Over 7,000 years ago Native Americans settled on the Nashua River, a beautiful and leafy valley. But the industrialization of nearby areas would lead to the deterioration of natural habitats. Each double spread examines brief periods of time when the river and surrounding areas teemed with wildlife. Lynne Cherry’s contrasting illustrations of the lush valley and the eventual polluted river deliver an astonishing look at our dramatic need for conservation efforts. This pictorial history of the river, edging towards a hopeful scene of modern-day descendants of both Native Americans and European settlers who come together to combat pollution and restore the beauty of the river, is an intelligent tale that shows young readers how they can do their part in taking care of the world around them, one river at a time.

    Nathaniel Bowditch grew up in a sailor’s world—Salem in the early days, when tall-masted ships from foreign ports crowded the wharves. But Nat didn’t promise to have the makings of a sailor; he was too physically small. Nat may have been slight of build, but no one guessed that he had the persistence and determination to master sea navigation in the days when men sailed only by “log, lead, and lookout.” Nat’s long hours of study and observation, collected in his famous work, The American Practical Navigator (also known as the “Sailors’ Bible”), stunned the sailing community and made him a New England hero.

    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.

    Using the insights of great mathematicians and endlessly observing the sky, he succeeded in confirming two things that altered human life forever: that there are more galaxies than our own, and that the universe is always expanding. Hubble’s message to us is to find peace in the vastness of the mystery surrounding us, and to be curious. “We do now know why we are born into the world,” he said, “but we can try to find out what sort of world it is.”

    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.
