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.
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.
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.
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 Flinn website sums up their software with these sentences, "Flinn’s Online Chemventory™ Inventory Management System(link is external) is a cloud-based lab management system that allows multiple users on multiple devices from multiple locations! Available as a 1-Year, 3-Year or 5-Year license.
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.
As we all know, research and general educational practice clearly indicates that students learn science best by doing it – not just reading about it. Hands-on, process and inquiry based science is the key to understanding science. Unfortunately, this is a double edged sword for science teachers in that doing science has its potential hazards and resulting risks. Science laboratories, classrooms and field work sites can be unsafe places to teach and learn. If a student gets hurt while doing an activity in the lab, in the field or even at home if it was a teacher’s assignment, there is potential shared liability for both the teacher and the school.
I decided to take the time and to do some needed inventory. I wanted to match equipment to its designated table. Next, I wanted to make sure that each of my eight lab tables had the proper equipment needed to eliminate no more missing equipment. Sure enough, as I began the inventory project, I had several tables missing equipment, so once everything was laid out and counted and organized then I had to make sure it was going to stay that way. I had several rolls of colored tape and it was easy to then begin marking each of the pieces of equipment and glassware with tape.
The ACS Committee on Chemical Safety has published new Guidelines for Chemical Laboratory Safety in Secondary Schools. This document is organized with the R.A.M.P. concept – Recognize the hazard, Assess the risk of the hazard, Minimize the risk of the hazard, and Prepare for emergencies. The online document includes two pages for each letter that could be printed and posted in the classroom to reinforce these principles of safety. The documents are provided to strengthen the safety practices of teachers and help them to promote a culture of safety that their students will take with them throughout their academic and professional careers.
