Activity: Future of Paint Video Questions

In this activity, students will watch a video and answer related questions about the fascinating and innovative scientific advancements of paint. During the video, Students will learn how the molecular components in paint are helping to evolve in the world around them.
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.
Melting Point, Intermolecular Forces, Polarity, Boiling Point, Molecular Geometry | High School

Activity: Examining the Strength of Intermolecular Forces of Attraction

In this activity, students will be able to understand the strength of the attractions of the three intermolecular forces (IMFs) and use this information to help identify physical properties of molecules (such as melting point, boiling point or states of matter).
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.

Lesson Plan: An Exploration of Intermolecular Forces

In this lesson students will explore intermolecular forces, and their associated effect on physical and chemical properties. Students will experiment with volatile liquids to investigate their predictions about intermolecular strength.
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.
Electricity, Polymers, Molecular Structure, Heat, Temperature, Molecular Geometry, Electronegativity | High School, Middle School

Video: The Future of Paint Video

This video explores the fascinating and innovative scientific advancements of paint. Students will learn how the molecular components in paint are helping to evolve in the world around them. Futuristic paint is capable of replacing light switches, conducting electricity, and regulating temperature amongst other things!

Lesson Plan: The Downside to Catalysts - An Exploration of CFC's on the Ozone Layer

In this lesson students will make observations of a colorful homogenous catalyst and intermediate in a reaction demonstration that will spark their interests. They will then work in teams to analyze graphs and data sets in order to make a real-world connection to AP topics in kinetics such as catalysts, intermediates and reaction mechanisms by exploring how CFCs work to break down the ozone layer. Students will also investigate and discuss this environmental issue.
Intermolecular Forces, Polarity, Molecular Geometry | 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.
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.
Mixtures, Solubility, Intermolecular Forces, Polarity, Solute & Solvent, Intermolecular Forces, Molecular Geometry | High School, Middle School, Elementary 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**

Activity: Simulation Activity: Ionic and Covalent Bonding

In this simulation, students investigate both ionic and covalent bonding. Students will have the opportunity to interact with many possible combinations of atoms and will be tasked with determining the type of bond and the number of atom needed to form each. The simulation visually differentiates between the transferring of electrons when forming an ionic compound and the sharing of electrons when forming a covalent compound so that students can have a complete understanding of each. Finally, students will become familiar with the molecular formula, as well as the naming system for each type of bond and geometric shape, when applicable.
