Resonate with the class. By watching a couple of videos, pupils realize that sound waves require a medium to travel and can break glass. They then listen to a lecture on resonance and work through a lab to calculate the speed of sound...

Explore how sound travels as waves with a straightforward lesson that explains the basics of waves in relation to sound. The presentation considers sound waves in both open and closed pipes and shows how to calculate wavelength and...

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...

Which travels faster, light or sound? Scholars work in groups to simulate the ability for waves to travel through solids, liquids, gases, and through a vacuum. Then, they learn about the properties of a mystery wave and must determine...

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.

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...

Take a stretch, but don't wave goodbye. An interesting resource provides everything needed to present an introductory lesson plan on waves. Teachers present a PowerPoint defining the types of waves and their characteristics. Pupils use a...

Ancient people used musical pipes as early as the third millennium BCE. Young scientists explore the workings of musical pipes to better understand the relationship with frequency, length of pipe, and sound waves. They determine 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...

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 is a physicist's favorite part of sports? Doing the wave. The presentation covers longitudinal, transverse, surface, and standing waves. It includes in-depth information on frequency, wavelength, period, amplitude, reflection,...

What causes sound? Groups of sound detectives use a variety of tools including ping pong balls, pasta noodles, raisins, rubber mallets, and a tuning fork to investigate what causes sound. The young Sherlocks conduct a series of...

Sound engineers investigate the structural design of a musical instrument, the recorder. They work in collaborative groups to choose an instrument to build out of everyday craft materials. It must be able to repeat a three-note sequence...

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...
