Remember the uproar over the unidentified Chinese cadavers in "Bodies: The Exhibition"? "Our Body: The Universe Within" is the family-friendly version. In April, the traveling exhibit brings 200 preserved human bodies to the newly opened and expanded Lakeside Pavillion at the ECHO Lake Aquarium and Science Center. The online "Family Outing" guide offers tips to prepare kids for the experience, including fun facts: Did you know babies have 300 bones at birth, but 206 later on? Don't let the anatomical correctness scare you; it's too good a learning experience to pass up. ECHO is collaborating on this one with the UVM College of Medicine, which has provided additional videos. "This is a unique and powerful way for folks to experience for themselves the wonders of the human body," says ECHO executive director Phelan Fretz.
