The Water Cycle in a Baggie with Interactive Notebook Ideas

Want to see a fun idea for teaching the water cycle?  

  The whole water cycle can be seen in a model using water and a ziplock baggie.   Seal the baggie and tape to a window to warm.   As the process unfolds, students can identify accumulation, condensation, precipitation and evaporation.  I like to have the students set up the experiment and then formulate their ideas and definition based on their experiences.   Teacher will probably need to guide them with some skillful questioning.

Teacher Background Information:

    Water on earth is used over and over. The water cycle is the continuous movement of water from ocean to air and land then back to the ocean in a cyclic pattern, is a central concept in meteorology. In the water cycle, the sun heats the Earth's surface water, causing that surface water to evaporate (gas). This water vapor then rises into the earth's atmosphere where it cools and condenses into liquid droplets. These droplets combine and grow until they become too heavy and fall to the earth as precipitation (rain, snow, sleet, hail).
    Water accumulates and is temporarily stored in lakes, glaciers, underground, or living organisms. The water can move from these places by streams and rivers, returns to the oceans, is used by plants or animals or is evaporated directly back into the atmosphere.


Some additional crafts for the water cycle.
