Students will examine and understand the potential of online collective fundraising (e.g. Kickstarter, GoFundMe, IdieGoGo) and it’s potential impact on alternative sources of energy (Gravity, Electricity, Wind Energy). The example that I will show them is called the Gravity Light. It uses the principle of conservation of energy to convert gravitational potential energy into kinetic energy and then into electrical energy. Students will then do some research on Kickstarter, Indiegogo, and/or GoFundMe to find an alternative source of energy that is in development and awaiting funding. Students will look at areas including potential impact to the environment, potential impact to the economy, barriers to success, alternative ideas that they have thought of because of doing this research, amount of money that can be made from this project, etc.

Students learn about power generation using river currents. A white paper is a focused analysis often used to describe how a technology solves a problem. In this literacy activity, students write a simplified version of a white paper on an alternative electrical power generation technology. In the process, they develop their critical thinking skills and become aware of the challenge and promise of technological innovation that engineers help to make possible. This activity is geared towards fifth grade and older students and computer capabilities are required. Some portions of the activity may be appropriate with younger students. CAPTION: Upper Left: Trey Taylor, President of Verdant Power, talks about green power with a New York City sixth-grade class. Lower Left: Verdant Power logo. Center: Verdant Power's turbine evaluation vessel in New York's East River. In the background is a conventional power plant. Upper Right: The propeller-like turbine can be raised and lowered from the platform of the turbine evaluation vessel. Lower Right: Near the East River, Mr. Taylor explains to the class how water currents can generate electric power.

Students learn about the wonderful and fascinating country of China, and its environmental challenges that require engineering solutions, many in the form of increased energy efficiency, the incorporation of renewable energy, and new engineering developments for urban and rural areas. China is fast becoming an extremely influential factor in our world today, and will likely have a large role in shaping the decades ahead. China is the world's largest energy consumer and the largest producer of carbon dioxide emissions, leading engineers and scientists to be concerned about the role these emissions play in rural and urban public and environmental health, as well as in global climate change. Through exploring some sources of air pollution, appropriate housing for different climate zones, and the types of renewable energy, the lessons and activities of this unit present ways that engineers are helping people in China, using an approach to cleaner, smarter, healthier and more-efficient ways of living that apply to people wherever they live.
Students form expert engineering teams working for the (fictional) alternative energy consulting …
Students form expert engineering teams working for the (fictional) alternative energy consulting firm, Greenewables, Inc. Each team specializes in a form of renewable energy used to generate electrical power: passive solar, solar photovoltaic, wind power, low-impact hydropower, biomass, geothermal and (for more advanced students) hydrogen fuel cells. Teams produce poster presentations making a case for their technology and produce an accompanying PDF document using Adobe Acrobat that summarizes the presentation. This activity is geared towards fifth-grade and older students, and Internet research capabilities are required. Some portions of this activity may be appropriate with younger students.

The class forms a "Presidential Task Force" for a week, empowered by the president to find answers and make recommendations concerning the future of the national power grid. Task force members conduct daily debriefings with their research team and prepare a report and presentation of their findings for the president, using an actual policy document as a guide. Although this activity is geared towards fifth-grade and older students and Internet research capabilities are required, some portions may be appropriate for younger students.

This lab exercise exposes students to a potentially new alternative energy source hydrogen gas. Student teams are given a hydrogen generator and an oxygen generator. They balance the chemical equation for the combustion of hydrogen gas in the presence of oxygen. Then they analyze what the equation really means. Two hypotheses are given, based on what one might predict upon analyzing the chemical equation. Once students have thought about the process, they are walked through the experiment and shown how to collect the gas in different ratios. By trial and error, students determine the ideal combustion ratio. For both volume of explosion and kick generated by explosion, they qualitatively record results on a 0-4 scale. Then, students evaluate their collected results to see if the hypotheses were correct and how their results match the theoretical equation. Students learn that while hydrogen will most commonly be used for fuel cells (no combustion situation), it has been used in rocket engines (for which a tremendous combustion occurs).
Students read and evaluate descriptions of how people live "off the grid" …
Students read and evaluate descriptions of how people live "off the grid" using solar power and come to understand better the degree to which that lifestyle is or is not truly independent of technological, economic and cultural infrastructure and resources. In the process, students develop a deeper appreciation of the meaning of "community" and the need for human connection. This activity is geared towards fifth-grade and older students and Internet research capabilities are required. Portions of this activity may be appropriate with younger students.
