Electronegativity and Polarity

Entry Task

After completing the entry task, we reviewed the results of the Graphing Practice entry tasks from the week before Winter Break.  Next, we transitioned to Lesson 43 by first watching the Crash Course chemistry video about polar and non-polar molecules:

Following along with the polar bear theme, students received copies of the Lesson 43 Worksheet and accompanying cartoon.  After reading through the cartoon and working through the worksheet, we briefly worked through parts of the Lesson 43 PowerPoint and students received a copy of the periodic table that includes the electronegativity values for each element.
