    In fact, getting sick and dying can be a big, ugly mess-especially before the modern medical care that we all enjoy today. How They Croaked relays all the gory details of how nineteen world figures gave up the ghost. For example:It is believed that Henry VIII's remains exploded within his coffin while lying in state. Doctors "treated" George Washington by draining almost 80 ounces of blood before he finally kicked the bucket. Right before Beethoven wrote his last notes, doctors drilled a hole in his stomach without any pain medication.Readers will be interested well past the final curtain, and feel lucky to live in a world with painkillers, X-rays, soap, and 911.

    The stock market – the system that controls money in America – plunged to a record low. But this event was only the beginning of many bad years to come. By the early 1930s, one out of three people was not working. People lost their jobs, their houses, or both and ended up in shantytowns called “Hoovervilles” named for the president at the time of the crash. By 1933, many banks had gone under. Though the U.S. has seen other times of struggle, the Great Depression remains one of the hardest and most widespread tragedies in American history. Now it is represented clearly and with 80 illustrations in our What Was…? series.

    They battled piranhas, tigers, and vampire bats. Even the plants themselves could be lethal! But these intrepid eighteenth- and nineteenth-century explorers were determined to find and collect new and unusual specimens, no matter what the cost. Then they tried to transport the plants—and themselves—home alive. Creating an important legacy in science, medicine, and agriculture, the plant hunters still inspire the scientific and environmental work of contemporary plant enthusiasts.Working from primary sources—journals, letters, and notes from the field—Anita Silvey introduces us to these daring adventurers and scientists. She takes readers into the heart of their expeditions to then-uncharted places such as the Amazon basin, China, and India. As she brings a colorful cast of characters to life, she shows what motivated these Indiana Jones–type heroes. In The Plant Hunters, science, history, and adventure have been interwoven to tell a largely forgotten—yet fascinating—story.

    Full of striking, singular art, this collection also contains infographics about relevant topics such as lab equipment, rates of women currently working in STEM fields, and an illustrated scientific glossary. The women profiled include well-known figures like primatologist Jane Goodall, as well as lesser-known pioneers such as Katherine Johnson, the African-American physicist and mathematician who calculated the trajectory of the 1969 Apollo 11 mission to the moon.

    For Apollo 11, the first moon landing, is a story that belongs to many, not just the few and famous. It belongs to the seamstress who put together twenty-two layers of fabric for each space suit. To the engineers who created a special heat shield to protect the capsule during its fiery reentry. It belongs to the flight directors, camera designers, software experts, suit testers, telescope crew, aerospace technicians, photo developers, engineers, and navigators.Gathering direct quotes from some of these folks who worked behind the scenes, Catherine Thimmesh reveals their very human worries and concerns. Culling NASA transcripts, national archives, and stunning NASA photos from Apollo 11, she captures not only the sheer magnitude of this feat but also the dedication, ingenuity, and perseverance of the greatest team ever—the team that worked to first put man on that great gray rock in the sky.

    As she turns the pages in this book about coral reefs, the city around her slips away and she finds herself surrounded by the coral cities of the sea and the mysterious plants and animals that live, hunt, and hide there.

Aimed at middle grade students, Stormy Seas combines a contemporary collage-based design, sidebars, fact boxes, timeline and further reading to produce a book that is ideal for both reading and research. Readers will gain new insights into a situation that has constantly been making the headlines.

    In over fifty dramatic, full-color photographs and an easy-to-read text, award-winning author Seymour Simon takes you on a fascinating tour of the nine planets, dozens of moons, and thousands of asteroids, meteoroids, and comets that travel around our sun.First, Simon explores the star at the center of our Solar System -- from the constant nuclear explosions at its core to the giant storms on its surface as geysers of flaming gas over a hundred thousand miles long rise and fall in just a few hours.You will also learn about the four rocky inner planets, from airless Mercury to fiery Venus, her sister planet, Earth, and mysterious Mars. Then join the thrilling Voyager missions to explore the four gaseous outer planets: gigantic Jupiter, ringed Saturn, tilted Uranus -- the planet "lying on its side" -- and windy Neptune. You will finish your journey at distant Pluto, then visit the asteroid belt and examine comets, the "dirty snowballs" in space.A companion volume to Simon's landmark series of individual books about each of the planets, the sun, stars, and other space sights, Our Solar System will introduce you to some of the most amazing mysteries in the universe.

    Katherine Johnson was one of these mathematicians who used trajectories and complex equations to chart the space program. Even as Virginia’s Jim Crow laws were in place in the early 1950s, Katherine worked analyzing data at the NACA (later NASA) Langley laboratory. In 1962, as NASA prepared for the orbital mission of John Glenn, Katherine Johnson was called upon and John Glenn said “get the girl” (Katherine Johnson) to run the numbers by hand to chart the complexity of the orbital flight. He knew that his flight couldn’t work without her unique skills. President Barack Obama awarded Katherine Johnson the Presidential Medal of Freedom in 2015 and her incredible life inspired the Oscar-nominated film Hidden Figures. Get to know this incredible and inspirational woman with this beautifully illustrated picture book from an award-winning duo.

    Bugs, of all kinds, were considered to be “born of mud” and to be “beasts of the devil.”  Why would anyone, let alone a girl, want to study and observe them? One of the first naturalists to observe live insects directly, Maria Sibylla Merian was also one of the first to document the metamorphosis of the butterfly. In this nonfiction biography, illustrated throughout with full-color original paintings by Merian herself, author Joyce Sidman paints her own picture of one of the first female entomologists and a woman who flouted convention in the pursuit of knowledge and her passion for insects.
