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.

Featured OSP Resource

Fluorescence Spectra
The Fluorescence Spectra experiment uses Tracker to explore fluorescence and fluorescent lamps. Students observe the spectra directly, measure brightness versus wavelength in Tracker, and answer qualitative and quantitative questions. The spectra include a fluorescent dye, a mercury lamp and two fluorescent lamps, all with red and green laser spots added for easy calibration.

Featured Curriculum Package

Featured OSP Resource

Introductory Astronomy Models
A shared file folder of Astronomy models designed for a college-level introductory astronomy course.  This shared folder contains over 50 EJS models and is broken up into three parts: naked-eye astronomy, classical astronomy (optics and orbits), and modern astronomy.

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.

Gray Scott Reaction Diffusion Model
The Gray-Scott Reaction Diffusion Model displays the spatial concentration of chemical species U and V under the influence of the reaction U+2V->3V and V->P.  The simulation models this reaction in an open system with a constant addition of U and removal of V due to a flow.  Combining this autocatalytic process with diffusion results in pattern formation that has a surprising variety of spatiotemporal patterns when starting in the initial state U=1 and V=0 except for a square grid at the center where U=1/2 and V=1/4.
