Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How did travelers find their way across the desert before maps and GPS?

The Big Idea

Before maps and GPS, desert travelers found their way by reading the sky and the land! They followed the North Star at night and the Sun by day. They also remembered landmarks and where to find water.

Follow the Sky

Step one: use the sky. At night, travelers followed the North Star, which stays in nearly the same spot in the north. By day, they watched where the Sun rose and set.

Read the Land

Step two: use landmarks. They used mountains and rock towers as landmarks. They even read the shapes of dunes, which line up with the wind.

Tools and Knowledge

Step three: share knowledge. Later, travelers also used compasses, which always point north. Most important, they carried knowledge of where to find water.

A Closer Look

Let's take a closer look! The North Star shows north at night. The Sun rises in the east and sets in the west. Mountains and rock towers help mark the way, like road signs. And a compass points north.

Quick Facts

Quick facts! Some desert dunes line up with the wind for hundreds of miles. Wind shapes sand in steady patterns. That is a clue travelers learned to read, just like a signpost. Never explore a desert alone. Go with a guide or grown-up.

Think Like a Scientist

Now, think like a scientist, with a grown-up! After dark, step outside and find the Big Dipper. Use it to find the North Star. Which direction does it point to? Share what you discover with a grown-up.

Outro

People used stars, the Sun, and the land to cross deserts. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
