A collection of ideas for science fairs and extra credit projects includes chemistry, physics and biology-themed activities that can be performed using mainly household items and completed from within a few minutes to over the course of a full day.

Outlines fifty-two kitchen experiments that utilize common pantry items to introduce fundamental concepts in physics, chemistry, and biology.

Presents twenty-seven experiments that explore key areas in technology, including building an electric car, creating reusable rockets, and testing solar power.

"Children love challenges, especially ones that involve hands-on experimentation and friendly competition. Can they build a bridge using only pasta and glue, one that a toy car can drive both under and over, and is sturdy enough to carry a considerable weight? Can they construct a "roller coaster" from recycled cardboard tubes in which the marble "car" jumps a track to land safely at its final destination? And can they create a device to safely catch...

"This bestsellling guide has been expanded and updated, enabling ordinary folks to construct even more exciting ballistic devices in their garage or basement workshops than ever before"--Cover p. [4].

Presents four experiments using plants that demonstrate how plants need and react to sunlight, air, water, and minerals.

Analyzes ten key experiments in the history of science and their implications for human knowledge, ranging from Galileo's measurement of the pull of gravity to Isaac Newton's examination of how light causes vibrations in the retina.

Provides step-by-step instructions for experiments using readily obtainable materials that demonstrate scientific principles related to engineering disasters.
