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!...

Did you know that both electricity and light move in waves, like water does? What does electricity have to do with magnets? From Benjamin Franklin and Charles de Coulomb to Georg Ohm and James Joule, readers will be introduced to the basic principles of light, electricity, and magnetism in an illuminating way.

"Red Kangaroo is having a fun day at the beach! She loves watching the waves go up and down, but, suddenly, she has a question: Do the waves ever stop? Dr. Chris has the answer-not only do waves never stop, but there are all kinds of waves around us! Discover all the waves you can and can't see, plus the waves you can hear!

"Most people are probably familiar with the X-rays used in medicine, which can show organs within a body. This book explores the history of radiography and how it came to be one of the most useful tools in medicine. It also delves into the limits of radiography and the effects of ionizing radiation on living things. It further investigates many ofther uses of X-rays, including nuclear weaponry and counterfeit detection"--

Explores the science behind modern technology: TV, radio, Internet, cell phones/mobile devices, Earth to space communication, satellites, and GPS. Expands students understanding of light and sound as mechanisms of energy transfer and transfer of information between objects that are not in contact. Covers scientists and discoveries that led to modern technology.
