Summary

It's our planet's most plentiful and precious resource. All living things need it, especially humans -- it's literally in our blood! Water makes our existence possible (in addition to making it more pleasant), and this assembly of imaginative puzzles and experiments reveals the fascinating facts behind water and its characteristic qualities. Where does drinking water come from, and where does it go? Why do icicles from from melting snow? What makes ships float? These and other thought-provoking questions are explored through 21 captivating experiments. Appropriate for students at and above the junior-high level, the puzzles and experiments address condensation and evaporation, melting and boiling points, vaporization, and many other water-related properties. Complete answers for all puzzles appear at the end of the book. Author Robert Gardner taught physical science, physics, chemistry, and biology for more than 30 years at the Salisbury School in Salisbury, Connecticut. The recipient of many awards and citations, he was hailed by School Library Journal as "the master of the science experiment book." This collection of his tried-and-true scientific demonstrations will prove popular both in and out of the classroom. Book jacket.
