Summary:
"Everything we can see and touch is matter-as well as some things we can't. We can tell the difference between the different kinds of matter through each one's properties, such as density, magnetism, and conductivity. Knowing about these properties and matching the right materials with the right jobs is essential for today's scientists, engineers, and inventors-and tomorrow's, too! Informative photographs and stimulating sidebars enhance the accessible text, allowing readers to connect significant science concepts to their practical applications-from constructing kitchen equipment that won't burn our hands to engineering spacecraft that will protect astronauts"-- Provided by publisher.
