WATER
Humans cannot taste water, but their impurities and the chemicals in it.
Water or H2o (chemical name) is made up of 2 hydrogen atoms and one oxygen atom.
Plants are 95 % water.
Humans are 65 % water.
Water can act as a solvent (can dissolve some solutes which are solid objects).
Plants absorb water through their roots and turn it into food. This process is called photosynthesis
Warm water can dissolve solutes faster!
On average the Tahuna WWTP treats 35million L of waste water every day and take cares of an average 80,000 residents every day.
Previously all the liquid waste from Dunedin was dumped into the Otago Harbour but now a waste water treatment plant has been built at Tahuna.
When we sweat, the heat from the sun evapourates our sweat and it cools us down.
Industrialised countries with a high GNI per Capita (income) generally have a higher percentage of people with access to safe water.
Humans take in an average of 3L of water every day through eating, drinking and respirating.
When wate freezes it is changing from liquid to a solid. And when water boils it changes from a liquid to a gas.
Water covers 75% of the worlds surface!
