- Activity: Engage students with a brief discussion on how they experience sound in their environment (e.g., music, voices).
2. Pitch and Volume (15 minutes)
- Discussion: Explain pitch (high/low sounds) as determined by the frequency of vibrations and volume (loud/soft) as determined by the amplitude of sound waves.

Teacher Reference Guide
This guide provides all the information needed to teach the Properties of Sound lesson to elementary students. The lesson explores how sound is created, how it travels, and how it interacts with different materials. The instructional video and online escape room will be used for engagement and assessment.
Introduction to Sound
Sound is a form of energy created by vibrations. When an object vibrates, it causes the surrounding air particles to move, creating sound waves that travel through various mediums such as air, solids, and liquids. In air, sound waves move faster than they do in gases but slower than they do in solids. This is because the particles in solids are closer together, allowing vibrations to pass through more efficiently. Students should understand that vibrations are the source of all sounds, and these vibrations cause sound waves to move through different materials. The instructional video will visually show examples of how sound waves travel, and this concept will be explored through discussions about common sources of vibrations like musical instruments or voices.
Pitch and Volume
Pitch refers to how high or low a sound is and is determined by the frequency of the sound waves. High-pitched sounds have high frequencies, meaning the sound waves vibrate quickly. Low-pitched sounds have low frequencies, with slower vibrations. Volume, on the other hand, is the loudness or softness of a sound and is determined by the amplitude of the sound waves. The larger the amplitude, the louder the sound. Students should understand that pitch and volume are independent properties; a sound can be high-pitched and quiet or low-pitched and loud. The video will provide visual demonstrations of instruments changing pitch by adjusting the length and tension of strings or air columns, as well as showing how sound waves vary in amplitude. Discuss how students might experience different pitches and volumes in their environment, such as the difference between a whisper and a shout or a deep drum versus a high-pitched whistle.
Reflection, Absorption, and Transmission of Sound
Sound waves behave differently when they encounter various materials. When sound waves hit a hard, smooth surface, they reflect, creating an echo. In places with many reflective surfaces, like an empty room or canyon, echoes can be heard clearly. On the other hand, when sound waves hit soft, porous materials like curtains, foam panels, or books, they are absorbed, which reduces the intensity of the sound and prevents echoes. Transmission of sound depends on the material it passes through; for example, sound travels faster and clearer through solids than through gases like air. Students should be able to explain how these concepts apply in real-life scenarios. For instance, in recording studios, foam panels are used to absorb sound and reduce echoes, creating a controlled sound environment. The video will provide examples of how sound reflects off different surfaces or is absorbed by materials.
Engagement and Assessment
Students will apply their understanding through the online escape room, Properties of Sound: Echoes of the Haunted Manor, where they navigate sound-based challenges. The escape room offers an engaging way to test their knowledge on vibrations, pitch and volume, and sound interactions with materials. Students will use the information learned in the video and discussions to solve puzzles that mirror real-life scenarios. A downloadable worksheet is also available if further assessment is needed, featuring questions and diagrams to reinforce the concepts covered.
