August 2019 Xchange

The August 2019 Xchange highlights some of the contributions that have been published on ChemEd X over the past month. We hope you will take a moment to check in and see what you may have missed. 

As you prepare for the 2019 - 2020 school year, we hope you will share this newsletter with a colleague that might not be familar with our community. We also encourage you to expand your network by engaging in discussion with authors and other members of our community by logging into your ChemEd X account and commenting on posts that interest you. 

Best wishes for an inspiring school year!

Intrinsic Motivation for the Chemistry Teacher – Time to Collaborate!

Motivation is important in the field of education. With the Next Generation of Science Standards (NGSS) taking hold in most states across the country, it is arguably more important than ever for teachers to understand what motivates them. The author calls chemistry teachers to collaborate and challenges them to find what intrinsically motivates them as a chemistry teacher.

     

Career Profile: Chemist & Technical Staff for Sandia National Laboratories

Read Dr. Sam Eaton's career profile describing his background and his current position within Sandia National Laboratories. The article is part of the Faces of Chemistry - Career Profiles project intended to help teachers and their students understand the wide variety of career paths available in the field of chemistry.

     

Stop Motion Animation - Galvanic Cell Process

With few materials available to complete wet labs in her school, the author found a creative way to make sure her students were getting the idea of the macroscopic changes that take place in a galvanic cell without necessarily being able to do the wet lab. 

A General Method to Prepare Halogen-Free Oxalate Diesters for Peroxyoxalate Chemiluminescence Demonstrations

Chemiluminescence demonstrations that use peroxyoxalate “glowstick” systems are very popular in a variety of lecture demonstrations and classroom activities. This article presents a simplified modification of the published procedures for the preparation of multigram quantities of oxalate diesters derived from vanillin and methyl salicylate.

Revisiting the Rainbow Safety Alert

Having another accident related to the rainbow demonstration in the news recently the American Chemical Society's Committee on Chemical Safety has reached out once again asking that the larger community share the warning about using the Rainbow Demonstration. They want to spread the word about the dangers of the Rainbow Flame Demonstration so no further injuries occur. 

     
     

Inquiry and Direct Instruction in the Age of NGSS

When it comes to the best approach for student learning, there seems to be two very divided camps: those who promote direct instruction and those who favor inquiry. As many teachers are changing their curriculum to teach Next Generation Science Standards, it is important to reflect and consider how this transition is going.
