Typical Conceptual Questions for Physics I - Waves, Electricity, and Magnetism
This wave and electromagnetism assignment is so thorough, it could be used as a unit exam. The first section of it covers wave concepts. The next section addresses static electricity. There is a section that deals with electric circuits....
Exploratorium
Straw Oboe
Trim the end of a straw to construct a vibrating wind instrument. Everyone in your class can make their own during a lesson on sound waves.
Curated OER
Wave Practice Problems
Physics scholars list the properties of waves and calculate the speed, wavelength, and frequency of waves. The activity is concise, but covers a variety of wave computational skills. The formatting is neat, but it does have small margins...
Curated OER
Communication Delay
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...

How We Hear
Students study how sounds are transmitted from the environment to the brain. In this investigative lesson students participate in activities that show them how we hear, what sound waves are and the difference in seeing and feeling sound...
Curated OER
Waves
In this wave learning exercise, students will review the characteristics of waves which includes the parts of a wave, how waves are measured, and how waves are created. This learning exercise has 8 vocabulary used in a word puzzle, 5...

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
Lesson 3-Explore/Explain Do You Hear What I Hear?
Students explore how loudness is measured. They identify the decibel scale and explain the amplitude of the sound wave.
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.

Sounds Good To Me - Instrument Creation
Third graders differentiate between pitch and volume and explain how sound travels through different materials. They analyze sound waves for their basic characteristics. Students design an instrument based on the principles of sound...
Curated OER
Musical Mysteries
Students examine the changes that occur to sound as the pressure changes. Echoes and sound changes in caves and tunnels are explored in this instructional activity.
