School Library JournalGr 2-4–The bold, large-scale, colorful photographs on these books’ covers are sure to draw in even the most reluctant readers. Each title focuses on a simple machine that makes our lives easier, explaining how the mechanism functions and where it can be found in everyday life. The clear texts end with the same spread defining all six machines. “Science in Action” experiments and “What Have You Learned?” quizzes (with answers provided) are included. Great additions.
