8U's Water in the World Questions by https://padlet.com/missbrady21/6zej4n324wajd84v These are the questions and answers to the classes KWL 'want' questions, and common questions I am getting asked in class. en-us 2021-08-30 11:53:47 UTC 2025-10-29 14:34:34 UTC hello@padlet.com How can water damage the world? missbrady21 https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704331576 A lack of water can damage the world in many ways:
- It can leave people without drinking water. We need water to survive. If we have no water, all of us will die.
- It can leave communities into 'water wars', as groups or countries fight to have a stable water supply in the country. This usually means water having a high price - leaving those who are poor, no water availability. 
- The increase of global warming is melting the ice caps in the Antarctica, and this can lead to rising sea levels. This means small island countries or people who live near the coast will experience major flooding and destruction. ]]> 2021-08-30 11:56:23 UTC https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704331576 What trouble can water do? missbrady21 https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704331831 Water can do more trouble then you think. If we don't have water we can't:
- Use water for drinking. We need water to survive. 
- Use water for food. We would not be able to water crops, and feed animals 
- Use water for clothing. We would not be able to make any clothes - no cotton for your t-shirts.

If climate change, global warming, water wars, drought, and the over-use of water keep happening, it very well may happen sooner then you think.
I do hope you don't see day zero, but just like our rural communities in Australia that day came in 2018-2019 before we got heavy rainfall. We should be doing our part, even now, while we have a good amount of water in our dams and rivers to ensure we are saving water, because one day we may just run out.

What do you think? ]]> 2021-08-30 11:56:50 UTC https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704332139 How much rain a year do we need to have a steady supply of water? missbrady21 https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704332428 We need a nice consistent amount of rain across the country to ensure that our dams are full enough for our cities and towns to use, and to keep our rivers and lakes flowing. There is not a magic number. However, with the increase of global warming and climate change happening in Australia we are seeing warmer days for longer each year - this means less rainfall, and that means less water in our dams, rivers and lakes. If we don't look after water now, and store it so we can use it when we are in need - we will run out of water if climate change and global warming keep happening at the same rate currently.]]> 2021-08-30 11:57:05 UTC https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704332428 How much will it cost to desalinate enough water to have a steady resource? missbrady21 https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704333209 Desalination is an expensive process. It may give a steady resource, particularly when a place is in drought.  But many places, including Australia only use desalinated water when in severe drought, due to the expensive cost. 

For about 3000 litres of salt water, the process of desalination costs $3-4, depending on electricity costs where the desalination is. 
This price does not include the set up of station (a medium station costs about $80 million to set up, a large station up to $250 million), station maintenance cost, and operating costs (eg employment of workers)]]> 2021-08-30 11:57:28 UTC https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704333209 How much is desalination? missbrady21 https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704333417 For about 3000 litres of salt water, the process of desalination costs $3-4, depending on electricity costs where the desalination is.

All the water we have on Earth is the water we have. Water moves through the water cycle. You will often hear of 'desalinating' water - meaning using ocean water, and removing the salt from it so we can use it for drinking/cooking purposes. Or 'drilling' for water from our Earth's underground water source. However, all these types of water are already on our Earth.]]> 2021-08-30 11:57:52 UTC https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704333646 Does the water go in a circle? Does that mean all the water on this Earth has been here since Dinosaur times? missbrady21 https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704334265 Yes the water goes in the circle around the globe - it's called the water cycle. Yes that means the water you may see today could of been here since Dinosaur times. Watch the video to remember how the water cycle works. ]]> 2021-08-30 11:58:21 UTC https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704334265 What will happen if we keep running out of water? missbrady21 https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704334548 Our planet as a whole may never run out of water, it's important to remember that clean freshwater is not always available where and when humans need it. We have all the water we need to survive, but it is not always available when we need it.
More than a billion people live without enough safe, clean water. Also, every drop of water that we use continues through the water cycle.

What was happening then? missbrady21 https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704334752 In 2019 the dams in Australia were the emptiest with some sitting at 7% capacity.

Reducing global warming and climate change will help stabilise the climate, and allow for rainfall to fall where it needs to be - this will make for a stable water supply into our dams, and rivers. To stop or reduce global warming and climate change, everyone needs to work together across global and local scales. The united nations, governments, communities, non-government organisations and individuals need to work together to do their part. Check out the video, in how you can save water!

You couldn't wash your car, or water your garden at certain times in the day. 
Rural Australia seems to experience water stress a bit more than our coastal communities, due to their geographical location (less rainfall), and because it's harder to get water supplies to them - a lot of piping networks under the ground (water instructure). 
So no, rural communities are not the only ones that experience water stress. They are more likely to experience it first.]]> 2021-08-30 12:00:02 UTC https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704336127 Do only the hotter states of Australian experience water stress? missbrady21 https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704336396 The answer to this question is no. The 'hotter' states of Australia are more likely to experience water stress FIRST and MORE OFTEN but other states, particularly with global warming and climate change are also experiencing times of water stress.]]> 2021-08-30 12:00:16 UTC https://padlet.com/missbrady21/6zej4n324wajd84v/wish/1704336396
