Internationally there is growing interest in how young children engage with and learn concepts of science and sustainability in their everyday lives. These concepts are often built through nature and outdoor play in young children. Through the dialectical concept of everyday and scientific concept formation (Vygotsky LS, The collected works of L.S. Vygotsky. Problems of general psychology, V.1, (Trans. N Minick). Editor of English Translation, RW Rieber, and AS Carton, New York: Kluwer Academic and Plenum Publishers, 1987), this chapter presents a study of how families transformatively draw attention to STEM and sustainability concepts in the everyday practices of the home. The research followed a focus child (4–5 year old) from four families as they navigated everyday life and talked about the environments in which they live. Australia as a culturally diverse community was reflected in the families, whose heritage originated in Europe, Iran, India, Nepal and Taiwan. The study identified the multiple ways in which families introduce practices and conceptualise imagined futures and revisioning (Payne PG, J HAIA 12:2–12, 2005a). About looking after their environment. It was found that young children appear to develop concepts of STEM, but also build agency in exploration, with many of these explorations taking place in outdoor settings. We conceptualise this as a motive orientation to caring for the environment, named as E-STEM. The study emphasises for education to begin with identifying family practices and children’s explorations, as a key informant for building relevant and locally driven pedagogical practices to support environmental learning.
