AACT Simulations


To take advantage of its digital delivery platform, many issues of Chemistry Solutions feature a simulation and an accompanying lesson.
  • Simulation

    Exciting Electrons

    In this simulation, students will explore what happens when electrons within a generic atom are excited from their ground state. This is a qualitative investigation, not meant to mimic any particular atom.

  • Simulation

    Heating Curve of Water

    In this simulation, students will investigate qualitatively and quantitatively what happens as water changes states.

  • Simulation

    Molecular Motion

    In this simulation, students will have the opportunity to explore on the molecular level how particles move in three states of matter. They will compare two different substances.

  • Simulation

    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.

  • Simulation

    Periodic Trends I: Ionization Energy, Atomic Radius & Ionic Radius

    In this simulation, students will investigate several periodic trends, including atomic radius, ionization energy and ionic radius. Through the use of this simulation students will have the opportunity to examine atomic data as well as visually compare and interact with select elements from the periodic table.

  • Simulation

    Periodic Trends II: Electron Affinity, Atomic Radius, & Ionic Radius

    In this 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.

  • Activity

    Gas Laws

    In this activity, students will examine gas laws by carrying out several computer simulations.

  • Lab

    Density Lab

    In this lab, students determine the density of several liquids and solids. They then identify an unknown metal by determining its density. They then calculate the percent error within the class for a specific sample.

  • Simulation

    Building an Atom

    In this simulation, students manipulate the number of protons, neutrons, and electrons in an element and determine how these effect the mass number, atomic number, and other properties of an atom.
