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 multiple...

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

The conversion of sound into light is a fascinating phenomenon that is a side effect of pistol and mantis shrimp stunning their prey. It is known as sonoluminescence, and it is thoroughly delineated in this fascinating little video. Add...

Listen in as Mia and Sam expound on sound. It is caused by vibrations and travels in waves. It has the qualities of pitch, frequency, and volume. This hip animation displays a graph to depict the frequency and amplitude of sound waves....

Reflection is the bouncing of waves. Reflection can be used simply as entertainment or to guide ocean navigators. As your physics aces begin learning about waves, this resource would be valuable to show them that all of the different...

This is a continuation of Mr. Noon's demonstrations on the physics of sound. Watch part one to pick up some tips on how to teach sound to your high school physicists or get ideas for activities for them to try.

Take a field trip to the Children's Museum of Virginia with your elementary scientists. In this video, the museum's curator explains how sound travels. With huge tubes, she shows how the difference in vibrations per second changes pitch....

In this first of two parts, Mr. Noon walks around his physics class demonstrating how sound waves move. Ironically, the sound is off from the visual in this video! Use this illustrative video to learn about different demonstrations you...

Students design and construct a listening device that will allow them to listen to the sound generated by specific object inside a box.

This wave and electromagnetism assignment is so thorough, it could be used as a unit exam. The first section of it covers wave concepts. The next section addresses static electricity. There is a section that deals with electric circuits....

Dangle a spring to experiment with vibration and discover if period is dependent on amplitude. Strum a guitar and adjust the strings to compare displacement and sound. Use a Slinky® and guitar strings on a ring stand to uncover the...

Young scientists investigate the scientific concepts and principles that help make common toys such as hula hoops, yo-yos, slinkies, and silly putty work. As a class, they read "Backyard Rocket Science, Served Wet" to get a look behind...

A phenomenal lesson on sound is here for your third graders! In it, learners engage in hands-on activities, watch video, take part in Internet activities, and complete tasks in cooperative groups in order to explore the world of sound...

Groups rotate through a series of stations and work with a partner to observe sound waves. Children describe sound in terms of pitch, volume, and frequency. To apply their new knowledge, the class considers how these observations can...

New ReviewMusicians and physicists unite for an activity that explains frequency using the guitar as an example. Scientists view an animated video defining frequency and explore pitch changes. During the activity, tension changes on guitar strings...

New ReviewFuture physicists pump up the volume while discovering the world of sound waves. Group members learn about the qualities of sound waves, the relationship between energy and sound volume, and the definition of amplitude while viewing an...

Hear about a great resource on sound? An interesting hands-on activity has learners construct a device that will soundproof a phone or speaker. They test out different materials to see which ones best absorb sound waves.

Not all sandwiches are tasty. Scholars use basic materials to build an instrument called a sound sandwich. They see how blowing on the instrument causes rubber bands to vibrate, which produces sound waves.

Using a home-built hydrophone, pupils investigate how things sound in water. Learners listen to sounds created in air and then compare that to the same sound picked up by the hydrophone. Individuals compare the loudness and the pitch of...

How loud was that? Individuals build wheels displaying different sounds. Then, learners use the wheels to find the number of decibels the sound creates and how long they could withstand the sound before potential hearing damage.

Visualize vibrations within the classroom. Pupils see the connection between sound and waves. The learners use a tuning fork in two different ways to demonstrate the waves associated with sound. Scholars see how the sound waves from a...

Catch the fast wave. Using a computer simulation, pupils experiment with amplitude, frequency, damping, and tension of a string to determine which affects the speed of the wave. Learners record the observations to determine their...

Pupils construct and play various musical instruments made from straws and bottles. They investigate how changes in their instruments result in tone changes. Learners change the lengths and amount of water in the instruments and record...

Here comes the sound. After watching a couple videos demonstrating and explaining the Doppler Effect, learners develop their own understanding of the phenomenon. Scholars draw a sound wave and observe how the perception of the wave...
