  2. 2. PROBLEM2.2 million people in developing counties, most of them children, die every year from diseases associated with lack of access to safe drinking water.Half of the worlds hospital beds are filled with people suffering water related illness.
  3. 3. RESEARCHIf you put a clean cloth in a cup and pour water in it, the cloth will purify some of the water.Women spend 200 million hours a day collecting water from water holes.Only 10 percent of of our waste is treated the rest of the waste goes into our lakes, rivers, and oceans.
  4. 4. RESEARCHThe five steps of purifying water that the United States use are: Coagulation, Sedimentation, Filtration, Disinfection, and Storage.The water passes through filters, some of the filters are sand, charcoal, and gravel.Coagulate means to cause a fluid to change to a solid or semisolid state.Sediment means matter that settles @ the bottom of the liquid.Filtration means it’s the process of filtering something.

  7. 7. EXPERIMENTIf there’s salt in the water it will Most of the water is boil at a high temperature. poisons.If there’s minerals in the water it will boil at a low temperature.If I was in a different country I would boil tap water because it boils faster and doesn’t have salt in it.I would boil the water in a metal container because it boils faster than glass container and metal conducts heat.
  8. 8. CONCLUSIONWe learned about all the steps of the water treatment plant.Water that is polluted can kill other people.Only distilled water boils @ 1000C and freezes @ 00C.Other water that has different physical properties boils and freezes @ different temperatures.People in other countries are forced to drink polluted water.
