Friedhoffer, Robert

Provides tips on how to create a haunted house at home and instructions for performing magic tricks at a Halloween party.

Explores such topics in physics as levers, friction, heat transmission, and density with experiments using common household utensils.

A guide to simple science fair project experiments for grades three through five. Features experiments on gravity, energy, light, friction, and motion. Each experiment includes background information, an experimental question, materials, step-by-step instructions, results, and conclusions.

Explores such topics in physics as levers, friction, heat transmission, and density with experiments using common household utensils.

Experiments, magic tricks, and other activities explore the scientific principles of matter and energy.

Presents a variety of experiments using items you can buy in the supermarket. Also explains the scientific basis for such things as the flexible plastic strips that cover doorways leading into the meat departments in many large markets.

Presents more than thirty experiments for grades five through seven on such subjects as botany, centripetal and centrifugal force, electromagnetism, the color spectrum, and resonance.

Presents several magic tricks that demonstrate principles of mathematics, biology, chemistry, and physics.

Explores such topics in physics as the properties of water, transmission of heat, evaporation, and air pressure as seen in home plumbing, refrigerators, and other common items.
