Waves in a Ripple Tank  
Circular waves, linear waves, and waves from two point sources in a ripple tank are shown and described.
Quantum Chemistry
Waves in a Slinky™  
A Slinky™ is used to demonstrate transverse and longitudinal waves, reflection, energy dissipation, interference, and plane polarization.
Quantum Chemistry
Standing Waves on a String  
The relationship between frequency, wavelength, and energy absorption for waves on a stretched string is discussed.
Quantum Chemistry
Circular Standing Waves in a Ripple Tank  
Circular standing waves in a ripple tank are demonstrated.
Quantum Chemistry
Standing Waves on Chladni Plates  
In these movies we demonstrate two dimensional standing waves on Chladni plates.
Quantum Chemistry
Waves Consisting of Single Pulses  
Characteristics of single pulse waves include direction of displacement and wave speed illustrated in the following slinky demonstrations.
Quantum Chemistry
Standing Waves on a Wave Demonstrator  
The relationship between frequency and wavelength for standing waves on a 0.90 m short-rod wave demonstrator is explored.
Quantum Chemistry
Standing Waves on a String - Separate Movies  
The relationship between frequency and wavelength for standing waves on a stretched string is demonstrated in a series of separate movies.
Quantum Chemistry
Standing Waves on a Wave Demonstrator (with frequency)  
The relationship between frequency and wavelength for standing waves on a 0.90 m short-rod wave demonstrator is explored. The frequency is displayed at the bottom of the screen.

Discovery Videos  Lyubov Hoffman Laroche, Gary Wulfsberg, Barbara Young
The use of digital video for instruction has many advantages. In many situations the only way to present some chemical phenomena is through the use of video. The two video lessons presented here are examples intended to supplement our article in the August 2003 issue of JCE.

Denaturation of Protein by Strong Acid  John W. Moore, Jerrold J. Jacobsen, Gary Trammell, Kristin Johnson
"Strong acid denatures egg white proteins.This video contains voiceover:""The tertiary structure of egg white proteins is held together by hydrogen bonding and hydrophobic interactions. Adding strong acid to the protein disrupts the intermolecular forces, and the tertiary structure is lost. The loss in protein structure is called denaturation. The proteins precipitate, forming a white solid."""

Which Is Hot  John W. Moore, Jerrold J. Jacobsen, Lois M. Browne, John F. Zimmerman
"Two identical test tubes are shown; one is hot, and one is not. This video contains voiceover: Hot glass looks just like cold glass but it can cause severe burns. Be Careful!"
Centrifuging a Sample  John W. Moore, Jerrold J. Jacobsen, Lois M. Browne, John F. Zimmerman
The demonstration on this page shows a technique that should not be used by undergraduate chemistry laboratory. This video shows what happens to sample in a centrifuge while the centrifuge is on, and the result of stopping the centrifuge improperly. A narrative is included in this video: The centrifuging process allows the solvent to completely settle out. The jarring caused by hand braking destroys the distinct separation between supernatant and solid.

Chemistry Comes Alive!  John W. Moore, Jerrold J. Jacobsen
Chemistry truly does come to life through this collection of pictures, animations, and movies depicting chemical reactions and techniques. The Chemistry Comes Alive! collection includes hundreds of high quality QuickTime movies and thousands of still pictures.
ChemPages Laboratory Resources  John W. Moore, Jerrold J. Jacobsen, Joe L. March
The Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory. They have been put together for use as both a pre-laboratory preparation tool and an in-laboratory reference source.
