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 (V=kT), extending the concept of the proportionality constant, k, to gases.  The constant is unique to each gas, and serves to connect temperature and volume.  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 1-7.
