Introduction
The PASCO Model SF-8563 Molecular Motion
Demonstrator is used to model the behavior of gas
molecules in a closed container. The molecules of the
gas are represented by fifty-one steel ball bearings. In
the kinetic theory of gasses, as a gas is heated, the
random kinetic energy of the molecules increases,
increasing the pressure of the gas on the sides of the
container. In this demonstration, kinetic energy is
imparted to the ball bearings by a vibrating plunger
which fits into a slot in the bottom of the container.
Operation
➤ Note:
The SF-8563 Molecular Motion Demonstrator is
designed to be used with a wave driver. The
wave driver must be powered by a function
generator capable of delivering at least 0.5 A of
current into an 8
Ω
load. (We recommend the
PASCO Model PI-9587A Function Generator/
Amplifier or PI-9598 Student Wave Generator.)

➀ Set up the Molecular Motion Demonstrator as
shown below, but leave the pressure plate out for
now.
The banana plug connector on the plunger mates
with the drive arm of the wave driver. The base of
the ball bearing container then mounts to the top of
the wave driver using the thumbscrews to hold it in
place. The plunger slides through the slot in the
