Astronomy enthusiasts, science gurus, and all curious minds, are provided nearly two dozen experiments that will certainly garner multiple science-fair awards. Each experiment exhibits clear, safe instructions with descriptive text and detailed photography.

As hands-on learning tools, experiments are not only educational, they're fun, too.
