Matter: Physical Science for Kids from the Picture Book Science series gets kids excited about science! What’s the matter? Everything is matter! Everything you can touch and hold is made up of matter—including you, your dog, and this book! Matter is stuff that you can weigh and that takes up space, which means pretty much everything in the world is made of matter. In Matter: Physical Science for Kids, kids ages 5 to 8 explore the definition of matter and the different states of matter, plus the stuff in our world that isn’t matter, such as sound and light! In this nonfiction picture book, children are introduced to physical science through detailed illustrations paired with a compelling narrative that uses fun language to convey familiar examples of real-world science connections. By recognizing the basic physics concept of matter and identifying the different ways matter appears in real life, kids develop a fundamental understanding of physical science and are impressed with the idea that science is a constant part of our lives and not limited to classrooms and laboratories. Simple vocabulary, detailed illustrations, easy science experiments, and a glossary all support exciting learning for kids ages 5 to 8. Perfect for beginner readers or as a read aloud nonfiction picture book! Part of a set of four books in a series called Picture Book Science that tackles different kinds of physical science (waves, forces, energy, and matter), Matter offers beautiful pictures and simple observations and explanations. Quick STEM activities such as weighing two balloons to test if air is matter help readers cross the bridge from conceptual to experiential learning and provide a foundation of knowledge that will prove invaluable as kids progress in their science education. Perfect for children who love to ask, “Why?” about the world around them, Matter satisfies curiosity while encouraging continual student-led learning.

What do you do when a nuclear weapon detonates nearby? During the early Cold War years of 1945-63, Civil Defence Canada and the Emergency Measures Organization planned for just such a disaster and encouraged citizens to prepare their families and their cities for nuclear war. By the time of the Cuban Missile Crisis, the civil defence program was widely mocked, and the public was vastly unprepared for nuclear war. Canada’s civil defence program was born in the early Cold War, when fears of conflict between the superpowers ran high. Give Me Shelter features previously unreleased documents detailing Canada’s nuclear survival plans. Andrew Burtch reveals how the organization publicly appealed to citizens to prepare for disaster themselves -- from volunteering as air-raid wardens to building fallout shelters. This tactic ultimately failed, however, due to a skeptical populace, chronic underfunding, and repeated bureaucratic fumbling. Give Me Shelter exposes the challenges of educating the public in the face of the looming threat of nuclear annihilation. Give Me Shelter explains how governments and the public prepared for the unexpected. It is essential reading for historians, policymakers, and anybody interested in Canada’s Cold War home front.

"All the sizzle, chaos, noise and scariness of war is clay in the hands of ace storyteller Lynch." -- Kirkus Reviews for the World War II series Discover the secret missions behind America's greatest conflicts.Danny Manion has been fighting his entire life. Sometimes with his fists. Sometimes with his words. But when his actions finally land him in real trouble, he can't fight the judge who offers him a choice: jail... or the army.Turns out there's a perfect place for him in the US military: the Studies and Observation Group (SOG), an elite volunteer-only task force comprised of US Air Force Commandos, Army Green Berets, Navy SEALS, and even a CIA agent or two. With the SOG's focus on covert action and psychological warfare, Danny is guaranteed an unusual tour of duty, and a hugely dangerous one. Fortunately, the very same qualities that got him in trouble at home make him a natural-born commando in a secret war. Even if almost nobody knows he's there.National Book Award finalist Chris Lynch begins a new, explosive fiction series based on the real-life, top-secret history of US black ops.

But as the Korean War rages on, Fergus and his fellow divers -- AKA "frogmen" -- are tasked with more than just scouting mudflats. Soon they're planting mines. And sabotaging tunnels, bridges... and even fishing nets. Strangest of all, it falls to Fergus to transport a spy into the country -- and that means traveling far from Navy-controlled waters.But frogmen are amphibious. And Fergus may not realize it, but he's in a position to change the way the whole world thinks about combat.National Book Award finalist Chris Lynch continues his explosive fiction series based on the real-life, top-secret history of US black ops and today's heroic Navy SEALs.

Questions and answers introduce such physical phenomena as force, motion, magnetism, heat, and sound.

In 2008, Ryan Flavelle, a reservist in the Canadian Army and a student at the University of Calgary, volunteered to serve in Afghanistan. For seven months, twenty-four-year-old Flavelle, a signaller attached to the Princess Patricia’s Canadian Light Infantry, endured the extreme heat, the long hours and the occasional absurdity of life as a Canadian soldier in this new war so far from home. Flavelle spent much of his time at a Canadian Forward Operating Base (FOB), living among his fellow soldiers and occasionally going outside the wire. For one sevenday period, Flavelle went into Taliban country, always walking in the footsteps of the man ahead of him, meeting Afghans and watching behind every mud wall for a sign of an enemy combatant. The Patrol is a gritty, boots-on-the-ground memoir of a soldier’s experience in the Canadian Forces in the 21st century. It is about why we fight, why men and women choose such a dangerous and demanding job, and what their lives are like when they find themselves back in our ordinary world.

Dispersion forces acting on both atoms and bodies play a key role in modern nanotechnology. As demonstrated in this book, macroscopic quantum electrodynamics provides a powerful method for understanding and quantifying dispersion forces in a vast range of realistic scenarios. The basic physical concepts and theoretical steps allow for the derivation of outlined general expressions for dispersion forces. As illustrated by a number of examples, these expressions can easily be used to study forces between objects of various shapes and materials, including effects like material absorption, nontrivial magnetic properties and dynamical forces asssociated with excited systems.
