Each year we work on specific heat of materials and the heat of fusion of ice. These are two labs that are typical for most chemistry classrooms. Most of the experiments involve a simple calorimetry experiment that uses a styrofoam cup and provides generally good results. There tend to be a couple of key ideas with all of these experiments.

Learn a simple and very inexpensive way to build and use an "absorption spectrometer" using a smartphone. This is a great way to implement Beer's Law experiments in your classroom!

Computer coding has been getting a lot of attention with the Hour of Code movement and President Obama’s recent “Computer Science for All” initiative. Just like it is no longer solely the job of the English teacher to teach language and communication skills, it is no longer solely the job of the computer science teacher to teach programming skills.

Upon sharing my array of apps with some future chemistry teachers, they asked why so many Periodic Tables? My response was “Well not all periodic tables are the same”, upon which was followed by several blank stares...Let me explain: I currently have the following periodic table apps loaded on my iPad...

Just as our lives and various circumstances have a story, so do our laboratory experiences. Often the labs we do lack context but we expect students to buy in to the experiment without knowing the what, where, or why of the story. What makes this lab worth doing? What question(s) are we trying to answer? Why was someone exploring this in the first place?

From the looks of things, we are all in the same boat. Spring fever. I had two groups of students. Both are ending 3rd quarter, looking out a window at the first nice weather we have had in weeks. Most are already planning their spring break vacation and some have left early. Notice, not much talk about chemistry. The curriculum said it was time for stoichiometry for one group and specific heat for another. Just what the kids wanted to do (read with sarcasm).

How can I engage my students (and myself) for the last half of the semester? I read recently that the human attention span in 2015 is 8.25 seconds(link is external), which is down from 2000’s 12-second span. Currently, we are just beneath goldfish, who can attend to one thought for 9 seconds. I’m not sure of the methods of the research study, and I maintain a level of healthy skepticism. However, I admit my thoughts often spring from topic to topic like a bubble gum machine bouncy ball.

Many of you familiar with me will know I have a great affinity for academic competition and was more than a little bit upset when the International Chemistry Olympiad was scheduled for Karachi Pakistan in 2016.
