  1. Chapter 5, Section 1 Sounds in Vibrating Strings

  2. Do Now • What do a piano and a guitar have in common? • How do a piano and guitar make different sounds?

  3. February 13, 2012HW: 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: • 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

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

  5. February 14, 2012HW: 5.1 PTG #1-5, pg. 490 Due Wed/Thurs • 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: • List your materials you will need for the lab-484

  6. 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?

  7. Do Now • If you were tuning a guitar, how would you make a higher pitch sound and a lower pitch sound?

  9. Physics Talk • Read pg. 486-487 • Complete 2 column notes in notebook • Be sure to define • Vibrate • Variable • Pitch • Frequency

  10. Essential Questions-pg. 489 • In your notebook answer the • What does it mean? • How do you know? • Why should you care? • Be prepared to discuss in your group
