Upon viewing the Magnets and Electromagnets video series, students will be able to do the following: Define a magnet as a material that attracts iron and materials containing iron. Explain that magnets have a north pole and a south pole...

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...

Today I play the "Close-Up Christmas Challenge" with Greg! Using my special microscope camera!

In this video, we are going to be looking at Inverse proportion. You may have already looked at direct proportion, which is how we describe the relationship between two quantities which grow by the same scale factor.

This video provides a concise overview of how electrical generators produce electricity, using various power sources such as water, steam, coal, gas, oil, and nuclear energy. This video is part of the 11-part series, Electromagnetism.

You may be familiar with permanent magnets—the kind that hang on a refrigerator. But did you know that other magnets, called electromagnets, can be turned on and off? When turned on, electromagnets act just like permanent magnets, but if...

This video provides an introduction to basic concepts in magnetism, including magnetic poles, magnetic fields, and electromagnets.

How do we create linear equations to solve real-world problems? This video explains the process.

This video provides a brief overview of the life and inventions of Alexander Graham Bell, focusing on his invention of the telephone and his contributions to the education of deaf individuals. It highlights key events and achievements in...

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...

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, the teacher explains the concept of an electric circuit using a simple light bulb example. The video also highlights the importance of wires and a switch in controlling the flow of electricity.
