Hello kids! Today we're going to learn about water and its amazing ability to change forms. Water can be three different things: ice when it's very cold and hard, liquid water that flows like what we drink, and invisible water vapor that floats in the air. Let's explore how water transforms!
Let's see what happens when water gets cold! When the temperature drops, water starts to freeze. The water molecules slow down and stick together, forming ice crystals. Ice is solid and hard, unlike liquid water that flows. This process is called freezing!
Now let's see what happens when ice gets warm! When we heat ice, like putting it in the sun or a warm room, it starts to melt. The ice crystals break apart and become liquid water again. This process is called melting! The water can now flow and move around freely.
Now let's see what happens when water gets really hot! When we heat water a lot, like boiling it in a pot, something amazing happens. The water turns into water vapor - an invisible gas that floats up into the air! This is called evaporation. You can't see water vapor, but it's all around us!
Amazing! Water is like a magical shape-shifter that changes based on temperature. When it's cold, water becomes solid ice. When we add heat, ice melts into liquid water. Add more heat, and water evaporates into invisible vapor. Cool the vapor down, and it becomes water again! This endless cycle happens all around us in nature. Remember: temperature is the key that controls water's amazing transformations!
