The acronym “STEM” stands for (S)cience, (T)echnology, (E)ngineering, and (M)ath. These subjects are closely related to one another and are sometimes overlooked as critical subjects in education, often dismissed by students and teachers after primary education is completed. However, the need for these subjects in our society is crucial. The books in this series aim to pique the interest of children in these areas of study, stress the importance of these subjects, and help encourage children who are interested to continue within these fields as they grow and learn.  Between marvelous mazes, spot the difference, drawing puzzles, pattern identifying, testing quizzes, and more, the activities in this book introduce children to the science behind the world around them and might even, one day, inspire them to contribute an invention of their own.  Science is the explanation of how things work in our universe. Within this book, young scientists can discover more at home by reading the simple explanations and completing the beautiful illustrated activities on each page. Fun games and puzzles teach boys and girls the wonders of science. They’ll love the mix of nonfiction and activities in this educational book full of big ideas.
