Topic: Energy technology 

Technology

 Standard 6.  Understands the nature and uses of different forms of technology
  Level I (Grade K-2)
   Benchmark 3.Knows that energy comes from different sources (e.g., electricity, gas, water) and is used in many common objects (e.g., a stove, some toys)
    Knowledge/skill statements
     1.Knows that energy comes from different sources
     2.Knows that energy comes from electricity
     3.Knows that energy comes from gas
     4.Knows that energy comes from water
     5.Knows that many common objects use energy
     6.Knows that stoves use energy
     7.Knows that some toys use energy
  Level II (Grade 3-5)
   Benchmark 3.Knows that different types of energy (e.g., solar, fossil fuels) have different advantages and disadvantages (e.g., solar energy is a cleaner source of energy than fossil fuels, but currently is more expensive), and that regardless of the source of energy, the technological design should attempt to maximize the use of it
    Knowledge/skill statements
     1.Knows that different types of energy have different advantages and disadvantages
     2.Knows solar energy is a cleaner source of energy than fossil fuels, but currently is more expensive
     3.Understands that regardless of the source of energy, the technological design should attempt to maximize the use of it
  Level III (Grade 6-8)
   Benchmark 3.Knows that most technological systems require an input of energy, which is an important consideration both in designing an object or a system and in conserving energy (e.g., so many things require energy that alternative sources to fossil fuels should be used when possible)
    Knowledge/skill statements
     1.Knows that most technological systems require an input of energy
     2.Knows that energy requirements must be is an important considered when designing an object or a system
     3.Understands that because so many things require energy, alternative sources to fossil fuels should be used when possible
  Level IV (Grade 9-12)
   Benchmark 3.Understands scientific principles of energy, work, and power in relation to technological design (e.g., the Second Law of Thermodynamics means that a system cannot be designed which is 100% efficient)
    Knowledge/skill statements
     1.Understands scientific principles of energy in relation to technological design
     2.Understands scientific principles of work in relation to technological design
     3.Understands scientific principles of power in relation to technological design
     4.Understands that the Second Law of Thermodynamics means that a system cannot be designed which is 100% efficient
   Benchmark 4.Knows that power systems (i.e., systems which convert energy from one form to another) have a source of energy, a process, loads, and some have a feedback system
    Knowledge/skill statements
     1.Knows that power systems are systems which convert energy from one form to another
     2.Knows that power systems have a source of energy
     3.Knows that power systems have a process
     4.Knows that power systems have a load
