Nuts & Bolts | May 2016 Managing Chemical Wastes in the High School Lab
Need a quick reference on chemical disposal? This article provides a solid starting point to determine proper disposal methods for high school lab waste.
Simulation | May 2016 Periodic Trends: Electron Affinity, Atomic Radius & Ionic Radius
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.
Classroom Commentary | March 2016 Reviving The Reason For My Work
Adrian Dingle re-discovers a love of chemistry academia through a prestigious fellowship—and encourages you to reconnect with your own inspiration for teaching.
Simulation | March 2016 Periodic Trends: Ionization Energy, Atomic Radius & Ionic Radius
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.
Simulation | November 2015 Gas Laws
The simulation for the November 2015 issue allows students to investigate three of the fundamental gas laws, including Boyle’s Law, Charles’ Law and Gay-Lussac’s Law. Students will have the opportunity to visually examine the effect of changing the associated variables of pressure, volume, or temperature in each situation. Also, students will analyze the gas samples at the particle level as well as manipulate quantitative data in each scenario. Finally students will interpret trends in the data by examining the graph associated with each of the gas laws.
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.
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.
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.
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.
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.
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.
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).
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.
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.
