Carolina STEM Challenge®: Sound Off Kit

Grades 6–12. Design teams must get creative to get loud as they transform cardboard tubes and items commonly found at home or school into a nonelectrical device to amplify smartphone sound. Engage and excite students as they explore how sound waves are transmitted, reflected, and amplified by different shapes and materials. Teams modify designs and then compete to produce the best device to increase the volume and clarity of music or tones. Materials support 15 design teams.
