The topic 'Animals including humans' runs through the primary science National Curriculum in England (DfE, 2013). Ideally, topics such as inheritance will lead onto adaptation, natural selection and evolution across key stages 1 to 2 (ages 5-11). This article provides nine engaging activities to support the teaching of adaptation and improve children's skills in observation, discussion and classification (grouping). The activities have not been arranged in any age-related order because they can be adapted and used for children across both key stages 1 and 2. Several additional resources have been listed at the end. The activities described encourage children to observe and make comparisons and support their understanding of classification.
