Recycled Materials Make Music - 7th Grade Science Acoustics Lesson

The 7th-graders had a lesson on acoustics last week when their Science teacher, Mr. Hamilton, shared with them how a stringed instrument works. In particular, his own violin, which he played for the class. They learned about the importance of the bridge, the f-holes, and the taught strings. Then they set about making their own instrument prototypes, using inspiration from the Recycled Orchestra - Cateura, Paraguay.

In two class periods, they experimented with cereal boxes, cardboard scraps, rubber-bands and other materials found around the EurekaLab. The results had to be a stringed instrument with strings that could change pitch.
