Invitation to engage
Dear Fellow Educators, I want to start by thanking you for your commitment to opening young minds to the wonders of science. Your mentorship may well be responsible for the big inventions of the next generation. To inspire your students even more, I’d like to help you introduce them to some of the exciting new science currently being constructed at the Chemistry Department, University of Toronto.

Growing a chemistree and a competition -cover article
When I first encountered a chemistree as a new teacher, I thought it was brilliant and naively, a new idea. I soon learned that this idea had been around forever — like so many other ideas. Last year Twitter helped me discover more chemistrees through an online competition

Ramah Bay 7,000 years of Aboriginal culture — and chemistry
With this issue of Chem 13 News, we have the first in a series of articles on chemistry in northern Canada, focussing specifically on the Inuit context. The unique Inuit life and culture has developed experimentally over thousands of years in response to the challenges of limited material and food resources. And now life is being impacted by new material additions to daily lives (including pollutants).

Sharing chemistry with the community: Battle of the blues
Every year during basketball season, two institutions, the University of North Carolina (UNC) and Duke University, battle on the court to see which team (and university) can claim the title of being the best. As they are only eight miles apart and have two of the best coaches in all of college basketball, one can only imagine the intensity of the rivalry between the two schools.

Sharing chemistry with the community: Limiting and excess reagents
The determination of the limiting and excess reagents in a chemical reaction tends to be a challenge for many chemistry students. Teachers have used the making of cookies and hamburgers, or combinations of nuts and bolts, among other common items to help students understand these concepts. While students understand that if you have 10 hamburger patties and only 6 pickles one can only make 3 hamburgers, if each requires 2 pickles.

Vitamin C, chemically known as L-ascorbic acid, is an important nutrient that provides support to body structures, contributes to wound healing and aids the immune system in preventing infection. In this activity, participants learn how to determine whether vitamin C is present in commercial drinks and, if so, how to measure the relative amount.

Everyone enjoys playing with soap bubbles. We have turned this enjoyment into a series of activities that not only gives people the opportunity to once again experience this enjoyment but to also learn about soap bubbles. We have taken the Bubble-ology presentation to places like North Carolina’s Museum of Life & Science in Durham and the Marbles Kids Museum in Raleigh.

Sharing Chemistry with the Community: ‘Elephant’s toothpaste’
On its own, hydrogen peroxide slowly decomposes into oxygen and water. For this reason, fresh bottles of drugstore hydrogen peroxide, labeled 3%, are actually 6%. This is so the hydrogen peroxide remains above 3% at the expiration date, if stored properly.

Sharing chemistry with the community: Follow up
I submitted a manuscript about the “Exploding Gummy Bear” that was published in the February 2014 issue of Chem 13 News. The editor, Jean Hein, her staff and I wrestled with the safety issues and the underlying chemistry associated with this demonstration. It was even suggested not to publish the article because of these concerns.

Sharing chemistry with the community
One of the many advantages of having students peruse sources of chemical demonstrations rather than my telling them which ones they should perform is that they occasionally come across demonstrations that I have not seen before. One example of this is when Stacey Wolfson found “How to Blow Out a Light Bulb” in A Demo A Day, Volume 2, B. Bilash II, G. Gross, & J. Koob, (1998), pages 208-209, Flinn Scientific, Inc. This demonstration was new to me.

NO FeAr Science Club
I realized after I had left the ChemEd 2013 Conference last year that my school, Jacob Hespeler Secondary School in Cambridge, was missing out by not having a Science Club. So this past school year I started one. The first thing I needed was a name — and the name ultimately chosen was inspired by a former student who loved chemistry so much that she got a tattoo (not recommended until after you have passed first year "killer" chem).

Sharing chemistry with the community: “Molding a thermoplastic”
When thermoplastic polymer became available a couple of years ago, we purchased a bottle to see if it would be a viable addition to our chemistry outreach program. Since then, literally hundreds of people, young and old, have experienced molding the thermoplastic, taking their creations home in Zip-loc® bags.

Molding a thermoplastic
Elaine “Lainey” Williams learned the procedure for the thermoplastic shaping activity, tried out various combinations of the dyes, instructed her classmates and shared this activity with 4th to 6th grade girls who recently participated in the FEMMES (Females Engaged in More Math, Engineering, and Science) Capstone event. The following are Lainey’s thoughts about learning the procedure, the underlying chemical concepts and sharing the thermoplastic activity with others.

Sharing chemistry with the community: A colorful catalyst
The catalytic oxidation of tartrate ions by hydrogen peroxide has been a staple of the Duke chemistry instructional program for many years. The demonstration clearly and colorfully brings to life the textbook description of what a catalyst is and how it enables a reaction to proceed at a faster rate by becoming involved in the reaction, yet in the end returns to its original state.

Carving a can with chemistry
Aluminum cans are used for juices, soda and beer. The cans receive, on the inside, a plastic film that prevents the contact of the liquid with the metal. On the outside, the cans are painted with the brand's logo and other information. This external paint protects the aluminum surface from corrosion.

Polyurethane foam smoothies continue to be one our most popular hands-on, make-and-take activities. They are easy to do, safe to perform (with supervision), inexpensive, and useful for illustrating several chemical concepts for a wide range of audiences. Another plus, each participant can take his or her smoothie home and talk about the process of making it and the underlying chemistry with family and friends.

“The chemistry of US currency – Magnetic ink” Sharing chemistry with the community
Demonstrating the magnetic ink used in printing US currency has proven to engage audiences of all ages because of its relevance to everyday life. Nearly everyone has used machines that distribute and/or accept currency but few understand how the machines distinguish between the various denominations. The key is in the face of each denomination.

Sharing chemistry with the community: “Walking on Oobleck”
Oobleck, a mixture of cornstarch and water, derives its name from the story “Bartholomew and the Oobleck” by Dr. Seuss (Random House), in which the king, tired of the rain, snow, and sleet falling from the sky, wishes for something different. Soon his wish is granted; green, sticky, gooey oobleck falls making a mess of his kingdom, leading the king to regret his wish. Bartholomew saves the day by getting the king to say the magic words, “I’m sorry.”
