Marianne Berkes has a gift for making science fun, and this book is exhibit A. Mother sun and her "family" of planets spin, roll, tilt, blow and whirl around the Sun to the tune of Over in the Meadow. Each of those actions is astronomically correct. For example, Earth is the one that tilts, and that is what creates the seasons. It is also astronomically up-to-date, with Pluto being a dwarf planet. Bright illustrations create an exciting mood, and there is plenty of interesting supplementary information in the back along with tips on related ways to integrate science, art, and literature in the classroom.

Real-life crime dramas on television intrigue us with the details of postmortem examinations leading to the arrest of murder suspects, but how do forensic pathologists, the doctors who investigate unnatural deaths and chilling crime scenes, actually bring criminals to justice? The story lies in the body of evidence. Literally. The human body provides a wealth of scientific evidence that allows forensic pathology, or legal medicine, to help resolve criminal cases and convict even most elusive perpetrators. The human body records the story of a crime in the language of cuts, wounds, and bruises, and in the fingerprints and bloodstains. Forensic pathologists are trained to scrutinize and interpret this evidence in ways no other scientist can. Examining victims remains from the outside in, forensic pathologists investigate every inch of the human landscape to discover when, how, and why the victim died. Sometimes, a time of death is all a jury needs to convict a suspect of murder, and forensic pathologists are experts at uncovering this crucial evidence. Visiting crime scenes, collecting bodies in the middle of the night, and excavating suspicious burial grounds are all in a days work for the sake of bringing justice to victims who can no longer speak for themselves.
Who committed the crime? When? Even the smallest of witnesses can tell scientists stories that will make or break a criminal case. Insects and pollen grains help forensic scientists bring criminals to justice. A suspect escapes a crime scene, leaving not a trace of evidence behind - except for the hind leg of a grasshopper, which helps convict him of murder. A thief runs through a cornfield, relieved that no one saw him commit the crime - unaware of the tiny grains of pollen stuck to his shirt. Plants and insects hold clues to guilt or innocence. Evidence from nature is all around us, silently and swiftly leaving fingerprints, unnoticed by even the most cunning of criminals.
