Waves
 
Focus Question: What is the best way to insulate a recording studio from outside sound?
 
Students will reflect on how different materials affect sound waves (absorb or reflect) and think about sound made in an empty space. They will also reflect on their own engineering process and compare to how they previously laid out the steps. Students will explore the oscilloscope on Fossweb.com to further reinforce their understanding of the relationships between amplitude, frequency and volume. They will go over all their notes to prepare for the investigation 2 test.

Waves
 
Focus Question: What is the relationship between wave properties and wave energy? and How are engineering challenges solved?
 
Students will determine the relationships between wave amplitude, frequency, wavelength and energy. In addition, they will consider the Tacoma Narrows Bridge case study. After learning about the bridge failure, they will consider the steps required to solve an engineering problem. They will learn more about the decisions made in the Tacoma Narrows design.

WEEK 28: 3/30- 4/4           *SCHOOL CLOSURE plans 
Waves
 
Focus Question: What defines a wave? and What is the relationship between wave properties and wave energy? 
 
This week, you will finish Investigation 1 by understanding the parts of a wave. You will continue onto Investigation 2 to learn about mechanical waves, which travel through medium. You will watch a video about ocean waves as an introduction to wave energy. After defining energy, you will determine the relationships between wave amplitude, frequency, wavelength, and energy.
