Product Details

Listen up! We are constantly exposed to sounds from televisions, radios, traffic and even each other. When present at safe volumes, these sounds don’t affect our hearing, but, if the sounds are too loud or last too long, hearing may be compromised. Students perform tests with a vibrating tuning fork to observe how sound waves travel through air and how they affect liquids and solids. Students even perform the Weber and Rinne tests to analyze their own hearing followed by thought-provoking questions that force them to think about their own auditory health.

Super Value Kit is complete for 5 students. All materials are reusable.

Performance Expectations

MS-PS4-1. Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.
MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
MS-LS1-8. Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories.
HS-PS3-2. Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as a combination of energy associated with the motion of particles (objects) and energy associated with the relative position of particles (objects).
HS-PS4-1. Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media.
HS-LS1-3. Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.
