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.
In this blog post, I would like to share a relatively simple demonstration you may use to introduce the concept of antioxidant along with its potential in everyday life.
Looking to change up your titration lab? Citric acid is very common in candy and other foods. Students will be engaged in using titration to find the amount of the acid in Mentos Now or other candy. Student and teacher documents are provided to help you use the activity with your own students.
One 50 minute class period if the instructor prepares the standardized NaOH.
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.
Placing Chemistry into a World Context
The April 2018 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: service-learning, safety, investigating student understanding of solutions, environmental chemistry, green chemistry, waste management, acid-base chemistry, natural products, materials science, activities and laboratory investigations, teaching resources, diving into the archives: marine chemistry.
As a secondary science teacher, I have contact with my students everyday. Making relationships and learning about all of my students is key to letting them know that I am invested in their success.
