"Green" jobs that contribute to preserving the environment are among the fastest-growing careers in the U.S., according to the Bureau of Labor Statistics. With the rising need for workers to fill these positions, and surging interest among students in environmental careers, community colleges are creating new courses, certifications and…

BLACKOUT! is a turn-based video game that introduces undergraduate and high school students to the types of power generation available in most electricity markets. The workshop portion of BLACKOUT! introduces students to the advantages and disadvantages of power generation by coal, natural gas, nuclear, wind and solar. The students then take the…

Over the past 10 years, Turtle Mountain Community College (TMCC) in Belcourt, North Dakota, has developed a formula for sustainable infrastructure development. The college does not take natural resources, use them, and then dump chemicals, carbon monoxide, or other toxic waste back into the ecosystem. Instead, the college has invested in…

Universities have always been acknowledged as important drivers of economic development. Traditionally Institutions of Higher Education (IHEs) contributed indirectly by disseminating knowledge and providing educated personnel to industries. A shift in the primary missions of universities encourages universities to take a more active role in…

Charging a capacitor with a photovoltaic module is an experiment which reveals a lot about the modules characteristics. It is customary to represent these characteristics with an equivalent circuit whose elements represent its physical parameters. The behavior of a photovoltaic module is very similar to that of a single cell but the electric…

Earth wires and fuses work together in UK mains circuits to keep users safe from electric shocks and are taught in many school contexts. The subject can be quite abstract and difficult for pupils to grasp, and a simple but visually clear and direct demonstration is described which would be easy for most physics departments to build and which can…

The classroom jumping ring demonstration is nearly always performed using alternating current (AC), in which the ring jumps or flies off the extended iron core when the switch is closed. The ring jumps higher when cooled with liquid nitrogen (LN2). We have performed experiments using DC to power the solenoid and find similarities and significant…

In this article Dave Vernier describes how he turned the total eclipse on August 21, 2017 into a science, technology, engineering and mathematics (STEM) lesson by taking data. He asked teachers and former teachers to join in collecting data and to share it. The most frequently monitored parameters were illuminance (a measure of light brightness as…

For an electrical engineer, training of power system configuration and operation is an essential problem. This paper proposes new training device which consists of separated circuit blocks (module). For example, induction generator, inverter, capacitor, measurement, are used. The trainee selects and assembles them to build a circuit then easy to…

The 1990 film "The Hunt for Red October" (based on Tom Clancy's 1984 debut novel of the same name) featured actors like Sean Connery and Alec Baldwin, but the star of the movie for physicists was a revolutionary new magnetohydrodynamic (MHD) marine propulsion system. The so-called "caterpillar drive" worked with no moving…

A remote-controlled experiment for power electronics was developed for a virtual laboratory. Power converter experiments were set up, allowing students to conduct a remote-controlled experiment with special hardware and electric power. Students can activate parameter controls, connect wires, and tune electric load conditions with preset electronic…

The design and fabrication of functional scientific instrumentation allows students to forge a link between commonly reported numbers and physical material properties. Here, a two-point and four-point probe station for measuring electrical properties of solid materials is fabricated via 3D printing utilizing an inexpensive benchtop…

Educating our future citizens in science and engineering is vitally important to ensure future advancement. Presently, in the light of environmental sustainability, it is critical that students learn concepts relating to energy, its consumption and future demands. In this article, we harness the state of the educational technology, namely…

When all parts of an electric circuit are at the same potential, no electric current flows and it is said to be in "equilibrium." Otherwise, a current will flow from the higher potential parts to the lower ones, as when we make contact between the plates of a charged capacitor. The resulting discharging process towards equilibrium is a…

We are hereby presenting a didactic concept for an advanced lab course that focuses on the design of donor materials for organic solar cells. Its research-related and competence-based approach qualifies the students to independently and creatively apply computational methods and to profoundly and critically discuss the results obtained. The high…
