Wave Properties
Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave. 

Wave Reflection, Absorption, and Transmission
Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.

Digitized Wave Signals
Integrate qualitative scientific and technical information to support the claim that digitized signals are a more reliable way to encode and transmit information than analog signals.
