("Tales from the Classroom" is a new feature posted occasionally here at this blog. All tales are true and present matters about which I have personal knowledge. The following tale relates the story of something that happened in the mid-1980s)
Jodi had submitted an elaborate plan for testing her hypothesis as to how certain factors affected plant growth. She planted corn in various containers and subjected those containers to different factors.
Jodi on the day of a progress check (frowning with dismay): I may have to change my project. None of the corn I planted is sprouting!
Teacher: Corn is usually very easy to grow. Maybe you planted hybrid kernels. Hybrid kernels do not usually reproduce. Where did you get the kernels you planted? What kind of corn did you plant?
Teacher (incredulously): You planted canned corn? Canning kills the kernel!
Today, Jodi is a state-certified science teacher at the elementary-school level.
