Titanic
The Titanic was a big ship that sailed across the ocean a long time ago. People thought it was
unsinkable, but something terrible happened. The ship started its journey with many passengers
on board. There were rich people and poor people, all excited about their trip. They had parties
and enjoyed the fancy rooms. But one night, the Titanic hit a big iceberg. The iceberg was
hidden in the dark water. The ship's crew tried to save everyone, but the water started filling the
ship. People were scared and confused. As the water rose, lifeboats were lowered into the ocean.
Some people got on the lifeboats, but not everyone could fit. It was a sad and chaotic scene. The
Titanic started sinking slowly into the cold water. People were in shock, holding onto anything
they could find. Many lives were lost that night. The Titanic's tragic story reminds us that even
the mightiest things can be unsafe. It's important to remember the people who were on the ship
and the lessons we can learn from that terrible night.
