Exploring the Relationship Between Pitch, Frequency, and Tension in Vibrating Strings

This chapter focuses on the fundamental concepts of sound produced by vibrating strings, specifically examining how pitch is affected by frequency, tension, and length. Through hands-on investigations, students will observe the effects of string length and tension on the pitch produced, emphasizing the importance of controlling variables in experiments. The learning objectives include developing the ability to describe the relationship among these concepts and drawing evidence-based conclusions. Additionally, students will engage in discussions and note-taking to solidify their understanding of key terms like vibrate, variable, pitch, and frequency.

  1. Chapter 5, Section 1 Sounds in Vibrating Strings

  2. January 3, 2011HW: 5.1 PTG #1-5, pg. 490 Due Wed • Learning Objective: • Describe the relationship between pitch, frequency, tension, and sound. • Write a conclusion that includes IV, DV, evidence, and the big idea. • Success Criteria: • Observe the effect of string length on the pitch of the sound produced • Observe the effect of tension on the pitch of the sound produced • Control the variables of tension and length • Summarize experimental results • New Seats • Do Now: • Read Chapter Challenge pg. 480-481 • Write LO and SC on a new left-side page • WDYS/WDYT pg. 484 • Agenda: • New Seats • Do Now • Investigate

  3. Investigate • Read #1-5 pg. 485-486 • Create data table to record data from experiment

  4. Summary – Record Answers in Notebook • When you increase the mass (add weights) to the string, the tension on the string increases. What happens to the pitch? • When you increase the distance between the cup & the pulley, but keep the mass the same, what happens to the pitch?

  5. January 4, 2010HW: 5.1 PTG #1-5, pg. 490 Due Wed • Learning Objective: • Describe the relationship between pitch, frequency, tension, and sound. • Write a conclusion that includes IV, DV, evidence, and the big idea. • Success Criteria: • Observe the effect of string length on the pitch of the sound produced • Observe the effect of tension on the pitch of the sound produced • Control the variables of tension and length • Summarize experimental results • Do Now: • Look at your conclusion for 6b from yesterday. Does it have: • IV and DV • Evidence/Data • Big Idea • What happened to the pitch as you changed the length of the string? • What happened to the pitch as you changed the mass on the hanger?
