This lesson explores the fundamentals of sound, highlighting how vibrations create sound waves that spread through different mediums such as solids, liquids, and gases. Students will learn about key concepts including compression, rarefaction, and how string thickness affects pitch. The interaction between vibrating objects and surrounding molecules will be examined, offering insights into how sound is produced and perceived. By engaging with these core ideas, students will gain a deeper understanding of the science of sound.

Sound Thomas Mrs. Branin 5th Grade
What makes sound? Vibration- a object going back and forth Sound waves- a motion that spreads that spreads away from a vibrating objects
What makes sound Compression- A part of a sound wave where molecules are tightly packed together Rarefaction- the part of a sound wave where molecules are spread away from one another
What can sound go through Solids – Tabletop Liquids - water Gases- air
How sound is Produced by strings The thinner the string the faster it vibrates and produces a higher sound and a thicker string vibrates slower and produces a lower sound. The strings make a pitch
