2 short discussion question due tonight at 9pm Sunday May 5th 2019
SCI 110: Intro to Physical Science
Week 5 Discussion
Top of Form
"Chapters 10 and 11"
Discussion Option 1:
Our topics this week relate to WAVES. We see (and hear!) waves everywhere. Sound is a wave that travels through the air, and musical notes are produced when the sound wave has particular properties.
For this discussion option watch the short video below of sound waves being shown by a device called an "oscilloscope" ("oscillare" means to swing or oscillate, "scope" means to see) and then answer the questions below it:
Oscilloscope and Frequency

Questions:
1. Describe what happens to the shape on the screen when the tone being played gets louder or softer. How does this relate to what we learned about waves? (Use the appropriate terms from the following list: frequency, amplitude, wave length, period)
2. Describe what happens the shape on the screen when the tone being played note gets lower (deeper) or higher in pitch. How does this relate to what we learned about waves? (Use the appropriate terms from the following list: frequency, amplitude, wave length, period)
Please respond to two students posts in the discussion. Make your responses detailed and personalized. The goal is to have an interesting discussion and interaction with our classmates!
Discussion Option 2:
Refer to the section marked “Discussion Questions (Evaluation)” at the back of each of the assigned chapters (Chapters 10 & 11).
1. For each chapter, pick one of the discussion questions to address. Copy the question into the forum, along with your answer (see examples in Weeks 2 and 3). We are looking for a post for each chapter.
2. Reply to at least two fellow students with a follow-up question, comment, or a different perspective on their discussion questions.
