"MyScience" is a primary science education initiative in which being in a community of practice (CoP) is integral to the learning process. Stakeholder groups--primary teachers, primary students and scientist mentors--interact around the CoP "domain" of investigating scientifically and learn from each other "through participation." This paper is the fifth in a series and reports 27 year 5/6 students' (from three schools) perceptions of how their views were influenced through their involvement in a "MyScience" CoP. Semi-structured interviews, guided by a phenomenographic framework, were the substantive data source. Primary students' perceptions about science, science learning and science teaching were analysed using attributes associated with both "communities of practice" and the "nature of science." Findings reveal that students' perceptions of what it means to be "doing science" were transformed through their participation and students were able to identify some of the contributing factors. Where appropriate, students' views were compared with the published views of their participating scientist mentors and teachers from earlier papers. Implications for science teaching and learning in primary school community of practice settings are discussed.
