Diffusion of HCl(g) from concentrated solutions of HCl can be used to illustrate some chemistry related to the train accident in Ohio.
Tom Kuntzleman conducts a safer "mercury-like" beating heart experiment with an added splash of gratefulness.
The classic classroom or lab activity using coin flips to illustrate the first order kinetics of radioactive decay is connected to the tragedy of radiation exposure of workers at facilities using radium-containing luminescent paint. Some of the chemistry related to the contamination of these “radium girls” is explored, with connections being made to the Principles of Green Chemistry and the United Nations Sustainable Development Goals.
Service animals will continue to become more common in chemical laboratories. It is important that chemistry faculty and departments are prepared to safely accomodate students with service dogs in laboratory courses.
Liquid nitrogen is used to visualize the aerosol particles emitted while speaking, coughing, breathing, and sneezing. The ability of various masks to block these droplets was also tested.
Erica Jacobsen shares highlights from the October 2019 issue of the Journal of Chemical Education of special interest to our ChemEd X community.
Zena McFadden presented a story titled "Too Many Lab Rules" during The Mole Storytelling Jam held as part of BCCE 2018. Listen to her podcast.
It’s the beginning of a brand new school year, and a brand new opportunity to capture students’ interest in chemistry and the joy of lab-based sciences! In thousands of chemistry classrooms across the country, teachers will be planning labs, demos, and ways to have students be engaged and excited about learning.
Is your school district providing OSHA required safety training to teachers and other staff that will be in the science labs in your building?
In this post, I share my thoughts about positive relationships as well as some of the activities that I do on the first day of school to make connections with my students.
