Final answer:
Jane Elliott conducted her famous blue eye-brown eye demonstration with third-grade students, to teach them the effects of discrimination and prejudice.
Step-by-step explanation:
Jane Elliott performed her famous blue eye-brown eye demonstration with third-grade students. The demonstration was intended as a practical lesson in discrimination following the assassination of Martin Luther King Jr. Elliott's exercise classified her students into two groups based on an arbitrary physical characteristic: eye color. This led to a powerful, firsthand experience of prejudice and minority treatment for the young children. The exercise has become a notable example in the field of social psychology and education, demonstrating the ease with which bias can be learned and the impact it can have on behavior and performance in children.
