Caption: Science education. School children carry out a classroom experiment to measure the thickness of a leaf with a penetrometer. A cup fixed to a spike is gradually filled with water until the weight pushes the spike through the leaf. The photograph was taken at the Burnell Lab School in Bridgewater, Massachusetts, USA, where the experiment formed part of the 1994 JASON Project in which children from schools across the USA examined the relationships between insects and plants in the rainforest of Belize.
