Students measure the wavelength of sounds and learn basic vocabulary associated with waves. As a class, they brainstorm the difference between two tuning forks and the sounds they produce. Then they come up with a way to measure that difference. Using a pipe in a graduated cylinder filled with water, students measure the wavelength of various tuning forks by finding the height the pipe must be held at to produce the loudest note. After calculating the wavelength and comparing it to the pitch of each tuning fork, students discover the relationship between wavelength and pitch.

It only takes a few notes of Sarah MacLachlan’s “Angel” over images of homeless dogs and cats to trigger our tear ducts. Heartbreaking visuals aside, what makes the song itself so sad? What is it musically about a song that makes it sound sad? Hosts Nahre Sol and LA Buckner hear from experts and break down the components of sad-sounding music, creating their own somber composition.

Learn about Zitkála-Šá, also known as Gertrude Simmons Bonnin, a Yankton Sioux author, composer, and indigenous rights activist in this video from the Unladylike2020 series.

Taken from her community at age 8 to attend a boarding school as part of the assimilationist policy of the U.S. government to educate Native American youth under the motto: "Kill the Indian to save the man," she used her education to advocate for American Indian rights. She trained as a violinist at the New England Conservatory of Music, and in 1913 wrote the libretto for what is considered the first Native American opera, The Sun Dance Opera. As an author, she published in prestigious national magazines such as Harper’s and The Atlantic, writing about American Indian struggles to retain tribal identities amid pressures to assimilate into European American culture.

She joined the Society of American Indians, edited its publication American Indian Magazine, and in 1926 co-founded the National Council of American Indians to lobby for voting rights, sovereignty rights, and the preservation of Native American heritage and ways of life. Support materials include discussion questions, research project ideas, and primary source analysis.
