Years ago, when I was teaching sociology at the University of Vermont, a colleague introduced me to a classroom exercise that he found useful for showing students gender differences. Eventually I wrote it up and Teaching Sociology published it.
The exercise had two parts. The first, labeled "Colors," listed eight colors -- not the easy ones like red, white, and blue, but puce, taupe, teal, mauve, magenta, chartreuse, ochre, and sienna. Students were to match each with one of ten definitions, such as "brilliant yellow" or "brownish gray."
The second half listed eight "Football terms": safety, screen, curl, trap, touchback, lateral, touchdown, and clip. Again we supplied ten definitions, such as "to block out a defensive player from the side after he has crossed the line of scrimmage."
