Narrative Summary:

The STC Sound kit has been revised to bring it more into alignment with the Rhode Island Grade Span Expectations for science.  Since light and sound are both forms of energy, it makes sense to combine them into one unit which describes that energy is needed for change to occur in matter and energy can be transferred or transformed (both RI statements of enduring knowledge).

In addition, light and energy share many similar properties in that:

• Both can be described as waves

• Both have frequencies

• Both can be reflected, bent or absorbed

• Humans can hear only a portion of possible sound ranges and see only a portion of the light spectrum

• Our eyes and ears can be damaged by overexposure to strong sounds or UV light
