Gardner, Robert

Contains instructions for seventeen science experiments that explore concepts of volume, most of which can be done with simple materials, and includes notes on how to use some of the experiments as the basis for a science project.

Contains over 210 alphabetically arranged entries that provide information about advances in the technologies of human communication, exploring topics such as the abacus, E-mail, hieroglyphics, and virtual reality, and discussing the lives of key people in the development of technology.

Introduces techniques of criminal investigation, including fingerprint and voice pattern examination, handwriting analysis, and ballistics, and discusses the development of forensic science.

Describes over twenty science projects and experiments designed to explore the effect of exercise and physical conditioning on the human body.

Provides suggestions and directions for science fair projects that use magic tricks and toys to present and explain concepts in chemistry and physics.

Presents facts about animal behavior and includes related experiments, projects, and activities.

Explains the physics principles at work in simple machines and presents science projects involving first-, second-, and third-class levers; the wheel and axle; wheels, bearings, and friction; inclined planes; the wedge; the screw or bolt; and single pulleys.

Presents several forensic science experiments using forgery detection skills, and includes science project ideas and crimes to solve.

Contains science projects and experiments that deal with heredity; each with a materials list, and explanation of the basic theories behind the experiment, and suggestions for further study.

Contains science projects and experiments that deal with the senses; each project includes materials lists, explanations of the experiments basic theories, and suggestions for further study.
