This short book covers alot of information–everything you wanted to know about energy, and then some.  Using aliens as the ‘spokespeople,’ this book covers the different forms of energy, where they come from and what they are used for.  Also covered is using and saving energy and taking care of our earth.  Broken into four chapters, each chapter cleverly portrays science concepts in ways that young students will understand.  This book should be included in every science kit which teaches about energy.
