Echolocation Class Activities
Echolocation and SONAR Part I
Students explore the speed of sound and identification from a distance. The activity concludes with a fish finding activity.
Echolocation and SONAR Part II
Students explore the idea of how it feels to use sound to locate objects and experiment with having to search for objects above and below them, not just side to side
Echolocation: Speed of Sound & Identification from a Distance
Students explore the speed of sound by experiencing the delay for sound to reach them and they will experience identifying objects from various distances.
Echolocation: Sound Rather Than Sight
In this activity students explore the idea of how it feels to use sound to locate objects.
Echolocation: 3D Location
In this activity students experiment with having to search for objects above and below them, not just side to side.
Echolocation: Fish Finding Game
A group of students play either a dolphin, an object or a fish and practice echolocation!
Echolocation: How Dolphins Use Sound
Students learn about people and animals that use echolocation through video and discussion with their peers.
Echolocation Pre/Post Test
This is a combination open-ended and likert-scale quiz covering many of the learning goals from the two echolocation activities. I used it with pre-service elementary teachers but it has not been reviewed by others.
Echolocation Wrap Up
Students go through a PowerPoint that puts the echolocation topics together and helps them understand why and how echolocation works.
Students are asked to watch a couple of videos about humans that use echolocation and then visit the Discovery of Sounds In The Sea website to hear dolphins and whales use echolocation.
Basics Of Instruments Unit
How Music is Made
Students make their own straw instruments and cup instruments to investigate how music is made. They also blow over the top of bottles and investigate an acoustic and electric guitar. I used Generalizing Musical Instruments in class as a necessary follow up to this lab.
Musical Instruments Part I
Students investigate how instruments make sound by creating their own “straw instrument” in this in-class inquiry activity.
Musical Instruments Part II
Students experiment with various sounds sources, including their voice, cup instruments, and guitars, to determine the source of sound and how to change pitch and volume.
Generalizing How Musical Instruments Work
Students use their background knowledge to make generalizations about how instruments work. This lesson was designed for use after the Sound and Music introductory lesson and Musical Instruments Part I and Part II
Sound and Music
Introductory hands-on, minds-on activity to the science of sound, music and our ears. This lesson goes with our Teacher Activity Kit.
Resonance is too much!

Complete set (105 pages) of Dangerous Decibels materials in pdf format for downloading.
The Classroom Program
The classroom program is a one class period interactive program on how to protect your ears.
Interactive lesson demonstrating the connection between sound and vibrations.
Bend It, Break It
Interactive lesson modeling the fragile hair bundles of the inner ear.
How Loud is Too Loud
Students explore sound levels and exposure time for a variety of sources.
Students use a sound level meter to measure, compare and graph sound levels in different environments.
The Science of Dangerous Decibels
Description of the physics of sound presented at a straight-forward conceptual level.
Adapting to Different Grade Levels
Description of which activities work at different grade levels.
Protect your ears Coloring Sheet
Coloring Sheets – warning signs on how to protect your ears from loud sounds.
Intensity Level Activity
Students use sound level meters to investigate how sound level drops off with distance. 20- 25 minutes.
Pre/Post Conceptual Test for Sound and Music
Multiple-choice test designed to measure learning from the Sound and Music lesson.
Sound and Wave Basics
This is a small homework assignment working with the PhET simulation on sound and waves.
This lesson follows up on the Sound and Wave Basics Homework, introduces the terminology used to describe waves, investigates what factors impact wave speed, demonstrates interference, and provides multiple ways to think about natural frequency and resonance.
Speed of Sound
20–30 minute set of slides with peer instruction on the topic of the speed of waves on strings and how helium and sulfur hexafluoride affect the voice. Brings back the concept of resonance.
Why Mosquitoes Buzz in People’s Ears
This activity integrates literature into a science lesson about how vibrations cause sound.
How to Wear Earplugs
5 minute video demonstrating the proper way to roll and fit foam earplugs.
Loud Sounds Book Marks
Two sided full color bookmarks show sound level for certain sounds and time limits for different levels.
Doppler Effect and Sonic Booms
Combination of problems and conceptual ideas related to the Doppler Effect and Sonic Booms including Mach number calculations. Introduction to Standing Waves follows.
Giant Acoustics Word Search
36 word word search uses acoustics terms found in the physical science lessons. Minimum of 2 hours to complete.
Graphing Waves and Ultrasound
This set of slides lasts 20 minutes and reviews traveling wave pulses and then introduces the idea of translating from position graphs to history graphs. Medical applications of sound waves are presented next and then a brief introduction to electromagnetic waves and how they relate to sound. Used with CT focused Ultrasound article.
This power point includes more than an hour of slides which have a section on speech intelligibility, acoustician careers, follow up to the Waves and Harmonics lab and the Sound rather than Sight activity found above.
Middle School Sound Activities
An index of materials that have been tested and reviewed for use with middle school students
Simple Harmonic Motion
PowerPoint slides for an interactive lesson on simple harmonic motion including peer instruction and in class practice problems. Approximately 70 minutes of material over restoring force, period and frequency of springs and pendula, equations of motion for SHM and conservation of energy.
Simple Harmonic Motion Lab
Students investigate a spring, a pendulum and pasta w/raisins or marshmallows to determine if the period depends on length, amplitude and mass for each oscillator. Finally students are asked to determine if the pasta w/ raisins or marshmallows is more like a spring or pendulum (the answer is not what they expect!)
Two sound labs using both LabPro and Xplorer GLX. These two lessons each use a sound probe to investigate how wave patterns from different sounds look, including their voices and their straw instruments.
Peer-Instruction Type Questions for Sound
Selection of clicker questions related to above sound activities
Spring into Another World
This lab is by Hewitt and Baird’s Conceptual Physics Laboratory Manual. It uses the PhET simulation Masses and Springs to investigate Hooke’s Law. I used it and Simple Harmonic Motion together in one lab period.
Students use the Sound simulation from the PhET Interactive Simulations to understand how different sounds are modeled, described and produced. They also design ways to determine the speed, frequency, period and wavelength of a sound.
Standing Waves Lab
Standing waves are studied experimentally with vibrators and a string. Students are tasked with figuring out a method for determining the density of their string and then comparing results with the rest of the class. At the end they write up a plan for a more ideal experiment to determine the mass density of their string.
Waves and Harmonics Lab
This lab uses Fourier: Making Waves PhET simulation to investigate auditory perception of various combinations of harmonics as well as how waves add.
Anatomy of a Wave
Students take on the roles of reporters and artists to draw and describe the nature of transverse waves.
Students experience the Doppler effect through videos, discussion, and teacher demonstrations.
Tuning Fork Discovery with Study of the Science of Sound
Students examine a brief history of the discovery of how sound works and then use tuning forks to experiment with how sound works.
Students explore the PhET Interactive Simulation “Wave on a String” focusing on amplitude and frequency as well as wave travel.
