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...

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...

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...

It's the encore to a wave unit. Individuals build either a slap tube, flute, or xylophone as a culminating activity for a physics unit on waves. Scholars calculate the lengths of pipes needed to produce the specific notes for their...

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...

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....

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...

Toys are great for learning about physics. Scholars use Slinky® toys to study Newton's laws of motion and types of energy. After a little play, they then model longitudinal and transverse waves with the Slinky® toys.

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,...

STEM scholars investigate sound attenuation by conducting an experiment in which they compare the farthest distance that they can hear a sound with and without ear protection.

A radio receives radio signals, converts them to an electrical signal, then converts this signal to a sound signal, and amplifies the sound so people can hear it. Class members use this information to create a short-wave radio antenna...

Make science come in loud and clear. Pupils learn about how a speaker works by building one. The scholars first learn about electromagnetic fields by building an electromagnet. Using that knowledge, they build a crude speaker using a...

How can you recognize bullying? How is verbal bullying different from physical or social bullying, and when has a joke gone too far? Learners use their own experiences and ideas to inform the discussion.

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...
