Nitinol “Live” Wire
Wire with a memory! Nitinol wire was discovered in 1961 and has “shape” memory.
When placed in cold water it can be bent into any shape. Put into hot water, it springs
back to its original shape. Shape memory alloys are discussed in the provided
instructions. Price is per inch; may be purchased in any length requested.

Conductometer
AP9212
Conductometer
Investigate how different types of metals conduct heat as you hold the center of the
conductometer over a flame. Small amounts of wax placed in wells at the end of each
metal rod melt at different rates demonstrating the relative thermal conductivity of
each metal. The five metal rods are steel, nickel (or iron), aluminum, copper, and
brass. Plastic handle and instructions are provided.

AP9212 Conductometer $22.63
Ball and Ring Apparatus
Perform the classic demonstration “thermal expansion of metal” with this ball and
ring apparatus. Brass ball passes freely through ring at room temperature but when
the ball is heated, it no longer passes through the ring. Plastic or wooden handle
keeps hands cool. Instructions included.

AP9031 Ball and Ring Apparatus $18.54
Linear Expansion Apparatus
Determine the coefficient of expansion of four different metals. The dial indicator on
this newly engineered linear expansion apparatus will provide more accurate and
reproducible results and is more accurate than the old micrometer form. This quality
instrument is easy to set up, use and store. Includes an aluminum base and heating
jacket with three nipples for water intake, outlet, and thermometer. The apparatus
comes complete with four different experimental rods and detailed instructions.

Linear Expansion Demonstration
A new twist to an old classic! Demonstrate both linear and volume expansion and
contraction with this simple device. At room temperature, the metal rod fits between
the metal bracket and into the drilled-out holes. However, when the metal rod is
heated, it becomes clearly visible that the rod has lengthened and swelled when it
no longer fits between the metal bracket or into the holes. Reverse the process by
plunging the metal bracket into ice-cold water to show the contraction of cold metal.

Specific Heat Set—
Student Laboratory Kit
By: The Flinn Staff
Heat up five different metal cylinders to exactly the same temperature, add each to a
precise amount of water at known temperature, and observe the water temperature
change. Students perform a lab activity and calculate the specific heat of each metal
specimen. Instructions include background, lab activity procedure, tips and sample
problems. Five cylinders—aluminum, copper, steel, tin and zinc, each with the same
58-g mass and 19-mm diameter—are included in the set.
Complete for 5 student groups. Super Value Kit is complete for 10 student groups.
All materials are reusable.
