Lesson video

Hi everyone? My name is Miss Dhillon.

And last lesson, we were exploring the question, where is earth's water? And some of you were really surprised to find out that only 2.

5% of the global water is fresh water.

Incredible.

Now, the question we're going to be exploring, in today's lesson is, what makes up whether? We're going to start by looking at the structure of today's lesson.

We're going to start with the star words then we're going to look at the components of weather, there are six in today's lesson.

Then we're going to look at the difference between weather and climate.

And finally, we're going to consider, how does the weather affect us? For this lesson you will need an exercise book or paper, pen or pencil, and definitely your brains.

On the screen you can see the key words or the star words for today's lesson.

I'm going to be explaining the star words in more detail throughout the lesson.

But for now, let's use my turn-your turn, to say these key words.

Are you ready? Weather, climate, temperature, humidity, atmospheric pressure, precipitation, troposphere, thermometer and meteorologist.

Good job.

So you can see that some of those star words look a little bit tricky, but I will be explaining them in more depth, in today's lesson.

So let's start off by thinking about the question, what is weather? We talk about it a lot but what does it actually mean? The term weather refers to the temporary, which means not permanent, it's not all the time it's just for the now, is temporary conditions of the atmosphere.

Because they're temporary because they can change from hour to hour or from day to day.

So the weather in one moment, it can be really nice on the outside, like it is right now, and then all of a sudden, in 15 minutes time, it can start raining.

So that's why weather is temporary.

Can you say that word after me? My turn-your turn, temporary.

Good job.

Now, with the weather, there are six main components or parts.

One of these is temperature, atmospheric pressure, wind, humidity.

Now humidity is how much moisture that is in the air.

So when you go to a really hot tropical country it has quite high humidity.

Which means there's a lot of moisture in the air, you can usually feel it on your skin as well.

Precipitation.

Do you remember what is precipitation? Remember, it's not just rain.

Good, it could be rain, snow, sleet or hail.

And finally, the last component of weather is cloudiness.

So, there are six components that make up weather.

Can you say all six for me, starting from the top? Good job.

Okay.

So, now we know, that the weather is made up of six components.

I would now like to think about most of the weather, where does it actually occur? So most of the weather actually occurs in the troposphere.

My turn-your turn, troposphere.

Good job.

Now the proper troposphere is from the earth surface, so from the ground, to a height of about six to 10 kilometres.

And this is the height where you usually see aeroplanes flying.

Do you know how we measure temperature? Some of you might have already know the answer and if you do well done.

We use a thermometer to measure how hot or cold it is.

My turn-your turn, thermometer.

Good job.

And thermometer it usually measures temperature in either degree celsius or in fahrenheit, depending on where you are and which one you prefer to use.

We are now going to play a little memory game and I know how much you love to play these games with me.

So, I wonder if you can remember, all six components of the weather.

Now you can pause the video before we start the game, just if you need a little bit longer to learn all six on the screen.

So you do pause it before we start the game.

Okay, so hopefully you've gone through all six, and now we will start a memory game.

So which of the six main components of weather is missing? Say out loud.

Did you say wind? Good job.

Okay, on that one wind is missing.

So now you know how the memory game works.

Are you ready for the next one? What's missing this time? Say out loud.

Good, you should've said cloudiness is missing.

Next round.

Good, so you remember the pink boxes missing and it is? Temperature, good job.

Next one.

Say out loud.

Good, is humidity.

Well done and keep going.

Are you ready for the next one? I know it's getting a little bit harder, but keep trying, 'cause you're doing a really good job.

Did you say precipitation? If so, well done.

That is the correct answer.

Final one.

Can you remember the last component? Out loud? Good.

Atmospheric pressure.

This is how much pressure there is in the atmosphere.

Wow, all's on recall.

I hope you had lots of fun playing that memory game because I definitely really enjoyed it too.

It really helps you revise and make sure that you can remember all the key information.

