  Intermolecular Forces, Molecular Geometry, Polarity | High School

  Lesson Plan: The Great Race: A Study of van der Waals Forces

  In this lesson students will investigate intermolecular attractive forces, van der Waals forces. They will construct models of specified molecules and use the models to identify the van der Waals forces that exist between molecules of each substance (London dispersion forces, dipole-dipole forces and hydrogen bonds). Then, using manometers, teams will perform a series of races to determine which substance has the stronger van der Waals forces.

• 

  Periodic Table, Electronegativity, VSEPR Theory, Polarity, Molecular Structure | High School

  Activity: Making Connections between Electronegativity, Molecular Shape, and Polarity

  In this activity, students will find the electronegativity values of a variety of elements, draw the Lewis structures of select molecules that are made with those elements, and identify the molecular shape of each molecule. Students will then be asked to determine if the molecules are polar or nonpolar based on the electronegativity values of the atoms and the molecular shape. Students will use Ptable.com to find information about atoms and molecules and connect what they find to observable properties.

  Physical Properties, Molecular Structure, Polarity | High School, Elementary School, Middle School

  Activity: What Makes Water So Special?

  In this activity, students will become familiar with the special properties of water by completing several activities that investigate the following physical properties/phenomena: cohesion, adhesion, surface tension, and capillary action.

• 

  Solubility, Solute & Solvent, Mixtures, Intermolecular Forces, Intermolecular Forces, Polarity, Molecular Geometry | Elementary School, Middle School, High School

  Animation: Solubility Animation

  In an animation, students will have an opportunity to visualize on the particulate level how solubility works. Examples of ionic compounds and a polar covalent compound show how when water is attracted to charged parts, they dissolve, and when they're not attracted to charged parts they stay solid. **This video has no audio**

• 

  Ionic Bonding, Covalent Bonding, Polarity, Molecular Formula | Elementary School, Middle School, High School

  Animation: Bonding Animation

  In this animation, students will visualize how different chemical bonds form. Examples of ionic, covalent, and polar covalent bonds are animated, and then students are given a sample of compounds to predict the bonding types. **This video has no audio**

  Lesson Plan: Fuel Line Antifreeze

  In this lesson students will explore the role of a gasoline additive, fuel line antifreeze (generally methanol or 2‑propanol), in reducing the potential of water to block fuel lines in freezing weather. Students will prepare test tube models of water-contaminated fuel tanks and explore the effect of adding different types of fuel line antifreeze. This lesson can be used to bolster concepts about miscibility, density, intermolecular forces, phase changes (freezing), and colligative properties (freezing point depression).
