Hello, my name is Ms. Juret Jan, I'm so excited to be learning with you today.
I will be guiding you through every step of our geography lesson today.
We are going to have a great time learning together.
Let's start our learning journey.
Welcome to today's lesson from our unit called The Water Cycle, why is it important? This lesson is called Water Supply and Demand in the UK.
Your learning outcome will be to explain why there is a need to move water from place to place in the UK to meet demand and how this is done.
Some of this learning is brand new, but I'm here to help you.
This links back to previous learning you might have done about the water cycle and the processes in the water cycle, and also thinking about how buildings collect rain water and how water enters and leaves buildings.
You might have also done some thinking around why water is so essential for human life and identified some of the causes and consequences of people not having access to safe, clean water.
Here are the key words that we will be using together in today's lesson.
Let's practise saying them by doing my turn, your turn.
Reservoir.
Reservoir.
Aquifers.
Aquifers.
Pipeline.
Pipeline.
Consumption.
Consumption.
Good job everyone.
Let's find out what these key keywords mean.
Reservoir, a reservoir is a lake built behind a dam to store water.
Aquifers, aquifers are porous rocks that can store and filter water.
Pipeline, pipelines transfer something from one place to another, usually a liquid or a gas.
Consumption, consumption is the process of using up resources.
I want you to be using these keywords throughout our lesson.
Here are the learning cycles that we will be working through together in today's lesson.
First, we're going to be thinking about where water comes from in the UK and then we'll be thinking about if all parts of the UK have enough water.
I'm really excited to get started.
I hope you are too.
Let's start our lesson.
Fresh water is water that is not salty.
Salty water is mainly found in oceans and seas.
We can't drink salt water, so all the water that we use for drinking and washing is fresh water.
Fresh water is water that's usually found in lakes and rivers and are also some ways to collect it and store it, which we'll be learning about later.
In the UK there are fresh water sources above and below ground.
So we're going to take a look at the fresh water sources above ground, and then we're going to look at the fresh water sources that are underground.
In the UK there are many surface water sources.
Rivers and lakes are natural surface water sources that provide us with a supply of fresh water.
Surface water means water that's not underground.
Part of north west England has many large lakes.
It's called the Lake District, and you can see that the Lake District is represented in that map on this slide.
Reservoirs are surface water sources that have been specially constructed to collect and store huge amounts of water.
Reservoirs are often built in places where there is a lot of rainfall, and that way those reservoirs can collect and store water that falls to the ground through precipitation.
Rutland Water, shown here, is one of the biggest reservoirs in the UK.
So there you can see a picture of Rutland Water, one of the biggest reservoirs in the UK.
And remember we said a reservoir is somewhere that collects and stores water.
It is time for a quick check here.
What is the main reason why reservoirs are built? A, to collect water in places where it rains a lot.
B, to give fish a place to live, or C, to use them for sports like sailing.
Pause the video now and complete this check.
How did you get on? Did you say A, the main purpose why reservoirs are built are to collect water in places where it rains a lot.
That's correct, well done.
You can give yourselves a big thumbs up.
In the UK there are also underground water sources in some places.
So we've already talked about where surface water is collected and now we're moving on to where underground water sources are.
Underground water sources are called aquifers.
The biggest aquifers in the UK are located in the south east of England, and you can see it located there in those blue areas on the map.
An aquifer is a large area where the rock beneath our feet is porous.
A porous rock lets water flow through it and be stored in it.
So it means it's got lots of little holes or cavities or spaces where water can go inside and be collected and stored.
Chalk is a porous rock.
The famous chalk cliffs at Dover in the south east of England are parts of an aquifer.
It's now time for a true or false check.
That means you've got to think really carefully about whether or not this statement is true.
In the UK there are surface water sources and underground water sources.
Is that true or false? Pause the video and answer that question.
How did you get on? Did you say true? That's correct.
In the UK there are surface water sources and underground sources, and we've looked at examples of both.
It's now time to justify your answer and think about why it's true.
A, reservoirs are on the surface and aquifers are underground, or B, Dover's chalk cliffs are part of a big aquifer.
Pause the video now and justify your answer.
How did you get on? Did you say A? That's correct.
In the UK there are surface water sources and underground water sources.
Reservoirs are on the surface and aquifers are underground.
Well done if you were able to answer that check correctly, you can give yourself another big thumbs up.
It's now time for task A.
What I would like you to do is to solve the clues to complete the puzzle.
You've got to look at where all those little boxes are and fill those boxes with letters.
Each of those boxes form to make separate words.
And where you see the numbers inside the boxes, that links to one of these statements or questions.
So if you solve the puzzle and answer those questions, you'll be able to write the answers into the grids and complete the puzzle.
The clues that you have are number two, a natural surface water source that holds a lot of water.
Number three, a surface water source that flows towards the sea.
Number four, a large underground water source.
And then looking at clue number one, which goes down, a lake built to contain rainwater.
Pause the video now and complete task A.
How did you get on? Were you able to solve all of those clues to complete the puzzle? The answer to clue number two was a lake.
A lake is a natural surface water source that holds a lot of water.
The answer to number three was a river.
A surface water source that flows towards the sea is a river.
Number four was aquifer, a large underground water source.
And finally, number one, which went down, a lake built to contain rain water is called a reservoir.
Well done if you were able to solve all of those clues to complete the puzzle.
You can give yourselves a big thumbs up.
It's now time to move on with our learning.
We are going to be thinking about if all parts of the UK have enough water.
