Big Ideas in AP Chemistry: Connections Among Thermodynamics and Equilibrium

revamping a unit

I have a confession: thermodynamics is not my strong suit. The data set I got from the College Board confirmed my lack of confidence in the summer of 2015. With the hope of improvements, I spent some time revamping my thermo unit and I implemented it near the end of last school year. I will share an activity that I feel was quite formative for students and for me in making connections among thermodynamic principles and equilibrium.

 

Henry Ford and Trying Again....

The first few experiments and labs that I use to start the year off are more like “probes”.  I am trying to figure out the strong and weak points for my students. I have found a couple of things we can work on. The two major areas are observations and communication. We need to work on writing sentences that use data and background information to support the theories students develop.

The Importance of Safety.

 Undergraduates Need a Safety Education is the title found in the commentary section of the September 2016 Journal of Chemical Education. It is written by Robert H. Hill Jr and it explains the lack of safety education in chemistry curriculum.  As I read this, I thought back to my safety education that prepared me for my role as a high school chemistry teacher and felt I was very fortunate to have had an undergradutae class that was specifically designed to teach chemical safety. 

Walking in the Footsteps of Scientists Who Came Before Us

I started teaching in a chronological order when I began using Modeling Instruction in my classroom. During the second year of "walking in the footprints of the scientists that came before us", I wanted my students to see where they were walking and a colleague and I came up with the idea of making footprints for each of those scientists and posting them on a timeline.
