• 

  Percent Composition, Identifying an Unknown, Net Ionic Equation, Atomic Mass | High School

  Lab: Analysis of Carbonate Compounds Mark as Favorite (14 Favorites)

  In this lab, students identify three unknown substances by measuring the amount of product (CO2) produced by a reaction with hydrochloric acid.

• 

  Molecular Formula, Atomic Mass | High School

  Activity: Molecule Building Tournament Mark as Favorite (7 Favorites)

  In this activity, students determine molecular formulas given formula masses and a limited number of atoms.

• 

  Chemical Bond, Molecular Structure, Atoms, Elements, Matter, Interdisciplinary, Naming Compounds | Elementary School

  Lesson Plan: Modeling Molecules Mark as Favorite (0 Favorites)

  In this lesson, students explore the structure of matter by designing, building, comparing, and evaluating models of a variety of simple molecules.

• 

  Emission Spectrum, Emission Spectrum | High School

  Lesson Plan: Modeling Energy in Chemistry: Energy and the Electron Mark as Favorite (16 Favorites)

  This activity is designed for students to build a scientific argument about the relationship between energy and spectral lines by exploring how light interacts with atoms. In the process, students will examine proposed models of the hydrogen atom and use collected data to analyze the proposed models. They will then select one of the models and write a scientific argument to support their choice. Students will then review additional data to support and/or refute their selection. Based on their analysis, students will revise their selected model and construct a new argument to support their revisions.  

• 

  Ionic Bonding, Naming Compounds, Precipitate, Ions, Molecular Formula | Middle School

  Activity: Bond with a Classmate Mark as Favorite (5 Favorites)

  In this activity, students are assigned an ion and form bonds with their classmates, recording the formula and name of the compound they created.

• 

  Trends of the Periodic Table, Electron Affinity, Atomic Radius, Ionic Radius

  Simulation: Periodic Trends II: Electron Affinity, Atomic Radius & Ionic Radius Mark as Favorite (0 Favorites)

  The May 2016 simulation is a follow-up to the March 2016 simulation. Students will focus their investigation on the electron affinity of an atom. Through the use of this simulation students will have the opportunity to examine the formation of an anion as well as compare the atomic radius of a neutral atom to the ionic radius of its anion.

• 

  Trends of the Periodic Table, Atomic Radius, Ionic Radius, Ionization Energy, Valence Electrons | Middle School, High School

  Simulation: Periodic Trends: Ionization Energy, Atomic Radius & Ionic Radius Mark as Favorite (0 Favorites)

  In this simulation for the March 2016 issue, students can investigate the periodic trends of atomic radius, ionization energy, and ionic radius. By choosing elements from the periodic table, atoms can be selected for a side by side comparison and analysis. Students can also attempt to ionize an atom by removing its valence electrons. Quantitative data is available for each periodic trend, and can be further examined in a graph.

• 

  Atomic Theory, Law of Conservation of Energy

  Simulation: Exciting Electrons Mark as Favorite (0 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.
