For the International Year of Chemistry in 2011, the Scottish Local Sections of the Royal Society of Chemistry are co-ordinating Scotland-wide participation in the International Year of Chemistry Global Water Experiment.

The Global Water Experiment consists of 4 simple hands-on activities for you to carry out on a sample of rain-water:

•Measuring acidity •Measuring salinity (salt content) •Purifying water by filtration •Purifying water using the sun’s energy

All experiments have links to Curriculum for Excellence in science, social studies, health and well-being, technologies.

Results will be electronically showcased as an interactive global data map at the end of 2011, demonstrating the value of international cooperation in science.

Full instructions are available on the International Year of Chemistry website:
