## Building the Electrical Current Model with The Amazing \$25 Programmable Power Supply

Not Just For Teaching Robotics Thanks to the generous donations of supporters of the Physics Academy, we were able to purchase a new set of Arduino Uno micro-controllers for use in this year’s robotics competition. As I was planning out the unit on teaching DC circuits, I realized that some of our DC power suppliesContinue reading “Building the Electrical Current Model with The Amazing \$25 Programmable Power Supply”

## Investigating The Projectile Particle Model

The Class Designs The Deployment Experiment The video above shows the recent deployment activity where students predicted the vertical position of a projectile (a Hot Wheels car) as it traversed a known horizontal distance. The student predictions are identified by green sticky notes on the the left hand side. The students first had to workContinue reading “Investigating The Projectile Particle Model”

## A Modernized Bridge Design Contest

Modernizing An Old Classic We have just completed the second project in the Academy for the 2014-15 school year. It was a huge success! This project takes a classic physics project and “upgrades” it by incorporating modern engineering design technology and fabrication techniques. We started with a great project that is now available online throughContinue reading “A Modernized Bridge Design Contest”

## Simulating Planetary Motion (Using Code!)

Simulating Newton’s Law of Universal Law of Gravity Interactive simulations (like those created by the University of Colorado – PhET) can be really nice for impressing students, and giving them a way to explore the dynamics of a simulation. If incorporated into a lesson well, they can add to the active learning process. The questionContinue reading “Simulating Planetary Motion (Using Code!)”

## We Have Lift Off!

This is a follow up post to Modeling A Rocket’s Journey – A Synthesis where I described how the students in the first year program were engaged in creating a predictive report for their model rockets. I want to emphasize that these model rockets were not kits. Each rocket was designed using 3D CADContinue reading “We Have Lift Off!”
