Lesson objectives ~
 To introduce the structure of the rainforest.
 To improve our literacy skills by learning
key words.
Let’s play word bingo!
Choose 4 words from the list below
and write them on your handout.
Buttress roots
Leaves with drip tips
Canopy
Lianas
Dark and Damp
Straight branchless
trunks
Dense undergrowth
Tall fast growing trees
Emergent
Layer of Humus
Feature
Label on diagram
Reason
Buttress roots
These are needed to stop tall trees from
toppling over.
Canopy
This layer has all the plants and animals
living in it.
Dark and Damp
It is very dark because the sun can, not get
through the intense vegetation.
Dense undergrowth
Is found in places where rivers flow or
trees have fallen and undergrowth has
grown.
Emergent
This is a tall tree, up to forty meters tall
living above the canopy layer.
Leaves with drip tips
Leaves have drip tips so that the rainwater
can fall straight off the leaves.
Lianas
These have adapted by looping around tall
trees so that they can reach the
sunlight.
Straight branchless
trunks
Trees don’t have branches because
branches waste the trees energy and
all energy is needed to grow tall.
Tall fast growing trees
Trees grow tall and fast to compete for
sunlight.
Layer of Humus
This forms quickly because of the damp
and hot conditions.
