This 11-minute video examines the Exxon Valdez and BP Deepwater Horizon oil spills which revealed a pattern of inconsistent oversight that environmentalists say raises questions about our preparedness for future oil spills.
What are the roles and responsibilities of government and business in preventing and responding to environmental contamination, like the two major oil spills in 1989 and 2010 in U.S. waters? What preparations and preventive measures by private industry and government could help to prevent disasters that affect coastal communities for years?

In this activity, students will learn about different measures of biodiversity: richness, Shannon diversity index, and evenness. Students will begin by calculating these indices by hand using a very small sample data set. Students will then read an overview of the Northern Lakes and Forests and Southern Wisconsin Till Plains, two different Wisconsin ecoregions, and use Google Sheets or Microsoft Excel to calculate and compare biodiversity from a Snapshot Wisconsin database

As students learn about the creation of biodomes, they are introduced to the steps of the engineering design process, including guidelines for brainstorming. Students learn how engineers are involved in the design and construction of biodomes and use brainstorming to come up with ideas for possible biodome designs. This lesson is part of a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

Through an overview of the components of the hydrologic cycle and the important roles they play in the design of engineered systems, students' awareness of the world's limited fresh water resources is heightened. The hydrologic cycle affects everyone and is the single most critical component to life on Earth. Students examine in detail the water cycle components and phase transitions, and then learn how water moves through the human-made urban environment. This urban "stormwater" water cycle is influenced by the pervasive existence of impervious surfaces that limit the amount of infiltration, resulting in high levels of stormwater runoff, limited groundwater replenishment and reduced groundwater flow. Students show their understanding of the process by writing a description of the path of a water droplet through the urban water cycle, from the droplet's point of view. The lesson lays the groundwork for rest of the unit, so students can begin to think about what they might do to modify the urban "stormwater" water cycle so that it functions more like the natural water cycle. A PowerPoint® presentation and handout are provided.

Students investigate how different riparian ground covers, such as grass or pavement, affect river flooding. They learn about permeable and impermeable materials through the measurement how much water is absorbed by several different household materials in a model river. Students use what they learn to make recommendations for engineers developing permeable pavement. Also, they consider several different limitations for design in the context of a small community.

Students learn about population density within environments and ecosystems. They determine the density of a population and think about why population density and distribution information is useful to engineers for city planning and design as well as for resource allocation.

A key component of wildlife management is understanding the impact that humans have on their surrounding environment. In this activity students will begin to explore the human impacts that their school yard is experiencing from air, soil, and water pollution.

Echolocation is the ability to orient by transmitting sound and receiving echoes from objects in the environment. As a result of a Marco-Polo type activity and subsequent lesson, students learn basic concepts of echolocation. They use these concepts to understand how dolphins use echolocation to locate prey, escape predators, navigate their environment, such as avoiding gillnets set by commercial fishing vessels. Students will also learn that dolphin sounds are vibrations created by vocal organs, and that sound is a type of wave or signal that carries energy and information especially in the dolphin's case. Students will learn that a dolphin's sense of hearing is highly enhanced and better than that of human hearing. Students will also be introduced to the concept of by-catch Students will learn what happens to animals caught through by-catch and why.

NUTSHELL: In the optional Field Enhancement portion of the lesson, the class explores the living and nonliving parts of a forest while on a hike. Students spend individual quiet time observing and drawing parts of a forest. In main portion of the lesson, students match plant species with forest ecosystems and learn that living things are influenced by the nonliving things around them. They create a song or skit to show what they have learned about living and nonliving connections. The students conclude the lesson by creating a mural of different types of Wisconsin forests. BIG IDEAS Forests are ecosystems characterized by a dominance of tree cover and they contain a variety of other organisms (e.g., other plants, animals).Forests differ in composition (species within a forest) and structure (layers in a forest). These are both affected by biotic (e.g., animals, plants, humans) and abiotic (e.g., soil moisture, sunlight, climate) factors. OBJECTIVES Upon completion of this lesson, students will be able to: Explain how living things in a forest depend on nonliving things.Recognize that all forests do not contain the same plants and animals. SUBJECT AREAS: Arts, Language Arts, Science LESSON/ACTIVITY TIME Total Lesson Time: 190 minutes (including optional Field Enhancement)Time Breakdown: Field Enhancement (optional)--50 minutes; Introduction--15 minutes; Activity 1--35 minutes; Activity 2--45 minutes; Conclusion--45 minutes TEACHING SITE Classroom; well-forested site for optional Field Enhancement

Students are introduced to the concept of a dam and its potential benefits, which include water supply, electricity generation, flood control, recreation and irrigation. This lesson begins an ongoing classroom scenario in which student engineering teams working for the Splash Engineering firm design dams for a fictitious client, Thirsty County.

Students experience civil and environmental engineering by planning a housing development in an existing biome, while also protecting the native species that live there. They conduct research, draw plans, make brochures and give presentations, with each team having a member serving as a project manager, civil engineer, environmental engineer and graphic designer. The best designs creatively balance the needs and resources necessary to support both the native species and human infrastructure.

Students perform a macroinvertebrate survey to gauge the health of a local river. They collect water samples and count macroinvertebrates to learn how the health of a river's ecosystem can be determined by its river insect population.
