What does our planet look like from space? Most are familiar with the beloved images of the blue marble or pale blue dot -- Earth from 18,000 and 3.7 billion miles away, respectively. But closer to home, within the...

The video discusses the concept of light as a type of electromagnetic radiation and explains the different types of radiations in the electromagnetic spectrum based on their wavelength, frequency, and energy. It also highlights the...

Students will learn about the different layers of the atmosphere. The changes in the atmosphere are explained using examples of contemporary environmental conditions brought about by human behavior. The oxygen cycle and the carbon cycle...

This is a lecture video on radio waves where the instructor explains how radio waves are produced and used to communicate around the world. The video covers the electromagnetic spectrum and explains that radio waves are a classification...

Microwave ovens use radio waves to quickly and efficiently cook food by agitating water molecules and generating heat at the atomic level. The waves can pass through certain materials such as plastic, glass, and ceramic, making heating...

Up until a couple centuries ago, we had no idea what light is. It seems like magic, no? But there is no magic in this world, really. Just stuff we don't understand. So let's understand light a little better right now!

The basic nuts and bolts of how things work is explained simply by exploring the natural world and human made inventions that we come in contact with. Drones are used for all kinds of things from military missions to movies to delivering...

Learn how a radio works, from transmitting electrical energy through radio waves to converting them back into audio for the user to listen to. Understand how signals are encoded and decoded using modulation techniques, as well as the...

In this lecture video, the different types of electromagnetic waves are examined, and their uses and applications are explored. The video begins with an overview of the electromagnetic spectrum, starting with gamma rays and ending with...

Resonance is introduced and demonstrated using a “singing rod”, a swing, a goblet, a hollow tube in water, a hollow tube open on both ends, a seashell, a broken speaker, a human body and a key fob, and a shorter “singing rod”....

An introduction to mechanical waves which are defined and demonstrated. The fact that the medium is not displaced is demonstrated. Both transverse waves and longitudinal waves are also defined and demonstrated.

This video is a lesson about sound and how it works. It covers topics such as the definition of sound, how sound is produced through vibrations, the different types of waves (transverse and longitudinal), the speed of sound in different...

Upon viewing the The Nature of Waves video series, students will be able to do the following: Define waves as traveling disturbances that carry energy through matter or space. Explain that waves do not actually move matter. Instead,...

This program explores the fascinating features of vibrations and waves. Vivid examples of these phenomenon help students understand how sounds are formed, how light travels, and how ocean waves move. Special attention is also given to...
