Not all waves travel across the ocean or across the universe. Some are stuck in a certain spot! Like the vibrations of the strings on a guitar. What's the deal with these standing waves? And what's this, quantization? Oh my! We'd better...

In this video, we explore the structure, physiology, and sensation relayed by the Dorsal Columns/Medial Lemniscus (DCML) pathway.

In this live-action program viewers will learn that the larynx is an organ in the neck. It is crucial for speech and breathing. Students will come to understand the larynx controls airflow during breathing, protects the airway during...

Scientists study earthquakes so we can understand them better and hopefully one day predict them so we can save thousands of lives. A seismograph is a tool scientists use to record earthquakes and measure their strength. In this activity...

This video introduces the concept of overtone singing, a technique used by trained vocalists to sing more than one note at a time. It explains how voice is produced and the role of vocal cords, and then delves into the production of...

Helping children relate to the topics they study is what the Real World Science series of videos does best. Real World Science: Sound helps students learn the principles of sound, the range of human hearing and significant terms, as they...

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,...

When you hear the roar of traffic, the bark of a dog, or your teacher's voice, you are experiencing sound. This program uses colorful animations to explore important characteristics of sound, including intensity, loudness, pitch, and...

Elisa Konofagou, a bioengineer at Columbia University, believes ultra sound technology could become be a vital component in treating and perhaps curing degenerative brain diseases such as Cancer, Alzheimer's and Parkinson's disease. One...

Upon viewing the What is Sound video series, students will be able to do the following: Understand that sound is produced when matter vibrates. Explain that sound energy can travel through air, liquids, and solids, which are generally...

This video explores the characteristics of waves. It explains the speed of waves, how this value is calculated and the four basic interaction between waves. Other terminology includes: vibration, crest, trough, amplitude, wavelength,...
