Social justice and equity are important elements of all educational services and particularly in early childhood where there is an emphasis on including all children in the everyday life of early childhood settings. This emphasis has targeted both the policies and practices in early childhood to meet the needs of a diverse range of learners. An outcome of policy reform is the emphasis on inclusive education that is based on the right of all children to access and participate in general education. A critical pedagogy approach counters discrimination by promoting positive attitudes towards diversity. Science learning is important for all children as it is an approach to thinking and behaving that incorporates aspects of motor, behavioural, sensory, communication and mental functioning. Children from diverse situations can contribute at their own level to the opportunities involved in exploration and investigations. This paper discusses inclusive pedagogy and planning in early childhood centres with a particular focus on science learning through play and child-instigated explorations.
