  Lesson Plan: The Downside to Catalysts - An Exploration of CFC's on the Ozone Layer Mark as Favorite (37 Favorites)

  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.

• 

  Lesson Plan: Intermolecular Forces Review Mark as Favorite (24 Favorites)

  In this lesson plan, students will review concepts of intermolecular forces.

• 

  Lesson Plan: AP Chemistry Big Idea Review Mark as Favorite (126 Favorites)

  In this lesson, students will complete a review of all of the AP Chemistry Big Ideas and Learning Objectives using questions targeting each learning objective. This lesson is based on the AACT AP Chemistry Webinar series: What’s the Big Idea? Last Minute AP Chem Review and What’s the Big Idea? AP Chemistry Review Redux.

  Lesson Plan: An Exploration of Intermolecular Forces Mark as Favorite (57 Favorites)

  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.

• 

  Activity: Simulation Activity: Comparing Attractive Forces Mark as Favorite (119 Favorites)

  In this activity, students will use a simulation to investigate different types of intermolecular forces (London dispersion, induced dipole, and hydrogen bonding). In the analysis that follows the activity, they will relate IMFs (also including dipole-dipole) to physical properties (boiling point, solubility, and vapor pressure). This activity and simulation are appropriate for students in any level chemistry course.

• 

  Activity: VSEPR Modeling Mark as Favorite (76 Favorites)

  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.

• 

  Activity: VSEPR with Balloons Mark as Favorite (62 Favorites)

  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.

• 

  Lab: Aspirin Tablets: Are they all the Same? Mark as Favorite (55 Favorites)

  In this lab, students will design an experiment to test the time and completeness of dissolution of various types of aspirin in different pH environments.

• 

  Activity: Ionic Bonding Brackets Mark as Favorite (62 Favorites)

  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.

• 

  Activity: Properties of Common Molecular Substances Mark as Favorite (60 Favorites)

  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.

• 

  Simulation: Comparing Attractive Forces Mark as Favorite (49 Favorites)

  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).