Water consumption is the greatest in places where lots of people live.
So the places that have the most people use the most amount of water.
They consume more water than places that have less people living there.
The demand for water is greatest in towns and cities across the UK, especially in large cities like London and in areas with high population such as the south east of England.
So these areas have got great numbers of people living there, and so the water consumption in these places is the greatest.
The greatest demand for water in the UK is also found where the supply of water is the lowest.
We've got two graphs here, one that shows rainfall and the other one that shows temperature.
I wonder if you can look at these two graphs and think about interpreting what they show us.
Pause the video and explore these two graphs.
Let's look at these two graphs together.
So the one shows the one on the left shows rainfall and the one on the right shows temperature.
Supply is lower in the south and east of England where it is warmer and there is less rain.
So if you can see the rainfall in those areas is less than the rest of the UK and the temperatures are also hotter because those areas are further south.
And remember we talked about areas where there's more population, and again, we talked about the south and the east of England being areas where there are more population.
So those areas need a lot more water, but there's naturally less water there.
It's time to have a quick check.
Why is demand for water greatest in towns and cities? Talk to a learning partner and explain your thinking.
Pause the video now and answer this question.
How did you get on? Did you say things like people use lot of water every day for things like washing and drinking? Yes, and there are lots of people living in towns and cities, so they need lots of water.
Remember, we've talked about towns and cities having a greater population than areas of villages and smaller communities, and so those areas consume a lot more water.
When there's not enough water in an area to meet demand, we have to find another way to provide people with water.
This is when reservoirs are most useful.
Remember that reservoirs collect rainfall in areas where there is a greater amount of rain that falls.
Reservoirs store huge amounts of water in places that have more water than they need.
Large pipelines are constructed from reservoirs to supply water to areas that need water.
Pipelines transfer water so that areas without enough can meet demand.
So these pipelines in the picture shown here are taking water from areas where there's a lot of water, areas that might have reservoirs to areas that have less rainfall and areas that don't have enough water.
The map shows some examples of water transfer in England and Wales.
You can see that different towns and cities are represented there in blue, and there's arrows that show the transfer of water.
For example, water is transferred from the Lake District where there is lots of water to the big city of Manchester that has a great demand for water.
Can you see any other transfers near your home? Pause the video now and explore this map.
Think about where water is transported from.
An area that has a high amount of water, but less demand for it to an area that has less water and a greater demand.
How did you get on exploring this map? Did you see any transfers near your home? Did you have a look at all of the blue water sources that are located on this map and then follow the areas to see where that water is transferred? Let's have a closer look at this example of the Lake District.
There you can see the Lake District located on the map.
Water collected in the Lake District is transferred to the large city of Manchester, and you can see that through the direction of the arrows going down.
You can see transfers to big cities like Birmingham, London, Derby, Liverpool, and Manchester.
So remember that we can transfer water that's collected in areas that have a high amount of rainwater, such as the Lake District and transfer it to areas that have less rainwater in the south east of the UK, and that's how we can meet the growing demand for water in different parts of the UK.
All of that water is transferred through pipelines.
Well done everyone.
That's great learning for today.
It's now time to have a quick check here.
Which of these is a solution for meeting demand for water? A, selling more water in bottles in the shop.
B, closing swimming pools to save water.
C, transferring water by pipelines from reservoirs.
Pause the video now and complete this check.
How did you get on? Did you say C, transferring water by pipelines from reservoirs? That's correct.
That is a solution for meeting the demand for water.
Good job, everyone.
You can give yourselves a big thumbs up.
It's now time for task B.
What I would like you to do is to talk to your learning partner about how water is supplied to areas that do not have enough.
Explain your thinking.
Try to use the map to give some examples and include keywords such as consumption, reservoir, transfer, and pipeline in your answer.
Pause the video now and complete task B.
How did you get on with task B geographers? How is water supplied to areas that do not get enough? I asked you to answer that question and to explain your thinking.
You could have said in places where it rains a lot, we build reservoirs to hold all the extra water.
There is more than enough water in places like the Lake District.
Then we build pipelines to transfer the water from the reservoir to places with more demand like Manchester.
So we are talking about collecting water in areas where there's a high amount of rainfall and collecting them in places called reservoirs and then using pipelines to transport them to other areas where the demand for water is high, but the rainfall is low, so it can't meet demand in that area.
Well done if you are able to explain your thinking and explain how water is supplied to areas that don't have enough.
Well done everyone you've thought really hard about why there is a need to move water from place to place in the UK to meet the demand.
Remember, we've talked about the demand being in areas where there's a greater amount of consumption like towns and cities and moving water from areas where there is a high amount of rainfall and all of that water can be collected in the reservoirs.
Good job, everyone.
We've now come to the end of our lesson.
It's time to go through a quick summary of all the learning that we've completed together today.
The UK has surface water sources and underground water sources.
Reservoirs, rivers, and lakes are surface water sources.
Aquifers are underground water sources.
Remember, an example of an aquifer are the chalk cliffs at Dover and they're porous, which means that they can store and collect water underground.
In the UK, the demand for water is highest where the supply of water is lowest.
So the demand is highest in areas that are built up like towns and cities, for example, Manchester and London.
Areas that have a high amount of water include the Lake District.
Pipelines transfer water from reservoirs to meet demand in areas that need water.
Well done everyone.
You've been fantastic today and the learning that we've completed together was really tricky.
Well done for joining me and for sharing your learning with me.
I'll see you soon for more geography lessons.
Goodbye.
