Rainforest Layers

Science · Rainforests · conceptual

Know that a rainforest has four layers from ground to sky — the forest floor (dark, damp, full of decomposing leaves), the understory (small trees and shrubs in the shade), the canopy (a thick roof of treetops where most animals live), and the emergent layer (the tallest trees poking above the canopy into bright sunlight)

What mastery looks like

  • Name the four rainforest layers in order from ground to sky: forest floor, understory, canopy, emergent
  • Describe one key feature of each layer, such as the canopy being a thick roof of leaves or the forest floor being dark and damp
  • Explain that most rainforest animals live in the canopy because that is where there is food and light

Check your understanding

If Rainforest Layers draws a rainforest, can they show the four layers — the dark forest floor, the shady understory, the leafy canopy, and the tallest emergent trees poking into the sky?
