Weather: Molecular View of Pressure

We began class with the Meters, Liters, and Grams video:

After the video, we briefly reviewed the Metric System:

We worked through a few practice problems from Appendix A in the textbook (page A-0) which integrate the metric system and dimensional analysis.  After the

We then transitioned to Lesson 60, providing students the opportunity to make connections between Charles’s Law, Boyle’s Law, and Gay-Lussac’s Law.  Although we did not review it in class, the Lesson 60 PowerPoint is available for students to review.  The Lesson 60 Worksheet called for students to use a University of Colorado PhET simulation.  Because our Chromebooks are unable to run Java, students instead observed a teacher-led demonstration of the simulation software.  For homework, students were assigned textbook problems 3-9 (odds).  Students with access to a Windows-based computer are encouraged to try the simulation (embedded below):

Weather: Charles’s Law

We formally connected observations about the relationship between temperature and volume by introducing Charles’s Law.  The Lesson 54 PowerPoint includes the definition of Charles’s Law and introduces k, the proportionality constant.  We worked through the ChemCatalyst and watched a few minutes of a YouTube video showing a lava lamp in action:

We sketched out a before/during/after model of how a lava lamp works and the white board notes are shown below.  Students then practiced working through Charles’s Law by completing the Lesson 54 Worksheet.  For homework, students were assigned textbook questions 1 and 7 (or Notes).
