Take to the sky with Apis, one honeybee, as she embarks on her journey through life! Now available in paperback.An Orbis Pictus Honor BookSelected for the Texas Bluebonnnet Master ListFinalist for the AAAS/Subaru SB&F Prize for Excellence in Science Books A Bulletin of the Center for Children's Books Blue Ribbon BookA tiny honeybee emerges through the wax cap of her cell. Driven to protect and take care of her hive, she cleans the nursery and feeds the larvae and the queen. But is she strong enough to fly? Not yet! Apis builds wax comb to store honey, and transfers pollen from other bees into the storage. She defends the hive from invaders. And finally, she begins her new life as an adventurer. The confining walls of the hive fall away as Apis takes to the air, finally free, in a brilliant double-gatefold illustration where the clear blue sky is full of promise-- and the wings of dozens of honeybees, heading out in search of nectar to bring back to the hive. Eric Rohmann's exquisitely detailed illustrations bring the great outdoors into your hands in this poetically written tribute to the hardworking honeybee. Award-winning author Candace Fleming describes the life cycle of the honeybee in accessible, beautiful language. Similar in form and concept to the Sibert and Orbis Pictus award book Giant Squid, Honeybee also features a stunning gatefold and an essay on the plight of honeybees.A New York Public Library Best Book of the YearA Junior Library Guild Gold Standard SelectionNamed a Best Book of the Year by Kirkus Reviews, NPR, Shelf Awareness, School Library Journal, Publishers Weekly and more!A Horn Book Fanfare Best Book of the YearA Booklist Editor's Choice

"For kids 8 to 13, join the largest Arctic expedition ever undertaken--and discover the secrets hidden deep in the ice that reveal how one of the world's crucial ecosystems is changing. The Arctic is changing--fast. The once-frozen landscape is melting before our eyes, and the effects can be felt around the world. But the Arctic is also the region we know the least about. Thick ice, extreme cold, and total darkness have always prevented scientists from uncovering its secrets. Until now. This science-based guide for middle readers follows the 2019 MOSAiC expedition on the largest expedition to the Arctic ever undertaken. On board the Polarstern, a powerful ice-breaker research vessel, more than five hundred scientists from all over the world turned their attention to this mysterious region. Their mission? To let their vessel freeze in the sea ice and drift towards the North Pole in order to study how the Arctic is changing, and how these changes will affect our world."--

"Supernovae explosions are relatively rare in our galaxy, and so the few that are recorded in historical documents take on special meaning. This is a story about a supernova that appeared in the year 1054 and the Crab Nebula remnant that was created by that explosion. The supernova of 1054 was one of the brightest supernova events recorded in history. And its remnant, the Crab Nebula, is still studied today. The story begins at the moment of a supernova explosion that occurred roughly 6000 to 6500 years ago. The narrative then travels forward in time to the year 1054, when a young astronomer and the people of the Chinese court see the light of this supernova appear suddenly in Earth's sky. They called this light a 'guest star.' After a couple of years, when the light of the guest star fades, the story takes the reader into deep space to see the remnant of this supernova -- the Crab Nebula -- followed by a continuing trip forward in time. Over the remaining pages, it is revealed that the Chinese "guest star" was the light of that long-ago supernova blast, and that the Crab Nebula is that supernova's remains. At the end of the book, readers are invited to imagine a time when they, too, might see the rare event of a supernova shining in the sky."--

"Who hasn't wished for a superpower? Maybe it's to be able to regenerate like Wolverine, or fly like Shazam? How about the ability to turn invisible like Violet Parr, or have superstrength like the Hulk? What about being able to control minds like the Scarlet Witch, or even be immortal like Klaus Hargreeves? Well, grab your cape and tights, because scientists are working to replicate many of the superpowers we see in comics and movies and on television. Some are already a reality! Using popular superheroes and their powers as a starting point for imagining what could be, BECOMING BIONIC explores how science is constantly searching for and discovering new ways to augment the human body and the human experience. BECOMING BIONIC covers six aspects of superhero performance: Super Parts, Super Flight, Super Sight, Super Strength, Super Brains, and Super Survival. In each section, an illustrated timeline takes readers back in time for a fascinating look at inventions of the past. For example, in the Super Parts section, we begin with the Cairo Toe, a jointed prosethetic big toe that dates all the way back to 950-710 BCE, and end at 2012 when scientists built a "bionic man" out of 27 engineered parts. In the second spread of each section, readers zip ahead to read about some of today's amazing science that is already in use. In the Super Sight section, for example, we learn about a technology that uses radio signals to "see" through walls and can be used to uncover earthquake victims. A final spread blasts readers forward to find out what the future might have in store, such as the crustacean-inspired exoskeletons that give wearers extra strength with the help of artificial muscles that are described in the Super Strength section. Finally the book concludes with some bigger picture thoughts and questions that prompt readers to think critically about the innovations they've just read about - should science abide by a moral code and who determines what that is?"--
