Demonstrate energy transformation.

Demonstration should include

• the relationship between the source and the final output
• energy transfer and storage
• energy efficiency
• loss of energy in the transformation process (i.e., put in 100 percent, never get 100 percent out).

Teacher Resource:

• The National Energy Education Development (NEED) Project Links to an external site.

Process/Skill Questions:

• How is energy transferred?
• Why is energy never 100 percent efficient?
