JCE ChemEd Xchange provides a place for sharing information and opinions. Currently, articles, blogs and reading lists from ChemEd X contributors are listed below. We plan to include other items that the community wishes to share through their contributions to ChemEd X.

Titration of an Esterification Reaction to Determine Equilibrium Constant

ChemEd X recently made a Call for Contributions soliciting input regarding the big ideas being put forth by organizations like AP. The first thing that came to mind was a lab I modified that is centered around making connections between topics. Admittedly, this lab is not a "big idea" per se. Rather, it's the big idea that students should be able to make connections between topics we study to solve problems. So in this blog post, I would like to share a lab activity that relies on these connections - between stoichiometry, esterification, equilibrium, kinetics, titrations and uncertainty of calculations. I will also share the resources I have created to support my students through the process of working through these calculations.

Time required: 

Three class periods

Day 1: setup of equilibrium mixture; roughly 30 minutes

Day 2: titration of equilibrium mixture (approximately 1 week after Day 1); roughly 60 minutes

Day 3: calculations; variable time required - typically 30-90 minutes depending on the student group

Google Forms as an Assessment Tool

This school year my district is launching a 1:1 Chromebook initiative. 6th and 9th graders will receive their Chromebooks next semester as part of the rollout. In the meantime, I continue to have access to my Chromebook cart from the Blending Learning pilot I participated in last school year. My goal is to incorporate even more tech use when appropriate; so far, I have increased Chromebook use in my classroom for things like warm up questions, EdPuzzles, and quizzes. My experience with quizzes has been especially interesting.

Especially JCE: September 2016

“You sank my battleship!” Do you remember this line from a classic commercial featuring the board game Battleship? It sat in my family’s game closet when I was a kid, but it’s popping up again recently, with chemistry twists.

JCE 93.09 September 2016 Issue Highlights

Engaging Student Interest and Inquiry

The September 2016 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: copper chemistry; safety; using brewing to teach chemistry; 3D-printed models; learning using games; open-ended approaches to teaching; innovative methods to teach biochemistry; polymer chemistry; organic synthesis labs; teaching physical chemistry; chemistry field trips.

Using IUPAC's Isotopes Matter as a Digital Learning Tool

Isotopes Matter is a digital learning tool, developed by IUPAC Isotopic Periodic Table, designed to explain isotopes as well as their importance. This resource incorporates mass spectroscopy data into each of the key ideas as well as provides multiple examples as to how varying isotopes are commonly used.

Time required: 

Using Isotopes Matter and the class discussion: 55-60 minutes
