In this study, we investigate how young students can make use of their own disciplinary drawings to support transitions between everyday and scientific discourses of water. The empirical data consists of video-recorded stimulated recall interviews with six student pairs (age 8 years), conducted six months after they had been introduced to a water theme that included disciplinary drawing techniques. During the interviews, we provided students with their drawings as recall material. To stimulate a stalled discussion further or to support a new line of thought, we also asked supporting questions and provided the students with plastic models of water molecules, and a bottle of water. To trace their reasoning over time during the interview, the empirical material was used to construct semantic profiles for all student pairs underpinned by Legitimation Code Theory (LCT). Our findings show that most students used their drawings to bridge everyday experiences and scientific explanations of phenomena involving water. The plastic models and the water bottle however had varying effects, sometimes leading to adding a scientific discourse, and sometimes leading to off-topic reasoning. The students generally needed adult guidance to use their own drawings for navigating between everyday and scientific reasoning. However, our findings also show that some students were able to independently use their drawings to move between everyday and scientific discourse, in a way that suggests a gradual deepening of their understanding of the chemical properties of water. Based on these findings, we advocate for emergent disciplinary drawing, in combination with guided discussions, as an age-appropriate method for supporting primary students to navigate between everyday and scientific discourses in chemistry class. This approach could ensure that the educational value of students' creative efforts when drawing extends beyond the moment of creation, to also foster a richer language that can open for new ways of understanding and making sense of the world.
