germinate overnight.
•
Reconnect the sensor and put the probe and stopper back
into the neck of the bottle. Do not let the probe or sensor
get wet.
•
Record data for about 10 minutes, and compare the car-
bon dioxide concentration
after
germination to the con-
centration
before
germination.
•
Try the experiment with germinated pea seeds at differ-
ent temperatures.
