Physical Properties of Water
This video is accompanied by text: "... focus on its physical properties. These include cohesion, adhesion, surface tension, and specific heat. Since the first three are closely related, we'll discuss them together.
Cohesion is the attractive force between similar molecules in the same phase. Water's hydrogen bonds are largely responsible for its cohesion. Cohesion can be thought of as the sum of all the hydrogen bonds in a collection of water molecules. Cohesion has important biological c
Water and Life: Summary
This video is accompanied by text: "Most of water's chemical and physical properties can be traced to its polar structure. This means it has an uneven distribution of electron density. One important implication of the polarity of water is its ability to dissolve ionic compounds and small polar molecules. Water molecules surround the ions or molecules as they dissociate from the crystal. In this example, the more positive end of the water molecule is oriented toward the negative chloride ion, and
Water The special chemical properties of water are explored, along with the need for its protection and conservation. Water is abundant on our planet, so we take it for granted, but not all water is usable. Water can easily become contaminated by human activity, so chemists are developing ways to clean our water supplies. Ice, water, and steam are used by chemists for a var
Structure of Water
This is a teacher-created, short animation that illustrates the structure of water. English captions appear to explain the images. (03:35) Music by Ben Hammer.
Cornstarch Walk on Water - Cool Science Experiment
This is a three minute video shows how kids can make a walk on water type experiment. For younger folk.
Science Project: How Salt Effects The Density of Water
This video provides a step-by-step demonstration of an experiment of the effects of salt on water density. Using the concepts of density and buoyant forces, the experiment shows what happens when you drop an egg in a cup of water and what happens after salt is added to the water. (6:29)
Water Density and Temperature
This is a short video that demonstrates the difference in density of cold water and warm water. It explains how the waters will mix or not mix according to their density and temperature. This is a good idea for a simple classroom experiment. (1:57)
The Phase Changes of Water Song
This teacher-made video shows a teacher singing about the phase changes of water while holding up the lyrics and diagrams of what he is singing about. The song is set to the tune of "Hey Soul Sister." Some key concepts include phase, state of matter, heat energy, particles, vibrating particles, latent heat of fusion, kinetic energy, melting, boiling point, vaporize, latent heat of vaporization, breaking bonds, and constant.

Ancient Egyptian Mummification: Gods and Godesses
This video features an 11-year-old who is giving a presentation on the details of ancient Egyptian burial and mummification. Basic overviews of godesses and gods of the culture are also included.
Ancient Egyptian Embalmer's Apprentice
A BBC produced simulation in which the student becomes a mummy maker. The animations are basic. The "ick" factor of removing body parts is sure to appeal to middle school students.Â
How to Make a Mummy: Easy Clay Animation
A fun classroom annimated claymation video that shows how an Egyptian Mummy was made. Three minutes of good information in a "friendly" format. The video needs to be accompanied by a worksheet and, perhaps, timeline. Lots of learning possibilities here such as a map of Eqypt and study of human anatomy. Run time 03:29.
Fluids (Part 1)
What a fluid is. Difference between liquids and gasses (both fluids). This video, which is suitable for high school students, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification. Run time 09:46.
Fluids (Part 2)
Pressure and Pascal's Principal. This video, which is suitable for high school students, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification. Run time 10:12.
Fluids (Part 3)
Pressure in a fluid at depth. This video, which is suitable for high school students, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification. Run time 09:54.
Fluids (Part 4)
This video uses our understanding of fluid pressure to figure out the height of a column of mercury. This video, which is suitable for high school students, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification. Run time 10:09.
