Scientist at Work

During fourth grade’s sound lab, I demonstrated how my phone’s speaker could be amplified by placing the phone in a cup, as well as how to construct a DIY speaker for a phone. This scientist went home and made her own!

Does the size or material of the cups impact the volume and quality of sound? Does the length or material of the tube change your results?
