This work offers 60 experiments aligned with national science standards "in content and in processing skills." The text, printed on sturdy cardboard pages and arranged in a three-ring binder for easy photocopying, begins with a comprehensive presentation on safety precautions. The entries are arranged under six subject areas: "Earth Science," "Weather," "Animals," "Plants," "Ecology," and "Environmental Science," and include experiments determining the effects of detergents on plant growth, simulating an archaeological dig, measuring the impact of phosphates on aquatic life, and observing a food web. Each activity begins with an introduction, mention of the time needed to complete the experiment, a list of required materials, any specific safety indications, and a symbol showing the level of difficulty. Many experiments are complemented by simple line drawings. The clear, concise directions are given in numbered steps and are followed by questions prompting students to observe various phenomena. Back matter includes a "Supervision" section, noting the activities that require adult guidance, followed by a section grouping them by their appropriateness for a school laboratory, home, or outdoors. "Our Findings" presents ideas for class discussion, notes to teachers, and answers to the questions posed after each experiment. Both public and school libraries will be well served by this title.
