Sound Lab Project description This is the direction for the lab Problem: What is the speed of sound in the room? What is the speed of sound outside? How do these two values compare? Explain, compare and contrast the difference between the speed of sound in the room versus outside and account for why they’re different in terms of each other and the standard speed of sound at STP. • Using your speed of sound, I want to also see a graph of wavelength versus frequency for the different sound waves generated by the tuning forks. Wavelengths should be theoretical calculations. [I. Introduction (20 points)] Theoretical background required for the lab (this is where required equations go). Talk about theoretical expectations. [II. Experimental Methods or Procedures (25 points)] Record and discuss EXACTLY what you did. What you used, how you performed the lab, how you recorded data, etc. Include a diagram, title it and label it! If you are calculating something in results; you should use the equation mentioned in the introduction and then show the solution for solving for the desired variable(s). If there are multiple calculations; show work once. If possible, try to not substitute values in when showing work, try to keep the solution in variables. If you do substitute values, don't forget to show units. [III. Results (35 points)] Organize your data into data tables and/or graphs. Discuss observations and experimental results. [IV. Conclusion (20 points)] Discuss theoretical expectations versus experimental results. Don’t forget to reference specific data. Account for error.

International Politics Current Event Memo Spring 2015 Professor Jenn Larson Hard copy due to your TA at the beginning of Week 11's recitation section. AT MOST 2 PAGES, double spaced, plus the printed article STAPLED to your writeup. You are encouraged to discuss potential answers with fellow classmates. How- ever, the writeup must be entirely your own. Find an article from a reputable news organization printed since February 1, 2014 that covers a story relevant to one of the three subjects in international political economy we have covered: International Trade, International Financial Relations, or International Monetary Relations. Print out the article and staple it to your answers to the following questions: 1. Which topic is your article most relevant to: International Trade, International Financial Relations, or International Monetary Relations? 2. Brie y summarize the article. 3. Who are the main actors covered by the article and what are their relevant interests? 4. What institutions are relevant to your article? 5. Lectures have pointed out many controversies in IPE{ some groups favor free trade, some do not; some see the IMF as a helpful institution, some see it as a hurtful institution; some prefer a world currency, some prefer country-specic currencies; and so on. How can the information in your article be used to take a side in one of the controversies raised in class? 1
