Ecosystem changes in a pond

This resource builds on students prior understanding of the biotic and abiotic parts of the pond ecosystem, to develop critical thinking skills or thunks. This resource present series of scenarios where man-made or natural actions cause an element of change in the pond ecosystem and food chain. Students must annotate their blank pond diagram, like the example shown, in order to likely or possible changes that happen as a direct or indirect result. This flexible activity could be done as a starter, in pairs or larger groups. Possibly as a carousel revision activity, or as a stimulus for an exam response. I would encourage students to share their annotations with the class and explain why they think these things will happen. Links with the ‘Living World’ aqa GCSE Geography specification.
