Compound Bimetallic Strip
This bimetallic bar will bend dramatically when heated in a Bunsen burner due to the
different thermal expansion rates of each metal used in the bar. Let students examine
the bar and discover for themselves that the two different sides of the bar are different
colors and infer that different metals are fused together. Bar has a convenient
insulated handle. Bar length is 20 cm, overall length is 30 cm.
Catalog No. Description Price/Each
AP5650 Compound Bimetallic Strip $8.93
Stirling Engine
This low temperature difference Stirling engine runs at approximately 150 rpm when
placed over a cup of hot water. Flywheel is 9 cm in diameter and the unit is 14.5 cm tall.
Catalog No. Description Price/Each
AP9708 Stirling Engine $104.00
Steam Generator
Generate steam in a controlled and safe fashion. This steam generator will not break
or rupture since there are no seams. The same aluminum alloy is used throughout to
minimize the problem of galvanic corrosion. The generator includes a wood handled
sample cup and instructions for use.

AP5719 Steam Generator $82.20
Steam Engine
Trace all the energy conversions starting with lighting the match to burning the
dry fuel to converting the water to steam and finally to converting the steam to
mechanical power. Every step of the process can be viewed with this totally visible
functioning steam engine. The accessible drive wheels make powering small electrical
or mechanical devices easy. The engine has a built-in safety valve and comes
with fuel pellets, maintenance tips and complete instructions.

Thermostat Model
This hands-on activity clearly illustrates how a thermostat works by demonstrating
differential expansion. Students heat the bimetallic strip in the model and watch it
bend to make contact, complete the circuit and light the lightbulb. After the strip
cools it bends back, breaks the contact, and turns the light off. A small lightbulb,
socket, wire and dry cell are required and available separately.

Add water to the flask, insert the rubber stopper with exhaust arms, and hang it
securely. Then heat the water with a Bunsen burner and watch the engine spin!
Illustrates important physical principles such as phase changes, pressure, conservation
of momentum and Newton’s third law of motion. Includes a reproducible student
worksheet and complete instructions.

Superheated Steam—
Demonstration Kit
By: The Flinn Staff
Vividly demonstrate the thermal energy content and potential skin burning
hazards associated with steam. Steam is channeled through a copper coil heated
by a Meker burner flame, which raises the temperature of the steam well above
100 °C. Place a piece of paper in the exhaust steam and watch as it chars. Hold a
match head in the exhaust—it will ignite! Includes a reproducible student worksheet
and detailed instructions.
Note: A Meker burner, 250-mL Erlenmeyer flask, hot plate and support stand and
clamp are required and available separately.
