GRADE 8 SCIENCE
Unit 7: The Electromagnetic Spectrum - 30 Days
Performance Expectations
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.
Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
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.
