This thesis takes its departure in 15-year-old students’ learning about the human body. During a semester I followed most of the sciences taught in one class of grade 9 students. I have chosen to illustrate lessons and analyse using the influence of feminists perspectives different situated actions in this science classroom practice, thereby raising a number of didactic questions focusing on the limits and possibilities of school science teaching. With the help of different analytic tools I have made close readings of transcribed situations presented in four studies.

The results show ways in which science content becomes relevant to students’ experiences, but also how students’ unique voices may shift focus from the expected science content. Overall, the results show how some discursive performances that are often taken for granted in science education are filled with explicit and implicit norms about how things should be for example in relation to femininity and masculinity. These performances may affect how students come to regard themselves and the world around them. However, the results also point out opportunities for changing these discursive performances. One way of doing this, which emerges from my results, is to create possibilities for acts in situations of equal subject positions, where different kinds of positions are welcomed. This is an approach where the content of science education involves and transforms the experiences of students’ social lives, where students’ actions in encounters with the differences are regarded as an important part of meaning making. Therefore, I suggest that ongoing negotiations in teaching should be taken into account, be regarded as a significant part of the learning processes and, through this, open up new possibilities of widening what kind of meaning making becomes available for the students. This, in turn, may create a space with unimagined ethical opportunities by paying attention to disparities, i.e. to others who may act from a different logic than we are used to, in other words: welcoming and involving differences.
