In this engaging title, young readers learn how temperature works. Different temperature scales are explained, as is temperature's effect on molecules and different states of matter. These properties are illustrated by the creation, movement, and melting of glaciers. Ice ages and global warming are included, as are their effects on the delicate temperature balance of Earth. Colorful infographics make atoms, atomic structure, how the sun heats Earth, and the greenhouse effect easily accessible, and prominent contributors such as Robert Brown and Daniel Fahrenheit are featured. A fun experiment with ice brings the science of temperature to life. Aligned to Common Core Standards and correlated to state standards.
