  • Feel free to print the slide for each team. Make them submit it back with the answers on the back perhaps so the questions aren’t floating round if you have other classes doing this activity. After they submit the answer, document their points on the page for their records and back up for you. They should keep this in a team notebook.
  • More water facts that can be added to the slide show and tests if desired. (Source: http://www.epa.gov/reg5rcra/wptdiv/p2pages/water.pdf) EARTH’S TOTAL WATER SUPPLY Oceans (saltwater) = 97.2% Fresh water = 2.8% EARTH’S FRESH WATER SUPPLY Ice caps and glaciers = 82.1% Groundwater (aquifers*) = 14.3% Surface water (lakes, rivers, and streams) = 2.4% Air and soil = 1.2%
  • (plasma being the main medium for excretory product transportation), and blood cells themselves. Blood Is made of white cells, red cells, platelets, and plasma. The plasma is the part that has water. Plasma is 55% of the blood. 90% of plasma is water. So….90% of 55% which is 49.5%. What percentage of blood is water? 90% of 55% which is 49.5% When spun in a centrifuge, the cells and cell fragments of blood are separated from the liquid intercellular matrix. Because the formed elements are heavier than the liquid matrix, they are packed in the bottom of the tube by the centrifugal force. The light yellow colored liquid on the top is the plasma, which accounts for about 55 percent of the blood volume and red blood cells is called the hematocrit,or packed cell volume (PCV). The white blood cells and platelets form a thin white layer, called the "buffy coat," between plasma and red blood cells. Plasma is the watery fluid portion of blood (90 percent water) in which the corpuscular elements are suspended. It transports nutrients as well as wastes throughout the body. Various compounds, including proteins, electrolytes, carbohydrates, minerals, and fats, are dissolved in it.

  • http://nutrition.about.com/library/blwatercalculator.htm When one team reaches the bonus question, stop the class and give everyone the bonus question at the same time. Teams can work on this one as well as their current question. Have project manager provide the answer, listing each member and individual water intake, team tally. I had them print page 1 of 2 and write their names on it. Teams were using multiple computers to get the job done. They could copy and past the information into a word doc and label each member, but they would all have to use the same computer or send the information to one person.
  • Students would need nine sources here perhaps to gain full credit. I was not able to find one source that had all the information. The last question can be calculated by using the water lost in a day times the number of days you can survive without water.
  • Students could present this with a bar graph of body outlines with the water levels shaded in. Students could list the actions and the amount of water. Attach page of math calculations!

  • Most people have never thought about the above because they have NEVER been personally confronted with an extended shortage of fresh safe drinking water at any time in their lives. In many other countries, they think about this every day. A shortage of fresh safe drinking water is a daily problem Keep in mind that these numbers only represent what the human body needs on the inside. We haven’t even thought about washing your hands, brushing your teeth or bathing.

    5. 5. Making earth little softerEarth as water planet• Earth is often referred to as `the water planet.• Earth is unique amongst planets of our solarsystem because of its abundant water - inoceans, atmosphere, glaciers and as freshwater on land.• Without water, life could not exist• Ocean Water: The vast majority of water on theplanet is the salt water in the oceans and seas.• Groundwater: Freshwater is stored inunderground aquifers. Water that enters anaquifer remains for an average of 1,400 years!
    6. 6. Making earth little softerWater on the earth• Water is the main constituent of ecosystem & isthe basis of known life forms, including humans• It was the basis of the origin of life on our planet• It is essential to civil, agricultural & industrial use• Men recognized since ancient times itsimportance, and identified as one of the mainconstituents of the universe, giving it a deepsymbolic value, found in major religions.
    7. 7. Making earth little softerSignificance of water• Water is an integral part of life on this planet.• It is an odorless, tasteless, substance thatcovers more than three-fourths of the Earthssurface.• Most of the water on Earth, 97% to be exact, issalt water found in the oceans.• We can not drink salt water or use it for cropsbecause of the salt content & is heavy• We can remove salt from ocean water, but theprocess is very expensive.
    8. 8. Making earth little softerThree forms of Water• Solids: When water becomes very cold andfreezes it changes from a liquid to a solid state.It has a definite form and shape.• Liquids: When water takes the shape of itscontainer it is in a liquid form.• Gases: When water is seen in a vapor form andhas no definite size or shape it is in a gas form.

    57. 57. Making earth little softerFunction of Water in body• Identify main functions of water in the body’smetabolic process.• It delivers oxygen and nutrients to different parts• It removes toxins and waste from the body• Water also has other functions:• Regulates body temperature throughperspiration• Reduces friction between joints and facilitatesmovement• Acts as a cushion between organs to protect• Facilitates normal functions of body processes.
    58. 58. Making earth little softerWater & Body• In what way the body lose water & How much?• A person can live without food for several weeksbut life cannot last more than few days withoutwater . Human body is 60-70 % water. We takewater with food and drink, and lose it in urine, insweat, and in our breath (as water vapor)• A person loses 1.89-2.83 lit of water every dayas a result of their normal body functions• This much loss means if a person doesnt getany fluids for about three days, they will die.• 6-9 quarts (5.678-8.517 l) of water loss wouldcause death.
    59. 59. Making earth little softerWater & Body• Recall how much water the average personloses in one day through their urine, sweat, andnormal breathing.• Percentage of overall water loss occurs when:• Thirst is perceived.• Strength and endurance decrease.• Delirium and blurred vision become a problemand you can not move.• A person dies.• Calculate the amount of water loss for eachbased on the amount of water lost per day.
    60. 60. Making earth little softerWater & Body• In one day the person loses between 2 to 3quarts of water through their urine, sweat, andnormal breathing. If a person doesnt replacethat lost water, then dehydration begins tooccur.• At 1-2% dehydration, thirst is perceived. (.6-.9quarts)• At 5% dehydration, a person becomes hot andtired, and strength and endurance decrease.(1.5-2.25 quarts)• At 10% dehydration, delirium & blurred visionbecome a problem, can not move.

