Atoms in Motion
Scott Johnson
University of California, Davis
At first glance, it looks like a renegade screen saver. A colorful collection of balls bouncing around the screen. But Atoms in Motion is all about serious science. This interactive simulation software shows solids, liquids, and gases modeled as atoms—which are represented as balls—in a contained space and explores how they act and interact under different conditions. The program displays a real-time, three-dimensional animation of the atoms in a variety of scenarios. Students can change parameters in each simulation, watching as the quantitative effects appear on screen. Variable parameters include the number, diameter, mass, color, charge, and bond strength of each atom; the position and velocity of each atom; the size and temperature of the box; and any external pressure, such as a piston.
Atoms in Motion adopts a multilevel approach to its subject matter, making it widely suitable for introductory high school students through upper division college undergraduates. At a beginner's level, Atoms in Motion presents a "moving picture" of how different substances would look as they undergo change; for example, how a solid would appear at an atomic level as it melts. On an intermediate plane, more intense manipulation encourages exploration of advance concepts such as heat capacity, mean free path length, and Brownian motion. At and level, however, the visual representation really hits home by clearly demonstrating how thermodynamic laws are a direct consequence of a large number of particles pushing, pulling, and colliding with one another.
The user's manual contains a collection of student exercises covering topics like heat capacity of solids and gases, air friction, and air as STP. These exercises are ideal for lab assignments or for use as lecture demonstrations. A short tutorial is included as well, but the program is so easy to use that the interface can be mastered in a matter of minutes! You'll discover that a single lab session provides ample time to work with the gem of a program.
