Students learn about the importance of dams by watching a video that presents historical and current information on dams, as well as descriptions of global water resources and the hydrologic cycle. Students also learn about different types of dams, all designed to resist the forces on dams. (If the free, 15-minute "Water and Dams in Today's World" video cannot be obtained in time, the lesson can still be taught. See the Additional Multimedia Support section for how to obtain the DVD or VHS videotape, or a PowerPoint presentation with similar content [also attached].)

WOW lessons are designed for infusion into the existing science curriculums for college freshmen and advanced high school students. The lessons use the aquatic environment and real lake data to explore basic science concepts through two different approaches: a directed study “Studying” and an inquiry “Investigating” approach. The directed studies allow students to apply and learn concepts through direct, guided experience. The inquiry lessons provide a more open-ended opportunity for students to discover the same concepts.
Each teacher's lesson plan provides general direction for guiding students to understand the topic through the directed study and the inquiry approach. Student lessons are organized into a thinking framework of six sequential components that are critical for improving scientific and technological literacy: knowledge base, experimental design, data collection, data management and analysis, interpretation of results, and reporting results. The teacher lesson plans follow the same format.
Lesson titles are simple and descriptive so that you may easily find useful materials. We recommend you begin by reviewing the student lessons that may be appropriate for your class. When you've found a student lesson to use, return to the menu below to review the associated teacher's lesson plan. There are tutorials to help you and your students get familiar with the site, they may be accessed from the menu below, or at the top of any 'teacher' page.

Students learn about the water cycle and its key components. First, they learn about the concept of a watershed and why it is important in the context of engineering hydrology. Then they learn how we can use the theory of conservation of mass to estimate the amount of water that enters a watershed (precipitation, groundwater flowing in) and exits a watershed (evaporation, runoff, groundwater out). Finally, students learn about runoff and how we visualize runoff in the form of hydrographs.

Students build a model of a watershed, apply water to the model, and explore what happens when elements of the watershed are changed.

In this scenario-based activity, students design ways to either clean a water source or find a new water source, depending on given hypothetical family scenarios. They act as engineers to draw and write about what they could do to provide water to a community facing a water crisis. They also learn the basic steps of the engineering design process.

Students will test the percolation rates of 6 different soil samples. Three of the samples are measured sand and clay and three are collected from the schoolyard and wetland.

In this activity, students act as water molecules and travel through parts of the water cycle (ocean, atmosphere, clouds, glaciers, snow, rivers, lakes, ground, aquifer). Students use a diagram of the hydrologic cycle to draw the pathway they traveled.

In this activity students build a model of a watershed to learn where water goes when it rains. Students then make predictions and draw what they observe.

Students learn about the Earth's water cycle, especially about evaporation. Once a dam is constructed, its reservoir becomes a part of the region's natural hydrologic cycle by receiving precipitation, storing runoff water and evaporating water. Although almost impossible to see, and not as familiar to most people as precipitation, evaporation plays a critical role in the hydrologic cycle, and is especially of interest to engineers designing new dams and reservoirs, such as those that Splash Engineering is designing for Thirsty County.

This short demonstration will open students' eyes to the distribution of various water sources on our Earth, but also the limited amount of fresh water for our daily use.

In this video segment from Planet H20: Water World, experts and teens inside and outside the Great Lakes watershed provide different perspectives on sharing the water from one of the largest bodies of fresh water in the world.

In this video segment adapted from United Tribes Technical College, listen as six Native American students share their concerns, hopes, and knowledge about climate change.
