Can Chemistry be the solution to face the challenge of diminishing drinking water supplies worldwide? Does the water we drink differ in different regions around the world?

IUPAC and UNESCO have developed a set of experiments (acidity, salinity, filtration, distillation) for pupils of different ages to analyze the quality of water and learn how to treat their local water sources. Children all around the world will have the opportunity to upload the results of their investigations to an official website, making this initiative a Global Chemistry Experiment, and eventually, the biggest chemistry experiment ever.
