### Physics Soul-mates

The day-to-day work in my class happens in at tables in an “individually together” manner that I described in the Whiteboarding Mistake Game: A Guide post. Quick summary of “individually together”: Students work at tables on problems in their packets. They mostly work on their own, take a moment to consult and debate with the … Continue reading »

### Building the Constant Velocity Model

Note: This post details my version of the paradigm experiment for what is Unit 2 (Particle Moving with Constant Velocity) of the Modeling Instruction Mechanics curriculum. My interpretation varies a bit from the official materials, and my classes build this as their first model, starting with the very first day of school. Here’s a binder. And the handshake. [As … Continue reading »

### Empirical Force Laws: Spring Force Experiment

In the middle of our Balanced Forces unit, we do a couple of experiments to come up with equations for some of the types of forces we’ve been talking about while drawing qualitative free body diagrams. We tend to do them at the same time and to post-lab them together. I covered the gravitational force last … Continue reading »

### Empirical Force Laws: Gravitational Force Experiment

In the middle of our Balanced Forces unit, we do a couple of experiments to come up with equations for some of the types of forces we’ve been talking about while drawing qualitative free body diagrams. We tend to do them at the same time and to post-lab them together. I’ll split them over two … Continue reading »

### Energy Pie Charts

The stage is set. We started building the energy transfer model (ETM), and we’ve talked about the flavors of energy. We are ready for a new representation to help us start thinking about energy storage in a system. In a day or two, we’ll be using energy bar charts, but first, we’ll get used to … Continue reading »

### All-year Goal-less Problems for Physics Class

So. Josh* took my Honors Physics exam review activity and expanded it into something bigger and better. As I was reading his post, though, I started thinking about my regular physics classes. They would really like something like that. Of course, I also had to make it my own. I am curating a set of … Continue reading »

### Balanced Forces before Constant Acceleration

I know you’ve been there. Stuck in the doldrums of kinematics. “It’s against the law to think in the doldrums!” So there you are. Stuck in description-land. The juicy parts of physics (explain and predict) are far away and out of reach. You can easily spend ages and ages there. The students start to think … Continue reading »

### Updated Advice from Former Physics Students

One of my favorite pages that comes included in the new (delicious) binders I hand to students on the first day of school is the Advice from Past Students handout. Everything included on the page is actual advice from actual former students (contributed through course evaluations). For the 2013 crew, I’ve changed the layout to … Continue reading »

### May Course Evaluations: What did you learn in physics class this year?

Next up on the May course evaluation tour: The most important things about this year’s physics classes. These responses are always some of my favorite to read. I’m also including the answers to the question “What are you most proud of with respect to your work in physics class this year?” These responses are typically … Continue reading »

### LinReg for physics class data graphing

What is LinReg and how can I get it? Note: This is not meant to be an advertisement. I was in no way solicited by, nor am I affiliated with, the creator of the program. This is a recommendation and love letter about a tool that has made a huge difference in my classes this … Continue reading »
