Bringing more girls and women into science, technology, engineering and mathematics, STEM, is often highlighted as an aim in education and industry. A constantly growing body of research on engagement is driven by equity concerns caused by the unbalanced gender distribution in STEM. In this study, Swedish teenage girls on a three-day technology camp are in focus. The camp was an initiative with three goals: “Get girls interested, keep girls interested and provide knowledge about futures within technology professions”. We explored the participating girls’ technological activities and conceptions of technology at the camp. Data collection was conducted through participant observations and a focus group interview. Data were analysed using thematic analysis and a gender theoretical framework. Results show the camp presented uncertain notions of what technology can be, and traditionally male-oriented domains were “girlified”. However, girlified activities might not have been constructive in this context since the girls expressed interest in technology before the camp and showed few signs of gendering technology – they liked all kinds of technology. Girlified technology can, at its worst, give a false image of the future industrial work life that the camp organiser aimed to inspire. Despite this, the camp activities were still meaningful and relevant to the girls. The camp created opportunities for the girls to develop their sense of being technical and a feeling of belonging. Implications for technology classroom settings and future camps are to value practical work and improvisational design without leaving the teaching unreflected. This could be a way of engaging and familiarising girls with the multifaceted world of technology without girlifying it. In addition, a broad conception of technology could make gender codes less relevant and open new opportunities.