So you can play that yourself if really enjoyed that game.

Now that we have discussed what weather is, which is temporary conditions in the atmosphere which change day to day and hour to hour, now I would like you to brainstorm and write down all the types of weather that you can think of.

For example, I know that one type of weather is cold.

We can feel cold because it can be cold outside.

So, writing a bullet point list, can you continue brainstorming all the types of weather? The first one has been done for you.

Pause the video now, to complete the task.

Okay, there's lots of answers here.

So on the screen, you can see some of the types of weather that I could think of and you might have mentioned.

Have a look at the list and see, which ones did you not think of? We have now discussed what weather is, so let's just recap before we move on.

Weather is temporary.

Which means it change from hour to hour and day to day.

Now let's look at what climate is, because climate is slightly different.

And sometimes people confuse the two.

Climate is the average weather conditions of a location, over a period of time.

So for example, we can say that in England, on average, we have quite warm summers, so it gets really quite warm in June, July and in August, and we have mild winters, which means our winters are not too cold.

Not as cold as for example, Russia or Serbia, for example.

And we do have rainfall all year round.

So that is the average conditions in England.

So it's different from weather because weather changes day to day or hour to hour.

Climate is an average.

Finally, a meteorologist.

Now, a meteorologist is someone who studies the weather.

Who is a meteorologist? Good, someone who studies the weather.

Can you say after me, meteorologist.

Good job.

So, a lot of new information.

The key thing to remember is climate is an average, weather is temporary and changes from hour to hour and day to day.

Good job too.

So now I'd like you to pause the video and have a go at the task on the screen.

Did you remember that correctly? Well done.

Let's have a go at practising saying it one more time.

Meteorologist.

Good job.

A meteorologist is someone who studies the weather.

Now that I have explained the differences between the weather and the climate, I would now like you to read each statement that is on the screen and say whether it is climate or whether it is weather.

Let's have a go at the first one together.

Let's read it.

The Sahara desert is hot and dry all year round.

Now, I can see that, the statement is describing the average weather conditions in the Sahara desert all year round.

Therefore I think that it's describing the climate not the weather.

Let's double check if I'm correct.

Awesome, so I am correct.

Okay so, it's saying, the average conditions is really hot and dry all year round, so that is climate.

So now you want to stand the task let's have a look at the next one.

Today has been really hot and sunny.

Is that describing the climate or the weather? Say out loud if you having it already.

So you should have said that is describing the weather because it's describing the conditions on a particular day.

Last Wednesday was really windy.

Is this just describing the climate or the weather? You should have said weather.

And this is because it's describing what it's like on one particular day even if it is just last Wednesday.

Greece is always hot in the summer.

Is that describing the weather or the climate? For this one, you should have said climate because it's describing the average weather in Greece, which is hot all summer.

Let's have a look at the next one.

England has cold and wet winters.

Is that describing the weather or the climate? You should have said it's describing the climates because it is describing a long period of time, the whole of winter, and it's saying on average, it is cold and it is wet, in England.

There was a huge thunderstorm last night.

Is that describing the weather or the climate? For this one, you should have said that it's describing the weather because it's happening on a particular day, in this case, last night.

The average temperature in Sydney, Australia, is 23 degrees.

As a challenge an you pick the word that gives this away? Okay, so hopefully, you notice the word average and straight away you said that this is describing the climate.

This morning we didn't have to go to school because it snowed.

Is this describing the weather or the climate? So this is describing the weather.

And the reason this is, is because it's happening this morning, so it's on a particular day, and as a result of it you can't go to school.

So hopefully, you now are better understanding the difference between climate, which is an average, and a weather, which changes by an hour or by day to day, so therefore it's temporary.

Now it's time for you to have go at a task.

What I would like you to do is much of the key words with the correct definition.

Pause the video now to complete this task.

On the screen, you can now see the correct answers.

Take a moment to check your answers.

