Energy

Defined as the ability to do work, energy is one of the most crucial concepts in physical science - existing seemingly everywhere and in everything. In this book, readers will learn how energy affects the movement of objects through the air, the warmth we feel on our skin when the sun shines, and many concepts in between. Readers will also conduct energy experiments and find out how humans have learned to harness energy in different ways. Features include eye-catching sidebars; experiments and activities to encourage hands-on learning; glossaries; charts, diagrams and more.
