Mr. Landgreen

I'm a high school science teacher at New West Charter School. This is my teacher home page.

Physics - notes

Physics is science. One of the most fundamental scientific disciplines, physics investigates how matter and energy change over space and time.

Physics advances technology. Physics is behind all the different technologies in a cell phone. Physics explains how electromagnetic waves encode information between a cell phone and tower, how electricity in the computer chips is controlled by transistors, resistors, and other elements, how a phone's speaker produces changing waves of air pressure, and how a phone uses GPS to know its position.

Physics guides engineering. A knowledge of physics allows engineers to predict how reality behaves, which helps them design, tinker, and experiment

Physics speaks with math. Math is the language physics uses to predict and communicate the nature of our universe.

Computer Science - codepen

The class focuses on learning the fundamentals of computer science through project based learning.

About Me

I graduated from University of Georgia with a B.S. in physics and astronomy. After college I moved to Los Angeles and got credentialed to teach high school physics and chemistry. I’ve been teaching physics, chemistry, and computer programming in California since 2006. Before joining New West I was both the dean of students and chemistry teacher at SLO Classical Academy.

I nerd out on: books, hiking, soccer, science, coding


Photos: mostly physics experiments.

Codepen: some of my HTML/CSS/JavaScript experiments

n-gon: a physics platformer I wrote in JavaScript

bells: the school bell schedule for today

Scratch: more games I wrote


If you were absent check in to see what you missed. The best time to meet with me is after school.
