  1. Boyle’s ActivityCombined Gas Law

  2. Objective: • Today I will be able to: • Explain how pressure, temperature and volume effect the movement of gas particles in Boyle’s Law. • Correctly solve Combined gas law problems • Evaluation/Assessment: • Informal assessment – monitoring group interactions and questions as they complete the activity, practice problems and exit ticket • Formal assessment – analyze student responses as they complete the practice and exit ticket • Common Core Connection • Make sense of problems and persevere in solving them • Reason abstractly and quantitatively

  3. Lesson Sequence • Evaluate: Warm – Up • Engage and Explore: Boyles Law Activity • Elaborate: Boyles Law Activity Discussion • Elaborate: Gas Law Flip Book • Explain: Combined Gas Law • Elaborate: Combined Gas Law Practice • Evaluate: Exit Ticket

  4. Warm - Up • According to Boyle’s law when temperature is constant, as volume increases, pressure ______. • According to Charles’ law when pressure is constant, as volume decreases, temperature ______. • According to G-L’s law when volume is constant, as temperature increases, pressure ______.

  5. Objectives • Today I will be able to: • Explain how pressure, temperature and volume effect the movement of gas particles in Boyle’s Law. • Correctly solve Combined gas law problems

  6. Homework • Pressure Conversions, Boyles, Charles, G-L Law Quiz • B-day April 10 • A-day April 11 • Finish WS

  7. Agenda • Warm – Up • Boyles Law Activity • Boyles Law Activity Discussion • Gas Law Flip Book • Combined Gas Law • Combined Gas Law Practice • Exit Ticket

  8. Boyles Law Activity Analyze the relationship between pressure and volume

  9. Activity Directions (15 minutes) • Watch Ms. Ose’s demo • Be sure to rotate the books 90 degrees when stacking • Have one person stack, one person spot and a 3rd person record the data and read the measurement • Measure from a consistent line, each time

  10. Boyle’s Law Activity Discussion • What would you predict the graph of your data to look like? • Why did you record 3 trials of data? • If a normal sea-level recipe is used to prepare a cake at a location 1000 meters below the surface of Earth, the cake will be much flatter than expected. Explain why, and offer a solution.

  11. Gas Laws Flip Book Staple the flip book together. Fill your information into the flipbook for Boyle, Charles and Gay- Lussac’s Law. Record the values for STP on the front.

  12. Combined Gas Law Notes

  13. Combined Gas Law • Put Boyle’s, Charles, and Gay-Lussac’s Laws together • Used when a variable is not held constant • P1V1 = P2V2 T1 T2

  14. Combined Gas Law/Mixed Gas Law Practice Complete the practice at your desk. Whatever is not completed in class will be completed for homework.

  15. Exit Ticket • You purchase a balloon from the store on a cold day. You take it outside and notice that the balloon deflates. When you take it back inside your house, the balloon inflates again. Explain what is happening based on the gas laws.
