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.
Undergraduates Need a Safety Education is the title found in the commentary section of the September 2016 Journal of Chemical Education. It is written by Robert H. Hill Jr and it explains the lack of safety education in chemistry curriculum. As I read this, I thought back to my safety education that prepared me for my role as a high school chemistry teacher and felt I was very fortunate to have had an undergradutae class that was specifically designed to teach chemical safety.
One of my favorite things to talk about with my colleagues is the use of lecture demonstrations in teaching. There seems to be a push in my district to stop using chemicals whenever possible and get to computer simulations and video in place of wet chemistry. I don’t think they are thrilled with me since I can’t envision ever taking the chemistry out of chemistry.
