This video segment from the Nevada Department of Wildlife looks at various species of bats and how they impact the environment.

This Nature video segment focuses on the four foods most important to the grizzly bears' survival, and it describes the threats to the supply of each of them.

In this video segment from Nature, learn about the problems bears are creating on ranch land surrounding Yellowstone National Park.

This Nature video segment explores how the relationship between humans and grizzly bears has changed over the course of American History, and it describes the closing of the Yellowstone National Park garbage dumps in the 1970s.

Learn about the precautions humans must take in the face of a growing grizzly bear population in this video from Nature.

This lesson will explore the myths and legends surrounding wolves. We will also investigate factual information about the endangered red wolf.

This Ology game site contains rules and a board for a board game dealing with extinction, particularly the modern biodiversity crisis. The players need to read endangered species facts from the board to answer questions on the spaces that they land in so that they can progress. Users can follow links to what to do and materials needed for the game.

California condors are endangered because they have been poached, or hunted and killed illegally. They are also endangered because of lead poisoning and habitat destruction.

This BioBulletin Web site takes an in-depth look at butterfly farms. The site includes text, videos, photographs, and interviews with key scientists.

This site helps students answer questions about dinosaurs: What makes a dinosaur a dinosaur? Where did they live? What caused their mass extinction? Students can participate in a virtual dinosaur discovery, follow milestones in dinosaur evolution, and see behind-the-scenes slide-shows of the lab environment where vertebrate specimens are prepared for exhibits and research.

This Web site, created to complement the Museum's Dinosaurs: Ancient Fossils, New Discoveries exhibit, offers a virtual visit to the Museum, complete with text, photos, video clips, audio interviews, and more. The site takes an in-depth look at modern paleontology and today's advanced technology.

In this jigsaw, students will graph various Bald Eagle population numbers and determine the impact humans have had on the eagle. Specifically, they will investigate why the Bald Eagle was listed as endangered, the affects of DDT on eagles, and the affects of lead. Based on an original activity titled "Bald Eagle Population Graphing" from The Raptor Center, University of Minnesota http://www.cvm.umn.edu/raptor/prod/groups/cvm/@pub/@cvm/documents/asset/cvm_66866.pdf

Early Image is a collection of extinct-animal paintings and sketches produced before 1923 (and therefore in the public domain). Some of the works are of Victorian age and may lend atmosphere to a class emphasizing the history of geology. The works are divided into two categories; prehistoric life before KT and prehistoric life after KT.

This expedition guide was written as a self-directed tour for the temporary biodiversity exhibit that preceded the museum's Hall of Biodiversity. The site continues to serve as a terrific resource for understanding biodiversity.

This site from the U.S. Fish and Wildlife Service's Endangered Species Program demonstrates how loss of habitat and ecosystems can lead to a decline in biodiversity, and how the Endangered Species Act helps prevent extinction.

This lesson will help your students better understand endangered species. It requires a field trip to the North Carolina Zoological park.

This course will focus on the history of mankind's relationship with the natural world. The student will examine how environmental factors have shaped the development and growth of civilizations around the world and analyze how these civilizations have altered their environments in positive and negative ways. By the end of the course, the student will better understand the reciprocal relationship between human beings and the natural environment and how this relationship has evolved throughout human history. Upon successful completion of this course, the student will be able to: think critically about the historical relationship between humans and the natural environment; identify how early humans modified and adapted natural resources for agricultural and commercial purposes; analyze how human settlements altered the natural environment and evaluate how environmental factors shaped the growth of early civilizations; evaluate how new agricultural and commercial practices altered the natural environment across the globe during the Middle Ages; identify how environmental factors, such as disease and pollution, shaped political and social life in Europe during the Early-Modern Era; evaluate how the Columbian Exchange resulted in significant ecological and biological changes in Europe and the Americas and dramatically altered human societies on both sides of the Atlantic Ocean; analyze the impact of industrialization on human society during the Modern Era and evaluate how governmental and nongovernmental actors have attempted to ameliorate the negative environmental consequences of industrialization; identify current environmental challenges facing humanity and analyze these challenges from a historical perspective; analyze and interpret primary and secondary source documents relating to environmental history using historical research methods. (History 364)

Examines the collision of politics, economics, values, and science in making and carrying out environmental policy at national, state, and local levels. Case studies of environmental policymaking explore the roles of governmental institutions, business, interest groups, the public, and the media in areas of air and water pollution, hazardous waste disposal, public lands management, and wildlife protection. "Environmental Politics and Policy" explores the workings of environmental policymaking in the United States. What are the big issues facing environmental policy? How did we end up with the policies we have today? Why does it take a crisis to move environmental policy forward? Why do political factors - economic interests, social and political values, bureaucratic styles, ideologies, elections, etc. - always seem to overwhelm sound scientific and engineering judgment in determining policy outcomes? Case studies ranging from cleaning up toxic waste pollution to endangered species protection probe the clashes between science and politics at local, state, and federal levels.

Just like the permanent exhibit it was created to complement, the online Hall of Biodiversity showcases the beauty, diversity, and abundance of life on Earth while warning of the threats posed by human activity. Along with a brief introduction to the exhibit, it includes these four sections: Spectrum of Life - A virtual journey through 3.5 billion years of evolution on Earth. The interactive cladogram includes detailed information on more than 25 diverse life forms. Transformation of the Biosphere - An overview of how the Earth is continually experiencing climatic changes and changes brought on by physical events, such as meteorite collisions. The Dzanga-Sangha Rain Forest - An explanation of what visitors will find when they explore this walk-through diorama at the Museum, which features the sights and sounds of a dense tropical rain forest. Solutions - A list of concrete actions individuals can take to help save the Earth's resources for generations to come.
