Objectives:

The student is expected to:

• identify and describe the changes in position, direction of motion, and speed of an object when acted upon by force (*6.5-A),
  
• identify forces (such as movement of water) that shape features of Earth (*6.6-C),
  
• describe how systems may reach an equilibrium (*7.5-A),
  
• illustrate examples of potential and kinetic energy (*7.8-A),
  
• demonstrate how unbalanced forces cause changes in the speed or direction of an object's motion (*8.7-A),
  
• recognize that waves are generated and can travel through different media (*8.7-B),
  
• illustrate interactions between matter and energy including specific heat (*8.10-A),
  
• describe interactions among solar, weather, and ocean systems (*8.10-B)
