Here comes the sound. After watching a couple videos demonstrating and explaining the Doppler Effect, learners develop their own understanding of the phenomenon. Scholars draw a sound wave and observe how the perception of the wave...

No need for a knife when a fork will do! Groups of pupils first read about the science of sound, and then experiment with tuning forks. Teams gather information about the pitch and length of their forks and compare them to...

String together how instruments produce sound. Using pieces of string, learners find ways to create sound. They investigate changes to the string and the effect of adding a cup. Finally, pupils experiment by changing the way to create...

Be an octave above the rest. A musician explains how to write music in different time signatures. An interesting resource continues to demonstrate ratios using the pitch of musical notes and hertz. Pupils use a pitch table and determine...

The star of the show is ratios. The informative resource explains how to transpose music using ratios. Individuals transpose the song "Twinkle, Twinkle" in the activity by applying their ratio skills. The activity challenges class...

The calculator has an interesting way of displaying numbers in scientific notation, but don't let that confuse your pupils! A lesson designed to give learners practice with scientific notation and calculators provides several practice...

Reinforce the concept of probability with a series of lessons highlighting the idea of likelihood, probability formulas, relative frequency, outcomes, and event predictions. The collection is made up of four lessons offering informative...

Pitch is the ear's response to frequency, and here you can get a better understanding of pitch, its measurement and the perception of pitch.

This online exploration provides an opportunity to identify the different properties of waves and the relationship that exists between energy, wavelength, and frequency. Correlate images from the Hubble Telescope to the wavelength,...

[Free Registration/Login may be required to access all resource tools.] Students solve problems dealing with simple harmonic motion using a mass on a string.

This hypertext physics course page illustrates and explains the Doppler effect. Users perform practice calculations for frequency shifts using the Doppler equation.

An indexing page for an elaborate and in-depth hyper-textbook on various physics topics. This page indexes several others which pertain to human ability to perceive sound and recognize pitch. Introduces and explains Place Theory.

Online physics lab experiment in which students use resonating waves inside of a closed-end air column to determine the speed of sound. The form allows students to check their answers and receive immediate feedback.

A series of graphics, downloadable animations and text describe and explain the motion of a pendulum. Some sections require an understanding of calculus.

[Free Registration/Login may be required to access all resource tools.] Combine calculations for amplitude and period on a sine or cosine graph.

[Free Registration/Login may be required to access all resource tools.] Relating period and frequency for a sine or cosine graph with examples, practice problems, and vocabulary.

Explains how to create a stem-and-leaf plot from a data set. Demonstrates how to format a clear stem-and-leaf plot.
