The aim of this research was to examine the potential of project-based learning (PBL) and everyday life contexts in developing primary pupils' scientific and engineering practices. Multiple data were collected in a Finnish primary school class; pupils were aged 7-8 years. The pupils' practices and creation of artifacts were videotaped and analysed using theory-guided content analysis. The analysis revealed that the designed multidisciplinary PBL unit placed within a familiar everyday life context enabled pupils to practice and communicate scientific and engineering practices supported with digital technology.
