Science Opens Doors is the creation of Clive Thompson of the Horners' Livery Company. The Science Opens Doors project philosophy is strongly based upon the King's College London ASPIRES project, which established that children like doing science in junior school (ages 7-11), but that by the age of 12-14 they are firmly against becoming scientists. The philosophy was also influenced by a Science Council study that identified the pressing need for people with science qualifications and highlighted that only a small proportion of scientists are laboratory scientists, with the majority working in a range of industries, professions, and services. Hence, the evolution of the project title and the emphasis upon "careers from science." The project creators decided upon a practical intervention strategy, Science Open Doors, involving the parents of young people who were less likely to aspire to science careers. Schools that have taken part in the pilot phase of the project have been chosen from areas that are traditionally seen as having children less likely to aspire to science careers. A Science Opens Doors event is aimed at year 5 children (age 9-10). This article describes one of the project events and how it sparked curiosity and interest beyond all expectations.
