Intro
Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do a few rainforest trees poke up above all the others?
The Big Idea
Trees in the emergent layer stretch up 150 feet or more, which is 45 meters, to catch the brightest sunlight. They also catch the breeze that carries their pollen and seeds. A gap in the canopy gives them a chance to grow toward the light.
Race for Light
Step one: a race for light. When a gap opens in the forest, a young tree grows slowly toward the bright sky. The tallest ones win the most sunshine.
Wind and Seeds
Step two: the breeze. Up high, the wind carries pollen and seeds far away. This helps these giants make new baby trees.
Tough Leaves
Step three: tough leaves. Up top, trees face strong wind, heat, and sun, so their leaves are small and tough. Big birds, like eagles, sometimes nest in these tall trees.
A Closer Look
Let's look up high! The sunshine is brightest at the very top. The breeze carries pollen and seeds. The leaves are small and tough. And eagles may nest in the branches.
Quick Facts
Quick facts! Some emergent trees are taller than a 15-story building. A tree 150 feet tall is about 45 meters. They grow slowly toward light when a gap opens. Measure outdoors with a grown-up in a safe place.
Think Like a Scientist
Now, think like a scientist! Measure your height with a piece of string. Stretch the string across a playground, with a grown-up. Count how many of you equal a 150-foot tree. That is a very tall tree!
