This paper reports on and discusses one Scottish secondary school's attempts to develop an understanding of discrimination and prejudice with S1 (Year 7 in England) pupils using a simulation based on a truncated version of Jane Elliott's "Blue Eyes/Brown Eyes" experiment of the 1960s. The research questions were: (1) Did the pupils learn anything about discrimination from the day as a whole?; (2) Did they remember what they have learned over a period of time?; (3) Did the "winter babies" gain more from the day than the "summer babies"?; and (4) Was the experiment worthwhile? The paper first discusses the issue of using simulations in general and specifically with pupils aged about 12 years; second, explains how the simulation was set up; third, reports on the pupil perception of the simulation--both the "victims" and the "bystanders"; and fourth, attempts to draw some tentative conclusions.
