provides readings, maps, and visual representations of this battle near Murfreesboro, Tennessee, which was the second bloodiest battle fought west of the Appalachians during the Civil War.

Students construct a three-dimensional model of a water catchment basin using everyday objects to create hills, mountains, valleys and water sources. They experiment to see where rain travels and collects, and survey water pathways to see how they can be altered by natural and human-made activities. Students discuss how engineers design structures that impact water collection, and systems that clean and distribute water.

In this activity, students further investigate major landforms (e.g., mountains, rivers, plains, hills, oceans and plateaus). They build a three-dimensional model of a landscape depicting several of these landforms. Once they have built their model, they act as civil and transportation engineers to build a road through the landscape they have created.

Students explore the impact of changing river volumes and different floodplain terrain in experimental trials with table top-sized riverbed models. The models are made using modeling clay in an aluminum baking pans placed on a slight incline. Water added "upstream" at different flow rates and to different riverbed configurations simulates different potential flood conditions. Students study flood dynamics as they modify the riverbed with blockages or levees to simulate real-world scenarios.

Between 70 and 75% of the Earth's surface is covered with water and there exists still more water in the atmosphere and underground in aquifers. In this lesson, students learn about water bodies on the planet Earth and their various uses and qualities. They will learn about several ways that engineers are working to maintain and conserve water sources. They will also think about their role in water conservation.

This video segment adapted from NOVA explores the effects of the Glen Canyon Dam on the beaches, wildlife, and vegetation of the Colorado River.

describes village life in the Hidatsa and Mandan tribes during the peak of their culture in the early 19th century (North Dakota). It helps students compare information about these seasonally nomadic Plains villagers with the more popularized film and textbook history of nomadic horse-culture Indians such as the Lakota and Cheyenne.

offers information and activities about the American Indians of the Northern Plains who lived in the area of the Knife River where it enters the Missouri. This area is now Knife River Indian Villages National Historic Site.

features stories and resources to help students learn about the heritage of this diverse region. Stories form a picture of the Delta's natural, historic, and cultural resources, and specific subject areas offer more detailed information on the area's role during the Civil War, its plantations, timber industry, and more.

Students will locate 28 rivers within the state of NC, noting names and origins of names, directions of flow, navigability, and development of population centers in relation to the rivers.

In this activity, students investigate how different riparian ground covers, such as grass and 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 riverbed. 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.

The lesson introduces students to the steps of the water cycle and rivers. They think about the effects of communities, sidewalks and roads on the natural flow of rainwater. Students also learn about the role of engineering in community planning and protecting our natural resources.

Students learn how water is used to generate electricity. They investigate water's potential-to-kinetic energy transformation in hands-on activities about falling water and waterwheels. During the activities, they take measurements, calculate averages and graph results. Students also learn the history of the waterwheel and how engineers use water turbines in hydroelectric power plants today. They discover the advantages and disadvantages of hydroelectric power. In a literacy activity, students learn and write about an innovative new hydro-electrical power generation technology.

In this lesson, students learn about major landforms (e.g., mountains, rivers, plains, valleys, canyons and plateaus) and how they occur on the Earth's surface. They learn about the civil and geotechnical engineering applications of geology and landforms, including the design of transportation systems, mining, mapping and measuring natural hazards.
