"The Franklin Institute is like a giant science lab, albeit one with a walk-through model of the heart (claustrophobes, beware). The layout is highly interactive, whether you're stepping on a scale to learn how many pints of blood you have or climbing a webbed trail of nets that mimic the brain's pathways. The museum is almost always packed with excited kids, harried parents, and field trips. It's the domain of elementary and middle school students during the week and families on weekends." - Nancy DePalma
