Shark Island Shark Island is a small island located in Sydney Harbour‚ Australia. It lies between the Harbour Bridge and the harbour entrance‚ offshore of the suburbs of Vaucluse‚ Point Piper and Rose Bay. The Island‚ at 1.25 hectares‚ is said to have resembled a shark and the shallow waters around it presented a constant danger to shipping. This is how it got its name. Physical Environment of Shark Island Weather & Climate The weather on Shark Island that day varied a lot. It was overcast

Science Coursework-Rates of Reactions Introduction Investigating how the concentration of sodium-thiosulphate (STS) and hydrochloric acid (HCL) affects the rate of reaction in the experiment. In addition I am also checking how different variables affect my experiment and also how I can make my test more precise‚ reliable and accurate. Strategy According to my results‚ as the concentration of STS solution increased the rate of reaction of my experiment was increased. Also as the concentration

The water contains conducticity of less than 70 mS/m which indicates that the water has a very low concentration of pesticides‚ sewage and other harmful substances within the water showing that its safe for human consumption. The turbidity of the water is tested as being slightly salty (greater than 1ntu) but this is only a aesthetic property that won’t affect the waters purity nor the “healthiness” of the water.

How water is purified in water treatment plants Pre-treatment 1. Pumping and containment – The majority of water must be pumped from its source or directed into pipes or holding tanks. To avoid adding contaminants to the water‚ this physical infrastructure must be made from appropriate materials and constructed so that accidental contamination does not occur. 2. Screening (see also screen filter) – The first step in purifying surface water is to remove large debris such as sticks‚ leaves
