Waterwheels are devices that generate power and do work. Student teams construct waterwheels using two-liter plastic bottles, dowel rods and index cards, and calculate the power created and work done by them.

Students learn how engineers design devices that use water to generate electricity by building model water turbines and measuring the resulting current produced in a motor. Student teams work through the engineering design process to build the turbines, analyze the performance of their turbines and make calculations to determine the most suitable locations to build dams.

Students learn how engineers harness the energy of the wind to produce power by following the engineering design process as they prototype two types of wind turbines and test to see which works best. Students also learn how engineers decide where to place wind turbines, and the advantages and disadvantages to using wind power compared to other non-renewable energy sources.

This course provides understanding of the theory and processes of negotiation as practiced in a variety of settings. It is designed for relevance to the broad spectrum of bargaining problems faced by the manager and professional. With an emphasis on simulations, exercises, role playing and cases, students are given an opportunity to develop negotiation skills experientially and to understand negotiation in useful analytical frameworks.

Working in groups, students look at three different villages in various parts of Africa and design economically viable engineering solutions to answer the energy needs of the off-the-grid small towns, given limited budgets. Each village has different nearby resources, both renewable and nonrenewable. Student teams conduct research, make calculations, consider the options and create plans, which they present to the class. Through their investigations and planning of custom solutions for each locale, they experience the real-world engineering research and analysis steps of the engineering design process.

Students continue to explore the story of building a pyramid, learning about the simple machine called a pulley. They learn how a pulley can be used to change the direction of applied forces and move/lift extremely heavy objects, and the powerful mechanical advantages of using a multiple-pulley system. Students perform a simple demonstration to see the mechanical advantage of using a pulley, and they identify modern day engineering applications of pulleys. In a hands-on activity, they see how a pulley can change the direction of a force, the difference between fixed and movable pulleys, and the mechanical advantage gained with multiple / combined pulleys. They also learn the many ways engineers use pulleys for everyday purposes.

In this activity, students act as power engineers by specifying the power plants to build for a community. They are given a budget, an expected power demand from the community, and different power plant options with corresponding environmental effects. They can work through this scenario as a class or on their own.

This lesson provides students with an overview of the electric power industry in the United States. Students also become familiar with the environmental impacts associated with a variety of energy sources.

Our digital footprints can impact our future. What others find about us online shapes how they see us or feel about us. Help your students learn about their digital footprint and the steps they can take to shape what others find and see about them online.

In this lesson, through various examples and activities, exponential growth and polynomial growth are compared to develop an insight about how quickly the number can grow or decay in exponentials. A basic knowledge of scientific notation, plotting graphs and finding intersection of two functions is assumed.

Students imagine they are stranded on an island and must create the brightest light possible with the meager supplies they have on hand in order to gain the attention of a rescue airplane. In small groups, students create circuits using items in their "survival kits" to create maximum voltage, measured with a multimeter and two LED lights. To complete the activity, students act as engineers by using the given materials to create circuits that produces the highest voltage and light up the most LED lights. They apply their knowledge of how voltage differs in a series circuit and a parallel circuit to design their solutions.

Students learn about the mechanical advantage offered by pulleys in an interactive and game-like manner. By virtue of the activity's mechatronic presentation, they learn to study a mechanical system not as a static image, but rather as a dynamic system that is under their control. Using a LEGO® MINDSTORMS® robotics platform and common hardware items, students build a mechanized elevator system. The ability to control different parameters (such as motor power, testing load and pulley arrangement) enables the teacher, as well as the students, to emphasize and reinforce particular aspects/effects of mechanical advantage.

This workshop provides an introduction to urban environmental design and explores the potential of information technology and the Internet to transform public education, city design, and community development in inner-city neighborhoods. Integration of comprehensive ("top-down") and grassroots ("bottom-up") approaches to design and planning is a major theme.

As kids grow, they'll naturally start to communicate more online. But some of what they see could make them feel hurt, sad, angry, or even fearful. Help your students build empathy for others and learn strategies to use when confronted with cyberbullying.

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.

In 1607, a party of Englishmen landed in a place they called Virginia. They followed in the footsteps of Sir Walter Raleigh, who had visited Virginia (which, at the time, included North Carolina) with a party of settlers in 1585. The colony founded by Raleigh’s party failed, weakened by lack of supplies and irregular contact with England.

To the people who already lived in the area, this was the land of the Powhatan Confederacy, a vast regional network of allied communities living under the leadership of Wahunsenacah (also known as Powhatan). Contact between the English and the people of the Powhatan confederacy was fraught with misunderstanding and conflict. This owed a great deal to the fact that the English were in the Americas to form a colony and make money for the Virginia Company of London, the corporation that had launched them on their voyage west. The Powhatan, on the other hand, lived out their values of kinship, allyship, and reciprocity in a way that was at first incomprehensible to the English, and that later they firmly rejected.

This art history video discussion looks at Fra Andrea Pozzo's "Glorification of Saint Ignatius" ceiling fresco in the nave of Sant'Ignazio, Rome, 1691-1694.

This art history video discussion examines Andrea Pozzo's Saint Ignatius Chapel in the left transept of the church, Il Ges, Rome (commissioned in 1695). Many artists contributed including Alessandro Algardi, Pierre Legros, Bernardino Ludovisi, Il Lorenzone and Jean-Baptiste Theodon. Materials include bronze, gold, silver, and many semiprecious stones most notably lapis lazuli.

This is a peer-reviewed chapter in an open access book, A Fresh Look at Anxiety Disorders. This chapter provides an overview of complementary and alternative medicine (CAM) and its relevance in psychiatric practice. Four case studies are discussed in which practitioners were open to the use of CAM and collaborated successfully with parents of youth with anxiety disorders. Vitamin D, melatonin, acupuncture, acupressure and craniosacral therapy are the CAM discussed. The chapter is accurate, relevant and clear. It is extensively referenced, and is still relevant today even though more up-to-date literature reviews are available. It is a technical reading that is best suited to nurses, physicians, nutritionists, mental health workers and other allied health professionals at both the undergraduate and graduate level.
