    Resource Feature | November 2015 Q & A with Michael Dayah

    Ptable.com is one of the first online periodic tables—and one of the most popular. Created years ago when Michael was a high school chemistry student, his ongoing upgrades aim to support teachers of chemistry.

  • Chemistry close read
    Resource Feature | September 2015 The Chemistry Close Read

    High school chemistry teacher Jenelle Ball joins forces with an English teacher and a librarian to successfully implement an English class reading technique in a chemistry class.

  • Sim density
    Simulation | September 2015 Density

    The simulation for the September 2015 issue allows students to investigate the effect of changing variables on both the volume and the density of a solid, a liquid, and a gas sample. Students will analyze the different states of matter at the particle level as well as quantitatively.

    Classroom Commentary | May 2015 A Dialog on Terminology: Double Replacement vs Ion Swap

    Are ionic AX + BY reactions better titled double replacement or ion swap? Read the discourse between two advanced high school chemistry students, with an introduction and conclusion from their teacher.

  • Sim heating curve of water
    Simulation | May 2015 Heating Curve of Water

    In the May 2015 issue, students explore the heating curve for water from a qualitative and quantitative perspective. Students compare illustrations of each physical state depicted on the curve and calculate the energy required to transition from one state to another.

    Resource Feature | March 2015 Teaching Students the Relevance of Chemistry

    Chemistry has had a tremendous impact on history and continues to impact our lives. Learn about activities that emphasize the relevance and importance of chemistry, and enhance students' excitement for learning the subject.

  • Sim exciting electrons
    Simulation | March 2015 Exciting Electrons

    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.

  • Bubbles cover
    Resource Feature | November 2014 Magic Bubble

    Read about a lesson designed by a teacher that introduces students to particle diagrams via the process of dissolving.

  • Sim comparing attractive forces
    Simulation | November 2014 Comparing Attractive Forces

    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).

  • Chem matters cover
    Tech Tips | September 2014 ChemMatters: A Wealth of Information

    This article describes ChemMatters and highlights several ways to incorporate the magazine into a high school chemistry curriculum. It also features the Teacher's Guide that accompanies the award-winning magazine by ACS.

  • Sim balancing chemical reactions
    Simulation | September 2014 Balancing Chemical Equations

    The simulation for the September 2014 issue comes from PhET and helps students practice balancing chemical equations. AACT helped fund the conversion of this popular simulation into a format that is compatible with all devices, including iPads. PhET provides teacher’s guides for many of their simulations, and teacher-generated activities that can accompany the simulations.
