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.


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.

Projectile Motion with Angry Birds
The Projectile Motion with Angry Birds lab uses the original video from Rovio, the makers of Angry Birds and the Tracker video analysis tool to measure and analyze the motion an angry bird projected from a slingshot to hit a pig. This OSP item was inspired by Rhett Allain's Dot Physics, a physics blog for Wired.

Curriculum Packages

OSP curriculum packages combine computer simulations with tutorial materials and student worksheets. Packages can be modified to meet the needs of faculty and students

Featured Curriculum Package

Featured OSP Resource

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.
