New publication platform

Issues from 2012-now are online. In 2018 we will be transitioning from print/online to just online. There are 600 articles from 50 issues on our Publication Platform site. Subscribe to our e-mailing list to hear about new issues and articles.  

Below are links to older material not found on the Publication Platform. This list was posted before the Publication Platform was launched in 2018 so it is older supplemental material. 

You can always contact us at Chem 13 News (chem13news@uwaterloo.ca) if you are looking for something and we are happy to help!

We have a great mole pattern -- an oldie but a goodie.  It is from 1997  from National Mole Day Foundation.  Email Chem 13 News (chem13news@uwaterloo.ca) and we will email you the 3-page PDF with complete instructions.  The great thing about this mole is that it can be cut in half -- 0.5 moles! 

Thanks Melissa Jones, Austin, Texas for finding this in her files and sending it to us. It was her paisley stuffed mole, pictured below, that caught our attention at ChemEd 2017.  Thanks also to NMDF for giving us permission to post it.

In this issue, we had another article on Gummy Bear demo, which included important safety considerations.  The April issue 2010 of Chem 13 News also featured some Gummy Bear Safety.  We caution you to read all the safety considerations if you are considering this demo. CLEAPSS in the UK also have a "Howling /Screaming Jelly Baby"  risk assessment for you to consider. (CLEAPSS is an advisory service providing support in science and technology in the UK.)

Mirror ornament photos on the back cover of this issue mirror ornaments for your chemis-treeof Chem 13 News ​were sent in by Andrea Hawkins, Queen of Angel Academy, Dorval QC.  Andrea's students used the Lab: Chemis-tree ornament from the front cover of the December 2000 issue.  

We also have a similar lab with a few extra hints if you are interested. If you email us, we will send you a copy of the lab sent in by Ed Escudero, Summit Country Day School, Cincinnati OH.  Ed's lab had some extra advice, i.e., importance of having the surface to be mirrored extremely clean.

If you do this lab or make any ornaments with your class, email us.  We are planning to make a collection of ornaments for next year. 

Take a look at Psuedo-individualized assignment for VSEPR theory by David Cash's article in December 2000.

Also watch Yehoshua Sivan's simple "steam engine" in action. Learn how to make this in the holiday issue.   

May 2013 -- puzzles

Every issue of Chem 13 News has had at least one original puzzle with great prizes donated by Educational Innovations. Try your hand and two of our favorites.

One is our ever popular crostic by Gerry Toogood.  This puzzle is aimed at the exceptional students and chemistry teachers who love words.  Try to solve our May 2013 puzzle -- A light-hearted crostic

The other puzzle is designed for chemistry students. Have your students try our Mole Maze puzzle from the May 2013 issue. Our goal is to make these puzzles something a teacher can use for a fun assignment, for an extra challenge for a supply teacher, or a bonus after a lab or test.
