Learning about waves can have its ups and downs, but a demo-packed tool kit has the class "standing" for more! Learners gain experience with several different wave types, organizing observations and data, and wave...

Did you realize the visible light spectrum is less than three percent of the electromagnetic spectrum? A hands-onlesson includes five activities and experiments for scholars to explore and discover many advanced science concepts. They...

[Free Registration/Login may be required to access all resource tools.] The speed of electromagnetic waves, their wavelengths and frequencies and how to calculate wavelength or wave frequency.

Light travels as waves. Waves can be described by their amplitude, wavelength and frequency. The speed of a wave can be calculated from its frequency and wavelength.

Students will investigate the properties of light waves. They will learn about the different types of electromagnetic waves and mechanical waves, and investigate the phenomena of reflection, refraction, interference, and diffraction.

Light travels as transverse waves and can travel through a vacuum. Sound travels as longitudinal waves and needs to travel through a solid, liquid or gas. Read about the properties of light and of sound, and learn the differences between...

Through informational text, interactive activities, practice problems, and virtual simulations, students explore the properties of electromagnetic waves.

How can scientists lump heat, light and sound together when investigating properties and behaviors? This learning module will address that question through a series of activities.

Students are presented with a challenge question concerning color blindness and asked to use engineering principles to design devices to help people who are color blind. Using the legacy cycle as a model, this unit is comprised of five...

[Free Registration/Login may be required to access all resource tools.] Students learn what an electromagnetic wave is, gain a feel for the main parts of the spectrum, and work on problems involving basic properties of electromagnetic...

A video and a short quiz on how sound travels in waves, its properties, and how to measure it.

This lesson will introduce the electromagnetic spectrum and the properties and uses of the waves it contains. It is 2 of 4 in the series titled "Electromagnetic Spectrum."

This lesson will introduce the electromagnetic spectrum and the properties and uses of the waves it contains. It is 1 of 4 in the series titled "Electromagnetic Spectrum."

Learn about the properties of materials in their interactions with light, including whether they are opaque, transparent, or translucent, and which of these produce shadows.

[Free Registration/Login may be required to access all resource tools.] Students will understand the photoelectric effect and that light has both particle and wave properties. Includes a simulation for exploring the photoelectric effect.
