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.
A couple of years ago I was asked to be a mentor teacher to a new teacher. We sat in on what seemed endless meetings for first year teachers. Frank Forsthoefel told a story about his young daughter. His daughter's teacher called home to talk to her...before the first day of school. He mentioned the positive impact it had on both him and his daughter. A light turned on. What would happen if I called home to everyone of my students BEFORE the first day of school?
In the August 4th issue of Science Magazine, author Mary Soon Lee shared a review of a periodic table that contains haiku for each element. There is an interactive periodic table you can click on; it was easily viewable in the mobile version of the article.
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.
A classroom activity to demonstrate the principles of chemical kinetics and equilibria and the utility of the mole concept is described here. The activity involved no hazardous materials or complex equipment and can be enjoyed and appreciated by general studies students as well as chemistry majors.
In a previous blog post, I shared a book Chemistry: A Very Short Introduction, by Dr. Peter Atkins. For my summer reading I wanted to get back to reading some chemistry non-fiction. I did, however, diverge from my original plan to read Eric Scerri's The Periodic Table: It's story and significance. Instead. "Four Laws That Drive the Universe" (with an alternative title of The Laws of Thermodynamics: A Very Short Introduction) became my next book as I so thoroughly enjoyed the writing style of Peter Atkins. The Kindle Version is only $6.15 and worth every penny in my opinion.
Students can build their own Hoffman apparatus. An animation of the electrolysis on a particulate level is available to show students before, during or after students perform the electrolysis.
Megan was watching a show about Nicola Tesla. She was so impressed that afterwards she decided Nicola needed an "emblem". She made one, put it on her Etsy site and the rest is history. The response was great and an idea was born. Nicola was the first of many emblems. Megan said she is not sure if she is a nerd who loves art or an artist who embraced her inner geek. Either way, her stickers, posters, t-shirts, flashcards and designs are super cool.
ChemEd X is preparing for CHEMED 2017! If you are attending the conference, we hope you will stop by our booth in the exhibit hall and introduce yourself.
Erica Jacobsen shares highlights from the July 2017 issue of the Journal of Chemical Education that are of special interest to high school chemistry teachers.
