Binoculars

"Having trouble seeing something far away? Well, you may need a pair of binoculars! This book investigates the pieces of a pair of binoculars and explains how they combine to magnify far away objects. You won't need a pair of binoculars to read this book, but it's sure to be a topic you'll want to learn more about. This book will allow students to make observations and/or measurements of an object's motion to provide evidence that a pattern can be used to predict future motion"--Page 4 of cover.
