We grow bigger and bigger, and every few months we need new shoes and clothes. We grow taller and taller, until one day we are finally tall enough to ride on that rollercoaster. When we were born we couldn't talk or walk, but now we can read, write, use a computer, and play sports. All day, every day, we are growing and changing. Bones grow, muscles develop and get stronger, and brains develop the ability to learn all they can about the world. In What Happens When I Grow? the processes involved in growing from a baby to an elementary-school child are explored through a child's everyday life. Fascinating facts are woven into lively, accessible step-by-step explanations, delivering solid science in a way that's perfectly suited to the book's Grade 2 readership.
