Students examine the phenomenon of sounds traveling slower than light. They discover why they see things before they hear them and how to estimate the speed of sound as homework.

Third graders measure the speed of sound using scientific investigative techniques.

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...

Second graders identify the different function and parts of the ear. In this physics lesson, 2nd graders explain how we hear sound. They read about the life of Helen Keller and respond to questions that follow.

First graders construct a KWL chart on sound. In this physics lesson, 1st graders describe different ways to produce sound. They explain how sound waves propagate.

Construct a maze in your classroom and have a blindfolded scientist act as a space rover, maneuvering unfamiliar terrain while another scientist plays commander. Classmates record the number of occurrences of the commander having to...

Pupils discuss sound and how it's measured, and through experimentation and implementation of the scientific method, they determine the speed of sound.

Students discuss physical places in which had good or bad acoustics. After reading an article, they discover the relationship between the physics of sound and concert hall acoustics. They calculate the speed of sound and compare their...

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...

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....

Should democracies include hate speech as a protected right? Scholars analyze the rights found under the First Amendment to the Constitution through researching evidence. Freedom of expression becomes the focal point of the...

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...

Pupils experiment with measuring the speed of sound in an open field by clapping hands and measuring the time delay between the clap and hearing the sound at a long distance. Students practice solving equations at completion of activity.

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...

Fifth graders explore and examine the basic properties of sound. In pairs, they speak through a balloon and listen to the sound vibrations, and listen to a ticking clock or watch through a variety of materials and identify the...

Learners investigate the concept of velocity and apply it to the velocity of sound and measure the velocity of sound by measuring the echoes produced in a tube. They show their calculation of time and speed, and then conclude that sound...

Sixth graders use a laser along with computer microphone probeware and the appropriate software, 6th graders determine the speed of rotating objects.An audio amplifier is connected to a solar cell to change the laser light signal into a...

How fast can you go? Test scholars' letter sound recognition with a timed game. Using letter cards of all the letters you've learned so far, learners take turns flipping cards and correctly saying the letter sound. Model this first,...

Explore reading for fluency and speed with your class. They discuss reading faster, smoother, and with more expression. Practice reading with fluency using one minute timed reads. They read "Tin Man Fix-It." and record how many words...

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...

Third graders view a PowerPoint and participate in an experiment about sound.  In this sound instructional activity, 3rd graders press on a slinky with different amounts of force to understand energy waves moving and echoing back....

Learners discover how sound is produced and how sound travels. Through inquiry, problem solving and hands-on activities, students explore high and low sounds and the mediums in which sound travels best.

Students observe how sound waves would look and behave if we could see them. They determine ways the model is accurate and inaccurate based on actual sound waves.

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...
