Scientists from a Royston school have been put on the map to celebrate Chemistry Week 2013.

The pupils from Greneway Middle School in Royston were visited by Lee Page and Sue Thompson from the Royal Society of Chemister.

A spokesman for the school said: “They guided the students through a series of tests to test how much vitamin C is in red peppers and apples.

“The data was plotted on to an interactive map and compared with students around the world.”
