Classroom Commentary | September 2018 Reflections of an AP Chemistry Exam Reader
This article describes a chemistry teacher’s experience as a Reader for the AP chemistry exam. She shares some reflections, pointers, and insights to help guide other AP Chemistry teachers in hopes of helping them prepare their students to achieve mastery on the exam.
Simulation | September 2018 States of Matter and Phase Changes
In this simulation, students will participate in a 10 question quiz. Some questions will challenge students to analyze data to identify the correct state of matter for a specific sample, and then connect the chosen state with an animated particle diagram. In addition, students will examine the behavior of particles in an animated sample as they undergo a phase change, and must correctly identify the change that occurs.
Resource Feature | September 2018 Chemistry of Lightsticks: Determination of Activation Energy, a Guided Inquiry Approach
Lightsticks, with their eerie glow, capture the interest of students of every age. Capitalizing on this, the authors describe how they developed and used a guided inquiry approach to help students determine the activation energy of the chemiluminescent reaction in a lightstick. They also describe how they used a Vernier LabQuest 2 system, while acknowledging that any data collection system that allows simultaneous collection of data from light and temperature probes may be used instead. In addtion, they explain how they employed the natural logarithm form of the Arrhenius equation and spreadsheet software.

Nuts & Bolts | May 2018 Using Learning Progressions to Improve Scientific Modeling in Chemistry
This article describes how to use learning progressions to transform your existing modeling activities to help students construct and use models as a generative tool for predicting and explaining phenomena. In the process, the models become a learning tool, rather than just a means to illustrate understanding.
Tech Tips | May 2018 Use Moodle to Score Lab Calculations Instantly
One of the greatest time demands for chemistry teachers is the assessment of lab work. With a little bit of preparation, you can program Moodle (a widely available and free learning management system used by many schools) to correct students’ lab calculations and provide immediate feedback. The author walks through an example using a simple stoichiometry exercise used with his 11th grade general chemistry students.
Resource Feature | May 2018 Embracing Chemistry in the Elementary Classroom
This article discusses why it's important for K-5 teachers to overcome the fear of teaching chemistry, and gives some simple suggestions on how to start.
Simulation | May 2018 Reaction Rates
In the May 2018 simulation, students investigate several factors that can affect the initial rate of a chemical reaction, including concentration, temperature, surface area of the reactants, and addition of a catalyst.
Classroom Commentary | May 2018 The AP Chem Exam is Over - Now What?
This article discusses a short course in computational chemistry, designed for AP Chemistry teachers and students, primarily to be used for chemistry enrichment following the completion of the AP Chemistry exam.
Nuts & Bolts | May 2018 Strategies for Teaching SPED and EL Students in the Chemistry Classroom
The article explores several different strategies for teaching EL and SPED students in the high school chemistry classroom.
Editorial | May 2018 Refresh and Refocus through Reflection
Jenelle Ball reflects on both her school year and her time as the AACT Governing Board President. She highlights some newly-implemented and improved member benefits as well as some particular resources that she valued this year. She hopes all teachers will take time as the school year comes to an end to also reflect on their lessons learned and refocus for the future.
Nuts & Bolts | March 2018 21st Century Skills in High School Chemistry
This article discusses the changing trends in science education, with a focus on the need for implementing 21st century skills into the science curriculum, and some techniques for doing so.
Editorial | March 2018 The Importance of Outreach
AACT President-Elect Sherri Rukes shares thoughts about her experience doing outreach in the chemistry teaching community. She is an enthusiastic promoter of chemistry across all grade levels, and encourages others to follow a similar path.
Resource Feature | March 2018 Teaching Beyond the Cookbook
Inquiry lab experiences provide students with a wider context for understanding the material presented in the classroom while improving student engagement and giving them a more authentic science experience. If you want to include more aspects of inquiry in your laboratory experiences, but lack the time and money to test brand new labs, this article provides specific tools and ideas for adding inquiry experiences to your own labs.
Simulation | March 2018 Chemical Reactions and Stoichiometry
In this simulation, students practice classifying different chemical reactions, balancing equations, and solving stoichiometry problems.

Simulation | November 2017 Predicting Shifts in Equilibrium: Q vs K
In this simulation, students will take a 15 question quiz. Each quiz question has two parts. The first part requires the student to calculate the value of the reaction quotient, Q. In the second portion of the question, the students will compare the value of Q to the equilibrium constant, K, and predict which way the reaction will shift to reach equilibrium. The simulation includes five different reactions which each have three scenarios: Q > K, Q = K, and Q < K.
