Students will discover infrared by repeating Herschel's experiment, learn the relationship between frequency and wavelength, and describe how images are created in infrared light. They will also learn how infrared energy influences climate by studying thunderstorms. As part of an ongoing process, students will apply what they learn by monitoring daily GOES satellite infrared images for severe thunderstorm activity and, in conjunction with the U.S. Weather Service, keep a journal of their severity and location.

In this lesson students will learn the characteristics of sound, how sound travels, and how sound is created and detected.

This instructional video shows educators how to set up a wave machine using wooden kabob sticks, jelly candies, and duct tape. The video also demonstrates how the wave machine can then be used to illustrate various wave properties. Background content on waves and wave energy is also provided.

In this unit of study, students will learn about properties of a wave. Lessons in this unit include: The Anatomy of a Wave; Frequency and Period of a Wave; Energy Transport and the Amplitude of a Wave; The Speed of a Wave; and The Wave Equation. This unit includes questions at the end of each lesson to allow students to self assess and check for understanding.

In this unit, students will learn how to identify the parts of a wave and the terminology associated with waves including frequency, period, and amplitude. Lessons in the unit include: Vibrational Motion; Properties of Periodic Motion; Pendulum Motion; and Motion of a Mass on a Spring. This unit includes animations and mini quizzes to check for understanding and facilitate learning.

In this activity, students explain how an electromagnetic wave differs from a mechanical waves. They will also investigate the relationship between frequency and vibration rate.
