3.7 - Earth and Space Systems: Water Cycle

The student will investigate and understand that there is a water cycle and water is important to life on Earth. Key ideas include

a)  there are many reservoirs of water on Earth;

  • identify the different ways that organisms get water from the environment Bloom's Level: Knowledge / Understand
  • compare and contrast major waterways including rivers, lakes, ponds, oceans, groundwater, and wells.  Bloom's Level:  Analyze
  • identify  and locate major water sources in the local community Bloom's Level: Knowledge

b)  the energy from the sun drives the water cycle; and 

  • identify the origin of energy that drives the water cycle Bloom's Level: Knowledge

c)  the water cycle involves specific processes;

  • describe the processes of evaporation, condensation, and precipitation as they relate to the water cycle Bloom's Level: Understand / Apply
  • construct and interpret a model of the water cycle.   Bloom's Level: Create / Analyze

BIG IDEAS

Water is an essential to Earth processes.  The water cycle is a model that illustrates how water is conserved within environments.


UNDERSTANDING THE STANDARD

  • The water cycle is a chain of events that continuously repeats.
  • The cycling of water ensures its availability for life processes.
  • Water is essential for life on Earth.
  • The water cycle is important because its process provides Earth with the natural, continual water supply all living things need in order to survive.
  • The water cycle is the continuous movement of water on, in, and above Earth.  
  • As with all cycles, it does not have a specific beginning or end point. While water does circulate from one point or state to another in the water cycle, the paths it take are variable.
  • The energy that drives the water cycle comes from the sun.
  • During the water cycle, liquid water is heated and changed to a gas (water vapor) by a process called evaporation.
  • The gas (water vapor) is cooled and changed back to a liquid by a process known as condensation or it can form ice crystals (solid).
  • Water as a liquid or a solid falls to the ground through a process called precipitation.

ESSENTIALS

Essential Questions:

·  What are the main water sources on Earth?

·  How does the sun's energy influence water on Earth?

·  How can you describe the water cycle?


In order to meet this standard, it is   expected that students willt.

  • compare and contrast major waterways.
  • identify the sun as the origin of energy that drives the water cycle.
  • describe the processes of evaporation, condensation, and precipitation as they relate to the water cycle.
  • construct and interpret a model of the water cycle.
  • identify the different ways that organisms get water from the environment.
  • identify major water sources for a community, including rivers, reservoirs, and wells. Describe the major water sources for the local community.
  • identify and locate major water sources in the local community.
