Demonstrate Phase
Changes of CO2
By: Walter Rohr, Retired,
Eastchester H.S., Eastchester, NY
Using a unique device called a Triple Point of CO2
Apparatus, all three phases of CO2 can now be
easily and safely observed. The apparatus comes
with a large pressure gauge to monitor the pressure changes in the apparatus.
Concepts: Equilibrium, phase diagrams, triple point, sublimation.
Note: Dry ice is required, but not provided.

Hot and Cold Equilibrium—
Le Chatelier’s Principle
By: Walter Rohr, Retired,
Eastchester H.S., Eastchester, NY
Pour some violet-colored solution into three different test
tubes. Place one tube in cold water—the solution turns
pink. Place another tube in hot water—the solution turns a
deep blue. Leave the third tube at room temperature—the
solution remains violet.
Concepts: Equilibrium, Le Chatelier’s Principle, density,
absorption/transmission.

Fluorescence/Phosphorescence
Energy in Photons
By: Rhonda Reist, Olathe
North H.S., Olathe, KS
In this teacher-developed kit, light is shined
through a rainbow of filters onto a piece of
phosphorescent material. The filters absorb
some wavelengths of the light and transmit others.
Concepts: Phosphorescence, transmittance, absorption, emission.

AP4576 Energy in Photons—Demonstration Kit $33.38
Fluorescent Dye
By: The Flinn Staff
Under normal white light in the laboratory,
these solutions appear colorless,
yellow, orange and pink, but when the
lights are turned off and a black light
is shined on them, they glow—and
with different colors!
Concepts: Fluorescence, absorption,
emission, electronic structure,
spectroscopy.

AP9030 Ultraviolet Lamp, 18" 50.63
The Glowing Germ
Contamination
By: Rhonda Reist, Olathe North H.S., Olathe, KS
Place a small quantity of glowing lotion on an
object in the lab. Turn off the lights and turn on an
ultraviolet (black) light. Students will be amazed at
the glowing contamination.
Concepts: Fluorescence, epidemiology, laboratory hygiene safety.
Note: Ultraviolet light and a completely dark room are necessary for demonstration.

Diffusion of Gases—Kinetic Energy
By: The Flinn Staff
Demonstrate the motion of invisible ammonia and hydrochloric
acid gas molecules by their colorful reactions with
acid–base indicators.
Concepts: Diffusion, kinetic-molecular theory.

AP6630 Diffusion of Gases—Kinetic Energy Demonstration Kit $49.40
Seeing the Invisible
By: Jesse Bernstein,
Miami Country Day School, Miami, FL
Is it possible to pour a gas? Set up the specially
designed ramp with equally spaced candles. Add a
clear liquid to the beaker, hold the beaker at the top
of the ramp, and pour the invisible contents. One by
one the candles are snuffed out!
Concepts: Buoyancy, gas density.
