done if you put the words in the right place.

Okay, we're now going to move on to our second learning cycle.

Why do social media companies want our data? Online data is worth a huge amount of money.

Companies buy online data as they use it to influence their advertising.

Aisha tells this that adverts are important for companies because they increase the amount of money that they make.

By using data to understand more about who we are and our interests, social media companies can choose the relevant adverts of products that we we're more likely to buy.

These are the personalised adverts that we spoke about earlier.

For example, we buy online from an advert, and as a result, both the product company and the social media company earn money.

Social media companies can use our data to show us adverts for the things that might be useful to us.

Jun says that this is a good thing, as it means that we can find out about things that we might like that we otherwise might not have known about if we weren't advertised it.

But Sofia tells us that this does mean that our personal data can be used by others for reasons that we might not always know about.

Okay, let's do another check for understanding.

Which of these is one reason that social media companies use our data? Is it A, to keep our data safe? B, to influence their advertising? Or C, to protect our privacy? What do you think? Pause the video.

Tell the person next to you, tell me or have a think to yourself.

Well done if you said B.

One reason that social media companies use our data is to influence their advertising.

Well done if you got that correct/ I'd like you to have a think about what Jacob says.

Jacob says that social media is free because the companies want us to enjoy using their apps.

What do you think? Do you agree, disagree, or maybe you're somewhere in the middle or you're not sure.

Tell the person next to you, tell me or have a think to yourself.

Okay.

So, Jacob is incorrect.

Social media companies make lots of money by selling our personal information and data.

Well done if you said this or something similar.

Our personal data is used to make guesses about us and these guesses are used to advertise to us.

For example, if we search for clothes online, companies might be able to guess that we also need new shoes, so they might decide to advertise us some new shoes.

If we search online for makeup, companies could also guess that we'd be interested in skincare and hair products.

So once we've searched online for makeup, we might start to see some personalised adverts for skincare and hair products.

Let's do another true or false question.

You're doing a fantastic job so far, so keep it up.

Personal data can be used to influence the adverts that people see.

What do you think? Is this true or false? Pause the video.

Tell the person next to you, tell me or have a think to yourself.

Well done if you said true.

It is true that personal data can be used to influence the adverts that people see.

Let's put your learning from this learning cycle into practise.

I'd like you to complete the table to suggest what data could have been used.

One's already been done for you.

For example, someone has seen an advert that's been targeted to them for walking boots, so we might be able to guess that this person searched online for local walks.

Can you do the same for the other targeted adverts? Have a think about why someone might have gotten these adverts.

Pause the video, get your worksheet if you're using one, and I look forward to seeing what you come up with.

Okay, let's have a look and see what I've put and you can see if you've got something similar.

For this activity, there are quite a few different answers that you could have had, so it's okay if you got something a bit different to me.

So someone might have had a targeted advert for a games console, maybe because they searched for a new game online.

Someone might see an advert for pet toys.

This might be because they searched for pictures of pets online.

And someone might be shown a sketch pad online.

This could be because they searched for drawing videos.

Well done if you've got this or something similar.

We're now going to move onto our final learning cycle.

While done for your hard work so far, keep it up.

How can we control what happens to our data? Social media companies can often do what they like with our data.

For example, they can sell it to either other companies or to advertisers.

Advertisers are people that put up adverts.

They can also analyse your data.

This means to look at it very closely to try and get a better understanding.

They might analyse your data to create a profile about you or to understand how people use their website site.

We do have some control over how our personal information is shared, used, and stored.

For example, we can only accept necessary cookies.

Lots of websites will have a pop-up window when you first go on them.

This popup box will normally ask you to accept all cookies, reject all cookies, or accept necessary cookies.

We can have some control over our personal information by only accepting the necessary cookies.

It's also important to always use strong passwords and keep our accounts private.

So, strong passwords are easy to remember, but difficult for others to guess.

They should be at least eight characters long.

They should be a combination of numbers, letters.

It's also really important to never use the same password more than once.

This helps to keep our accounts safe.

It's also important to think about what apps and websites need to have access to in order for you to use them.

It's important to think about do all apps and websites need access to your location and do they all need access to your photo gallery? We can keep our personal information safe by making sure that we only give certain apps and websites access to our location and photo gallery if it is really necessary.

Let's do another check for understanding.

Which are different ways that we can control what happens with our data? Is it A, restrict access to location and photos? B, allow all cookies from all websites? Or C, use strong passwords? There might be more than one answer to this question, so think carefully.

Well done if you said A and C.

We can control what happens with our data by restricting access to location and photos and using strong passwords.

Well done if you've got this one correct.

It's important that we store our data in secure places.

Secure websites typically have a padlock next to their website address to show you that it stores information safely.

We should use cloud storage where possible as this is usually securely protected.

We should always download apps from secure stores and these are normally pre downloaded onto your device, and it's important to delete apps that you no longer use, and if you have an account online that you don't want anymore, it's important that you ask for it to be deleted.

This helps to make sure that our personal private information stay safe online.

Okay, let's do another check for understanding.

True or false, we cannot control what happens to our data? What do you think? Is this true or false? Pause the video.

Tell the person next to you, tell me or have a think to yourself.

Well done if you said true, but why? We can control our data by only accepting necessary cookies, using strong passwords, restricting access to photos and location, and only downloading apps from secure stores.

Remember, these secure stores are normally already downloaded onto the device.

Now, let's move on to your final practise task.

You've done a fantastic job in this lesson, so keep it up.

I'd like you to these icons to explain how we can control our data.

Pause the video, get your worksheet if you're using one, and I look forward to seeing what you come up with.

Okay, you might have said, "Only accept necessary cookies.

Always use strong passwords and secure websites.

Use cloud storage wherever possible.

Download apps from secure stores like the ones that are already downloaded onto your device, and delete apps that you don't use and accounts that you no longer want." There were lots of different correct answers for this activity, so well done if you got this or something similar.

We're now going to summarise today's key learning.

Today we have learned that online data is worth a lot of money to companies.

We've learned that social media companies use people's data to target them with adverts so that they earn more money.

Our personal data is used to guess things about us, like our interests and what we're more likely to buy.

Social media companies can often do what they like with our personal data, so it's really important we know how to control our information.

We also have some control over how our personal data is shared, used, and stored.

For example, we can reject unnecessary cookies.

We can store information in the cloud, we can have private accounts and we can ensure that our passwords are secure.

If you have any questions or worries about today's lesson, it's really important that you speak to a trusted adult.

There are also some organisations on the screen who are there to help you if you need any support or have any questions.

Well done for your fantastic hard work today.

I'm really proud of you and I hope to see you again soon.
