1 – 7 of 7 Classroom Resources

  • Physical Properties, Solubility, Melting Point, Naming Compounds, Molecular Formula, Ionic Bonding, Ionic Radius, Ions | High School

    Activity: Ionic Bonding Brackets

    In this lesson, students will demonstrate their knowledge of ionic bond strength and its relationship to the properties of melting point and solubility using a “brackets” activity. After analyzing the ionic charge and radius to predict the strongest and weakest bond between four pairs of ionic substances, they will then determine which will be the least soluble.

  • Covalent Bonding, VSEPR Theory, Molecular Geometry, Lewis Structures | High School

    Activity: VSEPR with Balloons

    In this activity, students will explore Valence Shell Electron Pair Repulsion Theory using balloon models. Since balloons tend to take up as much space as they can when tied together, they can look like models of central atoms in VSEPR theory, making a great metaphor for the model. This activity is an extension of the activity, Shapes of Molecules found on the AACT website.

  • Polarity, Covalent Bonding, VSEPR Theory, Electronegativity, Lewis Structures | High School

    Activity: Properties of Common Molecular Substances

    In this activity, students will apply their knowledge of molecular polarity, shape, and intermolecular forces to explain the differences in properties between different covalent substances.

  • Molecular Structure, Molecular Geometry, Bond Energy | High School

    Activity: Find the Best Bond Angle and Bond Length of Water

    In this activity, students participate in an introductory level computational chemistry investigation. Students will interact with computational software to conduct this activity and will analyze data to determine the best bond angle and bond length of a water molecule.

  • Molecular Structure, VSEPR Theory, Molecular Geometry | High School

    Activity: VSEPR Modeling

    In this activity, students construct physical models of molecular shapes. However, students are not told what the preferred arrangements of electron pair domains are. Instead, they derive the arrangements. Students are given the opportunity to conceptualize what is happening when one electron pair domain acts upon another, and to understand how those interactions result in the molecular geometries predicted by VSEPR theory.

  • 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).

  • 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).
