The supercharged facts about energy and waves can set your brain buzzing! You learn about huge rates of consumption (like the 35.3 quadrillion BTUs of petroleum used in the United States in 2011), huge timelines (it took 300 million years for our greatest source of energy, fossil fuels, to be created), and even huger mysteries (how long it will be before fossil fuels run out).How can all these big numbers and concepts make more sense? Infographics! The charts, maps, and illustrations in this book tell a visual story to help you better understand key concepts about energy and waves. Crack open this book to explore mind-boggling questions such as: • What is “the grid” and how does it work? • How does sound travel? • How can dancing create energy? The answers are sure to be shocking!

Learning about heavy physics concepts can sure weigh down your brain! You need to understand huge forces (like gravity, magnetism, and inertia), huge speeds (light moves at 670,615,200 miles per hour), and even huger mysteries (what space-time is). How can all these big numbers and concepts make more sense? Infographics! The charts, maps, and illustrations in this book tell a visual story to help you better understand key concepts about forces and motion. Crack open this book to explore mind-boggling questions such as: • How do spaceships break away from Earth''s gravity? • Why don''t submarines and ships sink in water? • What keeps riders from falling out of roller coasters (besides their safety belts!)? The answers are sure to stick with you!

Trying to breeze through weather and climate facts just might cause a brain freeze! You''re showered with details about extreme temperatures (Earth''s record high is 134°F and record low is -129°F), crazy heights (our atmosphere extends 6,200 miles above Earth), and even huger mysteries (how predictions in weather and climate work). How can all these big numbers and concepts make more sense? Infographics! The charts, maps, and illustrations in this book tell a visual story to help you better understand key concepts about weather and climate. Crack open this book to explore mind-boggling questions such as: • How do cold and warm fronts change weather? • How can cities at similar latitudes have significantly different climates? • How do ocean currents help create winds, temperature changes, and storms? The answers are sure to blow you away!

When John F. Kennedy became the youngest person ever elected president of the United States in 1961, he stepped to the forefront of an invisible battleground. The Cold War standoff between America and the Soviet Union threatened to lead to nuclear war and worldwide destruction. Kennedy also faced domestic turmoil with the civil rights movement. Despite these challenges, Kennedy worked to bring the country into a "New Frontier." He supported space exploration, the arts, education, and groundbreaking social programs. He took a controversial stand in favor of civil rights legislation, and navigated dangerous webs of foreign affairs. Kennedy inspired the nation with his hopes for the future and his efforts to make them a reality.
