This lesson aligns with the Common Core State Standards:
STANDARD 5 - Matter and Energy
"The competent science teacher understands the nature and properties of energy in its various forms, and the processes by which energy is exchanged and/or transformed.
5A. understands the atomic and nuclear structure of matter and the relationship to chemical and physical properties
5C. understands the cause and effect of chemical reactions in natural and manufactured systems

5F. explains conservation of mass and energy and explains interactions of energy with matter, including changes in state"
Student note guide to the PowerPoint lesson II in the "Chemical Bonds" unit V - introductory chemistry. This lesson explains how atoms are held together in covalent bonds; compares polar and non-polar bonding with unequal electron sharing; and describes molecular attractions with polar and nonpolar molecules.
PowerPoint lessons contain many graphics and links to short videos to further student understanding.
PowerPoint slides also contain notes for the instructor based on students most "frequently asked questions" or FAQ's to help clarify the subject.
A class activity is included at the end of each lesson.
*All PowerPoint lessons; review programs; student worksheets/activities and assessments for this unit can be found under the "Introductory Chemistry Complete Unit V Chemical Bonds" zip file folder.
Terms/concepts covered in this lesson include:
