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.

MS-PS3-3: Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.
MS-PS3-4: Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.
