In this science project book, the author offers older students 16 plans…”to construct and explore working models that generate renewable energy.”  The directions are easy to follow; black-and-white simple photos help to visually depict the steps.  Safety is one-page addressed.  (Note:  Quite a few of these projects involve cutting, soldering, sawing, etc.  The young scientists must pay heed to the author’s Safety First section.  I wish the author had stated the need for adult help or adult supervision depending upon the age and ability of the young scientist.)  Each project includes a Materials and Tools list (websites are given on where to find specialized items) and  More to Think About questions.  Although the presentation of the book is not handsome, it is straightforward.  The topic is definitely current and relevant for today’s students.
