How to use a sextant?

A sextant is like a super-powered ruler that helps you measure angles between things in the sky, just like you might use a ruler to see how tall your favorite toy is.

Imagine you're playing with building blocks, and you want to know how far apart two blocks are. A sextant does something similar, but up in the sky! It lets you figure out how far away the sun or moon is from the horizon, which helps you find out where you are on Earth.

You hold the sextant like a little telescope and look through one side. Then you move a mirror until the image of the object (like the sun) lines up with the horizon. The more you move that mirror, the bigger the angle, just like how your arms stretch wider when you make a bigger “V” shape.

When sailors used to go on big adventures across the ocean, they’d use a sextant to figure out their position by looking at the sun or stars. It’s like having a special map that helps you know where you are, even when there are no landmarks around!
