How did the Great Explorers avoid getting lost at sea?

The Great Explorers used stars, watches, and maps to know where they were and not get lost at sea.

At night, the explorers would look up at the sky. They saw a special star called the North Star. It stayed in one place while other stars moved around it. This helped them find the direction of north, just like how you can use a compass to know which way is north.

They had big, ticking watches that showed time very accurately. By knowing the time and using the position of the sun or stars, they could figure out their latitude, imagine it like being on a number line for the ocean.

They also used maps drawn by other explorers before them. These maps showed land, water, and sometimes even dangers like rocks or storms. It was like having a treasure map that told them where to go next, just like you use your own map when you're playing a game of hide-and-seek!
