Building the Constant Acceleration Particle Model (New Paradigm Investigation)

In my Physics 10 update/upgrades, I built a new paradigm investigation for the Constant Acceleration Particle Model. The activity described here gets at the same things as my older activity, but it allows groups to do the investigation rather than the entire class together, and it gives more structure and space to the discussion. The… Read More Building the Constant Acceleration Particle Model (New Paradigm Investigation)

Problem Solving Lab Stations for Unbalanced Forces

After the success of my balanced forces problem-set-replacing mini lab practicum stations, I wanted to design a similar activity for my unbalanced forces unit. One might think that this would be more challenging (or even impossible) to do since these stations need to involve objects with changing velocities (so the handy flip-up index cards wouldn’t… Read More Problem Solving Lab Stations for Unbalanced Forces

“Can we have a group test?” Alternative Assessments in Science Classes (Part 1)

One of the best things about my current school is that the students push me to rethink practices that I’ve taken for granted in the past. They even push me to rethink practices that I’ve put lots of effort and intention into developing, like my final exams. “Can we have a group test?” I’m in… Read More “Can we have a group test?” Alternative Assessments in Science Classes (Part 1)

Tic Tac Bounce

AKA Inventing a New Flavor of Energy Storage When we start the energy unit, we usually pick up 4 flavors (kinetic, gravitational, spring, and thermal) and note that we will recognize and name other ways of storing energy when we see them. That happens pretty immediately when we do pie charts. We run into a problem pretty… Read More Tic Tac Bounce
