Wonderful Water

Today we're going to learn and explore the different uses of water. As you already know, water has several different uses, all as beneficial as the other. Water can used to drink (however, we can only intake fresh water or else we are at risk to the consumption of dangerous bacteria's etc.),to cook with (eg. pasta tea etc.), to clean (brush teeth, mops floors etc.), the agricultural industry (watering plants, feeding of animals), to produce electricity (by using the force of water.),for recreational activities (sailing, swimming etc.), a habitat (for sea creatures) and for factory use (the cooling down of machinery.)

Some fun facts about water:

  • - water is made up of the two elements, hydrogen and oxgen = H2O
  • - water is essential for life on earth
  • - 70% of the earth is made up of water
  • - the freezing point of water is 0 degrees celcius
  • - the boiling point of water is 100 degrees celcius
  • - pure water is tasteless and odourless
  • - it's pH level is 7 (neutral)

    As I have previously said, water is vital for human survival. The body can survive for 3 weeks without food. However, it can only survive for 3-5 without water. A man's body is made up of 60-65% water. A woman's body is made up of 50-60% water.
