Water Scarcity & the Importance of Water Introduction: This report has been written to inform you of the world water crisis which is getting worse every second. It has also been written to inform you about the water scarcity and importance. Water Scarcity and importance: Clean‚ safe drinking water is not easy to find any longer. Today‚ nearly 1 billion people in the developing world don’t have access to it. Yet‚ we take it for granted‚ we waste it‚ and we even pay too much to drink it from little

Water Filtration There is a wide range of filtration methods currently being used all over the world. Some can be dangerous to handle and very reactive while others can be used in an any day household. Although no filtration method is perfect‚ combining different forms of filtration can provide near-perfect water. One note to take is that most of the time the more that is filtered‚ the pricier the method is. Three very effective methods of water filtration are “Ion Exchange”‚ UV light‚ and

Water and me Water is a colourless‚ transparent and odourless liquid which forms the seas‚ lakes‚ rivers‚ and rain and is the basis of the fluids of living organisms. It is a chemical compound whose formula is H2O. It covers 71% of the earth’s surface and is necessary for every known organism to live. 97% of the total water found on the earth lies in the oceans. The rest of water is in the form of glaciers and ice caps (2.1%)‚ ground water (0.6%)‚ inland water (0.2%) and water vapours (0.001%).

Ice will melt just as fast the water will freeze. You won’t see the melting and freezing processes as long as they are balanced and equal. Adding salt or any foreign substance to the water upsets the fragile equality between freezing and melting. Less of the water molecules reach the surface of the ice in an amount of given time. The

Topic 6 Water Quality and Water Management What determines water quality? Drinking water should be colorless‚ odorless and flavorless; this means that there are no organisms and sediments in the water‚ but it does not mean that if your drinking water look‚ smells and taste clean‚ that does not mean that there is nothing else it. Water also contains dissolved solids: •Sulfur •Calcium •Magnesium If water contains a lot of dissolved calcium and magnesium it is called hard water

On this World Water day March 22nd 2006‚ Let’s pledge to Save water . Remember Water is Life. BABA’s Life. Lets start from World Water Day and implement it every day ‚ every minute in our daily life.... If Your are ready to to join me. Make sure and educate all your friends/relatives to save water. If lakhs of people start this simple practice‚ we will surely make a BIG difference... GENERAL WATER SAVING TIPS 1. Create an awareness of the need for water conservation among your children

needs water to survive. Water is our most important resource that is required to ensure our survival. This resource is something that we use every day in our lives and it serves many different purposes. We use water to take showers‚ to flush the toilet‚ cook dinner‚ to drink‚ and to clean. Water is not only used for our domestic needs‚ or wants but it is used in agriculture‚ industries‚ transportation‚ and as an alternative energy source (Lenntech‚ 2008). Life would be impossible without water. All

determine how an excess amount of liquid‚ which was water‚ Gatorade and wine in this case‚ along with an excess amount of solute‚ which was the 7g NaCl pill‚ would affect the kidneys and the osmolarity of urine. Measurements of urine volume‚ specific gravity and chloride concentrations were recorded in order to investigate this. Our hypothesis stated that the volume of urine would increase for all groups other than the group drinking 80 ml of water along with taking a 7g. This portion of the hypothesis

My Science Project Can water float on water? My Prediction I predict that water can’t float on top of water. Simply because it sounds impossible‚ but it will be interesting to find out if however it is possible. The Experiment First‚ I found two 1litre bottles and marked one with ‘+ salt’ and the other with ‘fresh’. I then went on to add red food colouring to the fresh bottle and yellow to the + salt bottle. The reason for doing so was to establish which ones were which and see if they
