How does a groundhog survive winter in its burrow?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How does a groundhog survive winter in its burrow?

The Big Idea

Groundhogs do not just sleep through winter. They hibernate deep in their burrows! Their bodies slow way down.

Eat Up

Step one: Eat Up. A groundhog eats a lot in the summer and fall to build up body fat. That fat is its fuel for winter.

Go Deep

Step two: Go Deep. Then it goes into a deep burrow below the frost line and hibernates. Its heartbeat slows to just a few beats a minute.

Slow and Cool

Step three: Slow and Cool. Its body temperature drops close to that of the soil. It lives on stored fat until spring, when it wakes up and comes out.

A Closer Look

Let's take a closer look! It eats a lot in fall. It digs into its burrow. Its heart slows way down. It wakes up in spring.

Quick Facts

Quick facts! A groundhog can lose a third of its weight over the winter. Groundhogs are also called woodchucks. Groundhogs are expert diggers with strong claws. Groundhogs eat plants, like grass and clover.

Think Like a Scientist

Now, think like a scientist! Make a graph of how a groundhog's weight might change. Show summer, fall, winter, and spring. When is it heaviest? When is it lightest? Explain your graph to a grown-up.

Outro

A groundhog survives winter by eating lots in summer and fall, then hibernating in a deep burrow below the frost line, with its heart and body slowed down, living on stored fat. Science is amazing! The world under your feet is full of surprises. Keep digging into big questions, and keep exploring with me! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books.
