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.
Erica Jacobsen shares highlights from the October 2019 issue of the Journal of Chemical Education of special interest to our ChemEd X community.
I met some amazing teachers at Chem Ed 2019. Two of these teachers are Yvonne Clifford and Sharon Geyer who ran a workshop about chemical demonstrations. One in particular caught my attention. The demonstration was an exothermic process with paraffin wax. Here is the demonstration.
My top 5 reasons for using Green Chemistry in my classroom along with a few examples of replacement labs that follow Green Chemistry principles.
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.
The ACS Committee on Chemical Safety has released the 8th edition of "Safety in Academic Chemistry Laboratories". The publication provides advice for first- and second-year university students.
