Sixth grade students can prepare for the Multnomah County, Oregon, Outdoor School experience by completing the workbook designed to provide fundamental information about soil, water, plant, and animal resources. The workbook begins with an introduction to environmental manners, after which a section is devoted to each resource area. The glossary of terms and words provided for each area is the basis of many of the learning activities which include charts, matching, drawing, labeling, completing study sheets, and games (bingo, crossword puzzles, word searches, word scrambles). The activities specifically address: the water cycle; crayfish; pH; dissolved oxygen; trees; tree measuring; ecosystems; and land use planning. A Teacher's Guide accompanies the workbook. (SB)
