Water Science, Water Fun: Great Things to Do With H2O

Presents basic facts about water and includes simple experiments to illustrate such aspects as surface tension, dispersion, saturation, and buoyancy

Gr 3-5--A hands-on approach to the properties and forms of water. Surface tension, absorption, emulsion, saturation, etc., are each addressed on a single page with a brief explanation of the term followed by the outline for an activity to demonstrate the concept. A large, full-color drawing and a description of the expected result accompany each demonstration. In a few instances, however, both the explanation and the activity are too brief and oversimplified to be effective. A short but helpful index is included and, in most cases, difficult words are defined within the text. Both the introduction, which explains the history of the world in a few paragraphs, and a page on water safety at the back of the book, seem unnecessary. Nonetheless, this is an adequate addition for libraries looking for simple science demonstrations.
