Teaches caveman Zog that people use energy in one of two main ways: by moving heat from one place to another (conduction, convection, or radiation) or by transferring energy from one form to another by using an appliance, like a lamp or car. Appliances always waste some energy, and Zog learns why energy efficient appliances are the best choices people have today. As only a caveman can, Zog provides plenty of laughs along the way to finding clever and complete answers to elementary energy questions.

In this segment, students learn all about different types of energy found on Earth. Solar energy comes from the sun, and geothermal energy is generated and stored in the earth. Students also discuss these forms of energy and how the energy of the earth transfers heat through the convection process. Part of the "Earth Science" series.
This video explores the daily condition of the Earth's atmosphere, and the factors that influence and cause weather. Special emphasis is given to the global processes that generate weather patterns. Other topics covered include conduction, convection, radiation, thermometer, barometer, air pressure, winds, anemometer, sea breeze, land breeze, doldrums, trade winds, prevailing westerlies, polar easterlies, and jet streams.
The transfer of heat is one of the fundamentals of scientific inquiry. Using numerous examples of how heat transfer is used in everyday life, this program takes students on a journey through the mechanisms and practicalities of heat transfer, clearly explaining the mechanisms of conduction, convection, and radiation and introducing the concept of thermal capacity of an object.
Part of the "Active Physical Science" series. Provides an overview of the basic concepts of physical and chemical science. Contains the following sections: (1) "Air Quality," which contains "Test of Two Gasses Using a Glowing Splint," "Combustion in a Car Engine," "Convection," and "Inversion"; (2) "Energy," which contains, "Student Rube Goldberg Machines" and "What Affects a Cart's Kinetic Energy?"; and "How Do Machines Help Build Big Things?"
