Because of the altered class schedule yesterday and the short class period today, we skipped Lesson 52 and moved ahead to Lesson 53.  We will return to Lesson 52, which involves a lab where students make rudimentary thermometers, when we return from the 4-day holiday break on Wednesday (2/17).  Today, class began with a short SciShow video about the Kelvin Scale:

After the video, students worked through the Lesson 53 Worksheet.  The Lesson 53 PowerPoint is available for review by clicking here.  For homework, students should complete textbook questions 6, 9, 11, and 12 or take notes on the lesson.
