Resonance
First, Sal compares a benzene ring to cyclohexane. He introduces the concept of resonance and uses Lewis structures to demonstrate that there is an electron cloud surrounding the entire benzene ring, rather than a "flip-flopping" between...

Simple Harmonic Motion
This short video covers simple harmonic motion, focusing on pendulums. It is the fifth in a series of six videos that make for a nice Physics review.
Curated OER
Breaking a Wine Glass Using Resonance
This is just a short video of a wine glass breaking due to resonance. You could embed it into a PowerPoint or Smart Board lesson on sound. It is rather remarkable that this can be done purely with sound!
Curated OER
STEMbite: Physics of a Toy Piano
Examine how the length of an object affects the resonant frequency of the sound wavelength when struck, resulting in a different pitch. Observe this occurrence in a toddler's xylophone, two kitchen pot lids, and a plastic straw. The...

STEMbite: Standing Waves
The casual voice of the filmmaker explains standing waves using a linked chain bordering a neighborhood parking lot, a bucket of blue-colored water, and a rope tied to a fan blade. He uses the appropriate vocabulary (frequency,...
