Attractions between Molecules

Thursday, December 19: We ended 2019 with an introduction to Lesson 42: Attraction Between Molecules.  For our entry task, students watched the Crash Course video below:

After the video, students worked on the Polarity and Intermolecular Forces Gizmo which will be due on Monday, January 6, 2020.

Monday, January 6: We began the year with a new student-selected seating chart.  While students arranged themselves, they received back the Chapter 7 quiz from December 18.  We then reviewed the quiz with students sharing out answers.  Next, we reviewed the concept of polarity and intermolecular forces (class notes shown below).  Finally, students had the remainder of the class period to complete the Gizmo, complete the Lesson 41 molecule poster project, and to read lessons 42 and 43 in the textbook and answer the lesson exercises.
