These beetles came to America from China, living in wood turned into shipping material. At first the beetles invaded urban areas, where hardwood trees were in limited supply—Chicago was able to declare itself ALB-free in 2006. But right now there is bad news in Massachusetts, New York, New Jersey, and Toronto—infestations have erupted in the area’s hardwood forests, and these beetles, while bad at flying, are very good at killing trees.Clint McFarland’s job? Stop the ALB at any cost. How do you balance the needs of residents, the impact to the environment, and an invasive species primed to wipe out entire forests? It takes the help of everyday people, such as children playing baseball at a playground, teams of beetle-sniffing dogs, and science-minded people (bug scientists and tree doctors) to eradicate this invasive pest.

    She dreamed of playing the violin, but with little money for anything but the bare essentials, it was never an option...until a music teacher named Favio Chávez arrived. He wanted to give the children of Cateura something special, so he made them instruments out of materials found in the trash. It was a crazy idea, but one that would leave Ada—and her town—forever changed. Now, the Recycled Orchestra plays venues around the world, spreading their message of hope and innovation.

    Without enough money for food, let alone school, William spent his days in the library ... and figured out how to bring electricity to his village. Persevering against the odds, William built a functioning windmill out of junkyard scraps, and thus became the local hero who harnessed the wind. Lyrically told and gloriously illustrated, this story will inspire many as it shows how—even in the worst of times—a great idea and a lot of hard work can still rock the world.

    They work hard, surrounded by top security and sworn to secrecy, until finally they take their creation far out into the desert to test it, and afterward the world will never be the same.

    All around the world -- in the sea, in the soil, in the air, and in your body -- there are living things so tiny that millions could fit on an ant's antenna. They're busy doing all sorts of things, from giving you a cold and making yogurt to eroding mountains and helping to make the air we breathe. If you could see them with your eye, you'd find that they all look different, and that they're really good at changing things into something else and at making many more microbes like themselves! From Nicola Davies comes a first exploration for young readers of the world's tiniest living organisms.

    Her parents separated when she was young, and her mother insisted on a logic-focused education, rejecting Byron’s “mad” love of poetry. But Ada remained fascinated with her father and considered mathematics “poetical science.” Via her friendship with inventor Charles Babbage, she became involved in “programming” his Analytical Engine, a precursor to the computer, thus becoming the world’s first computer programmer. This picture book biography of Ada Lovelace is a portrait of a woman who saw the potential for numbers to make art.

    Like her mother, she had a passion for science, math, and machines. It was a very good combination. Ada hoped that one day she could do something important with her creative and nimble mind.A hundred years before the dawn of the digital age, Ada Lovelace envisioned the computer-driven world we know today. And in demonstrating how the machine would be coded, she wrote the first computer program. She would go down in history as Ada Lovelace, the first computer programmer.Diane Stanley’s lyrical writing and Jessie Hartland’s vibrant illustrations capture the spirit of Ada Lovelace and bring her fascinating story vividly to life.

    With a tool belt strapped over her favorite skirt (who says you can’t wear a dress and have two kinds of screwdrivers handy, just in case?), she invents and builds amazing creations in her backyard workshop. Together with her best friend Kit, Ellie can make anything. As Kit’s birthday nears, Ellie doesn’t know what gift to make until the girls overhear Kit’s mom talking about her present—the dog Kit always wanted! Ellie plans to make an amazing doghouse, but her plans grow so elaborate that she has to enlist help from the neighbor boys and crafty girls, even though the two groups don’t get along. Will Ellie be able to pull off her biggest project yet?Illustrated with Ellie’s sketches and plans, and including backmatter with how-tos, this is full of engineering fun!

    Fractals can also be quantified mathematically. Here is an elegant introduction to fractals through examples that can be seen in parks, rivers, and our very own backyards. Readers will be fascinated to learn that broccoli florets are fractals—just like mountain ranges, river systems, and trees—and will share in the wonder of math as it is reflected in the world around us. Perfect for any elementary school classroom or library, Mysterious Patterns is an exciting interdisciplinary introduction to repeating patterns.

    They eat huge numbers of insects! That helps limit the spread of diseases and the damage that insects do to farm crops. But in recent years, large populations of little brown bats have been dying off each winter. Is a virus killing them? Could climate change or pesticides be the cause? Or is it something else? Follow a team of dedicated scientists working to save the little brown bats in this real-life science mystery.-- "Journal"

    Here are 12 "hypotheses," as well as lists of "what you need," "what to do," and "what happened" that are sure to make young readers laugh out loud as they learn how to conduct science experiments (really!). Jenny Offill and Nancy Carpenter—the ingenious pair that brought you 17 Things I'm Not Allowed to Do Anymore—have outdone themselves in this brilliant and outrageously funny book.

    The stunning and accurate drawings show these animals in all their natural majesty and the witty and charming descriptions will teach children all about their new favorite animals!Dieter Braun is a freelance illustrator and children's book author from Hamburg, Germany.

    A collection of illustrations, concrete poetry, and photographs that shows how young children's constructions, created as they play, are reflected in notable works of architecture from around the world.

    Here for a new generation of readers and explorers are the steady astronauts, clicking themselves into gloves and helmets, strapping themselves into sideways seats. Here are their great machines in all their detail and monumentality, the ROAR of rockets, and the silence of the Moon. Here is a story of adventure and discovery—a story of leaving and returning during the summer of 1969, and a story of home, seen whole, from far away.
