Every day we use many types of energy to accomplish different tasks. This program uses real-life examples to differentiate between potential and kinetic energy, and to demonstrate different forms of energy, including mechanical, thermal, chemical, electromagnetic, sound, and nuclear energy. Energy conversions and the law of conservation of energy are also discussed.

Just about everything we eat, touch, and see contains organisms too small to be seen with the naked eye. This video explores the fascinating world of microscopic life. It begins by discussing viruses and explaining how these cause disease. Bacterial cells are described, highlighting the important roles they play on Earth.

Bones and muscles, which enable the body to move and carry out its everyday functions, are the focus of this program. Easy-to-understand anatomical animations depict different bones and joints found in the body. The three primary types of muscles – smooth, cardiac, and skeletal – are discussed, with special attention given to their roles within the body.

Maintaining a healthy body is a fundamental part of leading a fulfilling, successful life. This video program highlights many of the basic things everyone can do to maintain a safe and healthy lifestyle.

This video explores the wide range of defense mechanisms the body calls upon to fight foreign invaders in an effort to maintain health. Immune responses, diseases, and care of the immune system are some of the topics addressed.

The fascinating geologic processes of mountain building, seafloor spreading and volcanoes are a few examples of the power of plate tectonics. Footage filmed on-location in Iceland, the Canadian Rockies, and Crater Lake help viewers understand the theory of plate tectonics.

We are all familiar with common examples of mammals such as cats, dogs, and horses. Humans are also mammals. This action-packed program illustrates the common characteristics of mammals while also exploring some of the major mammalian groups.

Almost all life either directly or indirectly depends on one of the most important biological processes on the planet - photosynthesis. Through easy-to-understand graphics and colorful animations, the complex chemical process of photosynthesis is explored. The various structures involved in photosynthesis, transpiration, and transport are also highlighted.

The amazing biological processes of reproduction and development are illustrated in this fast-paced video. Easy-to-understand diagrams, animations, and video footage explain the steps of the life cycle beginning at fertilization.

With every breath you take, the process of respiration is supplying cells in the body with oxygen they need to carry out important processes. This engaging program highlights the major structures and functions of the respiratory system.

The conquest of land by plants and their proliferation is an amazing biologic story. This vivid, colorful video highlights the evolution of plants, while also describing the major groupings of modern-day plants.

Live-action weather footage helps students learn how they can observe the weather. Concepts and terminology: temperature, air pressure, weather systems, precipitation, and wind.
