## Common Properties of Matter: Atoms, Elements, and States (2003)

Icon:

Two students in search of ideas for a science project find help in a store like one theyve never seen. Miss Dallerwag, the store owner, helps explain concepts like atoms and molecules. She also describes what mass, volume, and density are and how they are different, and the states of matter and how they change.

## Getting to Know Energy (2000)

Icon:

Energy is all around you. Learn about the many different types of energy and how energy can change form. Vivid examples illustrate how potential energy and kinetic energy are defined, and how one form of energy can change into another. Discover that energy never goes away, that it can only be transferred from one form into another.

## Getting to Know Gravity (2000)

Icon:

Students learn about gravity. First stop: Earthto discover how gravity affects people and things on this planet. Next stop: outer spaceto learn how gravity affects other planets. This learning journey demonstrates the effects of mass on gravity and the difference between mass and weight in a way that is easy to understand and fun to watch.

## Laws of Motion (1999)

Icon:

Isaac Newton himself shows students how gravity, friction, and inertia are related to mass, force, and momentum. Exciting graphics and re-creations allow students to see how Newton's laws of motion relate to real life. Experiments with roller blades, baseballs, and other common objects encourage students to make science exploration recreational.

## Light (2001)

Icon:

Why does light behave the way it does? How does it travel from its source to the objects it illuminates and then to human eyes? Most people certainly take light for granted, but understanding the basic nature of light can open up a whole new world! Students learn how light travels in waves as well as how those waves behave. And children discover the connection between light and color.
