Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

Challenge your young readers with a passage about physical science. After reading about sound waves and electric currents, kids answer five reading comprehension questions about what they have read.

Help pupils see the world through the eyes of a mathematician. As they examine tide patterns, sound waves, and stock market patterns using trigonometric functions, learners create scatter plots and write best-fit functions. 

What is the net effect when two waves interfere with each other? The lesson plan answers this question by helping the class visualize waves through graphing. Pupils graph individual waves and determine the effect of the interference...

What can your class tell about a wave just by looking at it? Using a simulation, physics pupils work through a series of case studies to determine the effects of speed, frequency, and density on waves. Part of a larger playlist on waves...

What do physicists and musicians have in common? A lot more than you might think. After first viewing a slide show presentation and completing a series of skills practice worksheets on the physics of light, sound, and...

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...

Since light travels faster than sound, some people may appear bright until you hear them speak. The presentation covers what sound is, how fast it travels in various mediums, properties of sound, hearing, and the parts of the human...

Don't string your class along! Physics scholars discover the fascinating forces behind the music of stringed instruments using an interactive. From a series covering sounds and waves, the interactive asks users to identify nodes and...

Ever wonder what really goes on inside a clarinet? Show your young scientists the physics of open-end air columns through an easy-to-use interactive. Learners examine the features of standing waves and calculate frequency and length in a...

Physics is like music—practice makes perfect! Challenge your class using an interactive that builds harmonic skills. The engaging lesson from a playlist exploring sounds and waves revolves around wave behavior in closed-end air columns....

Learners explore the science of sound by considering the characteristics that make unique sounds. Through an interactive simulation, they adjust tension and string size and view the corresponding wavelength and amplitude changes. 

Physics class sure can have its ups and downs! The first in a series of seven interactives from the Waves and Sound series introduces young learners to the concept of wavelength. Scholars work through the interactive to discover the...

Get the ball rolling with this upper-elementary science unit on forces and motion. Offering over three weeks of physical science lessons, this resource is a great way to engage the class in learning about simple machines, friction,...

Bring the ocean floor to life! Earth science scholars discover the process of deep sea mapping in the third installment in a series of five lessons about ocean exploration. The teacher's guide includes helpful resources, worksheets, and...

Determine the speed of a sound wave through an alien atmosphere. You must also find the frequency of the wave source and the wavelength of the wave.

A site for students to practice viewing two sound waves interference and analyze the patterns formed.

By the end of this section, you will be able to define antinode, node, fundamental, overtones, and harmonics; identify instances of sound interference in everyday situations; describe how sound interference occurring inside open and...

This tutorial looks at the behavior of sound waves, specifically focusing upon sound interference and beats. Learn more about it and then take a short quiz to check your understanding.

Students discover factors that affect the speed of sound waves through a medium with illustrated examples and interactive practice problems.

This physics tutorial invites users to discover how sound is a pressure wave. Be sure to view the animation.

By the end of this section, you will be able to define intensity, sound intensity, and sound pressure level and to calculate sound intensity levels in decibels (dB).

In this problem you must determine the intensity of a sound wave when it reaches a given location away from its source.

This physics tutorial invites users to discover that sound is a mechanical wave. Be sure click on the animation for further study.
