Compiled and modified for instructional use by: Kate Darby, Western Washington University In 1887, Robert Towne built a metals smelter two and a half miles northwest of El Paso, Texas, across the river from Ciudad Juarez in Mexico and across the state border from several small towns in New Mexico. The smelter, which processed metal ore from regional mines, was quickly acquired by ASARCO (American Smelting and Refining Company) and became an important visual and economic institution in the region. In 1967, following the mantra of environmental regulation at the time—"the solution to pollution is dilution"—ASARCO erected what was then the tallest smokestack in the world: an 828-foot structure visible from much of the region. While the facility provided jobs to many in the region and produced metals important for a range of manufacturing and consumer products, by the 1970s, residents and scientists began to question the other products from the smelter—especially heavy metals pollution.
This case study includes discussion questions and data sources for further information.

I designed this activity as a role-playing game to help students understand both the concept of climate modeling and how the climate system works. Students take on the role of a climate system component, examining their personal reactions to climate stimuli and building a future scenario based on their group's reactions. You can implement this teaching collection as part of the Climate of Change InTeGrate Module, Unit 5, or as a stand-alone activity.

In this activity, students consider how several communities are adapting to climate change-related problems including drought's impacts on agriculture, loss of assets due to climate-related hazards, freshwater availability, and extreme heat waves. They will read brief case studies about agro-forestry, insurance strategies, the "Room for the River" program in the Netherlands, water storage from retreating glaciers, and city planning for heat waves. Based on these examples and knowledge of their own community, they will suggest possible adaptation strategies that will be most beneficial to their area.

This ocean activity is used to help students analyze different solutions to a real-world case study of the problem of using various coastal stabilization structures. It is intended to be used as a small group activity (3-5 students in each group) following a short introductory lecture about coastal processes (especially longshore drift) and the different types of coastal stabilization structures (jetties, groins, and breakwaters). At the end of the activity, successful students will be able to critically evaluate the benefits and drawbacks of various types of coastal stabilization structures.

The National Poultry Improvement Plan (NPIP) is an industry, state, and federal partnership that has long played a central role in bettering the health of US poultry and improving the competitiveness of the US poultry and egg industries.[1] The objective of this communication is to report the findings of a case study of the NPIP undertaken in 2018. The primary aims of the study included seeking a more in-depth understanding of the NPIP, clarifying how NPIP differs from and complements the Secure Food Supply Plans for the US poultry and egg industries, and assessing the needs and potential applications for establishing a similar program for the US pork industry (e.g., “US Swine Health Improvement Plan”).

After exploring the “Case of the Disappearing Log,” students will probably never look at a log the same way again. In this activity, students assume the roles of detectives faced with a nature mystery. First, they explore a decomposing log and look for evidence of how the log is changing. They make possible explanations for what might be causing log to disappear. Students then learn about common “suspects”—organisms that decompose wood—and the signature evidence they each leave behind. Students use a Disappearing Log Key to identify which organisms might have left behind which evidence, and use this information to make explanations about what has happened to the log since it was a tree. Finally, students learn that the log isn’t really disappearing, it’s turning into the invisible gases that are part of the cycling of matter in all ecosystems.

This video will help students, particularly those not in AP-level classes, have a practical application for knowing about the major divisions between plants, particularly about the details of plant anatomy and reproduction. Students will be able to :Identify the major evolutionary innovations that separate plant divisions, and classify plants as belonging to one of those divisions based on phenotypic differences in plants. Classify plants by their pollen dispersal methods using pollen dispersal mapping, and justify the location of a _crime scene_ using map analysis. Analyze and present their analysis of banding patterns from DNA fingerprinting done using plants in a forensic context.

Students start this exercise using topographic maps of an area recently visited on a field trip to calculate and consider stream gradient of a major river south of Buffalo, NY. The activity then changes gears to have students work with discharge measurements from this stream. They use these measurements to plot and evaluate a few hydrographs which are used to compare how discharge in this stream can be used to consider how much precipitation was received in a certain year. In this lab, students practice mathematically calculating geomorphic properties of a stream, plotting data, and comparing topographic maps to what they observed on the recent field trip. Designed for a geomorphology course Uses online and/or real-time data Addresses student fear of quantitative aspect and/or inadequate quantitative skills

Bycatch can be defined as the act of unintentionally catching certain living creatures using fishing gear. A bycatched species is distinguished from a target species (the animal the gear is intended to catch) because it is not sold or used. Marine mammals (whales, dolphins, porpoises), seabirds, sea turtles and unwanted or undersized fish are some examples of animals caught as by-catch The incidental capture of these animals can significantly reduce their populations. The most well known example of by-catch may be the unintentional mortality of spotted and spinner dolphins in the tuna fishing industry. "Dolphin-Safe" tuna was a result of this interaction (Be prepared to discuss how this came about with students, as it is something close to their daily lives). One important aspect to consider when discussing this issue is that laws protect some of the animals caught as by-catch (Marine Mammal Protection Act and Endangered Species Act). In this lesson, students will first be shown pictures of entangled marine animals and will discuss the definition of by-catch This will lead to discussions on why by-catching exists, how it impacts specific animals as well as humans, whether the students believe it is an important issue, and how by-catch can be reduced.

In this lesson, the students look at the components of cells and their functions. The lesson focuses on the difference between prokaryotic and eukaryotic cells. Each part of the cell performs a specific function that is vital for the cell's survival. Bacteria are single-celled organisms that are very important to engineers. Engineers can use bacteria to break down toxic materials in a process called bioremediation, and they can also kill or disable harmful bacteria through disinfection.

Students color-code a schematic of a cell and its cell membrane structures. Then they complete the "Build-a-Membrane" activity found at http://learn.genetics.utah.edu. This reinforces their understanding of the structure and function of animal cells, and shows them the importance of being able to construct a tangible model of something that is otherwise difficult to see.

Students learn about the different structures that comprise cell membranes, fulfilling part of the Research and Revise stages of the legacy cycle. They view online animations of cell membrane dynamics (links provided). Then they observe three teacher demonstrations that illustrate diffusion and osmosis concepts, as well as the effect of movement through a semi-permeable membrane using Lugol's solution.

In this unit, students look at the components of cells and their functions and discover the controversy behind stem cell research. The first lesson focuses on the difference between prokaryotic and eukaryotic cells. In the second lesson, students learn about the basics of cellular respiration. They also learn about the application of cellular respiration to engineering and bioremediation. The third lesson continues students' education on cells in the human body and how (and why) engineers are involved in the research of stem cell behavior.
