In this unit, students explore the various roles of environmental engineers, including: environmental cleanup, water quality, groundwater resources, surface water and groundwater flow, water contamination, waste disposal and air pollution. Specifically, students learn about the factors that affect water quality and the conditions that enable different animals and plants to survive in their environments. Next, students learn about groundwater and how environmental engineers study groundwater to predict the distribution of surface pollution. Students also learn how water flows through the ground, what an aquifer is and what soil properties are used to predict groundwater flow. Additionally, students discover that the water they drink everyday comes from many different sources, including surface water and groundwater. They investigate possible scenarios of drinking water contamination and how contaminants can negatively affect the organisms that come in contact with them. Students learn about the three most common methods of waste disposal and how environmental engineers continue to develop technologies to dispose of trash. Lastly, students learn what causes air pollution and how to investigate the different pollutants that exist, such as toxic gases and particulate matter. Also, they investigate the technologies developed by engineers to reduce air pollution.

Students are introduced to the fundamentals of environmental engineering as well as the global air, land and water quality concerns facing today's environmental engineers. After a lesson and activity to introduce environmental engineering, students learn more about water chemistry aspects of environmental engineering. Specifically, they focus on groundwater contamination and remediation, including sources of contamination, adverse health effects of contaminated drinking water, and current and new remediation techniques. Several lab activities provide hands-on experiences with topics relevant to environmental engineering concerns and technologies, including removal efficiencies of activated carbon in water filtration, measuring pH, chromatography as a physical separation method, density and miscibility.

Students explore material properties in hands-on and visually evident ways via the Archimedes' principle. First, they design and conduct an experiment to calculate densities of various materials and present their findings to the class. Using this information, they identify an unknown material based on its density. Then, groups explore buoyant forces. They measure displacement needed for various materials to float on water and construct the equation for buoyancy. Using this equation, they calculate the numerical solution for a boat hull using given design parameters.

Students observe multiple examples of capillary action. First they observe the shape of a glass-water meniscus and explain its shape in terms of the adhesive attraction of the water to the glass. Then they study capillary tubes and observe water climbing due to capillary action in the glass tubes. Finally, students experience a real-world application of capillary action by designing and using "capillary siphons" to filter water.

Context:The teachers facilitate an author study every year among our K-2 unit. This year, we wanted to focus on local authors who have written picture books that address both cultural and environmental literacy. The books included in this unit by Miranda and Baptiste Paul. These texts teach about the water cycle, the life cycle of plants, how our environment impacts our recreation, and how individuals can rally their communities to make improvements in their environment.  understanding.About the author: Ned Dorff has been teaching for 20 years. He has taught regular, gifted, special, and alternative education classes. Ned holds a master’s degree in Environmental Education from the University of Wisconsin-Stevens Point.

On Day 1, students will explore groundwater and how the depletion of groundwater can cause land subsidence in regions like California’s Central Valley. Students will also learn about how agricultural water use for different crops compares to the amount of water required for raising animals on farms and ranches.

On Day 2, students will read some of the Blue Planet Network’s Stories of Water to learn about how different people around the world struggle to have access to clean water and some of the ways they have addressed this issue. They will also explore their own water use habits and ways they can reduce water waste in their home using a water calculator from the Alliance for Water Efficiency and a leaky faucet calculator from the U.S. Geological Survey’s Water Science School.

Students test and observe the "self-cleaning" lotus effect using a lotus leaf and cloth treated with a synthetic lotus-like superhydrophobic coating. They also observe the Wenzel and Cassie Baxter wetting states by creating and manipulating condensation droplets on the leaf surface. They consider the real-life engineering applications for these amazing water-repellent and self-cleaning properties.

Students conduct experiments to determine the flow rate of faucets by timing how long it takes to fill gallon jugs. They do this for three different faucet flow levels (quarter blast, half blast, full blast), averaging three trials for each level. They convert their results from gallons per second (gps) to cubic feet per second (cfs).

Students further their understanding of the salmon life cycle and the human structures and actions that aid in the migration of fish around hydroelectric dams by playing an animated PowerPoint game involving a fish that must climb a fish ladder to get over a dam. They first brainstorm their own ideas, and then learn about existing ways engineers have made dams "friendlier" to migrating fish, before being quizzed as part of the game.

Fish Species Commercially Harvested or Raised in Wisconsin for Food
Common names for fish can be different by region.

Students experience firsthand one of the most common water treatment types in the industry today, flocculants. They learn how the amount of suspended solids in water is measured using the basic properties of matter and light. In addition, they learn about the types of solids that can be found in water and the reasons that some are easier to remove than others. Encompassing the concepts of force and motion, attraction and repulsion of charged particles, and properties of matter, during the associated activity students see scientific concepts they already understand through the eyes of engineers who apply them to the removal of solids from water via chemical flocculants.

Students learn how to use and graph real-world stream gage data to create event and annual hydrographs and calculate flood frequency statistics. Using an Excel spreadsheet of real-world event, annual and peak streamflow data, they manipulate the data (converting units, sorting, ranking, plotting), solve problems using equations, and calculate return periods and probabilities. Prompted by worksheet questions, they analyze the runoff data as engineers would. Students learn how hydrographs help engineers make decisions and recommendations to community stakeholders concerning water resources and flooding.

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 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.

In the Flow Rate Experiment, students perform hands-on experiments with a common faucet, as well as work with the Engineering Our Water Living Lab to gain a better understanding of flow rate and how it pertains to engineering and applied science. Students calculate the flow rate of a faucet for three different levels (quarter blast, half blast, and full blast). Building on these calculations, students hypothesize about the flow rate in a nearby river, and then use the Engineering Our Water Living Lab to check their hypothesis. For this lesson to be effective, your students need to have a visual feel for the flow in a nearby river.

Explore pressure in the atmosphere and underwater. Reshape a pipe to see how it changes fluid flow speed. Experiment with a leaky water tower to see how the height and water level determine the water trajectory.

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.

In this activity, students will use a tutorial on the U.S. Environmental Protection Agency's website to learn about how surface water is treated to make it safe to drink.
