As a printable pdf: green chemistry for St. Patrick's Day
We have a great mole pattern -- an oldie but a goodie. It is from 1997 from National Mole Day Foundation. Email Jean Hein, email@example.com 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.
The photo of the front cover of the September issue was sent in by Andres Tretiakov, Science Technician at St Paul’s School in London UK. The photo captured lighting one of his home-made matches. The videos below shows the matches in action.

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 of 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.

May 2013 -- puzzles
Every issue of Chem 13 News has two original puzzles.
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. The student puzzles have great prizes donated by Educational Innovations.
If you have a puzzle or a challenge for chemistry students or teachers, send them to Jean Hein, editor of Chem 13 News.
