STEM subjects ar e tho se that incorpor ate s cience, technology, engineering, and math. They ofte n overlap. Y o u need mathematical measure ments to collect the r esult s from a science experiment. Y o u need to write comput er pro grams to opera te the machines you have engineere d. Y o u need to unders tand the science of for ces t o be a struc tural engineer . STEM subjects ar e highly interlinke d, and many of the w ords from one subject will be useful when learning about another . Childre n will meet a lot of new wor ds wh en they begin to st udy STEM subjects at school. A gr eat d eal of technical vocabulary is used in these lessons: names fo r pieces of equipment, names for things w e cannot see (such as fo rces) , and word s that describe a specic pro perty of materials (such as opaqu e), and these may all be new to childr en. This book contains topics and w ords that childre n are likely to encounter in th eir rst f ew years at school. It also includes many of the topics th at fascinate child ren i n this age gro up, and some that show how STEM subjects ar e pr esent in our every day lives. A broad vocabulary can he lp childre n access their education more e asily. Spending time with childr en an d talking about the words and the illustr ation s in this book will ex pose them to mor e than just the w ords written here . They will encounter additional words as part of the conver sation. This book is a gr eat p lace to start your childs ST EM education.
