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.

Just as some people dig and look for pirate treasure, some scientists dig and look for treasures, too. These treasures may not be gold or jewels but fossils. Following in the footsteps of Dino Tracks, this sequel takes young readers into the field with paleontologists as they uncover treasured clues left by dinosaurs. Readers will follow what and how scientists have learned about dinosaurs: what they ate; how they raised their young; how they slept, fought, or even if they ever got sick. True to fashion, the tale is told through a rhythmic, fun read-aloud that can even be sung to the tune of Itsy Bitsy Spider.
The sense of sight helps an animal stay safe from predators, find food and shelter, defend its territory and care for its young.

Mary HollandLos ojos de los animales pueden ser grandes y redondos, pueden estar separados, o incluso, pueden ser azules. Cada uno de estos rasgos nos dan pistas dentro del mundo animal. Los lectores no sólo investigarán el sentido de la vista pero también cómo los ojos de los animales nos pueden decir en dónde se encuentran en la cadena alimenticia, si es que cazan durante el día o la noche, o la edad. Premiada/Galardonada como fotógrafa de la naturaleza y educadora ambiental Mary Holland comparte una gran variedad de ojos a través de este diario fotográfico.

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.
The famous Lindbergh kidnapping in the 1930s was solved, in part, through a detailed analysis of the kidnapper's handwriting. Other criminal cases, such as selling phony manuscripts, forgery, and fraud can be broken with detailed analyses of handwriting, typewriting, photocopied documents, and the inks and papers used on documents. The science of analyzing documents has been growing for more than a century. In this book, readers will learn how to document analysis has helped solve various crimes, from kidnappings and famous forgeries, to bombings and other violent crimes. Readers will also see how document examiners present their findings in court. Crime leaves a paper trail, and document analysis provides the techniques for following that trail.
The digital age we entered in the twenty-first century has rapidly become an age of digital crime. Cyber crimes like spoofing, phishing, and hacking are on the rise, and computer forensic technicians are on the case. Even traditional crimes like murder, fraud, and child abuse can be both facilitated by computers and solved through computer investigation. Computer Investigation helps readers understand how cyber crimes are committed, and how investigators help solve them and bring the perpetrators to justice. Readers will also gain a few tips for protecting themselves online and protecting their computers from intrusions and hacks.
Most people cringe when they hear the word physics. Physics is a very technical science that most people rely on every day, but do not really care to understand. Things work, and that is enough for most of us. Solving Crimes with Physics delves into the use of this challenging science to give readers a basic understanding of how the principles of physics can be used to solve crimes. From ballistics to bomb blasts, the knowledge of the theories of physics are powerful tools in the hands of a skilled forensic scientist.
Why are programs such as CSI, Law & Order, and Cold Case so popular? Our culture is fascinated with crime, and these television shows reveal investigators’ procedures and secrets. With so many forensic-based television programs, it might seem that North America’s morbid curiosity is a new phenomenon. The truth is, however, that humanity has always been fascinated by that which also frightens them. What’s more, humans are attracted to puzzles, and forensic science offers opportunities to solve mysteries while at the same time catching the bad guys. Modern media has only magnified the tendencies of previous generations. This book takes a look at the ways this fascination with crime shapes modern news media, television programming, movies, and the Internet. It also provides information on the real-life opportunities for forensic careers. Forensic Science is more than just a cultural obsession: it is a fast-growing professional field. Forensics in American culture will reveal this field’s intriguing mixture of science, mystery, excitement, and justice.
A flake of skin, a strand of hair, a fleck of saliva, a drop of blood - everywhere we go we leave behind bits of ourselves that are as unique as fingerprints. Each cell contains genetic material called DNA, which holds information that scientists can use to learn about the person who left those cells behind. In the past twenty-five years, researchers have made significant advances in all disciplines of science, including the study of genetics. As science has leapt forward, the effect on forensics has been remarkable. New knowledge of DNA has dramatically changed the amount of information available to forensic scientists at the scene of a crime, opening doors that were never open before.
