Engaging Unit 5 Review through Amazing Race Activity

On April 12, 2013, students will review Unit 5 concepts through an engaging Amazing Race activity. The session will begin with warm-up questions focusing on pressure and temperature relationships. The agenda includes investigating the Lake Nyos disaster and completing analysis questions based on readings. Students will participate in collaborative review activities, solve practice problems involving the Ideal Gas Law, and prepare for the upcoming test. Emphasis will be on applying theory to practical scenarios, culminating in a thorough understanding of gas laws.

  1. Warm-UpApril 12, 2013 • Write down the date and objective. • Objective: SWBAT review Unit 5 by competing in Amazing Race. • Complete the following warm-up questions: • 1. Label each graph as either pressure vs. temp, pressure vs. volume, or pressure vs. # of particles:

  2. Objective & Agenda • Objective: SWBAT review Unit 5 by competing in Amazing Race. Agenda • Lake Nyos • Gut check • Amazing Race • Review • Exit Slip • College FRIDAY!!

  3. Ideal Gas Law Lab Calculations

  4. Practice Problems- Part 2

  5. Lake Nyos Disaster • Read the article and answer questions 1-4 on a separate sheet of paper. • Write in complete sentences

  6. Analysis • Charlotte is located between two lakes, Lake Norman and Lake Wylie. Should people in North Carolina be concerned about a disaster like this happening? Write one paragraph that defends whether or not we should be concerned about this. Give evidence based on the information in the article.

  7. Tuesday’s test • Will cover: • Conceptual Pressure Problems • Pressure Conversions • Partial Pressure • Ideal Gas Law • Combined Gas Law • P/V • V/T • All three variables

  8. Gut Check • My basketball is too pumped up. Name 3 ways I can lower the pressure (one each for V, n, and T). • Increase Volume, Decrease n, Decrease T • If I have 2 moles of gas held at a pressure of 4 atm and a temperature of 100 K, what is the volume of the gas? • 4.01 L • A gas takes up a volume of 5 liters, has a pressure of 2 atm, and a temperature of 100 K. If I raise the temperature to 200 K and lower the pressure to 1 atm, what is the new volume of the gas? • 20L • Convert 147 psi to mmHg. • 7,600 mmHg

  9. Amazing Race • Answer the question and show all work on your answer sheet (note the numbering) • One partner runs up and checks answer with me. If correctgrab the next question. If incorrectfix it. • First 3 groups to finish get Extra Credit on the exam Tuesday. • Once you finish you need to work on the Unit 5 Review which is due Monday

  10. Exit SlipApril 12, 2013 • A container holds the gases O2, CO2, and N2. If the total gas pressure of this container is 67 atm, and both O2 and N2 have a pressure of 12 atm, what is the pressure of CO2? • After casting a spell on a chemistry experiment, Harry Potter has a container with a pressure of 3040 torr, volume of 57 L, and temperature of 86oC. If the container started with a volume of 49 L and pressure of 5.5 atm, what was the initial temperature?

  11. COLLEGE FRIDAY!!
