Why Does Water Turn Into Ice?

Imagine you are running around a playground. You move fast and bounce off the swings. When you get tired, you slow down and hold hands with your friends to make a circle. That is what water does when it freezes! Water is made of tiny particles called molecules. They usually run around freely in liquid water. When it gets cold outside, these molecules lose their energy and start moving slower. Eventually, they lock together into a special pattern called a crystal lattice. This locked group feels hard and solid to you because the molecules can no longer slide past each other. You know this happens when your drink has ice cubes in it or when roads get slippery after snow.

Think about how fast things move based on temperature. Hot water molecules zoom around like crazy children. Cold ones shuffle along slowly. Freezing is just the moment when they stop zoning and settle into place.

You might wonder why ice cubes float in your glass instead of sinking to the bottom. This happens because the crystal pattern holds the molecules a bit farther apart than they are in liquid water. This makes ice less dense, so it stays on top! It is like building a tower with blocks that creates empty spaces inside.
