Global Water Experiment
Within The International Year of Chemistry (IYC 2011) an initiative of IUPAC, the International Union of Pure and Applied Chemistry, and of UNESCO, the United Nations Educational, Scientific and Cultural Organization, school students around the world will be invited to explore one of Earth's most critical resources, water. The results of ther investigations will contribute to a Global Experiment, which will possibly become the biggest chemistry experiment ever.
The global experiment is an initiative of the IUPAC Committee on Chemistry Education- has been developed to appeal to students from primary school to senior high school. The activities that make up the experiment will help students appreciate the role of chemistry in issues of water quality and purification. At the same time, students will contribute to an online global map, reporting on their investigations of water quality and water treatment.
Note: For its use in the Visualization Sprint, we have cleaned up this data set and added geocoding and categorization (waterType and waterSource columns) - Visualizing.org.
The Global Experiment consists of four experiments:
Experiment 1: Acidity - In this activity students will be learning about acidity, one of the most common chemical properties encountered around the home. At the same time they will be learning good experimental techniques to test the reliability of their results.
Experiment 2: Salinity - This activity will give students the opportunity to use either a homemade or commercial meter to measure the conductivity of water samples. Students will learn about salts and determine concentrations of salts in solutions.
Experiment 3: No dirt no germs - In this activity students will use household materials to build a water filtration unit and identify the efficiency of different filtration materials. Then, as a follow up, they will carry out a treatment of the water.
Experiment 4: Solar still challenge - In this activity students will explore an alternative way of purifying water using a solar still, learning about the distillation process and the states of matter. The activity will provide students with the opportunity to design and build their own more efficient stills.
