The September 2023 Xchange highlights just some of the contributions that have recently been published on ChemEd X. We hope you will take a moment to check in and see what you may have missed. 

Using Information from the 2023 AP Chemistry Reading to Improve Exam Performance Michael Farabaugh outlines mistakes and misconceptions that were encountered during the 2023 AP Reading and offers suggestions for improving performance on the AP Chemistry exam.
	Keeping Simulations Simple with Javalab Javalab is a resource for free simulations to support student understanding of chemistry concepts. These web based simulations can be used across different platforms and are simple in their use by students. The open ended aspect of the simulations allow for teachers to be creative in how they are used in class.
First Days, Observations and Sleight of Hand Read about a fun way to open up the topic of observations and conclusions.
	Elmer's Glue Isn't Just for Making Slime: Simple Chemical Demonstrations with Elmer's Glue Josh Kenney shares three simple and inexpensive demonstrations using Elmer’s glue that you will want to try out yourself!
The Floating Soap Bubble The floating soap bubble is an impressive experiment that is surprisingly easy to carry out.
	Teaching Introductory Chemistry by Scott Milam Chemistry teachers are talking about this fantastic new resource!
Simulating Ice Core Analysis to Identify Volcanic Eruptions in the Past This simulated ice core lab provides a great opportunity for students to practice the skill of generating a calibration curve, use different units of concentration beyond molarity, and understand how knowledge of chemistry can uncover past events on Earth.
	Chemical Activities Involving Reversible Thermochromic Pigments The color of a thermochromic system depends on its temperature. The colors of leuco dye-based systems can also be influenced by adding acids or bases to the thermochromic reactions. These can be used to create colorful demonstrations of acid-base chemistry.
Colourful Chemistry of Canning – Part 4 Part 4 of Colourful Chemistry of Canning explores how to make gold in an old tin can!
