Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

This kit is a historical overview of American representations of chemicals from the three sisters to the Love Canal. It compares conflicting constructions about nuclear reactor safety, depleted uranium, Rachel Carson and DDT. Through analyzing diverse historic and contemporary media messages, students understand changing public knowledge, impressions and attitudes about chemicals in the environment.

An integrated course stressing the principles of biology. Life processes are examined primarily at the organismal and population levels. Intended for students majoring in biology or for non-majors who wish to take advanced biology courses.

What factors lead to a natural disaster? What causes a famine? Why do cities flood? According to a recent article in The Atlantic, Houston's flooding during the 2017 Hurricane Harvey was primarily caused by impervious pavement which prevents the absorption of water into the land. This example illustrates how nature and society are interlinked, which is the main focus of Geography 30, Penn State's introductory course to nature-society geography. In addition to examining the linkages between human development and natural hazards, this course will also explore human society's connection to food systems, climate change, urbanization and biodiversity. The course will also cover topics of ethics and decision making in order to help students evaluate the tradeoffs of these interconnections.

Geysers and grizzlies and glaciers, oh my. The national parks may be America's best idea, saving the finest parts of the nation for everyone to enjoy forever. What better way to learn about the natural world than to tour the parks with us? We'll explore how the mountains and valleys formed and why they often come with volcanoes and earthquakes. You'll see what really killed the dinosaurs and how we can help save their modern relatives in the parks. With film clips, slide shows, and our geological interpretations of classic rock songs, isn't it time for a road trip?

This course examines the interconnections of international politics and climate change. Beginning with an analysis of the strategic and environmental legacies of the 20th Century, it explores the politicization of the natural environment, the role of science in this process, and the gradual shifts in political concerns to incorporate "nature". Two general thrusts of climate-politics connections are pursued, namely those related to (a) conflict - focusing on threats to security due to environmental dislocations and (b) cooperation - focusing on the politics of international treaties that have contributed to emergent processes for global accord in response to evidence of climate change. The course concludes by addressing the question of: "What Next?

This class provides a historical survey of the ways that people have interacted with their closest animal relatives, for example: hunting, domestication of livestock, exploitation of animal labor, scientific study of animals, display of exotic and performing animals, and pet keeping. Themes include changing ideas about animal agency and intelligence, our moral obligations to animals, and the limits imposed on the use of animals.
