WARD’S Modeling States of Matter Activity Model |
Examine Different States of Matter Under Varying Conditions |
A motor driven piston operates in a chamber with a movable piston closing the other end. Varying the speed of the motor changes the “temperature” of the particles being driven by the lower piston, while the upper piston defines the volume occupied by the sample. At low temperatures, the particles cling to one another with a stable shape as they model the solid state of matter. When the temperature is raised a bit, the particles still cling to one another and occupy the same volume, but the shape of the sample becomes fluid at the onset of the liquid state. At still higher temperatures, the same particles become truly independent and model the familiar ideal gas behavior and laws. Other particles are included for introductory purposes and to gather further data on the behavior of an ideal gas. This kit mounts a mechanical driver on an included support stand. It includes a demonstrator for one setup, manuals, and teacher notes. Size: 6″L x 5″W x 9 1/2″H.
