2. Press
c to see the available sample rate units for that sen-
sor. Highlight “minutes” using the arrow keys and press
c.
3. Use the arrow keys to highlight Sample Rate and press
c.
Change the sample rate to 1, 2, or 5 minutes between sam-
ples.
4. Use the arrow keys to highlight the sensor in port 2. Press
c to select that sensor, and repeat steps 2 and 3 to change
the sample rate. Do this for the remaining sensors.
Data Collection
1. Ensure that the GLX is in Continuous data collection mode.
a. Press h+I to access the Sensors screen.
b. Press
F to access the Mode menu. If necessary, use
the arrow keys to select Continuous and press c.
2. With the sensors in place, press

3. Allow the experiment to run for the specified time. Do not
bump or jar the EcoZones, as this may cause the sensors to
record erratically.
4. Press
s to stop collecting data.
Data Analysis
Graphs showing two variables changing over time are most valu-
able in the EcoZones experiments because they show the rela-
tionship between related quantities, such as oxygen and carbon
dioxide concentrations, and how these relationships changes over
time.
Example Activities
• Construct a traditional ecosystem with a aquatic, terrestrial,
and decomposition chamber.
• Construct a single biome, such as a desert, trundra, or man-
grove biome.
• Monitor the effects of light on the photosynthesis of a plant
in a single chamber.
Sample Data
This graph shows how the concentrations of oxygen (black) and
carbon dioxide (gray) change as a light is turned on and off.
This graph shows how the relationship between the relative humidity
(black) and temperature (gray) within a terrestrial chamber over a
24-hour period.
