Why do prairie grasses have roots deeper than the plants are tall?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do prairie grasses have roots deeper than the plants are tall?

The Big Idea

Prairie grasses look ordinary from above. But underground, their roots go very deep! Deeper than the plants are tall.

Deep Roots

Step one: Deep Roots. Prairie grasses like big bluestem can have roots reaching 10 feet or more underground. The tops reach only about 6 feet.

Finding Water

Step two: Finding Water. Deep roots find water during dry spells. They also hold the soil when strong winds blow.

Regrowing

Step three: Regrowing. If fire or grazing eats the leaves, the grass regrows from its roots. Most of the plant is underground, safe and ready to grow again.

A Closer Look

Let's take a closer look! Tall grass grows above. The crown sits at the surface. Roots go deep down. They reach deep water.

Quick Facts

Quick facts! Prairie roots built some of the richest farmland in the world. Bison once grazed across the prairies. Prairie grasses survive fires because their roots stay safe. Most of a prairie grass plant is hidden underground.

Think Like a Scientist

Now, think like a scientist! Draw a prairie grass with its roots. Use a scale, like one inch for each foot. Make the leaves 6 inches tall. Make the roots 10 inches long. Which part is bigger?

Outro

Prairie grasses grow roots deeper than they are tall to find water in dry spells, hold soil against wind, and regrow after fire or grazing. Most of the plant is underground. Science is amazing!
