Exploring Sound and Vibrations

Miss Frizzle's class is preparing for a concert at the sound museum, but Carlos's instrument sounds odd. During their journey, the bus breaks down, leading them to a haunted museum. Inside, they explore and learn about sound waves and vibrations. Carlos discovers that the appearance of his instrument doesn't matter, but how it vibrates does.
