Explore the science of sound as students investigate vibrations, sound waves, and the shapes that help voices travel. Inspired by inventor James West and the uplifting story Stand Tall, Molly Lou Melon, learners will engineer a model voice amplifier that makes the same spoken phrase easier to hear—without using electricity.

Through playful sound investigations, hands-on engineering, colorful printables, and meaningful discussions, this STEM with Soul lesson strengthens scientific thinking while nurturing Authenticity, Confidence, and Self-Respect.

Who knew a paper tube or cup could give a voice such a boost? Students will discover that thoughtful engineering can make a message louder, while real confidence helps make every voice worth hearing.