    64. 64. Making earth little softerOther Water Facts• 1.2 billion people lack access to safe water,• ~one-sixth of the worlds population lack accessto adequate sanitation services.• 6,000 die every day from diseases associatedwith unsafe water, poor sanitation & hygiene.• Unsafe water & sanitation cause an estimated80 % of all diseases in the developing world.• Women and girls tend to suffer the most as aresult of the lack of sanitation facilities.• One flush of a Western toilet uses as muchwater as the person in the developing worlduses for washing, drinking, cleaning & cooking.
    65. 65. Making earth little softerWater facts..Continued• Water use has grown at twice the rate ofpopulation during the past century. The MiddleEast, North Africa and South Asia arechronically short of water.• In developing countries, as much as 90 percentof waste water is discharged without treatment.• Over pumping groundwater for drinking waterand irrigation has caused water levels to declineby tens of meters in many regions, forcingpeople to use low-quality water for drinking.
    66. 66. Making earth little softerWater facts..Continued• Losses of water through leakage, illegal hook-ups and waste amount to about 50 percent ofwater for drinking and 60 percent of water forirrigation in developing countries.• Floods affected more than 75 percent of allpeople impacted by natural disasters during the1990s and caused over 33 percent of the totalestimated costs of natural disasters.

    70. 70. Making earth little softerLearning Objectives• To understand that water is a global issue andnot just within certain countries• That lack of water is not the only issue in waterinsecurity and stress• Access to sanitation is linked to poverty• Development can hinder water quality, accessand supply
    71. 71. Making earth little softerHuman water needs• In the US usage in gallons/person/day• A person needs about 1 gallon water/day forhydration• Personal use - 188• Additional 657 used for irrigation, industrial use• Total per capita use is about 2000gal/person/day• If world’s water supply were 100 liters, theusable supply would be about 0.5 tsp(teaspoon)• US has highest per capita water withdrawal,followed by Canada, Australia, Russia, Japan

    94. 94. Making earth little softerWater Security Crisis• 2nd world water forum in 2000 deemed water akey issue• Health, welfare and livelihoods depend onsecure supplies• Demand and misuse are high• World water forum
    95. 95. Making earth little softerAsia and Pacific• 1/3 of pop’n lacks access to clean drinkingwater• 500,000 infant related deaths through diarrhoea• Levels of bacteria from human sources is 10xhigher than recommended levels• Agriculture accounts for 90% of freshwaterwithdrawals in S. Asia• Aquifer depletion in Asia has reduced wateravailability per capita by over half• Withdrawals in W. Africa far exceed naturalreplacement levels
    96. 96.

    101. 101. Making earth little softerWhat can be done about this?
    102. 102. Making earth little softerEmerging pattern• The balance between human demand andavailability is precarious• Access to clean water is not always guaranteedwhen it should be a fundamental right• Pop’n growth especially in the third world meanprospects are not good.• UNs world water development report
    103. 103. Making earth little softerMillennium Development Goals• In 2000 had a target to halve by 2015 theproportion of people without access tosustainable water supplies• By 2005 only 12% of developing countries hadmanaged to do this• In some LEDC’s fresh and waste water aren’teven separated. (Cholera and dysentery)
    104. 104. Making earth little softerHow water is used• In the western US, irrigation makes up 85% ofall water use• 50% to grow food for livestock• 35% to grow crops• Not sustainable…cost of water is heavilysubsidized by the federal government
    105. 105. Making earth little softerKey Areas-Direct Operations• Virtually all business organizations utilize waterin the production of their goods & services, theextent of use varies• For instance, water-infrastructure companiesplay a direct role in working with governmentsand municipalities to manage water andwastewater systems.• In other cases, water is a primary ingredient inan organization’s final product. Water is alsocrucial in the manufacturing or developmentprocess of many companies. In still others,water is a primary resource in the supply chain.
    106. 106. Making earth little softerKey Areas-Direct Operations• In areas of water stress, rapid industrializationplace significant demands on water resources.• Therefore, we pledge to undertake the followingactions as appropriate & during the period1.Conduct a comprehensive water-useassessment (audits) to understand the extent towhich the company uses water in the directproduction of goods and services.2.Set targets for operations related to waterconservation and waste-water treatment,framed in a corporate cleaner production andconsumption strategy.
    107. 107. Making earth little softerKey Areas-Direct Operations3. Seek to invest in and use new technologies toachieve these goals.4. Raise awareness of water sustainability withincorporate culture.5. Include water sustainability considerations inbusiness decision-making – e.g., facility-siting,due diligence, and production processes.
    108. 108. Making earth little softerWhat have we learnt• There is no life without water• Extremely small % of fresh & usable water isavailable for human being out of total stock• That water is a global issue and not just withincertain countries• That lack of water is not the only issue, but alsowater insecurity and water stress• Access to sanitation is linked to poverty• Development can hinder water quality, accessand supply• Using water carefully could minimize thescarcity
