In Book Three of the Acadia Files series, Acadia Greene carries her search for answers into winter. A melting snowman leads her to explore climate change and how to reduce her carbon footprint. The helium balloons at her eleventh birthday party beg questions of molecular structure, weights of gases, and neutral buoyancy. An afternoon making paper airplanes brings discoveries in aerodynamics. Tracks in the snow raise questions of how animals survive winter. And an afternoon of sledding slides into an investigation of momentum, acceleration, and friction. Acadia doesn?t mean to do science?it just happens. She?s curious, determined, bold, and bright?a wonderful STEAM ambassador!

Eight-year-old Ada Lace is determined to win the robot-building competition but is struggling with her art class so she soon wonders if there might be a way to use both science and art to solve her problems.

From Emily Calandrelli—Emmy-nominated host of Xploration Outer Space, correspondent on Bill Nye Saves the World, and graduate of MIT—comes the fifth novel in a fun illustrated chapter book series about an eight-year-old girl with a knack for science, math, and solving mysteries with technology. Third grader and inventor extraordinaire Ada Lace is on spring break. But it’s just a little less relaxing than she’d imagined. Nina is beside herself with excitement about meeting her favorite artist and enlists Ada and Mr. Peebles’s coding-whiz nephew to help revamp her online portfolio. When Nina finally meets Miroir, he snubs her, and her confidence is shaken—but not enough to miss the art show opening. While there, Ada spots a suspiciously familiar painting that may mean Miroir isn’t the original he claims to be. Will the friends be able to reveal the artist’s true nature, before he fools someone else?

When Rosie Revere’s Uncle Ned gets a little carried away wearing his famous helium pants, it’s up to Ada and friends to chase him down. As Uncle Ned floats farther and farther away, Ada starts asking lots of questions: How high can a balloon float? Is it possible for Uncle Ned to float into outer space? And what’s the best plan for getting him down?

For fans of the "Who Was" series, this lively, accessible, and full-color chapter book biography shows how a self-taught scientist was the first to observe the microbial life in and around us. By building his own microscope, Antony van Leeuwenhoek advanced humanity's understanding of our oft-invisible world around us. Microbes are everywhere: in the soil and oceans, in snow, and inside our bodies. But in Antony van Leeuwenhoek's time, people believed that what they saw with their own eyes was all that existed in the world. How did a simple tradesman--who didn't go to college or speak English or Latin like all the other scientists--change everyone's minds? Proving that remarkable discoveries can come from the most unexpected people and places, this eye-opening chapter book, illustrated with lively full-color art, celebrates the power of curiosity, ingenuity, and persistence.

"Bumble bees are rather charming, buzzing from flower to flower with their furry black and yellow bodies. Depending on where you live, the bees you see might be escapees from a greenhouse or "bumble bee factory." They might even be descendants of stowaways on Viking ships. Thanks to humans, bumble bees are world travelers, spreading to countries that never hosted bumble bees before. For centuries these insects pollinated our crops. But are they pushing out native pollinators? Why are some species of bumble bees flourishing whereas others are floundering, to the point of possibly disappearing forever? Dana Church's narrative nonfiction explores these questions and tells the tale of bumble bees' history with humans. She highlights the interconnectedness of the two species, and touches on the topics of endangerment and extinction, the impact on human agriculture, bumble bee habitats and ecology, and the current crisis of bee protection. With a call to action for young people to become knowledgeable about our natural world and involved in its preservation, it's a hopeful and accessible guide to our history with these teddy bears of the insect world"--

Jordie is awed by asteroids, perplexed by planets, and mesmerized by moons. She can't believe her luck when she finds a black hole taking up residence in her desk at school. Of course she's keeping it. But when the black hole starts snarfing everything in sight--including Neptune the dog--she realizes that black holes need wide open spaces, galaxies to graze, and stars to slurp. So she sets things right. Just not before she embarking on a wild, time- and space-bending mission to save her pup.

Here comes the future! The world’s coolest technology comes to life with fun, hands-on experiments for kids.   •             Test solar power with milk jugs and balloons •             Understand genome technology with food coloring •             Launch your own “microsatellites” into orbit   These 27 terrific experiments use basic stuff from around the house and will help you understand the fascinating and potentially scary world of driverless cars, artificial intelligence, robots and androids, 3-D printing, test-tube meat, smart clothing, and more. Through cool illustrations, photos, and Sean Connolly’s clear and always-lively writing, you’ll learn what each breakthrough means, how it can improve our lives, and what its downside might be. An elevator leading into outer space? A robot that learns to think for itself? What could possibly go wrong?   Attention, parents: It’s time to put the “T” in STEM! You’ve probably heard that acronym, which stands for the core subjects of Science, Technology, Engineering, and Math. And though technology can get pretty scary in our imaginations, these experiments give your kids a hands-on understanding of the principles behind the innovations—so no, they won’t be performing laser surgery on their siblings or reprogramming the GPS in your car. (But they’ll still have fun!)
