• 

  Emission Spectrum, Electrons, Electrostatic Forces | High School

  Lesson Plan: Introduction to PES Mark as Favorite (53 Favorites)

  In this lesson students will learn how to interpret simple photoelectron spectroscopy spectra by incorporating their knowledge of electron configurations, periodic trends, and Coulomb’s law.

• 

  Titrations, Limiting Reactant, Acid Base Reactions, Indicators, Chemical Change, Equivalence Point, Stoichiometry, Balancing Equations, Chemical Change, Graphing, Error Analysis, Chemical Change, Error Analysis, Measurements, Concentration, Molarity | High School

  Lab: Acid-Base Mole Ratio Mark as Favorite (16 Favorites)

  In this lab, students study several concepts, including acid-base reactions, limiting reactants, and stoichiometry, by observing the contained reaction of acetic acid (diluted vinegar) with sodium hydrogen carbonate (baking soda) in an unconventional, cost effective titration.

• 

  Intermolecular Forces, Intermolecular Forces, Polarity, Molecular Motion, Molecular Motion, Physical Properties | High School

  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.

• 

  Buffers, Solubility, Molecular Structure | High School

  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.

• 

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

  Activity: Ionic Bonding Brackets Mark as Favorite (64 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.

• 

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

  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.

• 

  Balancing Equations, Precipitate, Solubility Rules | High School

  Animation: Net Ionic Equations Animation Mark as Favorite (68 Favorites)

  This animation explores what happens in a precipitate reaction on the particulate level. Students will see why writing a net ionic equation accurately represents what happens in these scenarios. An example of diluting a soluble solid, mixing two aqueous reactants that yield aqueous products, and mixing two aqueous reactants that yield a precipitate are part of this animation. **This video has no audio**

• 

  Atomic Theory, Law of Conservation of Energy, Electrons, Electromagnetic Spectrum | High School

  Simulation: Exciting Electrons Mark as Favorite (64 Favorites)

  In the March 2015 issue, students explore what happens when electrons within a generic atom are excited from their ground state. They will see that when an electron relaxes from an excited state to its ground state, energy is released in the form of electromagnetic radiation.

• 

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

  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).
