Biography Fair has its roots in so many Riverside traditions but one is rarely as captivating as Bio Fair. Students start thinking about it during the first week of school. And the day it arrives, you can hardly recognize the middle school students on campus. Their costumes so elaborate and the displays so detailed. The students are even overheard speaking to each other in character. The elementary students even catch the bug by performing short speeches and interviews in their characters and all the students act as audience to one another while proud parents look on.
