You should be able to see the difference in the movement of the string in the two trials. Do they move? PDF Interesting and inexpensive experiments for high school physics. Can sound waves themselves cause dizziness? Smooth, hard surfaces can deflect noise away from the subject, instead of helping to build energy. Tutorial: Where are marine animals likely to be located relative to the source? After watching a demonstration (video available) of Ruben's Tube (a standing wave flame tube) that uses flame to visualize sound waves, students discuss noise levels and the decibel (dB) range of familiar sounds and environments, including the classroom. to conduct an experiment for kids making sun sensitive fabrics. Monday Friday For this experiment, youll need a decibel meter to measure the levels of different sounds.
