## Computational Resources for Teaching

**The OSP Collection** provides curriculum resources that engage students in physics, computation, and computer modeling. Computational physics and computer modeling provide students with new ways to understand, describe, explain, and predict physical phenomena. Browse the OSP simulations or learn more about our tools and curriculum pieces below.

## Tracker

The Tracker tool extends traditional video analysis by enabling users to create particle models based on Newton's laws. Because models synchronize with and draw themselves right on videos of real-world objects, students can test models experimentally by direct visual inspection.

**Coupled Compass Oscillations Video Analysis Activity**

The Coupled Compass Oscillations Video Analysis Activity explores the behavior of a pair of loosely coupled compass needles in air with weak damping. The needles are far enough apart that the magnetic interaction between their magnetic dipoles is much weaker than their interaction with the Earth's magnetic field. The resulting motion displays beats--when one compass is momentarily at rest, the other oscillates with maximum amplitude.

**Copernican Revolution**

A shared file folder of Astronomy models designed for a course on the Copernican Revolution. In this course students explore the history of astronomy from the Ancient Greeks to Isaac Newton. Astronomical theories are studied in some detail and evaluated based on their success or failure at reproducing astronomical observations. The EJS simulations in this folder allow students to actively engage with the astronomical theories and visualize the apparent motions predicted by each theory.

## EJS Modeling

Student modeling, the guided exploration of physical systems and concepts, is a powerful approach to engaged learning. Easy Java Simulations provides the computational tools for students and faculty to explore physics without the need for learning details of java programming.

**Zeeman Heartbeat Model**

The Zeeman Heartbeat Model uses work in Catastrophe Theory to create a simulation of the heartbeat cycle. The heart is represented as a blue circle in phase space and travels from diastole to systole which are represented as the green circles. Cardiac muscle fiber length (x) is represented on the y-axis and electrochemical activity (b) is represented on the x-axis. The model calculates the heart rate (in beats per minute) and a variable called gamma which is intrinsic to the pacemaker.
