Describes how we use balance and motion every day and explains how gravity has an effect on everything on Earth. As readers use scientific inquiry to learn the stability and instability of objects that are caused by gravity an activity based on real world situations challenges them to apply what theyve learned in order to solve a puzzle.

iScience Readers put the focus on fun and scientific enquiry. Each book introduces science fundamentals through a science puzzle and related hands-on activities. Critical thinking skills are strengthened through exploring science concepts and applying them to the real-world situation that the puzzle introduces. Three levels offer increasingly more challenging text and problem-solving activities.
