Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How long is one day at the North Pole?

The Big Idea

One day at the North Pole lasts a whole year! There is only one sunrise and one sunset each year. It sounds strange, but it is true. Let's follow the Sun.

Sunrise in March

Step one: sunrise in March. The Sun rises around the March equinox. After that, it climbs a little higher each day. That is the start of polar day.

Six Months of Day

Step two: six months of day. The Sun stays up for about six months, circling around the sky. It never dips below the horizon. Day after day, it just keeps going around.

Sunset in September

Step three: sunset in September. Around the September equinox, the Sun sets. Then comes about six months of night.

A Closer Look

Let's take a closer look! The Sun peeks up once. Then it circles for about six months. It sets once. And then it stays dark for about half a year. So a polar day lasts a whole year. Sunrise to sunrise takes a year.

Quick Facts

Quick facts! A person at the pole sees the Sun come up and go down only once a year. The Sun appears to circle the sky, not rise and set. Scientists at the pole follow clocks, not the Sun. Talk about time zones with a grown-up. A day at the pole means a year of light and dark.

Think Like a Scientist

Now, think like a scientist! Draw a circle for a year. Shade half yellow for polar day and half blue for polar night. Add a dot for the pole. Show how one day lasts a whole year.

Outro

At the North Pole, one day lasts a whole year. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
