We've added more on doing inquiry in your classroom, and more lessons on engaging students in a variety of outdoor activities. Separate guides for Grades K-2, Grades 3-6, and Middle School each include age-specific lessons divided into 6 sections on butterfly life cycles, butterfly systematics, ecology, conservation, conducting experiments, and monarch migration. Each Guide includes extensive background information, with sections on monarch biology, practical tips for rearing and observing insects, and conducting inquiry-based lessons in the classroom. Lessons include both teacher and student pages. There is an appendix with an extensive bibliography, and black-line drawings that can be copied for student handouts or overhead transparencies. K-2 Guide: 233 pages; 3-6 Guide: 342 pages; Middle School Guide: 315 pages.
