Energy Transformations: Transformers at Work explains that energy is all around us—and inside us. Students learn how energy changes form and how it is used. They discover how energy can travel and, most importantly, cause changes. They learn about various types of energy, including chemical energy, electrical energy, and the energy of motion. 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 energy covered in those pages.
