Erica Jacobsen shares highlights from the June 2018 issue of the Journal of Chemical Education.
The June 2018 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: investigating nanoscopic structures, innovative curriculum, inquiry-based investigations, using games to teach, outreach on climate change and research ethics, instrumental analysis, organic chemistry laboratory experiments, scientific data analysis, chemical education research, from the archives: food dyes.
How do you demonstrate how a buffer system works? I did some brainstorming, devised a plan and it went well. This post is a description of what I did.
This activity is designed to determine the concentration of Vitamin C (ascorbic acid) in a produce protector (in this case, Ball® Fruit Fresh) by an iodometric titration method.
Simple methods to prepare liquid air are described. In addition, ways to test the properties of liquid air and other liquefied gases are explored.
Recently, while attending the High School Teacher Day at the ACS National meeting in New Orleans, we were given Wack-A-Pack™ valentine balloons and encouraged to play with them. I am a huge fan of finding chemistry in the real world and using it as an integral part of my instruction; and as we were experimenting, I was reminded of a rather fun activity I had done on Valentine’s Day with my AP students.
Titrating this year for me has an added complication. The complication is that half of the science department has to be completely packed up and out of our rooms, including chemicals and equipment, before school ends. Half of the department is going to be completely remodeled (my half of course). Teaching must still go on in the middle of the madness.
I was drawn to an article by Eilks, Gulacar, and Sandoval about Acid-Base Chemistry and Chemical Equilibrium in the April 2018 issue of JCE. The title of the article is "Exploring the Mysterious Substances, X and Y: Challenging Students' Thinking on Acid-Base Chemistry and Chemical Equilibrium." The premise of the article is to demonstrate how an instructor may use a group of compounds (zeolites) to "elaborate on the behavior of solid state acids and bases" while revisiting LeChatelier's principle.
Radioactivity is a topic in chemistry that can be difficult to teach if you are looking for a hands-on, data-driven approach. Safety and cost concerns often prevent students from having an inquiry-based experience with the topic. In this post, I will share how I am able to give my students an authentic lab experience for them to determine there are three types of ionizing radiation without direct instruction.
