The information contained in this resource and activity book follows a learning cycle that includes: a) free exploration by the students; b) expansion of exploration through activities that allow children to test, integrate, and sort out their discoveries; and c) application of concepts through individual and group projects which provide students with the opportunity to enhance and share what they have learned. Each section includes teacher resource material, planned lessons, suggested forest log entries, and expansion activities. Students will look at collected samples, books, magazines, and other resources. The display table's contents will motivate curiosity and questions. Watch carefully during this stage for high-interest items and concepts. Four transparencies (print books) or PowerPoint slides (eBooks) are included to engage students in discussion and reinforce the concepts presented in the book.

A forest is unlike any other biome on Earth. There are many life cycles found within a forest. Learn about the energy pyramid that explains the numbers of forest plants and animals. Learn about threats to these lively forests and how they thrive and survi

The information and activities in this resource book enhance children's knowledge and awareness of the components of tundra environments, including physical and biological characteristics. Students will discover where the tundras are located on our planet. They will find out what characteristics tundra environments have in common, what lives there, and how living things survive there. As they explore tundra organism adaptations, students will discover similarities and differences between living things in the tundra and those in other ecosystems. Engaging in activities that emphasize the ecology of plants and animals, food chains and food webs, and survival, students will begin to relate the structure of living things to their roles in the ecosystem. Four transparencies (print books) or PowerPoint slides (eBooks) are included to engage students in discussion and reinforce the concepts presented in the book.

The information and activities in this resource book enhance children's knowledge and awareness about the components of a grassland environment, including physical and biological characteristics. Students will discover where grasslands are located on our planet. They will find out what features grasslands have in common, what types of organisms live there, and how they are adapted to survive. As they explore grassland organism adaptations, students will discover similarities and differences between living things in grasslands and those in other ecosystems. Activities that emphasize the ecology of plants and animals, food chains and food webs, and survival will enable students to relate the structure of living things to their roles in the ecosystem. Four transparencies (print books) or PowerPoint slides (eBooks) are included to engage students in discussion and reinforce the concepts presented in the book.

Each section includes teacher resource material, planned lessons, and expansion activities. Students will examine various items, books, and resources. The display table's contents of fruits, nuts, woods, and other rainforest items will pique students' interest. Four transparencies (print books) or PowerPoint slides (eBooks) are included to engage students in discussion and reinforce the concepts presented in the book.

The information and activities in this resource book enhance children's knowledge and awareness about the components of a desert environment, including geography, soil and other geological characteristics, weather, plants, and animals. Students will discover where deserts are located in the world. They will find out what characteristics these deserts have in common, what lives there, and how the living things survive. Activities that emphasize plant and animal interdependence, food chains, and protection will enable students to relate the structure of the animal's body to functions necessary for its survival. Students will also begin to discover how they, as humans, would react to living conditions in a desert environment. Four transparencies (print books) or PowerPoint slides (eBooks) are included to engage students in discussion and reinforce the concepts presented in the book.

A series of concise books, each by one or several authors, will provide prompt, world-wide information on approaches to analyzing ecological systems and their interacting parts. Syntheses of results in turn will illustrate the effectiveness, and the limitations, of current knowledge. This series aims to help overcome the fragmen tation of our understanding about natural and managed landscapes and water- about man and the many other organisms which depend on these environments. We may sometimes seem complacent that our environment has supported many civilizations fairly well - better in some parts of the Earth than in others. Modern technology has mastered some difficulties but creates new ones faster than we anticipate. Pressures of human and other animal populations now highlight complex ecological problems of practical importance and theoretical scientific interest. In every climatic-biotic zone, changes in plants, soils, waters, air and other resources which support life are accelerating. Such changes engulf not only regions already crowded or exploited. They spill over into more natural areas where contrasting choices for future use should remain open to our descendents-where Nature's own balances and imbalances can be interpreted by imaginative research, and need to be.
