anthony,
This is a wonderful exercise as it convincingly demonstrates both how dependent we are with words and at the same time challenges students to think apart from their usual reliance on words. I feel word choice in writing is really a skilled profession. It's much different from casual consverastaion (where, tone, non-verbal cues, and vernacular) all contribute to conveying a message. Great application of the importance of using the senses in learning!
