Gr 5-8-These introductions include a lot of detailed information, making them useful as resource materials for science projects and reports. Where applicable, the books also include brief discussions of scientists important in the field, the history of the topic, and current and future applications. Occasionally, comparisons to familiar phenomena are used, as when the movement of gas is likened to that of bumper cars. This helps make difficult points clear while still maintaining a scientific tone. The straightforward, no-nonsense narratives and simple design make this series a nice package for basic science.
