# Day 3: Starting Particle Physics

My Modern Physics class started thinking about particle physics with the gold foil experiment. We used another QuarkNet Data Portfolio activity and simulated the experiment using marbles as the alpha particles and dice as the gold atoms. They made a histogram of hits per 10 rolls by using sticky notes on the wall, then figured out the size of the particles (the dice and marbles are … Continue reading Day 3: Starting Particle Physics

# Day 2: “Where something is” and Lighting Bulbs

One section of Physics 10 had its second day today. We articulated what position was and did a second take of the buggy lab with measurements of position instead of distance. Another amazing board meeting happened by the end of class, along with some beginnings of realizations about how important units really are for communication. (“How could some of us have a slope of 19 and some … Continue reading Day 2: “Where something is” and Lighting Bulbs

# Day 1: Dice, Histograms, and Buggies

Modern Physics (for 11th/12th graders) started with a variation of a Quarknet Data Portfolio activity to learn how to make histograms and to start thinking about how they could be useful. There were multiple parts to the activity. In one part, they found sums for pairs of dice. They made histograms for their groups, but also pooled data as a class and made one big … Continue reading Day 1: Dice, Histograms, and Buggies

# Day 20: Forces and Jumping

In our last class (which was a week ago), the Mechanics kids had whiteboarded a problem about a student jumping (which I got from Noah Segal, who—in addition to being a great physics teacher—is also a wizard of MS Word art): The discussion (last class) was centered around the first situation. The original whiteboard showed the forces as balanced. Might be tough to see in … Continue reading Day 20: Forces and Jumping

# Day 13: Newton’s 2nd Law Experiment

We started Unbalanced Forces, so now we’re really doing physics! Of course, we started by doing an experiment. It was so cool to jump into our first real pre-lab with kids who’ve been there with me before. I showed them something and they exclaimed, “Observations!” and started listing them before I even really finished showing them the relativity exciting thing. They drew an FBD for the … Continue reading Day 13: Newton’s 2nd Law Experiment

# Day 11: Bear and the Honey and the final day of CAPM

We spent our Mechanics class solving problems and working on good habits (keeping units attached to numbers, using physically meaningful symbols). I let it take up the time today, and I went around to different groups as they worked to get as many people as possible to see how using the slope and the area of the v-t graph wasn’t as overwhelming as it seemed … Continue reading Day 11: Bear and the Honey and the final day of CAPM

# Day 9: Rules for the Direction of the Unbalanced Force

The set of problems today asked students to draw multiple representations based on given velocity-time graphs, but also to say whether the forces were balanced, unbalanced in the positive direction, or unbalanced in the negative direction. After the first problem, one student volunteered a rule (I didn’t prompt this!)—that the unbalanced forces were correlated with the acceleration. That 0 acceleration means balanced forces, positive acceleration means positive unbalanced forces, … Continue reading Day 9: Rules for the Direction of the Unbalanced Force
