Knowledge organiser - Rainforests - Year 5

The Year 5 Geography knowledge organiser provides essential information about rainforests, a vital biome, and the rich biodiversity they support. The term 'biome' refers to distinct biological communities that have developed due to a shared physical climate. The rainforest biome is characterised by its dense and layered structure, starting with the 'canopy', which is a thick layer over 30 metres above the ground, formed by the interlocking branches and leaves of trees. Beneath the canopy lies the 'understory', a complex network of shrubs, young trees, saplings, palms, and vines, all competing for sunlight and space.

Biodiversity is a key concept in understanding rainforests, highlighting the incredible variety of plant and animal life found within this particular habitat. Rainforests are typically found in regions with mild, or 'temperate', climates and are known for their significant role in the global ecosystem. The knowledge organiser also touches on the critical issue of 'deforestation', where forests are cut down and the land is permanently repurposed. Students are expected to grasp what creates a rainforest, its global locations, and the importance of each layer, including the canopy and understory. Additionally, they will learn why rainforests are essential to protect, considering their ecological and climatic influence. This foundational knowledge sets the stage for understanding the main learning theme of rainforests in their Geography curriculum.
