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 aim of this book is 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. Whether it’s through marvelous mazes, puzzles, testing, quizzes, and other fun activities, this book introduces children to the inner-working of the world around them and might even, one day, inspire them to contribute an invention or a theory of their own.
