Updated: Now includes print and digital options for the lesson. Perfect for distance learning or the paperless classroom. Interactive student notes, exit ticket, and homework for Google Slides™ with Google Apps.

Your students will master intermolecular forces and molecular polarity with this straight forward lesson. At this point, students should be able to draw Lewis structures and identify the molecular geometry of molecules. In this lesson, students will determine molecular polarity and determine the intermolecular forces that exist between molecules. Again, students must have mastered drawing Lewis structures prior to this lesson, as they will draw Lewis structures of each molecule in order to determine its polarity.

I do consider this an honors level lesson, but you will have to evaluate its use depending on the level of your students, and your curricular requirements.

The included teacher notes are packed full of information for the teacher. They include a full lesson plan with objectives, NGSS alignment, a suggested demonstration, an awesome homework activity, and slide-by-slide background information. The recommended demonstration included in the lesson is relevant and one that I always tell students to definitely try at home!

Lesson Objectives:
Differentiate between intramolecular and intermolecular forces
Define dipole, and determine the direction of a dipole moment in a polar molecule
Explain what determines molecular polarity
Determine molecular polarity for a sample of nonpolar and polar molecules
Describe how electronegativity differences determine the distribution of charge in a polar molecule
Describe dipole-dipole forces, London dispersion forces, and hydrogen bonding and their effect on properties such as boiling point.
Identify intermolecular forces between molecules as dipole-dipole, London dispersion forces, or hydrogen bonding.


Prior Knowledge:
An understanding of electronegativity and electronegativity differences, covalent bonding, Lewis Structures, and molecular geometry

Note on the PowerPoints: The PowerPoints included in this product are editable. They are also animated, which means that they may appear busy or overlapping in the slide edit mode, but will be awesome in the slide show mode! Please don’t edit the PowerPoints until you have seen them in the slide show mode!

This lesson is appropriate for grades 9-12 chemistry

This will be a lesson you will want to use year after year!
