Grades 7-12; Teacher's Guide available online
Physics traditionally has been a difficult subject to master, but this series makes its complexities not only understandable and enjoyable for students but also relevant to their own lives. They illuminate physical processes and show students how these relate to their future careers, stimulate independent and group study, and promote further research.

101. What is Electricity? Presents an overview of naturally occurring electricity found in nature and the role of matter and atoms in electrical charges. Shows how charged atomic particles come to provide electricity and how electric currents are created, transported, and used.

102. The Sun Reveals how everything that exists is a form of energy. Discusses sources of kinetic, chemical, and nuclear energy and the conversion and transport of energy produced from these sources. Provides an overview of the use of nonrenewable sources (such as fossil fuels) and renewable sources (such as the sun).

103. Gravity Describes the role of gravity in simple, everyday mechanical operations, as well as in providing balance to our universe. Explores the interaction of gravity with other forces and shows how various forces cause motion.

104. What is Light? Explains that light is only one of many forms of electromagnetic radiation. Demonstrates how white light imbues objects with shape and color, making them visible. Analyzes various sources of light and how light moves from them.

105. Motion Describes what movement means and how everything, no matter how stationary in appearance, is actually moving. Illustrates and explores varieties of trajectory, as well as velocity. Examines the influence of mass and gravity on motion.

106. Nuclear Forces Begins with an overview of the relationship between matter, elements, and atoms, as well as the structure of the atom. Explores fission and fusion processes and explains how these provide the energy for life on Earth.
