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. They will see why light bends in a medium, how to determine the size of the sun, and how gravity works, as they practice the experiments. As hands-on learning tools, experiments are not only educational, they're fun, too.
