Suggested Experiments
Experiment 1: Solar Heating and the Greenhouse Effect
Part I: Solar Heating
1. Mount the box with plate
to a rod stand, such that
the Sun's angle is
perpendicular to the
aluminum plate and the
white plastic knob has no
shadow. Keep the black
side of the aluminum
plate facing up (See
Figure 4).
2. Use a PS-2000 Xplorer
or a laptop computer for
data collection. Set the sample rate in either Xplorer or DataStudio
for 2 Hz.
3. Have a piece of cardboard available to shade the box while setting
up.
4. In DataStudio, click the Start button to begin data collection and
remove the cardboard shade.
5. With the plastic cover on, take a run of data in DataStudio. Let the
box heat until the temperature levels off. (The approximate
duration is 10 to 30 minutes, depending on the outside temperature
and the intensity of the sunlight.)
Equipment Required
Energy Transfer - Solar (ET-8593) Temperature Sensor (PS-2125)
or Thermistor Sensor (CI-6527A)

CAUTION: Overheating
the box may permanently
damage the thermistor
and the plastic lid. The
thermistor’s maximum
temperature capacity is
135 o C.
