This second K-W-L lesson is an example of how to expand the use of the strategy with topics that have a number of subheadings or categories. To illustrate the concept, the topic GARBAGE and what we can do about it and the book Trash Attack by Candace Savage, published by Douglas and McIntyre, 1990, is used. Any other informational topic of interest to the group may be substituted.
