Heat: Energy That Flows introduces students to the concept of heat and guides them to an understanding of the characteristics of heat energy. Students learn that the motion of molecules, which speed up or slow down as energy is added or taken away, determines whether something is warmer or cooler. Students also learn how substances heat up and cool down as a result of the flow of heat energy and how temperature is measured. Through everyday examples, students discover how heat is transferred by conduction, convection, and radiation. At the end of each two-page spread, a brief statement called The Bottom Line reinforces students’ understanding by summing up the key ideas about heat covered in those pages.
