Botanical Garden takes part in Global Water Experiment
04 July 2011 by Bert van de MeijdenAs part of its contribution to the Global Water Experiment, on 26 and 27 May, TU Delft’s Botanical Garden organised a workshop for a hundred Delft schoolchildren in the last year of primary school. The Global Water Experiment is a UNESCO and IUAPC initiative in the framework of the International Year of Chemistry 2011.
Experiments
The aim of the Global Water Experiment is to involve school pupils and students from across the world in testing the quality of water by means of four different experiments involving pH measurements, salinity measurements, filtration and disinfection, and desalination. The school students conducted the first experiment, the pH measurement, in the garden.
pH value
The school pupils were able to bring along their own water samples or use water from the garden. PH measurements were taken for two of the samples from the garden. One of the samples, from surface water, with a pH value of 7.5, was entered into the world water database http://water.chemistry2011.org/web/iyc http://water.chemistry2011.org/web/iyc.
Alliance
The Botanical Garden’s initiative was realised in alliance with TU Delft/AS/Biotechnology department, the municipality of Delft and the C3 Foundation (which promotes chemistry among young people).
