It’s part of the reason we look so feverishly for water on other planets across the universe, and consume it consistently every day here on Earth. The initial signs of dehydration are the obvious dry mouth, following which, your urine becomes darker with a stronger odor, as your body attempts to conserve more fluids.
In studies observing hydrated vs dehydrated participants, the same task required more brain power and oxygen in dehydrated individuals compared to those fully hydrated. Beyond 3-5 days without water, and your body will begin to shut down its organs, and eventually the brain. And as our personal drinking sources become increasingly contaminated, over 783 million people on earth are unable to access clean water. Scientists around the world are trying to find solutions to this problem – from attempts to remove salt from ocean water, tap into underground aquifers and creating innovative water filtration systems. If we look to space, NASA has developed technology for astronauts to turn their urine into water more pure than what we drink on earth. If you want to help in the mission to end global thirst, join in World Water Day on March 22nd. NutrientsA nutrient is a substance that provides nourishment essential for the maintenance of life and for growth. LubricatesWhen a substance is applied so as to minimize friction and allow smooth movement. UrineA watery, typically yellowish fluid stored in the bladder and discharged through the urethra. SweatingMoisture exuded through the pores of the skin typically in profuse quantities as a reaction to heat, physical exertion, fever or fear. PoopingAn informal term used for excreting, when one goes to the toilet to relieve their bowels and discharge faeces from the body.


Have trouble swallowingThis phrase means that it would be difficult for something (especially food or drink) to pass down the throat.
DeliriousIn an acutely disturbed state of mind characterized by restlessness, illusions, and incoherence; affected by delirium. ContaminatedWhen something has been made impure by exposure to or addition of a poisonous, polluting or harmful substance. Water charitiesA charity is an organisation set up to provide help and raise money for those in need. Ana is a fan of giving away free and useful materials both for English learners and teachers. H20 is the most abundant molecule in the human body making up, on average, 65% of an adult. The lack of H20 then begins to affect your brain – you may feel light-headed, have a slower response time and decreased ability to feel pain. Interestingly, studies looking at elderly patients who suffer from delirium, found that many are simply suffering from chronic dehydration in the first place.
And most of this water is actually used to grow crops, approximately 500 billion litres of fresh water is used daily for agriculture in the USA alone, with another 500 billion litres to cool electrical power plants.
There are a lot of really amazing projects out there, like Water.org or even the awesome UNICEF app which donates 1 day of clean water to a child in need, for every 10 minutes you put your phone down. When you work through the night, moving quickly to try to get a job done, this is an example of working feverishly. It is one of the body’s chief means of eliminating excess water and salt, and also contains nitrogen compounds such as urea and other waste substances removed from the blood by the kidney.
Many charities are specific to certain people or areas of need, in this case supporting people or communities with problems such as water shortages or lack of clean drinking water.

As a universal solvent, it carries nutrients and hormones through the body, regulates body temperature, cushions our joints and even lubricates our eyes. After even more time without water, the blood stops flowing to your skin, reducing heat loss but increasing your core body temperature.
So, in other words, this phrase means that the human brain actually shrinks when one’s body is dehydrated.
Assign each group a mascot (teams can be given mascot signs made from the food cutouts from the previous simulation): Turtles, Fish, Deer, and Raccoons. Have the Turtles go to center A, Fish go to Center B (centers A and B are the same), Deer go to Center C, and Raccoons go to Center D (centers C and D are the same).
The students analyze the text from the instructions and try to make sense of it, having group discussions, and then decide if the settlers followed the directions. The video summarizes why the settlers chose Jamestown (ships could moor closer to shore, offered protection from enemies ships as the channels were too narrow to escape easily once being fired upon) but also discusses some of the issues that arose from the location (poor water quality caused many diseases and death, water was not good for growing crops). If the students do not finish their work for a particular center, work should be taken home for homework or done during free time.
