Gingerbread mini bath bombs
Angela Swartz from the Waterloo-Oxford District Secondary School in New Hamburg, ON sent in this cover photo of festive holiday bath bombs she made in the shape of mini gingerbread cookies.
Our Science Department enjoys planning themed activities that correspond to different holidays. Last year we decided to make bath bombs with our classes on the last day of school before the winter holiday. This is an activity that is easy to set up, can be carried out in one class period, and has minimal clean up. Author: Angela Swartz, Waterloo-Oxford District Secondary School, Baden, Ontario
A tribute to Carey Bissonnette
This November issue is dedicated to Carey Bissonnette, who sadly passed away in May of this year. Many of you will remember him as the Chem 13 News Exam and Avogadro Exam coordinator as well as for his series "Tough Questions." We have included a heartfelt tribute by Bill Power, Chair of Waterloo's Department of Chemistry, a reprint of Carey's Tough Questions series, as well as tributes from readers.
The Mendeleev Mosaic
Students, teachers, and chemistry enthusiasts from 15 countries around the world submitted 327 original portraits of Mendeleev, which were then used to create a larger mosaic portrait of Dmitri Mendeleev himself.
Indicator puddle art
Isobel Everest, Bedford Girls' School, Bedford, UK - also known as @crocodilechemist on Twitter - sent in this cover photo of art created with droplets of colourful indicators. Read more about how she did it, plus see more of her artwork in this month's cover art feature.
The inspiration for making pictures from droplets of chemicals first came from a Chemistry Club session at our school. Author: Isobel Everest, Bedford Girls' School, Bedford, United Kingdom
Many years ago I attended an ASM Materials Science Teachers’ Camp in Ottawa that covered polymers, ceramics, metals and composite materials. During one session they discussed how western society had lost the Roman recipe for concrete after the empire collapsed.

Doug Ragan from Hudsonville High School, Michigan captured the beauty of red fluorescing chlorophyll extracted from spinach in a 100-mL beaker.
Another great cover from the chemistry classroom? It is not what you think! Thank you Vivian Templeton who teaches at Toronto District Christian High School, Woodbridge, Ontario for sending this in!

The beautiful eye image on the front cover is a microscale experiment, which is a combined effort of Andres Tretiakov, Kensington Park School and Bob Worley at CLEAPSS in the United Kingdom. This “puddle chemistry”, an affectionate term for microscale reactions in drops, takes place on a liquid crystal temperature sensor.
The cover slime-stretching photo captures the result of students making their own products in our organic chemistry unit.
Pablo Picasso was a Spanish painter, known for his influential paintings, his ingenious use of cubism and for inventing the technique of constructed sculpture. He was an exceptional artist of his time and painted not what was admired by the world, but what he saw. He was an abstract painter, just as chemistry is a very abstract topic that comes in many shapes and explanations.
May 2018 cover
How great is it for students to get to experience working in the lab, all while creating a useful piece of lab equipment that can be used for the remainder of the school year? Within the first month of school, my 10th grade chemistry students perform a series of lab experiences. They practice techniques such as heating a test tube, reading a thermometer to the proper number of digits and — always a student favorite — making their own glass stir rod.
Glowing flowers
Using the camera on her phone, Chloe Hoang, a student at Hilliard Bradley High School, Hilliard Ohio captured these glowing flowers under black light. Teachers Courtney Goodwin and Jennifer Kieffer organize monthly Chemistry Club meeting.
I have been fortunate to have attended two ASM Material Camps for educators. I knew after having attended the first day of Part 1 that I would be starting my new school year with a copious amount of relevant material. The material was presented in such a manner that I could easily go back to my classes and add to my repertoire.

The Fluorescent Chemis-tree on the front cover was created by Brian Wagner, a professor of chemistry, at the University of Prince Edward Island, Charlottetown, PEI.
I co-instruct and coordinate an undergraduate materials and nanoscience (MNS) lab at the University of Waterloo. One experiment in 2nd year consistently stands out as my students’ favourite, and it involves the synthesis and characterization of “capped” cadmium selenide (CdSe) “quantum dots” (QDs).
This is a favourite of the students

A meaningful science-based activity on the last day of school before winter holidays is important.
This photo shows the combustion of magnesium inside a block of dry ice, a demo performed at the University of Waterloo Science Open House Chemistry Show as part of National Chemistry Week. Although dry ice is very cold (-78 °C) and CO2 is used in some fire extinguishers, Mg (once ignited) will undergo a redox reaction with CO2 to produce MgO and carbon. This dazzling reaction produces a very bright glow and lights up a darkened room. Photo taken by Martin Schwalbe.
Sarah Langlois captured the spectacular reaction between potassium and water in a series of photos. The photo on the left shows the characteristic purple flame of this reaction.
Jack Glaser, a student in Jenn Wagner’s class at Scarsdale High School, Scarsdale, New York submitted this amazing photo of an aqueous solution freezing.
