We began class with a brief review of the gas pressure experiments from yesterday. Students shared results and ideas, then updated their models and explanations.

Next, having thoroughly explored gas laws involving two variables (Pressure & Volume, Pressure & Temperature, and Temperature and Volume), students were introduced to the Combined Gas Law, k=PV/T. We began class with the video below:

For our work today, students were tasked with reading Lesson 61 in the textbook and then working through the Lesson 61 Worksheet. For additional practice, students should work through the exercises at the end of Lesson 61 in the textbook.
