There’s not enough meat here to really make it a recommend, but what’s here is worthwhile.  Each two page spread consists of one full-page color photo opposite a single random fact about the human body, with a few sentences in large font to explain it.  Some of the facts are more “weird” than others, but there’s enough to trigger a response from kids (maybe disgust, maybe fascination, maybe humor).  It’s really intended for early audiences — I might be stretching it to include grade three — older readers may be interested, but not satisfied, with what they learn.
