Students use electricity every day. It is important to know how it works. Why does the light come on when they flip the switch? With a simple knowledge of circuits, students will understand how electrical energy moves from one place to another. Students will provide evidence to describe why the light bulb turned on, including the idea that energy can be transferred from place to place by electrical currents.

n 2021, the United States saw the addition of 851 new electric generating and storage units with at least 1 MW capacity, totaling 37,769 MW of new capacity. Wind and solar accounted for 79% of this new capacity, followed by natural gas (11%) and storage (9%).

Students are introduced to the concept of energy conversion, and how energy transfers from one form, place or object to another. They learn that energy transfers can take the form of force, electricity, light, heat and sound and are never without some energy "loss" during the process. Two real-world examples of engineered systems light bulbs and cars are examined in light of the law of conservation of energy to gain an understanding of their energy conversions and inefficiencies/losses. Students' eyes are opened to the examples of energy transfer going on around them every day. Includes two simple teacher demos using a tennis ball and ball bearings. A PowerPoint(TM) presentation and quizzes are provided.

Students are introduced to the definition of energy and the concepts of kinetic energy, potential energy, and energy transfer. This lesson is a broad overview of concepts that are taught in more detail in subsequent lessons and activities in this curricular unit. A PowerPoint(TM) presentation and pre/post quizzes are provided.

Using an Arduino microprocessor, students will build an automated fish food feeder so fish can be fed when no one is at school?

This project involves learning how to do simple wiring of an LED, a buzzer, and a servo (motor) to a simple-to-use Arduino microprocessor.

Play with a bar magnet and coils to learn about Faraday's law. Move a bar magnet near one or two coils to make a light bulb glow. View the magnetic field lines. A meter shows the direction and magnitude of the current. View the magnetic field lines or use a meter to show the direction and magnitude of the current. You can also play with electromagnets, generators and transformers!

In this book I've attempted an innovation in the order of topics for freshman E&M, the goal being to follow the logical sequence while also providing plenty of opportunities for relating abstract ideas to hands-on experience. The typical sequence starts by slogging through Coulomb's law, the electric field, and Gauss's law, none of which are well suited to practical exploration in the laboratory. In this book, each of the first 5 chapters is short and includes a laboratory exercise that can be completed in about an hour and a half. The approach I've taken is to introduce the electric and magnetic field on an equal footing (which is in fact the way the subject was developed historically). As empirically motivated postulates, we take some primitive ideas about relativity along with the expressions for the energy and momentum density of the fields.

Another goal is to introduce the laws of physics in their natural, local form, i.e., Maxwell's equations in differential rather than integral form, without getting bogged down in an extensive development of the toolbox of vector calculus that would be more appropriate in an honors text like Purcell. Much of the necessary apparatus of div, grad, and curl is developed first in visual or qualitative form.

This is a continuation of Fundamentals of Physics, I (PHYS 200), the introductory course on the principles and methods of physics for students who have good preparation in physics and mathematics. This course covers electricity, magnetism, optics and quantum mechanics.

Generate electricity with a bar magnet! Discover the physics behind the phenomena by exploring magnets and how you can use them to make a bulb light.

Students are given a history of electricity and its development into the modern age lifeline upon which we so depend. The methods of power generation are introduced, and further discussion of each technology's pros and cons follows.

Students are introduced to the idea of electrical energy. They learn about the relationships between charge, voltage, current and resistance. They discover that electrical energy is the form of energy that powers most of their household appliances and toys. In the associated activities, students learn how a circuit works and test materials to see if they conduct electricity. Building upon a general understanding of electrical energy, they design their own potato power experiment. In two literacy activities, students learn about the electrical power grid and blackouts.

This activity is a lab where the students try to make a lightbulb light up using two wires, a battery and a lightbulb.

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 importance of an iron core to the magnet's strength. Students also learn about the prevalence and importance of electromagnets in their everyday lives.

Students gain an understanding of the difference between electrical conductors and insulators, and experience recognizing a conductor by its material properties. In a hands-on activity, students build a conductivity tester to determine whether different objects are conductors or insulators. In another activity, students use their understanding of electrical properties to choose appropriate materials to design and build their own basic circuit switch.

The grid delivers electricity from generation points to demand centers. Supply and demand of electricity must be balanced in real-time to ensure system stability and reliability. The electric grid is a natural monopoly because it is most efficient for one operator to provide the service. To ensure consumers are not overcharged, grid operators are overseen by a regulator.

In this activity about chemistry and electricity, learners form a battery by placing their hands onto plates of different metals. Learners detect the current by reading a DC microammeter attached to the metal plates. Learners experiment with different metals to find out what combination produces the most current as well as testing what happens when they press harder on the plates or wet their hands. Learners also investigate what happens when they wire the plates to a voltmeter.

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 determine the peak in resource extraction. They learn about the limitations of nonrenewable resources, and how these resources are currently used.

Historic energy transitions, primarily driven by fossil fuels, significantly improved human well-being, measured through consumer surplus. In the UK, transitions from stagecoaches to railways to cars, and from candles to gaslight to electric lighting, substantially increased consumer surplus. However, these benefits diminish as societies reach high well-being levels.
