Unit 4: Characteristics of Waves

STANDARD: S8P4   Obtain, evaluate, and communicate information to support the claim that electromagnetic (light) waves behave differently than mechanical (sound) waves.

ELEMENT: S8P4.d   Develop and use a model to compare and contrast how light and sound waves are reflected, refracted, absorbed, diffracted or transmitted through various materials.

LEARNING TARGETS: (Clarification statement: Includes echo and how color is seen, but does not cover interference and scattering)

1. I can define reflected, refracted, absorbed, diffracted and transmitted. (Knowledge)
2. I can explain the difference between light and sound waves. (Knowledge)
3. I can describe the reflection, refraction, absorption, and diffraction of light and sound waves. (Reasoning)
4. I can explain how light and sound travel through various materials. (Reasoning)
5. I can illustrate and describe what happens when a sound echoes.  (Reasoning)
6. I can illustrate and explain how color is seen. (Reasoning)
7. I can develop and use a model to compare and contrast how light and sound waves interact with matter. (Product)
