Students use a small stream table in groups to investigate how channel form determines the shape of the hydrograph (including lag to peak). They use three channels: no channel (just sediment filling the table), a "concrete" channel (straight, no sediment on bottom), and a meandering channel. All channels get the same water input and students measure the amount of water that comes out to make a hydrograph. This gives students a chance to model a flood pulse moving through different channels to see how anthropogenic changes to rivers, such as channelizing them, alters flood hydrology. It specifically models an outburst flood from a dam release or burst, but is basically modeling any pulse of water moving through a system.

Stratified lakes exhibit vertical gradients in organisms, nutrients, and oxygen, which have important implications for ecosystem structure and functioning. Mixing disrupts these gradients by redistributing these materials throughout the water column. Consequently, it is critical to understand the drivers of lake mixing and thermal stratification, especially because of the sensitivity of lake thermal conditions to altered climate. In this module, students will explore spatial and temporal patterns of lake mixing using high-frequency temperature data from lakes around the world. They will also explore how increases in air temperature affect thermal stratification by interpreting output from a lake model. Project EDDIE modules are designed with an A-B-C structure to make them flexible and adaptable to a range of student levels and course structures.

This lesson helps students understand why Earth is considered the "water planet." Students analyze how much of Earth's water is available for humans to use for life-sustaining purposes, and they explore the concept of water scarcity in both physical and economic terms. They look at the many ways that humans use water and investigate international trends in agricultural, industrial, and household water consumption. The lesson also sets up the focus of this course: the concept of water footprints. Students explore how water footprints are an invaluable tool for identifying patterns of water use so that individuals, businesses, and even nations can more effectively manage their use of one of the most precious resources on Earth: water. Critical to this exploration is a visit to Watercalculator.org, where students calculate their personal water usage, analyze the results, and set a base point for tracking and conserving their water use.

This is the first of the three-part Lessons for Understanding Our Water Footprint: High School Lesson Plans.

This lesson centers on a deeper exploration of the water footprint associated with food. Students learned in Lesson 1 that virtual water, especially as it relates to food, typically makes up the majority of their water footprint. In this lesson, they find out why. First, they see an attention-grabbing demonstration of how much water is needed for three food products. Second, they break into groups to do research, and then they teach their classmates about key aspects of water use related to food and agriculture. Next, they think about how their diet is influenced by social groups, advertising, and structures in place at home and at school that encourage them to potentially eat food with large water footprints. Finally, they brainstorm ways they might be able to influence change in those areas. The lesson concludes with students sharing their ideas and providing one another with constructive feedback.

Session 1 of this lesson begins with a quick activity to get students thinking about their direct and virtual water use. It introduces a few new ideas for virtual water use that may surprise students, including the virtual water required for the products we buy and use. Then students form marketing teams to explore five categories of water use (indoor, outdoor, diet, electricity, and buying habits) and create infographic posters to share what they learn. Then, in Session 2, students remain in five teams to audit the school's indoor and outdoor direct water use as well as several categories of virtual water use: food, energy, and electronics. They use what they learn to create a strategic conservation action plan that incorporates their How to Save Water awareness campaign in an effort to decrease the school's overall virtual water use. The lesson can be conducted as a short project or a more comprehensive capstone project.

The Lifestyle Project is a way for students to learn about environmental alternatives by modifying their own lifestyles. It is a three-week exercise for students to reduce their impact on the environment by changing the way in which they live from day to day. The project has fairly rigid parameters, allowing students to achieve a gradual but definitive change in their everyday habits. Students choose three categories from a list of six: heat, garbage, electricity and water, driving, eating, and activism. For each category the rules are clearly defined, such as turning down the heat three degrees or eliminating the use of the car. Each week the project becomes more rigorous, because students will have to meet the requirements more frequently. They write about their experiences in journals, which are incredibly insightful, illustrating just how profoundly the project affects them.

The project is used in two courses, both with the theme of understanding the environmental implications of our use of energy, exploring personal energy use, and learning about the types of energy available to Canadians. One is a face-to-face course for Education majors, the other is an on-line course available to all upper-level (3rd and 4th year) students.

I use the Lifestyle Project in my Introduction to Environmental Issues class. This 3-week project asks students to make changes to their everyday environmental habits. This helps students realize that they have control of their lives and they can make decisions and make changes if they want to. And, given this empowerment, students can think about their impacts on Earth and their obligations to the planet and our society.

This three-week project begins with a measurement of "baseline" consumptive behavior followed by two weeks of working to reduce the use of water, energy, high-impact foods, and other materials. The assignment uses an Excel spreadsheet that calculates direct energy and water use as well as indirect CO2 and water use associated with food consumption.

Students are introduced to the structure, function and purpose of locks and dams, which involves an introduction to Pascal's law, water pressure and gravity.

In this lab students will explore first hand what sorts of processes occur when scientists and engineers try to identify a landing site for a mission to Mars. This will mimic the process used to select the MER rover landing sites, and what will be used for future missions. First, students briefly become a planetary geologist, engineer or astrobiologist. Second, from the point of view the students feel is appropriate for their new position, and using the same constraints employed by the scientific teams preparing for forthcoming Mars missions, students will identify their top list of candidate landing sites and submit a short report describing them to me by the following class period. Third, in the following class period, all three groups of experts will work together to narrow down the site selection to a top candidate. Where would you send the next lander if the choice was up to you?
Each student group, constituted randomly, is provided with the appropriate role-playing sheet from the lab assignment.

Dissolved ions are present in all freshwater systems, but humans can change the chemical composition of freshwater in several ways. In this activity, students will examine the concentration of major ions in freshwater systems over time and reason about potential drivers of these changes.
