## Ultrasonic Sensors & Graph Matching: Play, then learn

In my physics class this morning, the plan was to have students work through a packet of descriptions of constant velocity motion. Each description was

I have a student that is taking both IB Physics with me and IB Chemistry with another science teacher. The first units in both courses

## Moving in circles, broom ball, and Newton's cannonball

In physics today, we began our work in circular motion. I started by asking the class three questions: When do you feel 'heaviest' on an

## Computation & CAPM - From Models to Understanding

I wrote last spring about beginning my projectile motion unit with computational models for projectiles. Students focused on using the computer model alone to solve

## Same Skills, Virtual Car: Constant Velocity Particle Model

I had everything in line to start the constant velocity model unit: stop watches, meter sticks, measuring tape. All I had to do was find

## Day 1 in Physics - Models vs. Explanations

One of my goals has always been to differentiate my job from that of a paid explainer. Good teaching is not explaining exclusively - though

## 2012-2013 Year In Review – Learning Standards

This is the second post reflecting on this past year and I what I did with my students. My first post is located here. I

## Speed of sound lab, 21st century version

I love the standard lab used to measure the speed of sound using standing waves. I love the fact that it's possible to measure physical

## Visualizing the invisible - standing waves

I wrote a post more than a year ago on a standing waves lesson I did. Today I repeated that lesson with a few tweaks

## Computational modeling & projectile motion, EPISODE IV

I've always wondered how I might assess student understanding of projectile motion separately from the algebra. I've tried in the past to do this, but
