You wear clothes every day, but are you aware of how much math is involved in creating the outfits you put on? How Fashion Designers Use Math colorfully illustrates how designers use math to measure, create, and produce their fashions. Concepts and skills emphasized include: • Number Sense and Operations • Problem Solving • Estimation • Measurement • Data Analysis • Algebraic Thinking • Geometry and Spatial Sense.
If you go outside on a windy day, you realize just how strong air can be. It can lift a kite high in the sky and grab onto a balloon and carry it away. But even when the air is calm, you can feel its strength and resistance when you move. "How Do Aircraft Fly?" reveals the science behind air pressure and flying everything from hot-air balloons to helicopters to jet aircraft through eye-catching full-color photograph and illustrations, as well as through textual explanations of real-world examples.
In recent years, there has been much concern about the world's reliance on nonrenewable resources, such as oil. Scientists are attempting to decrease our dependency on oil - something cars require to work. Hybrid cars, which run on alternative energy sources like sunlight, corn, and biofuels, may be the key to using less oil. "How Do Hybrid Cars Work?" discusses how these machines work, the science behind the energy they make, and what the use of hybrid cars means for the planet. Full-color photographs and illustrations keep young readers enthralled in the science behind hybrid cars.
Among recent concerns about the use of nonrenewable fuels such as oil and coal, scientists have been trying to discover alternative ways of making energy and electricity available. Sunlight is a free, unlimited resource that hits the Earth with more energy in an hour than the people of the world use in a year. The colorful "How Do Solar Panels Work?" reveals how researchers are working on ways to harness the power of sunlight through solar panels and delves into the science behind these panels.
The Moon is very far from Earth. Yet, scientists have been able to get satellites, shuttles, and other spacecraft into space and a few manned spacecraft to land on the Moon. "How Does a Spacecraft Reach the Moon?" reveals the science behind propulsion and the energy it takes to get large craft into space. Colorful photographs and illustrations, complemented by real-world examples, will ignite young readers' interest in space and the vehicles humans use to visit there.
