  • Polarity, Periodic Table, Molecular Structure, VSEPR Theory, Electronegativity | 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, Polarity, Molecular Structure | Elementary School, Middle School, High 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.

  • Mixtures, Solubility, Intermolecular Forces, Polarity, Solute & Solvent, Intermolecular Forces, 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**

  • Polarity, Molecular Formula, Covalent Bonding, Ionic Bonding | 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**

  • Intermolecular Forces, Polarity, Covalent Bonding, Ionic Bonding, Electronegativity, Metallic Bonding | High School

    Activity: James Bonded

    In this activity, students create a video of collisions that represent chemical reactions.

  • Intermolecular Forces, Polarity, Physical Change, Intermolecular Forces | High School

    Activity: Intermolecular Forces Activity

    In this activity, students will represent molecules and energy to investigate the different types of intermolecular forces.

  • Intermolecular Forces, Polarity, Physical Change, Molecular Motion, Molecular Motion, Intermolecular Forces | High School

    Activity: Simulation Activity: Comparing Attractive Forces

    In this activity, students will use a simulation to investigate different types of intermolecular forces (London dispersion and dipole-dipole). In the analysis that follows the activity, they will relate IMFs (including hydrogen bonding) to physical properties (boiling point and solubility).

  • Intermolecular Forces, Polarity, Molar Mass, Intermolecular Forces, Boiling Point, Heat of Vaporization | High School

    Lab: Heat of Vaporization

    In this lab, students test whether a substance’s heat of vaporization is determined by its molar mass, the strength of its intermolecular forces, or both.

  • Observations, Physical Properties, Mixtures, Solubility, Intermolecular Forces, Polarity, Identifying an Unknown, Intermolecular Forces, Chemical Properties, Intramolecular Forces, Mixtures | High School

    Lab: Solubility & Compound Type

    In this lesson, students determine whether unknown substances are polar, nonpolar, or ionic by testing their solubilities.

  • Density, Physical Properties, Mixtures, Solubility, Freezing Point, Polarity, Phase Changes, Intermolecular Forces, Colligative Properties, Intermolecular Forces, Freezing Point Depression, Mixtures | High School

    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).

  • Observations, Separating Mixtures, Physical Properties, Intermolecular Forces, Polarity, Distillation, Cracking, Balancing Equations, Intermolecular Forces, Boiling Point | High School

    Lesson Plan: Fractional Distillation of Crude Oil

    In this lesson, students will be introduced to simple distillation while expanding their knowledge of intermolecular forces. Once a simple distillation has been accomplished in the lab, students will then research the various products of fractional distillation of crude oil and report on one of those products.

  • Observations, Physical Properties, Mixtures, Intermolecular Forces, Polarity, Intermolecular Forces, Mixtures | Elementary School, Middle School, High School

    Lab: Salad Dressing Science: Emulsions

    In this lab, students mix polar and nonpolar substances and then add various emulsifiers to encourage the mixing of the two substances. They use ingredients in salad dressing to relate science to real life scenarios.

  • Polarity, Covalent Bonding, VSEPR Theory, Molecular Geometry, Electronegativity | High School

    Lesson Plan: Polarity

    In this lesson, students learn some tips about how to determine whether a molecule is polar or nonpolar by question features about Lewis structures and symmetry.

  • Physical Properties, Mixtures, Solubility, Melting Point, Intermolecular Forces, Freezing Point, Polarity, Molecular Structure, Solute & Solvent, Intermolecular Forces, Boiling Point, Intramolecular Forces, Graphing, Mixtures, Lewis Structures | High School

    Lab: Physical Properties (High School)

    In this lesson, students investigate how intermolecular forces effect physical properties by investigating substances’ melting points as well as solubility.

  • Physical Change, Intermolecular Forces, Polarity, Physical Change, Molecular Motion, Molecular Motion, Intermolecular Forces | High School

    Simulation: Comparing Attractive Forces

    In the November 2014 issue, students explore the different attractive foreces between pairs of molecules by dragging the "star" image. In the accompanying activity, students investigate different types of intermolecular forces (London dispersion and dipole-dipole). In the analysis that follows the investigation, they relate IMFs (including hydrogen bonding) to physical properties (boiling point and solubility).
