The flick of a switch, that’s how easy it is to get electricity, right? If you’re one of the lucky ones, then yes. But in 2017 there are still over 1 billion people who do not have access to electricity. In this video we will discuss how...

This video explains the basics of electricity and its various applications in everyday appliances. It introduces the three effects of electric current - heating, magnetic and chemical - and how they are used in different devices. It also...

Why do some substances conduct electricity, while others do not? And what is a semiconductor? If we aim to learn about engineering and technology, this will be a very important concept, so let's go through the basics now!

Growing your own pure copper crystals is very easy.

You only need the follo
wing:
-A suitable container (flat walls are better, you can observe the growt
h better!)
-
Copper Sulfate.
-A power supply. 5 volts or less...

Water on Earth focuses on water as most kids would think about it. We start with water in obvious locations such as oceans, lakes, and rivers. We quickly learn that water can change phase to remain a solid in glaciers. Many kids may be...

Electrical engineering can be broken up into various concentrations. The main one's I discuss in the video are power, electronics, RF, and controls. Students who enter into electrical engineering will all take mostly...

Mortgage rates remain near historic lows as a result of the Fed's efforts to boost the economy amid the COVID-19 pandemic. Here's how hopeful and current homeowners can benefit.

When lightning strikes trees and other tall objects, it doesn't just stop. It may run along or just beneath the ground where the intense heat turns soil moisture into steam that blows the soil outward, to instantly create what is called...

Watch this 'how-to-play' video with your grade 3 or 4 class, and then set it up out in your sports hall. Students practice their mental division and multiplication, while combining different sport skills.

Water on Earth focuses on water as most kids would think about it. We start with water in obvious locations such as oceans, lakes, and rivers. We quickly learn that water can change phase to remain a solid in glaciers. Many kids may be...

Lightning is spectacular, from a distance. It's nature's way of transferring electricity within the sky, or between the sky and the ground. When lightning is nearby, it is a threat to safety. People are struck by lightning, in many cases...

Open vs. closed circuits are demonstrated. Conductors and insulators are shown in circuits. Resistivity is defined and the equation is analyzed. Resistivities of common materials are shown. Semiconductors are discussed. The temperature...

This video covers how imaginary numbers are used to solve real worlds problems in math, science, and engineering as well as a derivation of the most beautiful equation in math. The main topics include signals, controls, quantum...

In this video, the teacher explains the two major types of circuits: series circuits and parallel circuits. They describe how the arrangement of the parts in a circuit determines its type. This video is part of the 8-part series,...

This video provides a brief overview of the importance of safety mechanisms like fuses and circuit breakers in preventing fires and electrical accidents caused by short circuits and overloading. It explains how these mechanisms work...

In this video, we learn about electric circuits and their components.<b<br/>r/>

This video is part of the 8-part series, Electrical Circuits.

This program uses real circuits and circuit diagrams involving batteries as the power source to demonstrate how batteries work and what it does for a circuit. The video shows how batteries work in a series and parallel circuits....

This video is a review of the topics covered in the Electrical Circuits series. This video explores the fascinating characteristics of electric circuits, including the flow of electric charges, the production of electric current, and...
