In this activity, the students will complete the grand challenge and design an electromagnet to separate steel from aluminum for the recycler. In order to do this, students compare the induced magnetic field of an electric current with...

This lesson begins with a demonstration of the deflection of an electron beam. Learners then review their knowledge of the cross product and the right hand rule with sample problems. After which, students study the magnetic force on a...

The Scottish instrument maker and inventor James Watt had a tremendous impact on the shape of modern society. His improvements to the steam engine were a significant factor in the Industrial Revolution, and when the Watt engine was...

We solve a circuit by direct application of the fundamental laws: Apply element laws (Ohm's Law and the like) plus Kirchhoff's Laws to solve for the currents and voltages of a circuit.

A place to share and see others' ideas for improving a lego robotics project, light guitar.

In 1866, the research of Werner von Siemens would lead to his discovery of the dynamo electric principle that paved the way for the large-scale generation of electricity through mechanical means.

College-level electrical engineering and computer science textbook highlighting the applications of continuum electromechanics.

This extension to the Ohm's Law I activity, students will observe just how much time it takes to use up the "juice" in a battery, and if it is better to use batteries in series or parallel.

Students design and build a working robotic arm from a set of everyday items with a goal of having the arm be able to pick up a Styrofoam cup. Working in teams of three or four students, the students explore effective teamwork skills...

Students evaluate various everyday energy conversion devices and draw block flow diagrams to show the forms and states of energy into and out of the device. They also identify the forms of energy that are useful and the desired output of...

A design challenge through which learners design and construct a solar-powered model car to compete in a road race. Students work in teams using the engineering design process to select the optimal gear ratio and components.

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...

Humans need food, water, and warm shelter to survive. But a lot of humans depend on fossil fuels to supply gas and electricity to heat our homes. But burning fossil fuels to create energy is harmful to the environment. In this science...

Using plastic straws, wire, batteries and iron nails, student teams build and test two versions of electromagnets-one with and one without an iron nail at its core. They test each magnet's ability pick up loose staples, which reveals the...

Young scholars learn how the total solar irradiance hitting a photovoltaic (PV) panel can be increased through the use of a concentrating device, such as a reflector or lens. This is the final lesson in the Photovoltaic Efficiency unit...

This activity simulates the extraction of limited, nonrenewable resources from a "mine," so students can experience first-hand how resource extraction becomes more difficult over time. Students gather data and graph their results to...

Spanish-language site lets students discover the life and work of this physicist and engineer, who is known for his studies of electric charges.

Discusses the development of a new rocket engine that operates by the ion propulsion as opposed to gas propulsion. Well written and great graphics!

A instructional activity for students to explore the conversion of energy from electrical energy to kinetic energy by constructing a homopolar motor. Also by constructing the motor, students can investigate magnetism, electricity, and RPM.

Find out about the event and societal needs lead to the invention of superconductors.

This activity will have students creating their own speaker with a paper cup, coil of wire, and magnet. The speaker operates by changing electric current into sound.
