AACT GOVERNING Board Elections 2016

AACT

I wonder how many of the ChemEdX readers are also members of AACT? The American Association of Chemistry Teachers has been a long time coming and is in its second year of operation now. It is currently being supported by the American Chemical Society and is a separate, and much more affordable, membership than ACS. One year of membership is only $50 and includes a subscription to Chem Matters Magazine.

Using the Talk Science Primer in a Chemistry Classroom

TERC: Talk Science Primer

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.

What do you do for AP Chemistry review?

ap exam date May 2

It’s review season for AP courses! I have a love/hate relationship with the date of the AP Chemistry exam. On one hand, it’s SO early. On the other hand, because it’s the first exam, my students actually study for it (compared to later in the AP exam season when students are like, “I’m done. I don’t care anymore.”).

A different way to look at heat and energy....

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.

Use Your Smartphone as an "Absorption Spectrophotometer"

Smartphone spectrophotometer

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!

Coding in Chemistry

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.

Not All Periodic Tables are the Same?

periodic table apps

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...

Tell Me a Story

Tell me a story

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?
