How Big is Big?

What is the volume of your bedroom? How much space does a ball of clay take up? Does water take up more space when it freezes? Everything around you has volume, or takes up space. The ideas in this book will help you learn what volume is and how it can be measured. Using simple materials, you can do everything a scientist does: conduct experiments, keep records, and draw conclusions from what you have learned. Many chapters also include follow-up questions and ideas that are very useful if you are interested in entering a science fair. Lots of colorful drawings make the written instructions easy-to-follow.
