This paper provides an in-depth, "case study" style analysis of the experiences of two 13-year-old British Asian girls from a larger qualitative study investigating minority ethnic students' aspirations in science. Through the lens of identity as performativity and Bourdieu's notions of "habitus" and capital, the ways in which two girls engage with the field of science is examined. Samantha is British Indian and Fay is British Bangladeshi and they are both "top set" students in science, but only one aspired to study triple science, while the other desired to be "famous". The experiences of the two girls are explicated in this paper, teasing out their experiences and constructions of science. It is argued that cultural discourses of family, peers and teacher expectations can shape students' perceptions of science and education. (Contains 10 notes.)
