  1. What do we, the trees, and a hamster have in common? We all need water.
  2. Why all living things need water? To survive.
  3. What happen if we do not drink enough water? Our body would stop working properly.
  4. For how long we can live without water? For two days. Our blood contains a lot of water, carries oxygen to all the cells of our body. Without water those tiny cells would die and our body stop working.
  5. What else? Water is also in lymph, a fluid that is part of our immune system, which help us to fight illnesses. We need water to digest our food and get ride of wast.
  6. Water is needed for digestive juices, urine (pee) and poop, and sweat.
  7. Each cell depends on water to function properly.
  8. How much to drink? Expert believe we need 8 glasses of water each day.
  9. What is water? The hydrogen atoms are "attached" to one side of the Oxygen atom, resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side. We must thank Almighty for all the good things He has provided us.

We need to drink regularly so that we do not become dehydrated. It is good to know that 85 % of our body is water therefore when we have activities water evaporates and need to be replaced. In the Almighty' s kitchen the best water is the snow water. We have to drink eight glasses of water every day. Water must be at least body temperature, fresh and clean. Tea and coffees drains our body's water away, therefore if we drink a cup of coffee then we have to drink two glasses of water afterward. Fruits juice and the fizzy drinks must not be replaced with water. We must drink enough water every day.  We need to drink water from the sun raise to the sun set eight glasses per day. If we exercise we need to drink more water. Our blood become thinner when we drink enough water.


Water is good for our body. 85% of our body is water. We need to drink two liters of water each day. Clean water is a filtered water.





CLEAN WATER- it is important to drink a clean water. A clean water is free and clear from any kind of the chemical materials. Do not drink the tap water, either filter it or boil it before you drink. If you love yourself drink clean water. 



                            

               Tap water is not clean water            Filter water must be kept
                                                  in non plastic bottle


Water Purification- is the process of removing undesirable chemicals, materials and biological contaminants from raw water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water) but water purification may also be designed for a variety of other purposes, including meeting the requirements of medical, pharmacology, chemical and industrial application. In general the methods used include physical process such as  filtration and  sedimentation, biological processes such as slow sand filters or activated sludge, chemical process such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light. The purification process of water may reduce the concentration of particulate matter including suspended particles, parasites, bacteria, algae, viruses, fungi; and a range of dissolved and particulate material derived from the surfaces that water may have made contact with after falling as rain. The standards for drinking water quality are typically set by governments or by international standards. These standards will typically set minimum and maximum concentrations of contaminants for the use that is to be made of the water.  It is not possible to tell whether water is of an appropriate quality by visual examination. Simple procedures such as boiling or the use of household activated carbon filter are not sufficient for treating all the possible contaminants that may be present in water from an unknown source. Even natural spring water- considered safe for all practical purposes in the 1800s- must now be tested before determining what kind of treatment, if any, is needed. Chemical analysis, while expensive, is the only way to obtain the information necessary for deciding on the appropriated method of purification.

FILTRATION- is a mechanical or physical operation which is used for the separation of solids from fluids (liquids or gases) by interposing a medium through which only the fluid can pass. Oversize solids in the fluid are retained, but the separation is not complete; solids will be contaminated with some fluid and filtrate will contain fine particles (depending on the pore size and filter thickness).
