4 editions published in 2007 in English and held by 219 WorldCat member libraries worldwide

Collection of computer-animated video shorts exploring the wave model of light
The Special theory of relativity( Visual )

4 editions published in 2007 in English and held by 219 WorldCat member libraries worldwide

This collection of computer-animated video shorts explore Einstein's contributions to the study of light
Geometric optics : refraction( Visual )

4 editions published in 2007 in English and held by 213 WorldCat member libraries worldwide

23 computer-animated video shorts showing the behavior of light as it passes through various physical substances
Geometric optics : reflection( Visual )

4 editions published in 2007 in English and held by 211 WorldCat member libraries worldwide

What does a mirror tell us about light? This cluster of 11 computer-animated video units delves into one aspect of light's behavior-reflection. Euclid's geometric optics and his findings on the perception of distance and perspective lead to a discussion of the Law of Reflection-linking angle of incidence with angle of reflection-and the concepts of absorption, transmission, and diffuse reflection. The principles involved with plane, concave, and convex mirrors are explained, including vertex, principle axis, center of curvature, radius of curvature, and virtual image. A group of "mirror equations" show how an object's location can be determined using the laws of reflection
Metals and ionic solids( Visual )

3 editions published between 1984 and 2005 in English and held by 64 WorldCat member libraries worldwide

Shows the common properties of metal (conductivity and maleability) and explains the types of bonding that occur between metal atoms. The properties of metals, which are covalent solids, are contrasted with those of crystals, which are ionic solids. Animated
Geography skills( Visual )

1 edition published in 1995 in English and held by 58 WorldCat member libraries worldwide

This computer-animated series provides an in-depth examination of the important skills of the geographer
Introducing the players( Visual )

3 editions published between 1984 and 2005 in English and held by 58 WorldCat member libraries worldwide

Introduces the atom and the three main subatomic particles--the electron, the proton, and the neutron. Demonstrates the location, charge, and relative mass of these particles. Reviews Ernest Rutherford's model of the atom in terms of its advances and shortcomings
Conductors and insulators( Visual )

3 editions published between 1986 and 2005 in English and held by 44 WorldCat member libraries worldwide

Establishes some of the fundamental principles of electrostatics, such as negative and positive charges. Illustrations of the electron flow in charged particles at the atomic level show the difference between conductors and insulators
Charging by induction( Visual )

1 edition published in 1992 in English and held by 40 WorldCat member libraries worldwide

Reviews the concepts of charging by contact and discharging by grounding illustrates how a charged rod affects an electroscope. One application of charging by induction is demonstrated with a simulation of the action of lightning during a thunderstorm
Protein synthesis( Visual )

2 editions published between 2003 and 2005 in Spanish and English and held by 35 WorldCat member libraries worldwide

An animated discussion of protein synthesis. Discusses the variety of proteins, DNA, DNA replication, types of RNA, and RNA Transfer
Photosynthesis( Visual )

2 editions published between 1984 and 1992 in English and held by 31 WorldCat member libraries worldwide

Demonstrates how chlorophyll in plants absorbs and transfers captured light energy to other molecules and eventually creates energy storage molecules such as glucose
The meiotic mix( Visual )

1 edition published in 1992 in English and held by 28 WorldCat member libraries worldwide

Explains the difference between mitosis and meiosis. Shows how variations are generated by chromosomes matching during meiosis
The feedback cycle( Visual )

1 edition published in 1992 in English and held by 28 WorldCat member libraries worldwide

Describes the feedback cycle, the ongoing monitoring of homeostasis to inhibit or stimulate the release of hormones. Shows how negative feedback works and the many ways the body responds to messages from receptors
Hormonal control( Visual )

1 edition published in 1992 in English and held by 26 WorldCat member libraries worldwide

This program takes a look at the role played by hormones in maintaining homeostasis, illustrating how hormone production stimulates reactions and, in turn, how hormone production is monitored
Wave-particle duality( Visual )

2 editions published between 1984 and 1992 in English and held by 25 WorldCat member libraries worldwide

Explains the behavior of light from the concepts of the ancient Greeks to the proven wave-particle models of today
Biochemical balances( Visual )

2 editions published between 1984 and 1992 in English and held by 24 WorldCat member libraries worldwide

Introduces the chemical processes of competitive inhibition in the production of enzymes, and the law of mass action: the natural tendency for chemical reactions to act in two directions
Osmoregulation( Visual )

2 editions published between 1984 and 1992 in English and held by 24 WorldCat member libraries worldwide

Explores the process of osmoregulation, using as an example the complex filtering process that takes place in the kidneys
The Sea within( Visual )

2 editions published between 1984 and 1992 in English and held by 24 WorldCat member libraries worldwide

Looks at how body fluids are adjusted and balanced to match internal needs to external conditions. Describes the five mechanisms of homeostasis that control body fluids
The concept of energy flow( Visual )

2 editions published between 1984 and 1992 in English and held by 22 WorldCat member libraries worldwide

Utilizes the second law of thermodynamics to explore the concept of èntropy', using for study purposes a closed system represented by a disabled space shuttle
