Why Do Ice Cubes Float?

Water is a big part of everyday life. People wash with it, drink it, and run inside when it falls as rain. It also seems to defy the basics of physical science by floating in liquid when frozen as ice. Readers learn exactly why that is through accessible and age-appropriate language, as well as how liquid water becomes ice. Full-color photographs complement the main content, and an illustrated graphic organizer shows this common process step-by-step to help readers truly understand this science concept.
