Global chemistry experiment for Cape Cornwall pupils
PUPILS from Cape Cornwall School took part in the world's biggest water testing experiment last week, helping to provide a picture of the planet's pH levels.
Children from Years 7 and 8 took samples from Kenidjack River in St Just at the same time thousands of youngsters tested the acidity of their local of rivers, lakes and waterways across the world.
The experiment, the brainwave of experts at the Royal Society of Chemistry (RSC), was the largest single collection of data on water quality ever undertaken at one time.
Science teacher Natalie Lewis explained Cape Cornwall students tested the pH and salinity of the river before purifying it using a solar still and homemade filtration unit.

She said: "This was an amazing opportunity for pupils from Cape Cornwall School to be involved in a chemistry experiment on a global scale."
The Global Experiment is the centrepiece of the International Year of Chemistry 2011, established by the UN to mark the 100th anniversary of Marie Curie winning the Nobel Prize for Chemistry in 1911.
By conducting the pH tests, students will contribute to an online global 'map' of water quality and treatment.
RSC president, Professor David Phillips, said: "This remarkable initiative will demonstrate the enjoyment gained from practical experimentation.
"We believe the results will also provide a picture of global pH that will be very informative.
"So the work by students all over our country, and in others where the experiment will be taking place on the same day, is of genuine national and international use."
