The author, a reception/year 1 teacher at Maesycwmmer Primary School in South Wales, considers the holistic learning experience and his reflections on grouping and its impact. He says if primary science practitioners want science to be open and available to all, they need to think about how they make the subject accessible and subsequently differentiate to ensure this happens. However, this should not be at the risk of damaging the wellbeing of those they teach. They need to think about the whole child -- all of their strengths and weaknesses.
