"Why Is the Sky Blue?"
Students 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...

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.

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 instructional activity, they practice identifying low and high...
Curated OER
Frequency vs. Size
High schoolers 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
Young scholars 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...
