When water gets cold enough, it turns into ice! That happens because the water molecules slow down and stick together in a special way.
Here's a breakdown:
-
Water Molecules: Imagine tiny LEGO bricks jiggling around; these are water molecules.
-
Cooling Down: When water gets colder, these LEGO bricks start to slow down. They don't have as much energy to move around.
-
Sticking Together: As they slow down, they start to stick to each other in a specific pattern. This pattern makes them take up more space than when they are jiggling around as liquid water.
-
Becoming Ice: When enough water molecules stick together in this pattern, the water freezes and becomes solid ice. That's why ice floats on water - it's less dense because of the special arrangement of the molecules!
So, ice freezes when water gets cold, the water molecules slow down, and they stick together in a special way to form a solid.
