Exploring Sound Energy
Two Sessions:
Objective: Students will understand that sound is produced by vibrations.

Assessment: Students will create a simple musical instrument using household items and demonstrate how vibrations create sound. https://zinginstruments.com/homemade-musical-instruments/
Key Points:
- Sounds are vibrations. https://www.youtube.com/watch?v=AGjxfx8sy6s
- Vibrations can be felt and heard. https://www.youtube.com/watch?v=BFWLb_MKyRE
- Different objects produce different sounds. https://www.youtube.com/watch?v=pY4YHLQ_ksw
Two Sessions:
Objective: Students will explore how sound can travel through different materials. https://www.youtube.com/watch?v=AxNdr0Bcx20
Assessment: Students will conduct an experiment to investigate how sound travels through solids, liquids, and gases.
Key Points:
- Sound travels through air, water, and solids. https://www.bbc.co.uk/teach/class-clips-video/science-ks1-how-does-sound-travel/z4yrcqt
- Sound travels fastest through solids. https://www.youtube.com/watch?v=AxNdr0Bcx20
- Sound travels slower through liquids and gases.
Session 5:
Objective: Students will learn about pitch and how it relates to sound energy.
Assessment: Students will participate in a pitch matching activity where they will match different sounds to their corresponding pitches.
Key Points:
- Pitch is how high or low a sound is. (pitch means "TONO") https://youtu.be/b3dVsKHwvIs
- Higher pitch sounds have faster vibrations.
- Lower pitch sounds have slower vibrations.
Session 6:
Objective: Students will explore loudness as a characteristic of sound energy.
What is loudness.- https://youtu.be/-zOCOEnlt5Y
Assessment:
Key Points:
- Loudness is how soft or loud a sound is.
- The loudness of a sound depends on the amplitude of its vibrations.
- Louder sounds have larger vibrations.
Review.- final session:
Objective: Students will review and summarize their understanding of sound energy.
Assessment: Students will create a mini-booklet or poster summarizing the key concepts learned throughout the unit.
Key Points:
- Sound is produced by vibrations.
- Sound can travel through different materials.
- Pitch refers to the highness or lowness of a sound.
- Loudness refers to the softness or loudness of a sound.
Project Activities Suggestions:
1. Sound Energy Scavenger Hunt: Students can participate in a "scavenger hunt" in their community to identify different sources of sound energy and explain how they relate to the concepts learned in the unit.
2. Sound Energy Reflections: Students can write a reflection piece where they share their personal experiences with sound energy, such as their favorite musical instrument or a memorable sound they have heard.
