A field of actively growing corn is a great demonstration of the dramatic effect plants can have on our world. The best time for this activity is when the corn is at least chest height in late summer or early fall, depending on the region of the country. If the> do not grow corn in your region, other crops can also show the phenomenon. This demonstration works best when the overall relative humidity is 60% or less.
First, get permission from the landowner before entering a cornfield. Measure the relative humidity in the center of the field and compare it with the relative humidinr outside the field. (Relative humidity is a measure of the relative saturation of water in the air.) What do you notice? Where did that water vapor come from?
