This school year my district is launching a 1:1 Chromebook initiative. 6th and 9th graders will receive their Chromebooks next semester as part of the rollout. In the meantime, I continue to have access to my Chromebook cart from the Blending Learning pilot I participated in last school year. My goal is to incorporate even more tech use when appropriate; so far, I have increased Chromebook use in my classroom for things like warm up questions, EdPuzzles, and quizzes. My experience with quizzes has been especially interesting.

Topics featured in this issue include: cost-effective instrumentation, including 3D printed instruments and low-cost spectroscopy; laboratory instrumentation and equipment; effective teaching assistants in chemistry; laboratory experiments; resources for teaching; puzzles and games to introduce the periodic table.
In the June 6th, 2016 Chemical and Engineering News magazine put out by the American Chemical Society, C&EN talks with Deborah Blum, journalist and author: From the article’s description, ‘The Poisoner’s Handbook’ writer talks about the beauty of chemistry and why she wants people to know more about it.
Visualizations for Chemistry Teaching and Learning
The June 2016 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: visualizations for chemistry teaching and learning, periodic table resources for teaching visually impaired students, biochemistry in the classroom and laboratory, spectroscopy in the laboratory, commentaries on analytical chemistry topics, resources for teaching, distilling the archives: guided-inquiry experiments.
During our review since last week, resonance was labeled as one of the most tricky concepts (along with electron pushing in my opinion), despite lots of practice and instruction. My teaching sequence consists of defining and providing examples of conjugation (after learning about hybridization), delocalized electrons, and finally pushing electrons if conjugation exists. I remember from teaching at the college level that resonance was also a tricky topic for many undergraduates.
While attending a professional development session last year I was introduced to the Talk Science Primer, developed by the Inquiry Project and TERC. Although the research and sample population targeted educators and students grades three through five, I decided to review the material to analyze if it had any value in a chemistry classroom.
As we pilot new laboratory activities in the classroom, my students and I are in constant dialogue. Not only do they leave feedback at the end of each lesson (what did you learn, what was your favorite part, what was you least favorite part), but we talk throughout the experiment. Recently our discussion was focused on the questions.
This year in the midwest United States, winter has been a fickle friend. I haven’t seen the same amount of snow or ice as in recent years, but I still made sure I was prepared for it at our home. I went to my local big box hardware store in December and contemplated buying rock salt (NaCl), and NaCl/calcium chloride mixture, or just calcium chloride. Growing up my dad had switched entirely to calcium chloride because it was less damaging to the brick pavers leading to our porch and backyard. In fact, calcium chloride is generally much safer toward plants and soil than NaCl. Even though calcium chloride is much more expensive than rock salt (it was about twice the cost for 10 pounds more), that what’s I chose. Why?
