BIOLOGY LESSON--
Humming and Vision

Yet another tool for teachers

by Stephen Drew, AIR staff

Sometimes, students complain that biology is neither fun nor practical . That claim can be countered in many ways. The experiment described here will appeal to even the dullest (in the traditional sense of the word) student.

Many students, and surprisingly many adults, wonder: What is the effect of humming on vision?

The simplest, and most enjoyable, way to find out is to experiment.

After performing the experiment and analyzing the results, students will no doubt enjoy a trip to the library. There they can look up and pore through P.C. Eastman's classic research paper on the subject:

"Effect of Humming on Vision," P.C. Eastman, Nature, volume 222, no. 189, April 12, 1969, p. 164.

You will enjoy your students' taking up your further suggestion that they repeat the experiement again using some of your fellow teachers as research subjects.

Extra Credit Suggestion (2)

Ambitious students will enjoy tackling the more advanced question: What is the effect of whistling while you work?
