“Phases of W ater” Brain pop. Draw a picture of H20 molecules in a gas, liquid, and solid (in that order) Act it out!. Water Molecules. Water is made up of molecules . Water changes state (gas, liquid, solid) when it’s molecules are heated or cooled. Molecules.
Water is made up of molecules . Water changes state (gas, liquid, solid) when it’s molecules are heated or cooled.
Water molecules become less dense when heat is added. This happens when water changes from ice to liquid or from liquid to gas.
Water molecules become dense when in cold temperatures. This is seen when water turns to ice or changes from a gas to liquid.
Turn and Talk.
Draw what you think the molecules look like at each stage of the water cycle.
Every day, trillions of liters of water evaporate from the ocean
Transpiration is the release of water vapor into the air from a plant’s leaves
Condensation is the change of state from water vapor to liquid.
Precipitation is any type of water that reaches the Earth (rain, snow, sleet, hail)
When water reaches the ground, three things happen to it:
1. Water runs down hills over surface (runoff) and collects in oceans, rivers, lakes, streams (accumulation)
2. Water seeps into the ground
3. Water evaporates back into the air
