El desperdicio de comida es uno de los principales contribuyentes a los gases de efecto invernadero. Los alimentos desperdiciados y los recursos para producirlos son responsables de aproximadamente el 8% de las emisiones mundiales de gases de efecto invernadero. En este caso, los estudiantes aprenden sobre los recursos necesarios para producir alimentos a través del ciclo del carbono y descubren cómo el desperdicio de alimentos contribuye al cambio climático. También aprenderán la cadena de transporte de la granja a la mesa y cómo llevar a cabo una evaluación de desperdicio de comida. Finalmente, los estudiantes investigarán soluciones al problema del desperdicio de comida y, como proyecto final, presentarán una solución que han investigado a fondo que puede ser aplicable a su comunidad. Para los maestros de CTE, este caso proporciona el conocimiento básico necesario para desarrollar una comprensión profunda de POR QUÉ reducir el desperdicio de comida es una solución importante para el cambio climático. Hay varias extensiones potenciales que los maestros de ciencias del consumo familiar pueden utilizar, así como los maestros de Agricultura e incluso los maestros de Negocios. Hay una lista parcial al final de las progresiones de aprendizaje.

Solar energy in the form of light is available to organisms on Earth in abundance. Natural systems and other organisms have structures that function in ways to manage the interaction with and use of this energy. Using these natural examples, humans have (in the past) and continue to design and construct homes which manage solar energy in passive and active ways to reduce the need for energy from other sources. In this storyline, students will explore passive and active solar energy management through examples in the natural world. Students will use knowledge gained to design a building that maximizes the free and abundant energy gifts of the sun.

This is a solutions-oriented storyline that leads students through a series of investigations to quantify and qualify the ecosystem and social benefits of an urban forest. At the end of the storyline, students will be able to design, evaluate and refine a chosen solution for urban forest ecosystem benefits.

Students will engage in learning about the function and benefits of coastal wetlands and their role in adapting and mitigating rising carbon levels and sea level rise. Spatial and interactive planning tools will support students in collaboratively designing solutions to enhance coastal wetlands.

This activity focuses on applying analytic tools such as pie charts and bar graphs to gain a better understanding of practical energy use issues. It also provides experience with how different types of data collected affect the outcome of statistical visualization tools.

This small-group activity uses engineering concepts to design energy systems for three off-the-grid towns in Mali, Ethiopia, and Namibia.

Acting as civil engineers hired by the U.S. Department of Transportation to research how to best use piezoelectric materials to detect road damage, student groups are challenged to independently create their own experiment procedures, working with given materials and tools. The general approach is that they set up model roads using rubber mats to simulate asphalt and piezoelectric transducers to simulate the in-ground road sensors. They drop heavy bolts at various locations on the “road,” collecting data and then analyzing the voltage changes across the piezoelectric transducers caused by the vibrations of the bolt hitting the rubber. After making notches in the rubber “road” to simulate cracks and potholes, they collect more data to see if the piezo elements detect the damage. Students write up their research and conclusions as if presenting evidence to USDOT officials about how the voltage changes across the piezo elements can be used to indicate road damage and extrapolated to determine when roads need maintenance service.

Pumps are used to get drinking water to our houses every day! And in disaster situations, pumps are essential to keep flood water out. In this hands-on activity, student groups design, build, test and improve devices to pump water as if they were engineers helping a rural village meet their drinking water supply. Students keep track of their materials costs, and calculate power and cost efficiencies of the prototype pumps. They also learn about different types of pumps, how they work and useful applications.

Students become familiar with the online Renewable Energy Living Lab interface and access its real-world solar energy data to evaluate the potential for solar generation in various U.S. locations. They become familiar with where the most common sources of renewable energy are distributed across the U.S. Through this activity, students and teachers gain familiarity with the living lab's GIS graphic interface and query functions, and are exposed to the available data in renewable energy databases, learning how to query to find specific information for specific purposes. The activity is intended as a "training" activity prior to conducting activities such as The Bright Idea activity, which includes a definitive and extensive end product (a feasibility plan) for students to create.

In this eight-lesson unit, students explore cultural connections with the sun, learn about light and discover how light interacts with other materials through hands-on activities, literacy integration, and engineering.

Over several days, students learn about composites, including carbon-fiber-reinforced polymers, and their applications in modern life. This prepares students to be able to put data from an associated statistical analysis activity into context as they conduct meticulous statistical analyses to evaluate/determine the effectiveness of carbon fiber patches to repair steel. This lesson and its associated activity are suitable for use during the last six weeks of an AP Statistics course; see the topics and timing note for details. A PowerPoint® presentation and post-quiz are provided.

Student pairs reverse engineer objects of their choice, learning what it takes to be an engineer. Groups each make a proposal, create a team work contract, use tools to disassemble a device, and sketch and document their full understanding of how it works. They compile what they learned into a manual and write-up that summarizes the object's purpose, bill of materials and operation procedure with orthographic and isometric sketches. Then they apply some of the steps of the engineering design process to come up with ideas for how the product or device could be improved for the benefit of the end user, manufacturer and/or environment. They describe and sketch their ideas for re-imagined designs (no prototyping or testing is done). To conclude, teams compile full reports and then recap their reverse engineering projects and investigation discoveries in brief class presentations. A PowerPoint(TM) presentation, written report and oral presentation rubrics, and peer evaluation form are provided.

Warming oceans and melting landlocked ice caused by global climate change may result in rising sea levels. This rise in sea level combined with increased intensity and frequency of storms will produce storm surges that flood subways, highways, homes, and more. In this activity, visitors design and test adaptations to prepare for flooding caused by sea level rise.

This role-playing activity allows students to learn more about the six general ways Americans respond to climate change and engage in conversations while embodying these groups. Students will be able to describe the different ways Americans respond to climate change and develop arguments to support their claims.

Through this activity, students come to understand the environmental design considerations required when generating electricity. The electric power that we use every day at home and work is usually generated by a variety of power plants. Power plants are engineered to utilize the conversion of one form of energy to another. The main components of a power plant are an input source of energy that is used to turn large turbines, and a method to convert the turbine rotation into electricity. The input sources of energy include fossil fuels (coal, natural gas and oil), wind, water, nuclear materials and refuse. This activity focuses on how much energy can be converted to electricity from many of these input sources. It also considers the impact of the by-products associated with using these natural resources, and looks at electricity requirements. To do this, students research and evaluate the electricity needs of their community, the available local resources for generating electricity, and the impact of using those resources.

In this hands-on activity, students explore whether rooftop gardens are a viable option for combating the urban heat island effect. The guiding question is: Can rooftop gardens reduce the temperature inside and outside of houses?

Student teams practice water quality analysis through turbidity measurement and coliform bacteria counts. They use information about water treatment processes to design prototype small-scale water treatment systems and test the influent (incoming) and effluent (outgoing) water to assess how well their prototypes produce safe water to prevent water-borne illnesses.

This activity features video segments from a 2007 PBS program on solar energy. Students follow a seven-step invention process to design, build, and test a solar cooker that will pasteurize water.
