Wave Behaviors
...
Subject Area: Science | Grade Level: 8
Lesson Length: 2 hours
Keywords/Tags: Reflection, Refraction, Absorption, Transmission
Lesson Description: Students will investigate the effects different mediums have on waves and how waves interact with each medium.

  • Other S8P4. Obtain, evaluate, and communicate information to support the claim thatrnelectromagnetic (light) waves behave differently than mechanical (sound) waves. rn. Develop and use a model to compare and contrast how light and sound waves are reflected,rnrefracted, absorbed, diffracted or transmitted through various materials.rn(Clarification statement: Include echo and how color is seen but do not cover interferencernand scattering.)

Standards

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

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. (Clarification statement: Include echo and how color is seen but do not cover interference and scattering.)


Leaing Objectives

I can identify when light is being refracted, reflected, absorbed, or transmitted when looking at real-world scenarios
I can predict what a wave will behave like when it encounters different objects
