ON the surface it appears to be about the ripening and death of fruits and vegatables. However, I believe if one reads the article over a second time, and preforms the actual lab, yeu will realize that the articel can apply to many aspects of change in the environment related to why certain plants do not bloom or reproduce when they should, or die out when the environment they exist in goes under variouis stresses. 1st) A nice connections is made withe the four variables to plant physiological change. They are: a) Concentratins of atmospheric gasses - (This alone requires extensive study, and can be made into numerous scientific inquiries. b) Disease. Also diseases form other plants can place stress directly on a target plant or..place sturess on a different plant that has shared symbiotic microbial connections, thus indirect affects. C) Temperature. (This is the only obvious variable) D) Plant hormones in lesser or more concentration. This of course can relate directly back

This article describes how to use fruit and vegetable spoilage bio¬chemistry principles to teach scientific reasoning skills. The article includes teacher background information, safety cautions, procedure and extensions from the college publications from NSTA. The results are shown in a photo for a potato. I believe this would be useful for a college lab or perhaps an AP course.
