Units 5 & 6

By | July 2, 2016

Unit 5: Counting Particles No real changes to this unit. I added Mole Challenges as extra hands-on practice. Unit 6: Particles with Internal Structure We generally followed a traditional sequence. Some changes: We discussed Coulomb’s Law, as they didn’t do it in last year’s physics classes. This helped with the sticky-tape lab quite a bit. This […]

Units 3 & 4

By | July 2, 2016

Unit 3: Energy and Moving Particles (duration: ~2 weeks, or 8 class meetings) Since the first bit of the traditional “Unit 2” was covered in the previous unit, this unit starts with pressure. Otherwise, there was no real modifications to the normal sequence. Unit 4: Describing Substances (duration: ~2-3 weeks, or 10-12 class meetings) We started this […]

Unit 2: Energy and States of Matter (Duration: ~ 3 weeks, or 13 class meetings)   This unit began relatively normally, with diffusion demos and storyboards. We watched the Eureka! videos, and we discussed measuring temperature, and how to represent cold and hot particles in motion. We had a great discussion on our particle representations, […]

New(ish) beginnings and reflection on my first unit

By | November 8, 2015

I’m currently in my 8th year of teaching, 7th year of teaching Chemistry, and 5th year as a modeler. It is not an exaggeration to say that my experience with modeling has changed my entire teaching philosophy, and the way that I relate with students. It has also had an impact on how I teach chemistry not only at […]

As I headed over to my blog dashboard, I realized it has been almost exactly a year since I last posted. And, funny enough, I am exactly where I left off. I am back at Taft School, this time for a two-week AP chemistry workshop. The main difference is this time I actually will be […]
