Do radio waves create light? It's more difficult to understand the things we can't see than those that we can. The simulation compares the relatively small range of visible light to the entire electromagnetic spectrum. It graphs the size...

What can your class tell about a wave just by looking at it? Using a simulation, physics pupils work through a series of case studies to determine the effects of speed, frequency, and density on waves. Part of a larger playlist on waves...

Three main factors determine the wave height experienced in the ocean. Scholars use a virtual simulator to alter wind speed, fetch, and duration. Each combination creates a unique wave measured in significant height.

Listen in as Mia and Sam expound on sound. It is caused by vibrations and travels in waves. It has the qualities of pitch, frequency, and volume. This hip animation displays a graph to depict the frequency and amplitude of sound waves....

If you are at a sports match and the crowd starts two waves that are both headed toward you at the same time, what do you do? The simulation applies the concepts of constructive interference and destructive interference to that very...

Does the depth of a pond matter to the waves created when rain is falling? Many people assume the answer is no, but interestingly, it does matter. Pupils explore this concept and other variables related to wave behavior through a...

How can a pan flute sound one note while we hear a chord? The simulation explores sound waves, vibrations, and harmonics at the molecular level. Scholars control the pipe into which air is being blown, the length of the pipe, and which...

Physics class sure can have its ups and downs! The first in a series of seven interactives from the Waves and Sound series introduces young learners to the concept of wavelength. Scholars work through the interactive to discover the...

Don't string your class along! Physics scholars discover the fascinating forces behind the music of stringed instruments using an interactive. From a series covering sounds and waves, the interactive asks users to identify nodes and...

Ever wonder what really goes on inside a clarinet? Show your young scientists the physics of open-end air columns through an easy-to-use interactive. Learners examine the features of standing waves and calculate frequency and length in a...

Physics is like music—practice makes perfect! Challenge your class using an interactive that builds harmonic skills. The engaging lesson from a playlist exploring sounds and waves revolves around wave behavior in closed-end air columns....

Radio waves are all around us! How do they transmit sound? Using an interactive, scholars examine how songs travel through the air. The resource explains the process from the radio station, to signal towers, to the radio unit. A look at...

The study of waves is not a quacking matter! Watch as a duck manipulates the behavior of its waves through its motion. Graphs show the frequency and wavelength of the waves. 

Breakwaters offer marinas and beaches protection from large ocean waves, but how do they work? Scholars observe wave patterns and wave amplitude during the simulation. They control the number of openings, width of openings, distance...

In this online interactive physics quiz worksheet, students respond to 5 questions. Students may check their answers for accuracy.

What happens to radio waves, time, and light in and near a black hole? Young scientists explore what is known about observing frequency and time at various distances from a black hole. They control the size of the black hole and the...

Learners explore the science of sound by considering the characteristics that make unique sounds. Through an interactive simulation, they adjust tension and string size and view the corresponding wavelength and amplitude changes. 

What is the fastest way to get from point A to point B if you are going through two different mediums, such as air then water? Scholars explore the way light travels through air, water, acrylic, glass, and diamond as they answer this...

What determines which ball rolls the fastest — the weight, the radius, the material, or something else? Scholars select two balls to race down the inclined plane, determining their material and radius. As they race, the simulation graphs...

Electricity travels at the speed of light, 186,000 miles per second. Through a simulation, classes see how the structure of energy bands in crystals of atoms determines how materials conduct electricity. Participants can change the...
