Water is a master of disguise: it changes shape without changing its nature.
🧊 Solid
In the freezer, water freezes and becomes ice. You can hold it in your hand.
💧 Liquid
Let an ice cube melt: it takes the shape of the glass! That's liquid water.
☁️ Gas
When water boils, it becomes invisible steam. Put a cold lid on top: condensation appears.
🤯 Did you know?
Water is one of the few substances that takes up more space when it freezes! That's why a full bottle can burst in the freezer. And an ice cube floats instead of sinking.
The scientist's words
Melting: solid → liquid. Freezing: liquid → solid. Evaporation: liquid → gas. Condensation: gas → liquid.
🧪 Challenge: an ice cube in a glass. How many minutes will it take to melt in the sun? And in the shade? Predict before measuring!
