Comprehensive kit consists of five hands-on experiments to explore the properties of waves and sound.
- Using springs, students study longitudinal and transverse waves and learn about frequency, amplitude and period.
- Observing the motion of three waves traveling at the same speed, students see how wavelength and frequency are related.
- Using simulated point-source circles of different “wavelengths,” students investigate constructive and destructive wave interference patterns.
- Experimenting with a telescoping resonance tube and tuning forks, students determine the speed of sound in air.
- Using a variety of solid rods and tubes, students examine the variables that affect resonance frequency and rotate the “singing rod” to observe and understand the Doppler effect.
Easy-to-set-up lab stations allow groups to investigate specific aspects of waves and sound then move on to the next station. Detailed instructions, Teacher Notes and all the necessary materials are provided.
