Discrimination

This morning, we watched a vedio about discrimination.
In 1984,Jane Elliot did an experiment about discrimination. She divided her class in 2 groups. 1 group was blue eyes,another group was brown eyes. She told her students that blue eyes were better than brown eyes in the first day, and the blue eyes students did well in their test. However, the blue eyes students stated discriminate to brown eyes students. On the second day, she switched them , she said that brown eyes are better than blue eyes. On the third day, she told them there was no diference between them, they are same. Also, she found hes students' mark got better.
In my opinion, discrimination is normal. If we want to stop it, we need spend a long time, becaus it is according to many facts, such as culture, history and so on. From this vedio, it tell us dont judge people from there apperarance, we should judge inside.
