Working with Wavelets
In this working with wavelets worksheet, students solve 7 various problems that include working with different wavelets in each. They compute the synthesis given two segments and y, describing what they observe. Then, students plot...
Curated OER
Vibrations and Waves
In this vibrations and waves activity, students determine the period and frequency of a pendulum with the mass of .100 kg released. Then they determine whether the amounts increase, decrease, or stay the same when the same pendulum is...
Curated OER
Waves Velocity & Particle Velocity
In this physics learning exercise, students examine a single wave pulse which travels down a slinky. Then they sketch a single ring of the slinky as the wave goes by and determine whether the wave is constant or not.

Hold Off on the Headphones
Learners determine that waves carry energy and information from one place to another. They determine that wavelength, frequency and wave speed are related and describe that sound is a longitudinal wave whose speed depends on the...

"Why Is the Sky Blue?"
Learners investigate why the sky is blue and the sunset is red. They are asked why do you think that we see the sky as blue? Students write a hypothesis on their "Blue Sky Lab Sheet". They explain why they think that the sky is blue...
Curated OER
Sound Box
Students make simple observations and identify relevant variables, such as frequency and diameter. They then discuss the relationship between variables. The task assesses students' abilities to make simple observations and make...
Curated OER
Wave Equations
Students manipulate a model of a wave in order to solve the wave equation in 1 dimension. By using a model of a wave on a string the student is able to change the tension, length, and mass of the string as well as fix either end of the...
Curated OER
TE Activity: Pitch and Frequency
Students experiment with a vibrating ruler and a kazoo to study the different pitches and frequencies they produce. They create both high and low pitch sound waves. They examine how engineers use sound energy when designing electronic...
Curated OER
Wind Chimes
Students construct wind chimes using physics. In small groups they design and create wind chimes using a specific weights, number of notes, and keeping the cost under ten dollars.
Curated OER
The Cigar Box Guitar
Students correlate string tension with sound pitch. They describe how string mass (thickness) effects sound pitch and demonstrate an understanding of the physics of the acoustic guitar. They see that sound is produced by vibrations.
Curated OER
Making Sound All Around
Fourth graders examine how sound waves are effected by frequency and pitch. They conduct experiments using tuning forks, rubber bands, balloons, and water, and answer questions about the experiments.
Curated OER
Pendulum Problems
Ninth graders explore how pendulums function. In this pendulums lesson students complete a pendulum lab activity.
Curated OER
Making Music
Students learn about sound frequency. In this sound lesson plan, students are introduced to sound frequency and how musical sounds depend on sound frequency.
Curated OER
Measuring the Speed of a Wave
Students create an experiment in which they measure the speed of a wave and record the data in a graph. They work in small groups to write the procedure for the experiment and share it with another group for cross checking of the...
Curated OER
Sizing Up Sound
Sixth graders are introduced to the concepts of sound waves and frequency. As a class, they listen to the differences between different types of instruments. To end the lesson, they practice identifying low and high pitches and playing...
Curated OER
Frequency vs. Size
Young scholars identify and interpret sound as a vibration and what period and frequency are. They also divide the various types of objects so that all objects are explored and the procedures are determined by the students.
Finally,...

A Pocketful of Change
Students study the meaning, symbolism, and value of U.S. coins,
especially the quarter. They conduct a survey of coins in students'
possession, graphing the results to show frequency distribution and drawing
inferences about the U.S....
Curated OER
Pitch
Second graders investigate the concept of pitch and how it can be changed in its duration and frequency. They use rubber bands and cardboard to demonstrate different sound patterns. Students are asked to recognize how vibration varies...
Curated OER
Good Vibrations
Students demonstrate sound waves and make changes in the waves
resulting in changes in pitch. Students associate changes in pitch in various "musical instruments"with size and shape and the sound waves they produce.
