Why Don’t Reindeer Follow a Day-And-Night Clock in the Arctic?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why don’t reindeer follow a day-and-night clock in the Arctic?

The Big Idea

Scientists found that reindeer in the Arctic do not have a strong 24-hour body rhythm! Instead of following day and night, they eat and rest in short cycles. Let's follow the herd.

Body Clocks

Step one: body clocks. Many animals have an inner clock that follows a 24-hour day. It tells them when to sleep and wake. But reindeer do things differently.

Reindeer Rhythm

Step two: reindeer rhythm. Reindeer in the Arctic do not have a strong 24-hour rhythm in summer or winter. They eat and rest in short cycles, whenever they need to.

It Works

Step three: it works. That works well when the Sun does not rise or set for months. Their eyes change color with the seasons, too.

A Closer Look

Let's take a closer look! Reindeer, also called caribou, roam the Arctic. They eat plants like lichen, moss, and grasses. Then they rest while their stomachs work. They repeat that all day and night. Their rhythm is flexible.

Quick Facts

Quick facts! Reindeer eyes change color between summer and winter. Their short eat-and-rest cycles are tied to digesting tough plants. Their rhythm is flexible, so they can eat whenever food is around. Watch wild animals only from far away, with a grown-up. Flexible schedules suit a land of endless day and night.

Think Like a Scientist

Now, be a detective! With a grown-up's okay, keep a diary for an afternoon. Write down when you eat, play, and rest. Is your schedule like a reindeer's or like a clock's? Compare it with your normal routine.

Reindeer eat and rest in short cycles instead of following a clock. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
