What You'll Learn
How electricity is made
Susan Mayes' book, "Where Does Electricity Come From?" is a great resource for young minds wanting to learn about electricity. The book provides a clear and concise explanation of how electricity is generated and used, making it a perfect introduction for elementary and middle school students.
The process of electricity generation involves various methods, and the book likely covers the most common ones. One common method of electricity generation is through the use of power plants that utilize fossil fuels such as coal, oil, or natural gas. In these plants, the fuel is burned to heat water and produce steam, which then turns turbines to generate electricity.
Another method of electricity generation is through nuclear power plants. These plants use uranium or plutonium to heat water and produce steam, similar to fossil fuel plants, but the process does not involve burning fuel. Instead, nuclear fission reactions release heat to produce steam and generate electricity.
Renewable sources such as wind, solar, and hydropower are also important for electricity generation. Wind turbines convert the kinetic energy of wind into electrical energy, while solar panels absorb sunlight and convert it into electricity through the photovoltaic effect. Hydropower plants utilize the force of moving water in dams or rivers to turn turbines and generate electricity.
Additionally, the book by Susan Mayes might also explore the use of batteries and telephones in relation to electricity. Batteries, for instance, are electrochemical devices that store chemical energy and convert it into electrical energy when needed. Telephones, on the other hand, rely on electricity to transmit and receive signals, enabling communication over long distances.

How batteries work
Batteries are devices that accept, store, and release electricity on demand. They use chemistry, in the form of chemical potential, to store energy. Batteries consist of two electrical terminals called the cathode and the anode, separated by a chemical medium called an electrolyte.
When a device is connected to a battery, chemical reactions occur on the electrodes that create a flow of electrical energy to the device. During a discharge of electricity, the chemical on the anode releases electrons to the negative terminal and ions in the electrolyte through an oxidation reaction. Meanwhile, the cathode accepts electrons at the positive terminal, completing the circuit for the flow of electrons. The electrolyte allows the flow of electrical charge between the cathode and anode, putting their different chemicals in contact with one another.
In a rechargeable battery, electrons and ions can move in either direction through the circuit and electrolyte. When the electrons move from the cathode to the anode, they increase the chemical potential energy, charging the battery. When they move in the opposite direction, they convert this chemical potential energy to electricity in the circuit and discharge the battery.
The voltage of a battery refers to the force at which the reaction driving the battery pushes electrons through the cell. It is also known as electrical potential and depends on the difference in potential between the reactions occurring at each of the electrodes. The higher the voltage, the more work can be done. Current refers to the number of electrons passing through any one point of a circuit at a given time. The higher the current, the more work it can do at the same voltage.
Over time, the chemistry and structure of battery materials can change, reducing battery performance and safety. Each charge cycle degrades the electrodes a little more, causing a loss in performance over time, even in rechargeable batteries.

How telephones work
Susan Mayes' book, 'Where Does Electricity Come From?', provides an overview of how electricity is made and used, covering various topics such as electricity at work, electricity and light, and how a telephone works. While the book does not go into detail about the inner workings of telephones, it is a valuable resource for young readers to learn about electricity and its applications.
Now, let's delve into the topic of how telephones work. The telephone has revolutionized communication, allowing people to connect and converse across vast distances. Here's a step-by-step breakdown of the process:
- Sound Conversion: Telephones convert sound, which is a mechanical wave, into electrical signals. This process is made possible by a component called a microphone, which is present in the mouthpiece of the telephone.
- Electrical Signals: When you speak into the mouthpiece, the microphone captures the sound waves and converts them into electrical signals. These signals are then transmitted through the telephone's circuitry.
- Transmission: The electrical signals representing your voice travel through the telephone network, either via traditional copper wires or modern fibre optic cables, to reach the intended recipient's telephone.
- Receiving: At the receiving end, the electrical signals are converted back into sound waves through a speaker, allowing the person on the other end to hear what you are saying.
- Dialing and Connecting: To make a call, you dial the phone number of the person you wish to reach. This initiates a series of processes within the telephone network, including switching and routing, to establish a connection between your phone and the recipient's phone.
- Network Infrastructure: Telephone networks consist of a complex system of wires, cables, switches, and exchanges that enable calls to be routed from one phone to another, even across long distances or internationally.
- Advanced Features: Modern telephones offer additional features beyond simple voice communication. These include caller ID, call waiting, voicemail, and, in mobile phones, a range of digital capabilities and internet-based services.
While Susan Mayes' book provides an introduction to the topic of telephones and their relationship with electricity, the above paragraphs delve deeper into the mechanics of how telephones function, offering a more comprehensive understanding of this essential mode of communication.

Power from water
Water can be a powerful force in nature, and its power can be harnessed to create electricity. This force, called waterpower or hydropower, has been used for over 5000 years. The first use of hydropower in antiquity was to draw water with vessels made of bamboo cane or clay to irrigate fields. The use of hydropower has played an important role in the development of humankind, and it continues to be a significant source of renewable energy today.
Hydropower plants are one of the most common ways to generate electricity from water. These plants use the energy from flowing water to turn turbines, which then produce electricity. The water used in these plants is often collected at a higher elevation in a reservoir and then led downward through large pipes to a lower elevation. The falling water causes the turbines to rotate, and the rotating turbines run generators that produce electricity. Pumped storage power plants, a type of hydropower plant, can also store large amounts of energy from the electricity grid and help stabilize the electrical grid during peak demand.
Another method of generating electricity from water is through geothermal energy. In some places, such as Iceland and California, seismic activity breaks up the rocks, allowing water to circulate near geologic hotspots. Steam then rises to the surface, where it can drive generators. In other cases, cold water can be pumped down through wells to be heated, and the hot water is then extracted to drive turbines.
Additionally, researchers are exploring ways to use hydrogen from water as an energy source. While most of the world's hydrogen supply currently comes from fossil fuels, there is potential for using water as a source of hydrogen to produce electricity. The U.S. Navy, for example, has developed a method for turning seawater into jet fuel by splitting water into hydrogen and oxygen and then combining the hydrogen with carbon dioxide.
Water can also be used to create electricity in more innovative ways. For example, French scientists have developed a device that converts the vibrational energy of a raindrop hitting a special plastic into electricity. While this invention may not produce a lot of power, it could have advantages over solar energy as it would work in the dark and during rainstorms.
