Safety
CAUTION: The cube can reach 100 °C (212 °F). Do not touch the cube while
the apparatus is in use. Allow the apparatus to cool completely after use before
handling. Do not apply more than 10 V to the apparatus. Always monitor the temper-
ature when the apparatus is in use. Do not allow the cube to exceed 100 °C. This
apparatus is intended for use by students only under instructor supervision.
Suggested Experiments
The configuration files called for in these activities can be found on the included
CD-ROM. There are three folders, each containing different versions of the files.
Refer to the table below to find the appropriate files for your equipment.
1. Infrared Light Intensity versus Temperature
In this experiment you will measure the IR intensity emitted by the cube as its temper-
ature increases.
Setup
1. Mount the Thermal Cavity on the included base. Connect the Thermal Cavity to
the Thermistor Sensor and power supply (but don’t turn it on yet).
2. Connect both sensors to the interface (or interfaces).

3. Position the IR sensor on a stand or book so that its sensitive element is 2 cm
from the black surface of the cube.

If you are using a
ScienceWorkshop inter-
face, connect the IR sen-
sor to Channel A and the
Thermistor sensor to
Channel B; connect the
Power Amplifier (if used)
to Channel C; set the
gain of the IR Sensor
to 1.
