Objectives:

The student is expected to:

• know that some change occurs in cycles (*5.6-A).
  
• identify and observe actions, such as flow, that require time for changes to be measurable (*5.11-A).
  
• identify forces, such as movement of water, that shape the features of Earth (*6.6-C).
  
• demonstrate that changes in motion can be measured and graphically represented (*6.6-B).
  
• know that an equilibrium of a system may change (*7.5).
  
• relate the role of oceans to climatic changes (*8.12-B).
  

* Refers to the Texas Essential Knowledge & Skills for science.
