Dixon, Malcolm

Surveys the principles behind the production of light and color. Includes simple experiments.

Describes how man-made structures such as tunnels, bridges, and dams have been built and how they have changed the way we live; and observes the beauty and strength of both man-made and natural structures. Also gives instructions for building one's own structures.

Discusses the development of flight from hot-air balloons, kites, and gliders to the modern jet airplanes and rocket-propelled spacecraft. Includes experiments which explain the principles of flight.

Examines rivers, canals, and other waterways, including their construction and uses, and suggests activities which simulate some of their features.

Introduces engineering principles used in designing ships and marine structures such as oil rigs and lighthouses. Includes directions for associated models and experiments.

Describes different kinds of plants, the function of their leaves and roots, and how they grow. Includes related activities.

Surveys the structure and function of various parts of the human body, with simple activities to reinforce the information given.

Explains the production of sounds and music and provides simple experiments to illustrate the principles described.

Describes such forces as gravity, magnetism, and friction and ways in which such forces cause or impede movement. Includes simple experiments.

Provides an introduction to how electricity is generated, conducted, and used. Includes simple experiments.
