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...

A colorful and comprehensive PowerPoint highlights this lesson on waves. Junior geophysicists pretend that they are hired to analyze seismic waves. A worksheet is provided to go along with an online article about how compact discs work...

Introduce starting space scientists to the electromagnetic spectrum, expecially the portion of visible light. Teach them about wavelength and frequesncy. Then give them a roll of adding machine tape and a manila folder to make a...

Students design a program to make an automated vehicle perform a specific task. In this robotics lesson, students play the role of scientists competing to win a factory's contract. They present their algorithm to class.
