Tropical rainforests support the greatest diversity of living organisms on Earth. In this activity, Rainforest Arrangers, from the Eden Project, your pupils begin by discussing the conditions in a tropical rainforest. Later researching the characteristics of living things that make it home. They are then tasked with summarising and sharing information with the class before grouping the organisms. Finally, they are presented with new information and given the opportunity to reassess their groupings during a round of ‘classification bingo’. These lessons are designed to promote discussion and exploratory talk.
