1 – 11 of 11 Classroom Resources

  • 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.

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

    Activity: Modeling Molecular Polarity

    In this activity, students will use electronegativity values and their knowledge of covalent bonding to model the bonds in a molecule. Using this information they will learn how to determine the overall polarity of a molecule.

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

    Activity: Discovering Molecular Shapes

    In this activity, students will use tactile methods (manipulation of connected strings) and a computer simulation to discover how electron-electron repulsion determines the 3D VSEPR geometric shapes of simple covalent molecules. It will allow them to practice drawing Lewis structures as well as deepen their understanding of the connection between a molecule’s structure and its shape.

  • Intermolecular Forces, Polarity, Naming Compounds, Molecular Formula, Covalent Bonding, Ionic Bonding, Molecular Structure, VSEPR Theory, Molecular Geometry, Resonance, Electronegativity, Metallic Bonding | High School

    Lesson Plan: Chemical Bonding Unit Plan

    The AACT high school classroom resource library has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. We constructed a unit plan using AACT resources that is designed to teach Chemical Bonding to your students.

  • Physical Properties, History, Covalent Bonding, Polymers, Culminating Project, VSEPR Theory, Chemical Properties | High School

    Project: The Evolution of Materials Science in Everyday Products

    In this project, students will be able to understand the progression of development of an everyday product and display their knowledge through a creative video. They will investigate the history and chemical composition of the product through the present day. The students will then suggest an innovation about how the product can be altered in the future to improve society.

  • Polarity, Covalent Bonding, VSEPR Theory, Valence Electrons, Atomic Radius, Electronegativity, Lewis Structures | High School

    Project: Molecular Modeling

    In this project, students will research a molecule selected from the teacher approved list, construct a three-dimensional model of the molecule, and present their research to the class in a 7-10 minute oral presentation.

  • 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.

  • 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.

  • Covalent Bonding, VSEPR Theory, Molecular Geometry, Resonance | High School

    Lab: Shapes of Molecules

    In this lab, students will investigate the VSEPR geometry of covalent compounds. They will draw Lewis structures, use molecular models, and determine the geometry of covalent compounds. There is a lot of repetition so students gain a lot of practice.

  • 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.
