Teams of high school physics teachers, high school physics students, and physics teaching majors worked together to build apparatus:
Resonance
Atomic Force Microscopy (AFM)
Dr. Merrell Johnson
Model an AFM macroscopically by vibrating a wooden stick at resonance with a magnetic drive. Nuclear Magnetic Resonance (NMR) Model the magnetic splitting of degenerate energy levels and transitions using a small sphere with embedded magnet placed between large permanent magnets and a Helmholtz coil.

Light as Wave
Spectrography
Dr. Timothy Grove
Calibrate using a discharge lamp. Examine Fraunhofer lines, blackbody radiation, absorption spectra of food coloring, and emission spectra of laser excited Playdoh Interferometer.
Interferometer
Dr. Gang Wang
Set it up as a Michelson interferometer or a gravitational wave detector. Measure thermal expansion of metal rods.
Acoustics
Dr. Jacob Millspaw
Acoustic Levitation
Use sound waves to lift matter. Several low cost Piezo buzzers and affordable drivers for the buzzers provide the sound waves.
Ultrasound
Apply the same apparatus to make ultrasound measurements such as range finding. Using multiple sources, one can explore beam shaping through interference.
