With a continued focus on the Sonoran Desert, students are introduced to the concepts of food chains and food webs through a PowerPoint® presentation. They learn the difference between producers and consumers and study how these organisms function within their communities as participants in various food chains. They further understand ecosystem differences by learning how multiple food chains link together to form intricate and balanced food webs. At lesson end, students construct food webs using endemic desert species.

Human-caused climate change represents one of the great environmental challenges of our time. As it is inextricably linked with issues of energy policy, a familiarity with the fundamentals of climate change is critical for those looking to careers in the energy field. To appreciate the societal, environmental, and economic implications of policies governing greenhouse gas emissions, one must understand the basic underlying science. METEO 469 serves to lay down the fundamental scientific principles behind climate change and global warming. A firm grounding in the science is then used as a launching point for exploring issues involving climate change impacts and mitigation.

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. \The Atlantic\" needs to be made into a link pointing to this: https://www.theatlantic.com/technology/archive/2017/08/why-cities-flood/538251/"

Geography 431 is designed to further understanding of the natural processes of aquatic ecosystems, management of water resources, and threats to sustaining water quantity. Develop awareness and appreciation of the perspectives about water as a precious resource, commodity, and sometimes hazard. Learn how and why water is distributed unevenly around the Earth. Examine how resource management decisions are strongly related to water availability, quantity, and quality. The course examines water resources management; dams and dam removal; provision of safe potable water; threats to water quantity and quality; land use changes; the water economy; water laws and policy; institutions for water management at the global, national, regional, and local scale; and issues of water security and climate change.

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?
Students explore heat transfer and energy efficiency using the context of energy …
Students explore heat transfer and energy efficiency using the context of energy efficient houses. They gain a solid understanding of the three types of heat transfer: radiation, convection and conduction, which are explained in detail and related to the real world. They learn about the many ways solar energy is used as a renewable energy source to reduce the emission of greenhouse gasses and operating costs. Students also explore ways in which a device can capitalize on the methods of heat transfer to produce a beneficial result. They are given the tools to calculate the heat transferred between a system and its surroundings.

Students learn about geotechnical engineers and their use of physical properties, such as soil density, to determine the ability of various soils to offer support to foundations. In an associated activity, students determine the bulk densities of soil samples, and assess their suitability to support foundations.
Students determine the mass and volume of soil samples and calculate the …
Students determine the mass and volume of soil samples and calculate the density of the soils. They use this information to determine the suitability of the soil to support a building foundation.

Geography 430 is an active, creative learning community focused around understanding the changing relationships between people and their environments, the causes and consequences of environmental degradation, strategies for building a more sustainable world, and the methods and approaches that scholars have used to understand human-environment interactions. The primary course objectives are to help geographers, earth scientists, and other professionals to deepen their appreciation for the complexity of human-environment systems and to develop skills that allow them to interpret, analyze, and communicate effectively regarding human-environment interactions in their lives as students, professionals, and citizens.

Natural Resources Biometrics begins with a review of descriptive statistics, estimation, and hypothesis testing. The following chapters cover one- and two-way analysis of variance (ANOVA), including multiple comparison methods and interaction assessment, with a strong emphasis on application and interpretation. Simple and multiple linear regressions in a natural resource setting are covered in the next chapters, focusing on correlation, model fitting, residual analysis, and confidence and prediction intervals. The final chapters cover growth and yield models, volume and biomass equations, site index curves, competition indices, importance values, and measures of species diversity, association, and community similarity.
