This program introduces students to the general characteristics of rocks and discusses the components of rock classification. On-location footage from throughout North America vividly depicts characteristics and origins of the three major rock types: igneous rocks, sedimentary rocks, and metamorphic rocks.

This video program investigates some of the key elements responsible for weather formation. Different types of air masses and their origins are investigated, as are the formation of weather fronts. Specific weather phenomenon including tornados, hurricanes, and thunderstorms are illustrated in detail.

This program explores the various properties of magnets and the characteristics of magnetic force. Colorful graphics and real-life footage explain how magnets are used in generating electricity. Electromagnets and their many uses are demonstrated as well. Other terminology includes: magnetic poles, magnetic field, electric motor, generator, solenoid, and electromagnetism.

This video explores the fundamental concepts of electrical energy. Easy-to-understand animations illustrate the concepts of electric charge and electric current. Examples of ways we use electricity are cited. Static electricity and the role it plays in creating lightning is also described.

Characteristics enabling organisms to survive and reproduce are referred to as adaptations. This program explores the wide range of adaptations humans, plants, animals, and all living things exhibit.

This program begins by exploring electric current and the role it plays in electrical circuits. The various parts of an electrical circuit are described. Parallel circuits and series circuits are compared. The program concludes by demonstrating some fundamental concepts of electrical safety.

This colorful, exciting program explores the fascinating world of invertebrate animals. Live-action footage conveys basic features of the major invertebrate groups. Special attention is paid to the body structure and physical features of simple animals.

The planets closest to the sun, often referred to as the inner planets, are the focus of this fascinating program. Colorful animations, along with images captured by space probes, illustrate the characteristics of Mercury, Venus, Earth, and Mars. The fundamental structure of the solar system and the process by which planets revolve around the sun are discussed.

Earth's landscape is made up of a wide variety of physical features referred to as landforms. Characteristics of the major landforms are illustrated through the use of dramatic footage from North America, including the Grand Canyon, Interior Plains, and the Rocky Mountains. Earth's water features are also depicted.

What are the characteristics and needs of living things? This question is addressed through live-action footage shot at exciting locations, such as the Galapagos Islands, Canadian Rockies, Mojave Desert, and Florida Everglades. The program begins by discussing the basic characteristics common to living things.

There are millions of different types of animals on Earth, ranging from simple animals, such as sponges and worms, to more complex animals. This program explores complex animals, specifically the major vertebrate groups: fishes, amphibians, reptiles, birds, and mammals. Crisp, exciting video footage portrays the major characteristics of each vertebrate group.

Living things go through changes in the course of their lives, referred to as life cycles. This program takes a look at the life cycles of living organisms, specifically focusing on plants and animals. Exciting video footage and colorful animations illustrate how living things change as their lives progress.

This program covers the major characteristics of minerals, while exploring the roles minerals play in our lives. Crystal structures, which make up minerals, are illustrated, as are examples of the wide range of minerals. Live-action footage from around the world demonstrates the processes by which minerals form.

This program illustrates the everyday, real-life processes of weathering and erosion. Easy-to-understand examples of weathering help students differentiate between the processes of mechanical and chemical weathering. Vivid footage of processes such as freezing, thawing, condensation, and rusting help students grasp how weathering works.

This program introduces students to some of the fundamentals of weather including air pressure, wind, and moisture. The basic principles of cloud formation and precipitation are explored. Important terminology includes: heat energy, atmosphere, troposphere, sun, local winds, global winds, humidity, water vapor, evaporation, condensation, and precipitation.
