As IB students we have been tasked to carry out tests for pH, electrical conductivity, boiling point, and water hardness on water samples taken from the rainwater catchment area underneath the school. There were four water samples, the first one was taken from underneath the volleyball court, the second from junior school, the third from the garden well, and the fourth from the hall. Since we were a group of three, each sample’s pH, conductivity, boiling point, and water hardness was tested three times. Carrying out multiple tests on each sample allowed us to pool the data that we collected and establish reliability of the data.
