Wave Mechanics (Frequency & Amplitude)
Integrated Sciences (Biology, Chemistry, Physics)
Your child can chart a wave profile, mathematically defining its wavelength, frequency, and amplitude, and explaining how sound pitch changes.
In real life
Watching sets roll in at the beach, your child times the swell and estimates its frequency. Later, they tighten a guitar string and explain that shorter, faster waves are exactly why the pitch climbs.
