This standard steel tuning fork, tuned to the note C (261.6 Hz), is an excellent tool for demonstrating the physical nature of sound in physical science classrooms or at home. Simply strike the fork with a mallet and a clear, steady tone will emanate, perfect for a variety of hands-on experiments.

Possible classroom uses include :

• Vibration and sound propagation: observe how the fork’s tines vibrate to produce a sound wave.
• Resonance: hold the vibrating fork near a glass of water or another object to demon.
• Frequency and pitch: compare this fork to others of different frequencies to explore the concept of pitch.
• Sound conduction through different media: touch the vibrating fork to a tabletop or partially submerge it in water to observe how vibrations transmit through solids and liquids.
• Beat frequencies: strike two tuning forks of slightly different frequencies at the same time to hear the acoustic beating effect.

Comes in a convenient plastic pouch for storage and transport, making this tuning fork a great addition to any physical science classroom or home experiment kit.
