Understanding Sound: Vibrations, Waves, and How Strings Produce Different Pitches

In this 5th-grade lesson by Mrs. Branin, students explore the concept of sound and how it is produced through vibrations. Discover how the back-and-forth motion of vibrating objects generates sound waves that travel through different mediums, including solids, liquids, and gases. Learn how the pitch of a sound is affected by the length and thickness of strings, as well as the concepts of compression and rarefaction within sound waves. This engaging lesson aims to deepen students' understanding of the fascinating world of sound.

  1. Sound Alyssa Mrs. Branin 5th grade

  2. What Makes Sounds Vibrating- a back- and- forth motion Sound Waves-A vibration that spreads away from a vibrating object

  3. How Sound is Produced By strings When you pluck a shorter guitar string it will make a pitchy sound and if you pluck a long string it makes a lower sound. There are thicker strings and thinner strings if you pluck them they will make a different sound.

  4. What makes sounds Compression- The part of the sound wave where molecules are crowded together Rarefaction- The part of the sound wave where molecules are spread apart

  5. What can sound go though Solids- metal Liquids-ice tea Gases- air
