The attitudes of Year 5 primary-school children towards science, engineering and technology (SET) were examined prior to studying the effects of the Horsham Greenpower Goblin Challenge (HGGC), a hands-on SET project. The data collection centred on pupil, parent and teacher questionnaires using Likert scales and picture/word images of scientists and engineers. Analysis showed that Year 5 children had definite, discrete images of SET, seeing science as investigative, engineering as repairing and technology as creative. In general, the children enjoyed science and design technology at school and appreciated the benefits of science and engineering to society, but did not wish to become scientists or engineers.
