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...

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...

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...

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...

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...

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...

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,...

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...

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...

You matter, unless you multiply yourself by the speed of light ... then you energy. Presentation covers the behavior of light as both a wave and a particle, light versus sound, space travel, why objects have colors, depth perception,...

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...

Sometimes it's okay to rock the boat! Science scholars manipulate wave properties using a fun interactive. Part of a larger playlist that dives into waves and sound, the lesson helps users work their way from apprentice to wizard by...

Several times throughout history, groups of soldiers marching in rhythm across a suspension bridge have caused it to collapse. Scholars experiment with pendulums, resonance, and force to determine why this would happen. First, pupils...
