Students participating in the Global Chemistry Experiment “Water: A Chemical Solution”
With over 470 schools registered and more than 10.000 students participating worldwide, the Global Chemistry Experiment is truly the largest chemistry experiment ever made.
The Global Chemistry Experiment “Water: A Chemical Solution”, which consists of four component activities, is a cornerstone activity of the International Year of Chemistry. The activities provide students with an appreciation of chemical investigation and data collection and validation. The results submitted by the students are available online as an interactive global data map - demonstrating the value of international cooperation in science.

On the occasion of UN World Water Day, 22 March 2011, UNESCO and IUPAC launched the International Year of Chemistry (IYC) Global Experiment (the “Big Splash”). For the event, 1,000 students aged 15 to 18 tested water quality in the Cape region of South Africa from 22 to 25 March, measuring salinity and acidity, and learning how it is filtered and distilled.
Engineer shortage a threat to development, underlines UNESCO’s first global report on engineering
More than ever, the world needs creative engineering solutions to face its biggest challenges, from poverty to climate change. Yet many countries are seeing a decline in the enrolment of young people, especially women, in engineering studies. The slump endangers future engineering capacity, particularly in developing countries where brain drain is an additional problem.