Did you remember all three correctly? Well done if you did.

I know you're trying really hard to remember all the new information.

So really well done and good efforts so far.

We are now going to learn about how the weather affects us, you and I.

One of the things you probably do every morning is get up and look outside the window to see what the weather is like.

Look outside the window now.

What is the weather like today? Looking outside and listening to the day's forecast helps you decide what clothes to wear.

For example, if it is nice and sunny outside, you might want to wear shorts or a dress.

But if it is really cold and windy outside, you would want to wear a jacket.

So the weather affects our decisions about what we would like to wear that day.

The weather also affects what activities we want to do in the day.

If you don't have school and the weather is looking really sunny outside, you might want to go on a picnic or play some sport at the park.

A rainy day, however, might mean you think about visiting a museum or staying in doors where you're nice and dry and you can read a book instead.

Or weather can also affect us by making us change our plans.

For example, if I had a football match in the afternoon, but in the morning it was raining, it might mean that the football pitch is flooded.

And therefore my plans to play football have to be cancelled because the weather doesn't allow us to play.

That is an example of how you might change your plans as a result of the weather.

The weather can also have a big impact on travel.

For example, trains can be delayed during extreme weather.

For example, if it's really, really hot.

And this is because metal expands when it is exposed to heat.

As a result is not safe to travel on trains and therefore that's why they might be delayed or completely cancelled as a result of severe weather.

Another example, is flights being delayed, or being cancelled due to weather.

Sometimes the weather outside looks fine but the flight is still delayed because the airline wants to make sure that, that on the whole journey, everything is fine.

And that there's nothing that might put the crew, the plane or the passengers in danger.

Now we're going to think about another way that weather can affect us.

A very recent example of how weather can affect people, is in India.

Heavy rainfall has caused crop damage in six states in India.

Heavy rainfall can affect the quality of the crop.

For example, wheat.

And now this makes it really hard for farmers to sell their crops.

This then puts them in a lot of pressure too.

Because they rely on selling their crops in order to make money to feed themselves and their families.

It also means that if their crops are damaged, all the hard work they put into growing this crop, goes to waste.

Severe weather, such as floods, which you can see on the left hand side and tornadoes or hurricanes and blitzes, they can destruct people's life because of the destruction that they cause.

People might lose their homes or loved ones, like family or friends, and this can have a huge impact on someone's life.

Have a look at the pictures on the screen.

On the left, you can see damage caused in Orlando, USA, due to a tornado.

On the right hand side, you can see a town that has been flooded.

What damage can you see or think has been caused due to extreme weather? You will use the pictures to help you but you might also have other ideas of how it might have affected the people involved.

Pause the video now, to come up with all your ideas about how the weather has affected the people that live in these towns.

So on the left, you can see that the car has been damaged by a tree.

You might have said that this would affect someone because they might rely on their car to get to work or take people to school.

Therefore it's made these daily tasks much, much trickier because they haven't got a car anymore.

That works.

On the right hand side, you might've said, because the street is full of water it might have got into people's homes and therefore ruins their furniture, their carpets, electronics, et cetera.

You might've also thought how are people going to leave their houses to go to the shops, for example, if there is a lot of water on the streets? Well done, if you said some of these things.

You are really thinking about the impact of the weather on other people's lives.

Now I would like you to think about the effect of weather on you.

Pause the video to have a go at the task on the screen.

In the past, how has the weather affected you? There is no right or wrong answer because this is about your own experience.

Pause the video now to complete the task.

Can you read your answer out loud to me? Good job.

So on the screen, you can see some examples of what you might have said.

Remember, there is no right or wrong answer.

This was just about your own personal experience so that you realise that weather affects us all.

Is now time for you to complete your end of lesson quiz.

Thank you so much for your efforts today and I can't wait to see you again in lesson three, where we will be exploring the question; why does it rain? What an interesting question to ask.

Bye everyone.
