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...

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.

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...

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

A video and a short quiz on the basic concepts and vocabulary for understanding light energy.

The Sound and Light unit provides students with an understanding of sound and light waves through the theme of the "Sunken Treasure," a continuous story line throughout the lessons. In Lessons 1-5, students learn about sound, and in...

[Free Registration/Login may be required to access all resource tools.] Students investigate and analyze characteristics of waves, including velocity, and calculate the relationship between wave speed, frequency, and wavelength.

All waves will reflect and refract in the right circumstances. The reflection and refraction of light explain how people see images, color and even optical illusions. This tutorial discusses each concept and presents an experiment to try...

A unit on energy, force, and motion presented with interactive and classroom activities. Students gain an understanding of weight, mass, potential and kinetic energy, sound, and heat with this engaging resource.

Through nine lessons, students are introduced to a range of energy types--electrical, light, sound and thermal-as well as the renewable energy sources of wind, hydro (water) and solar power. Subjects range from understanding that the...
