Why can we smell aromatic and cyclic compounds and why they are in rings instead of lines? Viewers learn about organic compounds, resonance, naming standards for aromatic compounds, common chemical reactions, and the many uses...

Does your lesson plan for wave properties have its ups and downs? Get some fresh ideas from an informative video! The narrator discusses PS4A, showing the must-know ideas for each grade level through concept maps and demonstrations.

Prove your textbook wrong! A detailed video lesson debunks a traditional explanation for the collapse of a bridge in Tacoma in the 1940s. The narrator outlines why resonance is not the culprit and explains the concept of...

Transforming a deep breath into beautiful musical notes, brass instruments represent an interesting combination of scientific understanding and artistic creativity. Traveling from the mouth piece to the bell, this short...

There are few natural phenomena as startling as an earthquake, and depending on the building you're in, these experiences can be downright terrifying. Follow along as this video explores the factors that determine how a building...

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...

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.

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!

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...

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,...

In this video adapted from the Encyclopedia of Physics Demonstrations, students will learn how a glass beaker vibrates at a specific frequency and how resonance can force it to shatter. [1:34]

A video exploring standing waves. [14:18]

A video exploring the groups that donate electrons to aromatic rings. Video will show examples of these groups, Ortho-Para directors. [12:58]

Hank discusses aromatics and cyclic compounds and naming their substituents, resonance as well as common reactions, and uses. [9:50]

An exploration of resonance in benzene and the carbonate ion.

This tutorial helps learners understand the energy and external forces driving vibrating systems. [11:51]
