What is sound?

Author: 
Sharon Kessler, ASU Fellow; & Trina Howard, Teacher, Lowell Elementary School
Grade Level: 
5th - 6th (but this lesson would also work well for 7th-12th)
Standards
National Science Education Standards: 
Abilities to do scientific inquiry; Understandings about scientific inquiry; Structure and function in living systems; Regulation and behavior; Diversity and adaptations of organisms.
Arizona State Science Education Standards: 
FIFTH GRADE: STRAND 1 – Inquiry Process Concepts 1-4: Students will engage in the scientific inquiry process by forming and testing a hypothesis, analyzing their data, drawing conclusions, and communicating their results. STRAND 2 – History and Nature of Science Concept 2: Students will experience how technology can facilitate the creation of novel inquiries and data. Students will collaborate with class members while recording and measuring sounds. STRAND 3 – Science in Personal and Social Perspectives Concept 2: Students will use technology (computers, sound analysis software) to conduct their analyses and see the close relationship between scientific knowledge and technological capabilities. STRAND 4 – Life Science: Students will examine the relationship between structure and function in the vocal apparatus of animals, including how the structure of the respiratory system and vocal cords facilitate vibrations which produce sound. STRAND 5 – Physical Science Concept 2: Students will understand the relationship of force and motion as it pertains to the production of sound waves and the propagation of sound waves through various media including air, water, and solids (wood). SIXTH GRADE: STRAND 1 – Inquiry Process Concepts 1-4: Students will engage in the scientific inquiry process by forming and testing a hypothesis, analyzing their data, drawing conclusions, and communicating their results. STRAND 2 – History and Nature of Science Concepts 1-2: Students will experience how technological advances (sound analysis) can make new scientific questions possible. Students will gain skills in observing, questioning, communicating, comparing, measuring, classifying, predicting, organizing data, inferring, generating hypotheses, and identifying variables. STRAND 4 – Life Science: Students will explain how the vocal apparatus and respiratory systems work together to facilitate sound production. Students will be introduced to a variety of ways that different animals make sounds. They will research and compare several animals leading to insights about the animals’ anatomy, habitats, diets, etc. STRAND 5 – Physical Science Concept 3: Students will learn how sound energy propagates through various media (air, water, solids) in waves.
overview: 
Students will learn about how vibrations produce sound, and then they will apply that knowledge to our own vocal tract as they measure their own voices, measure the calls of several other animals, and generate and test hypotheses about sounds across species.
