This guide contains information and activities designed to be used during National Wildlife Week. These curriculum materials are organized into three stages and offer a coherent progression from learning about natural communities through understanding human communities and human responsibilities for natural communities to offering opportunities for community service by students. Stage One activities will help students understand certain ecological principles related to natural communities. From the scientific principles of interconnectedness, niche, and succession, learners are introduced to ecosystems thinking. The next four activities are grouped into Stage Two and focus on human communities as dependent upon and embedded within natural communities. The curriculum culminates in Stage Three activities which allow learners to realize the potentials of community service for human conservation of natural resources. Some activities encompass all age levels while others are directed toward specific age groups. Each lesson plan lists learning objectives, grade levels, time and materials required, and related school subjects. A glossary, resources list, World Wide Web sites, and a list of organizations are also included. (PVD)
