Now Hear This!

Time to witness the effects of sound. Learners analyze different materials to determine their abilities to absorb sound waves. They use free software to monitor the amplitude of the waves to verify results.

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...

If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels....

Practice the skill of compare and contrast. First, show learners the different pairs of artwork in the project packet (included). Then, each learner chooses one of the pairs and finds the similarities and differences between the...

Beautiful music doesn't just write itself, but if you ever feel bad about procrastinating, remember that Mozart wrote the overture to Don Giovanni the morning it premiered. Introduce young scientists to the elements of sound including...

Add a little music to your next physics class. Pupils discuss how frequency determines pitch and take part in several activities designed to teach them more about sound, melody, resonance, and vibrations. They use materials to construct...

What makes sound possible? Answer this question while viewing the 18th lesson of a complete Crash Course physics series. After discussing waves in previous lessons, the narrator applies those characteristics to sound waves and their...

It's better to burn out than fade away! Viewers experience the birth of neutron stars and supernovae in a video that explains the life cycle of high mass stars. Learners see the conditions needed to produce these events, as well as...

Known as one of the most iconic advertisements of the 20th century, Macintosh's "1984" commercial has become more of a social statement. Present the ad to a new audience of viewers with a lesson focused on identifying dystopian...

Using a karaoke machine, a guitar, and other devices, learners explore the way sound waves travel. Using this hands on approach, learners can get a better understanding of wavelength, frequency, and more.
