This resource contains presentations from one of the Center for Automotive Research's (CAR's) breakfast briefings titled "Automotive Fuels and Emissions: Policies, Compliance, & Potential Impact of Future Technologies." This briefing occurred on 12/5/13 at Robert Bosch LLC in Farmington Hills, MI. At the briefing presenters discussed the strategic implications of Tier 3 regulations which will soon be finalized and may impact future technology decisions in a multitude of ways. The impact of Tier 3 emission regulations is expected to be far reaching as they have the potential to influence the quality of fuel, as well as usage of alternative fuels and powertrains. Further, the regulations will have a direct influence on the technologies, such as diesel and gasoline direct injection, that automakers will utilize to meet the fuel economy standards through MY2025. Included in this resource are the presentations from the National Renewable Energy Laboratory (NREL), Volkswagen, and Bosch utilized at the briefing.

In this lesson, students expand their understanding of solid waste management to include the idea of 3RC (reduce, reuse, recycle and compost). They will look at the effects of packaging decisions (reducing) and learn about engineering advancements in packaging materials and solid waste management. Also, they will observe biodegradation in a model landfill (composting).

As the carbon dioxide concentration of our atmosphere increases and our climate warms, the hay fever season seems to be getting longer and more severe. In this case study, students assume the a role of a public relations specialist contracted to communicate the link between climate change and pollen allergies. The activity focuses on the importance of scientific skills to careers outside science, and is most suitable for a lower-level introductory biology, human health, or environmental science course.

Soilless cultivation is recognized globally for its ability to support efficient and intensive plant production. While production systems vary| most utilize a porous substrate or growing medium for plant provision of water and nutrients. Until relatively recently| the main drivers for the selection of the component materials in growing media were largely based on performance and economic considerations.

Acid rain occurs when the pollutants that come from immobile sources such as smokestacks, power plants, and mobile sources such as cars rise up into the clouds and fall back to earth as contaminated rainfall. The rain becomes acidic because of gases which dissolve in the rain water to form various acids. Rain is naturally slightly acidic because of the carbon dioxide dissolved in it.  Acidic water contains an excess of hydrogen ions. Absolutely pure water contains equal numbers of acidic and basic ions (H+ and OH-). This gives rain a pH of around 5.0. Acid rain is formed by the reaction of rain water to a combination of various gases. Acid rain has some rather disastrous consequences on human, plant and animal life. Kindly find the attachments for more knowledge about the acid rain.

Commercial fishing nets often trap "unprofitable" animals in the process of catching target species. In this activity, students experience the difficulty that fishermen experience while trying to isolate a target species when a variety of sea animals are found in the area of interest. Then the class discusses the large magnitude of this problem. Students practice data acquisition and analysis skills by collecting data and processing it to deduce trends on target species distribution. They conclude by discussing how bycatch impacts their lives and whether or not it is an important environmental issue that needs attention. As an extension, students use their creativity and innovative skills to design nets or other methods, theoretically and/or through hands-on prototyping, that fisherman could use to help avoid bycatch.

Bycatch, the unintended capture of animals in commercial fishing gear, is a hot topic in marine conservation today. The surprisingly high level of bycatch about 25% of the entire global catch is responsible for the decline of hundreds of thousands of dolphins, whales, porpoises, seabirds and sea turtles each year. Through this curricular unit, students analyze the significance of bycatch in the global ecosystem and propose solutions to help reduce bycatch. They become familiar with current attempts to reduce the fishing mortality of these animals. Through the associated activities, the challenges faced today are reinforced and students are stimulated to brainstorm about possible engineering designs or policy changes that could reduce the magnitude of bycatch.

In this decision case, a congressional staffer must weigh a number of competing concerns and issues, including popular reactions to genetically modified organisms, in deciding how to present information to her boss, an influential congressman drafting legislation to support agricultural research. The case explores the social and biological issues surrounding micronutrient malnutrition, including deficiencies of several vitamins and essential minerals, especially iron, iodine, and vitamin A, which affect at least one-third of the world's population, primarily in developing nations. Developed for a graduate-level seminar on "Genomics, Agriculture, Food Systems and Development," the case teaches about the issues surrounding genomic applications in agriculture and their implications to health, environmental stewardship, economic sustainability, and national development.
