Identifying Energy and Energy Transformations

Solar panels are used to power a house. Construct an argument explaining the energy transformations that occur from sunlight to powering a light bulb inside the house. Be sure to use academic language such as "transform," "convert," "input," and "output" in your explanation. Include evidence or examples to support your claim.

Sentence Stem:

• "In a solar panel system, the input energy is ___ energy, which transforms into ___ energy."

• "This energy is then converted into ___ energy to power a ___ (specific system or object)."

• "Evidence to support this includes ___, which shows how energy moves through the system."

• "In conclusion, the transformations from ___ to ___ make the solar panel system an effective energy source."

• Rubric for Constructed Response:

   Identifying Energy Transformations: ____/5 points

  o Correctly and thoroughly identifies the types of energy involved in the system.

   Use of Academic Language:_____/5 points

  o Effectively uses academic language terms like "transform," "convert," "input,"

  and "output" in context to explain energy transformations.

   Constructing an Argument with Evidence: ____/5 points

  o Constructs a logical, coherent argument and provides clear evidence to support

  the explanation.
