Transcript of "Omari"

  1. 1. WATER Water is essential in our lives. It is considered as a universal solvent. Do you know that the human body consists of 70% of water? Water can be a liquid, a solid, or a gas. Liquid water flows. Solid water is ice. Water in the form of a gas is called water vapour. WHERE IS WATER FOUND ON EARTH? Liquid water fills the ocean, lakes, ponds, rivers, and swamps. Water droplets form rain clouds. Liquid water makes beads of dew on the grass. It seeps down into the ground. It fills underground lakes and streams. Ice falls as hail or crystals of snow. Ice forms on ponds and frosty windowpanes. Huge sheets of ice make glaciers and icecaps at the North and South poles. Water vapour is always present in the air. Water vapour makes clouds in the sky. Water vapour makes fog that hangs close to the ground. It is the steam that comes out of a teakettle. CONSTITUENT OF WATER Water is made up of two elements i.e. hydrogen and oxygen. Water is considered to be a universal solvent because of its capability of dissolving many substances.
  2. 2. PROPERTIES OF WATER  It is colourless.  It has a high surface tension.  It is odourless. DO YOU KNOW HOW TO TEST FOR WATER? HERE ARE A FEW WAYS:  It is neutral to both red and blue litmus paper and has pH of 7.  It turns white anhydrous copper (II) tetraoxosulphate (IV) to blue Water consummation HOW DO WE CONSUME WATER? Water is consumed in many ways; here are a few points; o DOMESTIC PURPOSES: water is used for cooking, drinking and washing in our homes. It is sometimes left running in the sink which wastes water. o INDUSTRIAL PURPOSES: water is used to prepare chemicals and solutions. o ENERGY PRODUCTION: water is used to turn turbines to produce electricity (hydroelectric power). o AGRICULTURAL PURPOSES: used for irrigation of farmlands for growth and development of plan.

CAUSES OF WATER POLLUTION 1. Oil spillage: Tema being one of Ghana’s industries cities has many industries whose waste products are mainly oil. This mostly occurs during the production, distribution, and refining stages. These oil spills enter oceans and rivers from faulty and accident tankers as well as offshore oil wells.
  4. 4. 2. Untreated sewage from plants, animals and humans. 3. Bad mining practices: Because mining is one of Ghana’s major activities, there are usual discharges from mining sites in the form of acid mine-water and also acid rain contribute to water pollution. EFFECTS OF WATER POLLUTION  It leads to the increased in water borne diseases. Water-borne diseases are infectious diseases spread primarily through contaminated water  Water pollution poses a number of health problems How would you solve these problems in your locality? SOLUTIONS TO THE PROBLEM OF WATER POLLUTION a) Raw sewage should be treated before discharged. b) The Municipal Assemblies and the other assemblies should provide rubbish cans so that rubbish empty tins and plastics can properly be disposed off. c) Education: the government must educate people on the need to keep their water bodies clean. This can be done through the use of the media, forums and programs. For it is when we THINK GLOBALLY that we can ACT LOCALLY. Water is never safe for drinking. Water undergoes several processes before distributed to people for use. Some of these processes are; Oxidation Filtration Coagulation Sedimentation Chlorination WAYS THROUGH WHICH WATER IS STORED IN GHANA DAMS AND RIVERS: We build dams to control water. A dam built across a river or stream stops the water’s flow. Water collects in a lake behind the dam. The lake stores water for people to use later. The lake, or water storage area, is called a reservoir.
