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...

Which travels faster, light or sound? Scholars work in groups to simulate the ability for waves to travel through solids, liquids, gases, and through a vacuum. Then, they learn about the properties of a mystery wave and must determine...

Four modules are a part of this stellar lesson plan. Space scientists view the electromagnetic spectrum, they generate waves on a computer screen in order to measure frequency and wavelength, discover how light is related to temperature,...

Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...

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 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...
